\"L-25A\"L-25A\"L-25A<\/p>\n

Key Benefits of the L-25A Fertilizer Spreader Gearbox 1:1.35<\/h2>\n

1. Enhanced Precision and Variable Ratio Control
\nL-25A:n suunniteltu 1:1,35 lannoitteenlevittimen vaihteiston v\u00e4lityssuhde tarjoaa kalibroidun nopeudenmuunnoksen tasaiselle ja yhdenmukaiselle lannoitteen levitykselle jokaisella ajokerralla. Muuttuvan v\u00e4lityssuhteen kokoonpanot auttavat kuljettajia hienos\u00e4\u00e4t\u00e4m\u00e4\u00e4n levitysm\u00e4\u00e4ri\u00e4 tiettyjen viljelykasvien, maaper\u00e4tyyppien ja pelto-olosuhteiden mukaan, mik\u00e4 v\u00e4hent\u00e4\u00e4 ylilevityst\u00e4 ja panoskustannusten hukkaa. Tarkka v\u00e4\u00e4nt\u00f6momentin hallinta tarkoittaa, ettei kuumia kohtia tai paljaita l\u00e4iski\u00e4 synny, mik\u00e4 suojaa sek\u00e4 satoa ett\u00e4 budjettia koko kasvukauden ajan.<\/p>\n

2. Exceptional Durability in Harsh Conditions
\nBuilt with a precision die-cast aluminium housing, this fertilizer gearbox delivers outstanding corrosion resistance against aggressive chemical fertilisers, moisture, and field debris. Robust seals and quality bearings protect internal gearing from abrasive wear, while the sealed design prevents contamination ingress during wet-weather field operations. At just 4.1 kg, the lightweight aluminium body reduces machine load without sacrificing structural strength or service life.<\/p>\n

3. Optimised Fuel Efficiency
\nL-25A:n sis\u00e4isesti optimoitu hammaspy\u00f6r\u00e4st\u00f6 minimoi energiah\u00e4vikin voimansiirron aikana traktorin voimanottoakselilta ja v\u00e4hent\u00e4\u00e4 siten traktorin moottorin loisvastusta. Suurimman tehon ollessa 8,1 kW ja tehon ollessa 9,9 kW, suuremman v\u00e4lityssuhteen ansiosta suurempi osa moottorin tehosta saavuttaa levitysmekanismin. Pienempi mekaaninen kitka tarkoittaa pienemp\u00e4\u00e4 polttoaineenkulutusta hehtaaria kohden levityksess\u00e4, mik\u00e4 tuottaa mitattavia k\u00e4ytt\u00f6kustannuss\u00e4\u00e4st\u00f6j\u00e4 koko kasvukauden ajan kaikenkokoisille tiloille.<\/p>\n

4. Wide Versatility Across Applications
\nT\u00e4m\u00e4 lannoitteenlevittimille tarkoitettu vaihteisto ei rajoitu pelk\u00e4st\u00e4\u00e4n rakeisiin lannoitteisiin. Sen kest\u00e4v\u00e4 rakenne k\u00e4sittelee nestem\u00e4isi\u00e4, pelletoituja ja orgaanisia lis\u00e4aineita yht\u00e4 tehokkaasti, ja se on my\u00f6s mitoitettu k\u00e4ytett\u00e4v\u00e4ksi ruohonleikkureissa ja vannesahoissa, mik\u00e4 tekee siit\u00e4 monipuolisen investoinnin. Standardoitu 1 tuuman 3\/8 Z6-voimanottoakselin tuloliit\u00e4nt\u00e4 varmistaa laajan yhteensopivuuden traktorin kanssa, ja ulostuloakselin mitat vastaavat Comer L-25A -jalanj\u00e4lke\u00e4, mik\u00e4 mahdollistaa helpon alkuper\u00e4isvalmistajan vaihdon useissa levitinmerkeiss\u00e4.<\/p>\n

5. V\u00e4h\u00e4inen huoltotarve
\nInternal oil-bath lubrication, combined with a maximum oil change interval of 500 operating hours, dramatically reduces downtime and labour costs. The modular component layout makes access to bearings, seals, and gears straightforward for routine service. A simple SAE 80W-90 fill (max 0.35 L) is all that is required at commissioning. With clearly defined service intervals and readily available fertilizer spreader gearbox parts, operators can plan maintenance around the farming calendar rather than responding to breakdowns.<\/p>\n

6. Direct Comer L-25A -korvausyhteensopivuus
\nCMN Transmissionin versio on suunniteltu Comer L-25A:n tarkaksi korvaajaksi, ja se vastaa kaikkia kriittisi\u00e4 kiinnitysmittoja, akselikonfiguraatioita (X, Y, Z) ja laippakuvioita.

Working Principle<\/h2>\n

L-25A-lannoitteenlevittimen vaihteisto saa py\u00f6rimisenergian suoraan traktorin voimanottoakselilta, ja se toimii tyypillisesti nopeudella 540 rpm. Sis\u00e4isesti suunnitellun kartiopy\u00f6r\u00e4st\u00f6n avulla (alennusvaiheet 3-4) yksikk\u00f6 muuntaa t\u00e4m\u00e4n sy\u00f6tt\u00f6nopeuden suhteessa 1:1,35, mik\u00e4 nostaa l\u00e4ht\u00f6nopeutta ja tuottaa tasaisen, korkeamman lautasen tai ruuvin kierrosluvun ilman voimansiirtolinjan ylikuormitusta. Suurin 8,1 kW:n sy\u00f6tt\u00f6teho muunnetaan tehokkaasti 9,9 kW:n tehoksi (13,5 hv), mik\u00e4 tuottaa tarvittavan v\u00e4\u00e4nt\u00f6momentin levityslautasten k\u00e4ytt\u00e4miseen raskaiden raem\u00e4\u00e4rien, kosteiden olosuhteiden tai tihe\u00e4n orgaanisen materiaalin l\u00e4pi.

Although the L-25A operates as a direct-drive unit, it is designed for use within well-specified power limits (max 8.1 kW input) to prevent overload damage. In practice, the upstream PTO driveline incorporating slip clutches or shear bolt protection devices on the connecting PTO shaft interrupts torque if the spreading mechanism encounters a blockage, a large stone, or a sudden jamming event, shielding the fertilizer gearbox internals from catastrophic impact loads. The oil-bath lubrication system doubles as a thermal buffer, absorbing and dissipating heat generated during sustained spreading operations on long field passes. This combination of passive thermal management and upstream mechanical protection means the gearbox can reliably operate through full-day spreading sessions across large agricultural properties without risk of premature failure. Service intervals are straightforward: change oil after the first 50 to 70 hours and thereafter every 500 hours or annually, whichever occurs first, ensuring sustained reliable performance across many seasons of continuous agricultural use.<\/p>\n

In livestock operations, even fertiliser coverage across pastures is critical for maintaining consistent forage quality and grass density. The L-25A\u00a0agricultural gearbox for fertilizer spreader\u00a0use drives spreading discs at the right speed to achieve uniform distribution of urea, lime, and blended fertilisers, supporting healthy sward regeneration, improved carrying capacity, and better animal nutrition outcomes across grazing paddocks.<\/p>\n

Hedelm\u00e4tarhat ja viinitarhat<\/h3>\n

Precision spreading around established fruit tree and vine root zones is critical to avoid fertiliser burn, soil acidification, or root damage from over-application. The L-25A\u00a0agricultural gearbox\u00a0powers inter-row fertiliser spreaders used in high-value permanent crop systems including apples, grapes, citrus, and stone fruits, where accurate placement of granular fertiliser within the root zone directly impacts fruit quality, colour development, and annual yield.<\/p>\n

Kasvinviljely<\/h3>\n

Essential for the uniform application of nitrogen, phosphorus, and potassium-based fertilisers across grain crops, vegetables, pulses, and fruit orchards. Precise spreading at the correct\u00a0fertilizer spreader gearbox ratio\u00a0ensures optimal nutrient uptake per hectare, maximising yields and reducing fertiliser input waste. Suitable for both pre-planting broadcast applications and in-season top dressing across all major staple crops.<\/p>\n<\/div>\n

\n

Nurmikon ja nurmikon hoito<\/h3>\n

Golf courses, sports stadiums, racecourses, and municipal parks require precision fertiliser delivery to maintain playing surface quality. The L-25A\u00a0fertiliser spreader gearbox\u00a0enables calibrated, low-rate spreading ideal for slow-release granular fertilisers used on fine turf. Its smooth speed output eliminates streaking or uneven application that can cause discolouration or turf inconsistencies on high-profile playing surfaces.<\/p>\n<\/div>\n

\n

Puutarha- ja taimitarhat<\/h3>\n

Kasvihuoneviljely ja kaupalliset taimitarhat vaativat tarkkaa, pienille alueille suunnattua lannoitteen levityst\u00e4 ruukkukasveille ja koristekasvipenkeille. L-25A:n luotettava teho tekee siit\u00e4 tehokkaan pienimuotoisten lautaslevittimien k\u00e4yt\u00f6n, jotka levitt\u00e4v\u00e4t kontrolloidut m\u00e4\u00e4r\u00e4t hitaasti vapautuvia rakeisia lannoitteita, kontrolloidusti vapautuvia pellettej\u00e4 tai orgaanisia biostimulantteja ruukkukasveille ja kohopenkkeihin ilman liikalevityksen riski\u00e4.<\/p>\n<\/div>\n

6. \u00d6ljytiivisteet
\nRadial lip seals fitted at each shaft exit point prevent internal SAE 80W-90 gear oil from leaking out and block the entry of external contaminants including water, fertiliser dust, and abrasive soil particles. The seals are manufactured from oil-resistant elastomer compounds specifically formulated for long-term compatibility with gear lubricants in agricultural conditions. Regular inspection of fertilizer spreader gearbox oil level and seal integrity is recommended during each major service interval to detect early wear.<\/p>\n

7. Oil Fill, Level, and Drain Plugs
\nDedicated plugs on the gearbox housing allow easy oil filling to the 0.35 L capacity mark, level checking, and clean oil drainage during scheduled changes. Correct fertilizer spreader gearbox oil level maintenance is critical to gear and bearing longevity. The plugs are positioned for accessible service without removing the gearbox from the machine, reducing service time.

Gearbox Overheating During Operation
\nExcessive heat build-up in the fertilizer gearbox is most commonly caused by insufficient oil level, incorrect oil viscosity, or an oil that has degraded beyond its service life. First, stop the machine and allow the unit to cool. Check the fertilizer spreader gearbox oil level through the level plug and top up to the correct mark with SAE 80W-90 if low. If oil is discoloured (dark brown or black) or contaminated with water, perform an immediate oil change. If overheating persists after correct oil fill, inspect the gear mesh for signs of abnormal wear or a damaged bearing.<\/p>\n

Irrota tarkastuskansi ja tarkista, onko vaihteissa lohjenneita tai sy\u00f6pyneit\u00e4 hampaita. Jos sis\u00e4isi\u00e4 vaurioita vahvistetaan, on suositeltavaa vaihtaa vaurioituneet laakerit tai hammaspy\u00f6r\u00e4t lannoitteenlevittimen vaihteiston osaluettelosta ennen t\u00f6iden jatkamista.<\/p>\n

Oil Leakage Around Shaft Seals
\nOil seeping from around the input or output shaft exit points indicates a worn or damaged radial lip seal. This is a common wear item on any fertiliser spreader gearbox operating in dusty or chemically harsh environments. Replace the relevant shaft seal using a seal driver tool appropriate to the shaft diameter. Clean all mating surfaces before fitting the new seal to ensure a proper seat. Overfilling the gearbox beyond the 0.35 L maximum capacity can also cause pressure build-up that pushes oil past otherwise healthy seals, so always verify correct fill volume after topping up.<\/p>\n

Spreader Disc Speed Inconsistency
\nIf the spreading discs are running at variable or reduced speed compared to normal operation, the first check should be tractor PTO shaft engagement and the condition of the connecting PTO driveshaft universal joints, which can seize or wear if lubrication is neglected. Internally, check that the fertilizer spreader gearbox ratio is producing the expected output speed by measuring output shaft RPM with a tachometer. Low output speed at correct PTO input speed may indicate worn bevel gear teeth, which require gear set replacement to restore normal performance.<\/p>\n

Mounting Looseness or Vibration at Spreader Frame
\nPhysical looseness of the gearbox on its mounting frame leads to driveline vibration, accelerated bearing wear, and eventual gear misalignment. Inspect all four mounting flange bolts (M10 or equivalent to match the 11 mm hole pattern) for correct torque specification. Thread-locking compound applied to mounting bolts is advisable in high-vibration applications. If the mounting flange face shows signs of fretting corrosion or surface damage from prolonged loose mounting, clean and treat the contact surfaces before re-torquing to prevent recurrence of the looseness issue.<\/p>\n

Fertiliser Contamination of Gearbox Oil
\nWater-mixed fertiliser solutions or hygroscopic granular materials can draw moisture into the gearbox if seals are compromised, leading to oil emulsification and loss of lubricating film strength. Milky or grey-coloured oil at the drain is a clear indicator of water contamination. Drain and flush the gearbox, replace the contaminated oil with fresh SAE 80W-90, and identify the moisture ingress point, typically a worn shaft seal or a cracked housing. Timely attention prevents corrosive damage to polished gear tooth surfaces and bearing raceways.<\/p>\n

\"Lannoitteenlevittimen<\/p>\n

Correct Maintenance of the L-25A Fertilizer Spreader Gearbox<\/h2>\n
\n

Step 1: Initial Oil Fill Before First Use<\/h3>\n

The L-25A\u00a0fertilizer spreader gearbox\u00a0is supplied dry, without oil. Before the first operation, fill through the top fill plug with the correct SAE 80W-90 gear oil to the level plug mark (maximum 0.35 L). Use only the specified viscosity grade to ensure the oil film is adequate for the gear mesh contact pressures at 540 RPM input. Using incorrect oil viscosity is the leading cause of premature gear tooth surface fatigue in agricultural gearbox applications.<\/p>\n<\/div>\n

\n

Step 2: First Oil Change at 50 to 70 Hours<\/h3>\n

After the initial 50 to 70 operating hours, perform the first oil change. During break-in, small metallic wear particles from the bedding-in of gear tooth surfaces accumulate in the oil. Draining and replacing the oil at this interval removes these particles before they can act as abrasive cutting agents, significantly extending internal component life. Warm the gearbox slightly before draining to improve oil flow and particle suspension. Refill to the level plug mark with fresh SAE 80W-90.<\/p>\n<\/div>\n

\n

Step 3: Regular Oil Changes Every 500 Hours or Annually<\/h3>\n

After the initial change, replace the SAE 80W-90 gear oil every 500 operating hours or at least once per year, whichever comes first. This ensures lubricant additive packages for corrosion protection and extreme-pressure resistance remain effective. At each oil change, inspect the drained oil colour and clarity. Dark brown or grey oil indicates oxidation or water contamination, requiring investigation of seal integrity before the next spreading season. The 500-hour interval aligns conveniently with annual seasonal service schedules for most farming operations.<\/p>\n<\/div>\n

\n

Step 4: Inspect and Clean External Housing<\/h3>\n

After each spreading session, clean fertiliser residue, chemical deposits, and mud from the external surfaces of the aluminium housing. Concentrated fertiliser salts, particularly ammonium nitrate or urea-based products, are corrosive to aluminium if allowed to dry on the surface over extended periods. A low-pressure water rinse followed by drying is sufficient for routine cleaning. Inspect mounting bolts, shaft seal areas, and the housing surface for cracks, corrosion pitting, or mechanical damage that could compromise structural integrity or oil containment during the next operation.<\/p>\n<\/div>\n

\n

Step 5: Check Shaft Seal Condition<\/h3>\n

Inspect input and output shaft lip seals for oil weeping, cracking, or hardening at each seasonal service. A thin film of oil on the outside of the shaft near the seal exit point is an early warning sign that seal replacement is needed within the next operating period. Replace seals proactively at the first sign of degradation, as a failed seal allows both oil loss and contaminant ingress. When replacing seals, always use a proper seal driver sized to the specific shaft diameter to avoid cocking or distorting the new seal lip during installation.<\/p>\n<\/div>\n

Selecting the right PTO shaft to pair with the L-25A fertilizer spreader gearbox for sale is as important as the gearbox selection itself. The PTO shaft must be rated for at least the maximum power transmitted (8.1 kW at 540 RPM), with an appropriate safety factor for shock loads at PTO engagement. Length must be checked against the tractor-to-spreader distance at both minimum and maximum hitch extension, to ensure the shaft never bottoms out its telescopic tube or over-extends and separates. PTO shafts should incorporate a slip clutch or shear bolt protection device between the shaft and the gearbox input to interrupt torque if the spreading mechanism jams, protecting both the gearbox internals and the tractor PTO clutch from overload damage.<\/p>\n\n\n\n

\"Lannoitteenlevittimen<\/p>\n

Usein kysytyt kysymykset<\/h2>\n

Q1: Is the CMN L-25A a direct replacement for the Comer L-25A gearbox?<\/strong>
\nA: Yes. The CMN Transmission L-25A fertilizer spreader gearbox is engineered as a direct OEM-equivalent replacement for the Comer L-25A unit. All critical dimensions including the mounting flange bolt hole pattern (N.4 x diameter 11 mm), shaft diameters, and shaft lengths are matched to the original Comer specification. No machine frame modification, adaptor plates, or shaft machining is required for a standard direct swap installation.<\/p>\n

Q2: What oil should I use in the L-25A fertilizer spreader gearbox?<\/strong>
\nA: The L-25A requires SAE 80W-90 gear oil with a maximum fill capacity of 0.35 litres. Use a mineral or synthetic EP (Extreme Pressure) gear oil meeting GL-4 or GL-5 specifications. Do not use engine oil, hydraulic oil, or grease as a substitute. Using the correct viscosity grade is critical for maintaining the protective lubricant film between bevel gear tooth surfaces at 540 RPM input speed. If operating in extreme low-temperature environments, consult CMN Transmission for alternative viscosity recommendations.<\/p>\n

Q3: What is the correct fertilizer spreader gearbox oil level check procedure?<\/strong>
\nA: To check the fertilizer spreader gearbox oil level, ensure the machine is parked on level ground and the gearbox has cooled from operating temperature. Remove the oil level plug (located on the side of the housing) and check that oil is present up to the bottom of the level plug hole thread. If oil does not reach the level plug, add SAE 80W-90 through the top fill plug until oil begins to weep from the level plug hole, then refit both plugs securely. Never overfill beyond the level plug as excess oil creates internal pressure that can blow out shaft seals.<\/p>\n

Q4: What fertilizer spreader gearbox ratio does the L-25A have, and what does it mean for spreading?<\/strong>
\nA: The L-25A has a 1:1.35 fertilizer spreader gearbox ratio. This is a speed-increasing ratio, meaning for every one revolution of the input shaft, the output shaft turns 1.35 times. At standard 540 RPM PTO input, the output shaft turns at approximately 729 RPM. This faster output speed drives spreading discs at a higher rotational velocity, increasing the centrifugal throw force on the fertiliser particles and achieving greater spreading width compared to a 1:1 direct drive gearbox, without requiring a higher tractor PTO speed.<\/p>\n

Q5: Can the L-25A handle liquid fertilizers as well as granular products?<\/strong>
\nA: The L-25A agricultural gearbox is designed to drive the mechanical spreading mechanism, not to contact the fertiliser product directly. Its aluminium housing and sealed shaft design resist external exposure to fertiliser splatter from both granular and liquid product applications. For liquid fertiliser spreading systems using disc or boom spreaders, the gearbox performs the same power transmission function as in granular spreading. Ensure the external housing and seals are rinsed after liquid fertiliser sessions to prevent extended chemical contact with the housing surfaces.<\/p>\n

Q6: How long does the L-25A fertilizer spreader gearbox last under normal farm use?<\/strong>
\nA: Under normal agricultural operating conditions with the prescribed oil changes (initial at 50 to 70 hours, then every 500 hours or annually), the L-25A fertilizer distributor gearbox is designed for a service life of several thousand operating hours. Actual longevity depends on operating within rated power limits, maintaining correct PTO shaft alignment, using the specified SAE 80W-90 oil, and adhering to the maintenance schedule. Operators who follow the recommended service routine consistently report gearboxes running well beyond 1,000 hours before requiring internal component attention.<\/p>\n

Q7: What shaft configurations are available for the L-25A?<\/strong>
\nA: Comerin luettelossa yksityiskohtaisesti kuvattu ja CMN Transmissionin yhteensovittama L-25A-perhe on saatavana useilla akselikokoonpanoilla. Tuloakseliin (X) sopii 1 tuuman 3\/8 Z6 kuusiurainen voimanottoakseliliit\u00e4nt\u00e4 tai 25 mm:n lieri\u00f6m\u00e4inen akseli kokoonpanosta riippuen. Ulostuloakseleita (Y- ja Z-asennot) on saatavana 1 tuuman 3\/8 Z6-uraisena, 22 mm:n tai 25 mm:n lieri\u00f6m\u00e4isen\u00e4 muotona eri pituuksina, mik\u00e4 mahdollistaa sovittamisen erilaisiin levityslautasten navan liit\u00e4nt\u00f6ihin. Ota yhteytt\u00e4 CMN Transmissioniin varmistaaksesi levitinmallisi vaatiman tarkan akselikokoonpanon ennen tilaamista.<\/p>\n

Q8: Is a PTO shaft included with the L-25A gearbox purchase?<\/strong>
\nA: No, the L-25A fertilizer gearbox is supplied as a standalone unit without a PTO driveshaft. The connecting PTO shaft must be selected separately based on the tractor-to-machine distance and power requirements. CMN Transmission can advise on compatible PTO shaft specifications on request. When selecting a PTO shaft for use with the L-25A, ensure it is rated for at least the maximum 8.1 kW input power and incorporates a slip clutch or shear bolt overload protection device for safe operation.<\/p>\n

Q9: Where can I buy the L-25A fertilizer spreader gearbox and what is the lead time?<\/strong>
\nA: The L-25A fertilizer spreader gearbox for sale is available to order directly from CMN Transmission through this product page, or via our authorised distributor network in the United States, Canada, Europe, Australia, and other major agricultural markets. Standard lead time for in-stock units is 1 to 3 business days for domestic orders, with international shipping times varying by destination.

L-25A Fertilizer Spreader Gearbox Dimensions<\/h2>\r\n\"L-25A \"L-25A \"L-25A\r\n

Key Benefits of the L-25A Fertilizer Spreader Gearbox 1:1.35<\/h2>\r\n1. Enhanced Precision and Variable Ratio Control\r\nThe L-25A's engineered 1:1.35 fertilizer spreader gearbox ratio provides calibrated speed conversion for even, consistent fertilizer distribution across every pass. Variable-ratio configurations help operators fine-tune application rates to specific crops, soil types, and field conditions, reducing over-application and input cost waste. Precise torque management means no hot spots or bare patches, protecting both yield and budget throughout the growing season.\r\n\r\n2. Exceptional Durability in Harsh Conditions\r\nBuilt with a precision die-cast aluminium housing, this fertilizer gearbox delivers outstanding corrosion resistance against aggressive chemical fertilisers, moisture, and field debris. Robust seals and quality bearings protect internal gearing from abrasive wear, while the sealed design prevents contamination ingress during wet-weather field operations. At just 4.1 kg, the lightweight aluminium body reduces machine load without sacrificing structural strength or service life.\r\n\r\n3. Optimised Fuel Efficiency\r\nThe L-25A's internally optimised gear mesh minimises energy loss during power transfer from the tractor PTO, reducing parasitic drag on the tractor engine. With a maximum input of 8.1 kW and an output of 9.9 kW, the step-up ratio ensures more of the engine's power reaches the spreading mechanism. Lower mechanical friction means reduced fuel consumption per hectare spread, delivering measurable operating cost savings over an entire cropping season for farms of any scale.\r\n\r\n4. Wide Versatility Across Applications\r\nThis gearbox for fertilizer spreader machines is not limited to granular fertilisers. Its robust design handles liquid, pelletised, and organic amendments with equal effectiveness, and it is also rated for use in mowers and band saws, making it a multi-application investment. The standardised 1\" 3\/8 Z6 PTO input interface ensures broad tractor compatibility, while the output shaft dimensions match the Comer L-25A footprint for straightforward OEM replacement across multiple spreader brands.\r\n\r\n5. Low Maintenance Design\r\nInternal oil-bath lubrication, combined with a maximum oil change interval of 500 operating hours, dramatically reduces downtime and labour costs. The modular component layout makes access to bearings, seals, and gears straightforward for routine service. A simple SAE 80W-90 fill (max 0.35 L) is all that is required at commissioning. With clearly defined service intervals and readily available fertilizer spreader gearbox parts, operators can plan maintenance around the farming calendar rather than responding to breakdowns.\r\n\r\n6. Direct Comer L-25A Replacement Compatibility\r\nEngineered as a precision drop-in replacement for the Comer L-25A, CMN Transmission's version matches all critical mounting dimensions, shaft configurations (X, Y, Z), and flange patterns. This means zero machine modification is required during installation, eliminating costly downtime for machinery re-engineering. As trusted fertilizer spreader suppliers, CMN Transmission stocks this unit ready to ship globally, with full technical support available to ensure your spreader returns to productive field work as quickly as possible.\r\n\r\n\"L-25A\r\n

Working Principle<\/h2>\r\nThe L-25A fertilizer spreader gearbox receives rotational energy directly from the tractor's PTO shaft, typically operating at 540 RPM. Through its internally engineered bevel gear set (reducing stages 3-4), the unit converts this input speed using a 1:1.35 ratio, stepping up the output speed to deliver consistent, higher disc or auger RPM without overloading the driveline. The maximum input power of 8.1 kW is efficiently transformed to 9.9 kW output (13.5 HP), providing the torque necessary to drive spreading discs through heavy granule loads, damp conditions, or dense organic material. The conversion process is smooth and continuous, meaning the spreading discs maintain a consistent rotational speed regardless of modest variations in tractor engine load or ground speed. This consistent output is critical for achieving uniform fertilizer spreader gearbox<\/strong><\/a> ratio-dependent spreading widths and application rates required by modern precision agriculture.\r\n\r\nThe die-cast aluminium housing of this agricultural gearbox is both lightweight and structurally rigid, resisting deformation under the mechanical loads typical of field operation. High-quality oil seals around each shaft prevent ingress of dust, fertiliser granules, moisture, and plant material that could accelerate gear and bearing wear. The sealed oil-bath lubrication system ensures all internal components, including bevel gears, bearings, and output shafts, remain continuously lubricated even during extended operating hours. A 0.35 L oil reservoir using SAE 80W-90 gear oil maintains an effective lubricant film across all contact surfaces, minimising friction heat and wear debris. The housing's corrosion-resistant aluminium alloy performs reliably when exposed to ammonium nitrate, urea, potash, and liquid fertiliser splatter, environments that would rapidly degrade inferior gearbox materials.\r\n\r\nAlthough the L-25A operates as a direct-drive unit, it is designed for use within well-specified power limits (max 8.1 kW input) to prevent overload damage. In practice, the upstream PTO driveline incorporating slip clutches or shear bolt protection devices on the connecting PTO shaft interrupts torque if the spreading mechanism encounters a blockage, a large stone, or a sudden jamming event, shielding the fertilizer gearbox internals from catastrophic impact loads. The oil-bath lubrication system doubles as a thermal buffer, absorbing and dissipating heat generated during sustained spreading operations on long field passes. This combination of passive thermal management and upstream mechanical protection means the gearbox can reliably operate through full-day spreading sessions across large agricultural properties without risk of premature failure. Service intervals are straightforward: change oil after the first 50 to 70 hours and thereafter every 500 hours or annually, whichever occurs first, ensuring sustained reliable performance across many seasons of continuous agricultural use.\r\n\r\n\"Fertilizer\r\n

Applications of the L-25A Fertilizer Spreader Gearbox<\/h2>\r\n
\r\n

Pasture Management<\/h3>\r\nIn livestock operations, even fertiliser coverage across pastures is critical for maintaining consistent forage quality and grass density. The L-25A\u00a0agricultural gearbox for fertilizer spreader\u00a0use drives spreading discs at the right speed to achieve uniform distribution of urea, lime, and blended fertilisers, supporting healthy sward regeneration, improved carrying capacity, and better animal nutrition outcomes across grazing paddocks.\r\n

Orchards and Vineyards<\/h3>\r\nPrecision spreading around established fruit tree and vine root zones is critical to avoid fertiliser burn, soil acidification, or root damage from over-application. The L-25A\u00a0agricultural gearbox\u00a0powers inter-row fertiliser spreaders used in high-value permanent crop systems including apples, grapes, citrus, and stone fruits, where accurate placement of granular fertiliser within the root zone directly impacts fruit quality, colour development, and annual yield.\r\n

Crop Farming<\/h3>\r\nEssential for the uniform application of nitrogen, phosphorus, and potassium-based fertilisers across grain crops, vegetables, pulses, and fruit orchards. Precise spreading at the correct\u00a0fertilizer spreader gearbox ratio\u00a0ensures optimal nutrient uptake per hectare, maximising yields and reducing fertiliser input waste. Suitable for both pre-planting broadcast applications and in-season top dressing across all major staple crops.\r\n\r\n<\/div>\r\n
\r\n

Lawn and Turf Management<\/h3>\r\nGolf courses, sports stadiums, racecourses, and municipal parks require precision fertiliser delivery to maintain playing surface quality. The L-25A\u00a0fertiliser spreader gearbox\u00a0enables calibrated, low-rate spreading ideal for slow-release granular fertilisers used on fine turf. Its smooth speed output eliminates streaking or uneven application that can cause discolouration or turf inconsistencies on high-profile playing surfaces.\r\n\r\n<\/div>\r\n
\r\n

Horticulture and Nurseries<\/h3>\r\nGreenhouse operations and commercial nurseries require precise, small-area fertiliser distribution to potted plants and ornamental crop beds. The L-25A's reliable power output makes it effective for driving small-scale disc spreaders that apply controlled quantities of slow-release granular fertilisers, controlled-release pellets, or organic bio-stimulants to container crops and raised horticultural beds without over-application risk.\r\n\r\n<\/div>\r\n
\r\n

Landscaping and Garden Maintenance<\/h3>\r\nFor small-scale landscaping contractors and garden maintenance teams, the compact 4.1 kg L-25A\u00a0fertilizer gearbox\u00a0is easily integrated into compact tractor-mounted spreading attachments. It enables controlled, low-volume fertiliser delivery to flower beds, ornamental shrubs, and garden borders, where even minor over-application can scorch sensitive plants. Its light weight keeps small spreader machine designs manageable and manoeuvrable in confined residential and commercial garden settings.\r\n\r\n<\/div>\r\n
\r\n

Soil Amendments and Lime Spreading<\/h3>\r\nBeyond conventional fertilisers, this\u00a0fertilizer distributor gearbox is effective for distributing agricultural lime, gypsum, compost granules, and soil conditioners across paddocks requiring pH correction or structure improvement. Consistent disc speed through the L-25A ensures even coverage of these often heavier and denser materials, which require reliable torque delivery to prevent spreading disc stall or uneven throw patterns across different spreading widths.\r\n\r\n<\/div>\r\n\"Fertilizer\r\n

L-25A Fertiliser Spreader Gearbox Parts<\/h2>\r\n1. Gearbox Housing (Aluminium Shell)\r\nThe die-cast aluminium housing forms the structural skeleton of the entire fertilizer spreader gearbox assembly. Precision-machined to tight dimensional tolerances, it maintains accurate gear and bearing alignment under load. Its corrosion-resistant alloy composition resists the aggressive chemical environment of fertiliser application, while the lightweight construction (contributing to the total 4.1 kg unit weight) simplifies handling, installation, and machine mounting on a wide range of spreader frames.\r\n\r\n2. Input Shaft\r\nThe hardened steel input shaft (X-axis) accepts PTO drive from the tractor via a 1\" 3\/8 Z6 splined connection, transferring 540 RPM rotational energy into the gearbox at up to 8.1 kW. It is precision-ground for concentricity and supported by sealed rolling-element bearings at both ends, ensuring minimal runout and extended fatigue life under the cyclic torsional loads typical of PTO-driven fertilizer spreader gearbox parts applications.\r\n\r\n3. Bevel Gears\r\nThe precision-cut bevel gear pair achieves the 1:1.35 speed conversion ratio at the heart of this agricultural gearbox. Manufactured from case-hardened alloy steel with ground tooth profiles, these gears deliver efficient power transmission with minimal noise and heat generation. The bevel arrangement enables a 90-degree axis change between input and output shafts, a configuration essential for connecting horizontal PTO drive to vertically-mounted spinning disc assemblies on fertiliser spreaders.\r\n\r\n4. Output Shaft\r\nThe output shaft (Z-axis, 1\" 3\/8 Z6 or 25 mm diameter cylindrical, depending on configuration) delivers the stepped-up rotational speed directly to the spreader disc hub or intermediate drive connection. Manufactured from high-tensile steel with surface hardening, the output shaft is rated for the full 9.9 kW output at 540 RPM input. Its mounting compatibility matches original Comer L-25A dimensions, allowing direct-fit replacement without modification to existing disc drive assemblies.\r\n\r\n5. Bearings\r\nHeavy-duty tapered or deep-groove rolling element bearings support both the input and output shafts within the aluminium housing. Designed for radial and axial load capacity well beyond the L-25A's rated operating conditions, these bearings provide the precise shaft support necessary to maintain gear mesh alignment and prevent premature tooth wear. Pre-lubricated and sealed against moisture and fertiliser contamination, they require no independent maintenance beyond the standard gearbox oil change schedule.\r\n\r\n6. Oil Seals\r\nRadial lip seals fitted at each shaft exit point prevent internal SAE 80W-90 gear oil from leaking out and block the entry of external contaminants including water, fertiliser dust, and abrasive soil particles. The seals are manufactured from oil-resistant elastomer compounds specifically formulated for long-term compatibility with gear lubricants in agricultural conditions. Regular inspection of fertilizer spreader gearbox oil level and seal integrity is recommended during each major service interval to detect early wear.\r\n\r\n7. Oil Fill, Level, and Drain Plugs\r\nDedicated plugs on the gearbox housing allow easy oil filling to the 0.35 L capacity mark, level checking, and clean oil drainage during scheduled changes. Correct fertilizer spreader gearbox oil level maintenance is critical to gear and bearing longevity. The plugs are positioned for accessible service without removing the gearbox from the machine, reducing service time. Magnetic drain plugs trap metallic wear particles from the oil, serving as an early warning indicator of internal component wear when inspected at each oil change.\r\n\r\n\"L-25J\r\n

Common Troubleshooting<\/h2>\r\nGearbox Overheating During Operation\r\nExcessive heat build-up in the fertilizer gearbox is most commonly caused by insufficient oil level, incorrect oil viscosity, or an oil that has degraded beyond its service life. First, stop the machine and allow the unit to cool. Check the fertilizer spreader gearbox oil level through the level plug and top up to the correct mark with SAE 80W-90 if low. If oil is discoloured (dark brown or black) or contaminated with water, perform an immediate oil change. If overheating persists after correct oil fill, inspect the gear mesh for signs of abnormal wear or a damaged bearing.\r\n\r\nUnusual Noise or Vibration\r\nGrinding, clicking, or rumbling sounds from the agricultural gearbox during operation typically indicate bearing wear, gear tooth damage, or shaft misalignment with the PTO drive line. Immediately stop the spreader and disengage PTO. Inspect the PTO shaft connection for angular misalignment beyond the manufacturer's recommended operating angle. Check the gearbox mounting bolts for looseness. Remove the inspection cover and examine gears for chipped or pitted teeth. If internal damage is confirmed, replacement of affected bearings or gears from the fertilizer spreader gearbox parts catalogue is recommended before resuming work.\r\n\r\nOil Leakage Around Shaft Seals\r\nOil seeping from around the input or output shaft exit points indicates a worn or damaged radial lip seal. This is a common wear item on any fertiliser spreader gearbox operating in dusty or chemically harsh environments. Replace the relevant shaft seal using a seal driver tool appropriate to the shaft diameter. Clean all mating surfaces before fitting the new seal to ensure a proper seat. Overfilling the gearbox beyond the 0.35 L maximum capacity can also cause pressure build-up that pushes oil past otherwise healthy seals, so always verify correct fill volume after topping up.\r\n\r\nSpreader Disc Speed Inconsistency\r\nIf the spreading discs are running at variable or reduced speed compared to normal operation, the first check should be tractor PTO shaft engagement and the condition of the connecting PTO driveshaft universal joints, which can seize or wear if lubrication is neglected. Internally, check that the fertilizer spreader gearbox ratio is producing the expected output speed by measuring output shaft RPM with a tachometer. Low output speed at correct PTO input speed may indicate worn bevel gear teeth, which require gear set replacement to restore normal performance.\r\n\r\nDifficult or Stiff PTO Shaft Engagement\r\nResistance when connecting the PTO shaft to the L-25A input can indicate corrosion buildup on the 1\" 3\/8 Z6 splined input shaft, foreign material lodged in the spline, or a deformed PTO coupling yoke. Clean the input shaft splines thoroughly with a wire brush and apply a light coat of anti-seize grease or corrosion inhibitor to prevent future seizure. Inspect the PTO shaft yoke bore for wear or deformation that may have resulted from repeated engagement at incorrect alignment angles, which can also accelerate input shaft bearing wear over time.\r\n\r\nMounting Looseness or Vibration at Spreader Frame\r\nPhysical looseness of the gearbox on its mounting frame leads to driveline vibration, accelerated bearing wear, and eventual gear misalignment. Inspect all four mounting flange bolts (M10 or equivalent to match the 11 mm hole pattern) for correct torque specification. Thread-locking compound applied to mounting bolts is advisable in high-vibration applications. If the mounting flange face shows signs of fretting corrosion or surface damage from prolonged loose mounting, clean and treat the contact surfaces before re-torquing to prevent recurrence of the looseness issue.\r\n\r\nPremature Gear or Bearing Failure\r\nEarly gear or bearing failure in a fertilizer spreader gearbox that has not reached its expected service life is almost always traceable to one of three root causes: operating at input powers exceeding the 8.1 kW maximum rating, running with insufficient or degraded oil, or sustained operation with PTO shaft misalignment beyond acceptable angles. Review the machine's operating conditions against the rated specifications. Confirm that the oil has been changed at the prescribed 50 to 70 hour initial interval and that SAE 80W-90 viscosity grade oil is being used, not a lighter automotive oil which lacks the load-carrying film strength required for gear lubrication.\r\n\r\nFertiliser Contamination of Gearbox Oil\r\nWater-mixed fertiliser solutions or hygroscopic granular materials can draw moisture into the gearbox if seals are compromised, leading to oil emulsification and loss of lubricating film strength. Milky or grey-coloured oil at the drain is a clear indicator of water contamination. Drain and flush the gearbox, replace the contaminated oil with fresh SAE 80W-90, and identify the moisture ingress point, typically a worn shaft seal or a cracked housing. Timely attention prevents corrosive damage to polished gear tooth surfaces and bearing raceways.\r\n\r\n\"Fertilizer\r\n

Correct Maintenance of the L-25A Fertilizer Spreader Gearbox<\/h2>\r\n
\r\n

Step 1: Initial Oil Fill Before First Use<\/h3>\r\nThe L-25A\u00a0fertilizer spreader gearbox\u00a0is supplied dry, without oil. Before the first operation, fill through the top fill plug with the correct SAE 80W-90 gear oil to the level plug mark (maximum 0.35 L). Use only the specified viscosity grade to ensure the oil film is adequate for the gear mesh contact pressures at 540 RPM input. Using incorrect oil viscosity is the leading cause of premature gear tooth surface fatigue in agricultural gearbox applications.\r\n\r\n<\/div>\r\n
\r\n

Step 2: First Oil Change at 50 to 70 Hours<\/h3>\r\nAfter the initial 50 to 70 operating hours, perform the first oil change. During break-in, small metallic wear particles from the bedding-in of gear tooth surfaces accumulate in the oil. Draining and replacing the oil at this interval removes these particles before they can act as abrasive cutting agents, significantly extending internal component life. Warm the gearbox slightly before draining to improve oil flow and particle suspension. Refill to the level plug mark with fresh SAE 80W-90.\r\n\r\n<\/div>\r\n
\r\n

Step 3: Regular Oil Changes Every 500 Hours or Annually<\/h3>\r\nAfter the initial change, replace the SAE 80W-90 gear oil every 500 operating hours or at least once per year, whichever comes first. This ensures lubricant additive packages for corrosion protection and extreme-pressure resistance remain effective. At each oil change, inspect the drained oil colour and clarity. Dark brown or grey oil indicates oxidation or water contamination, requiring investigation of seal integrity before the next spreading season. The 500-hour interval aligns conveniently with annual seasonal service schedules for most farming operations.\r\n\r\n<\/div>\r\n
\r\n

Step 4: Inspect and Clean External Housing<\/h3>\r\nAfter each spreading session, clean fertiliser residue, chemical deposits, and mud from the external surfaces of the aluminium housing. Concentrated fertiliser salts, particularly ammonium nitrate or urea-based products, are corrosive to aluminium if allowed to dry on the surface over extended periods. A low-pressure water rinse followed by drying is sufficient for routine cleaning. Inspect mounting bolts, shaft seal areas, and the housing surface for cracks, corrosion pitting, or mechanical damage that could compromise structural integrity or oil containment during the next operation.\r\n\r\n<\/div>\r\n
\r\n

Step 5: Check Shaft Seal Condition<\/h3>\r\nInspect input and output shaft lip seals for oil weeping, cracking, or hardening at each seasonal service. A thin film of oil on the outside of the shaft near the seal exit point is an early warning sign that seal replacement is needed within the next operating period. Replace seals proactively at the first sign of degradation, as a failed seal allows both oil loss and contaminant ingress. When replacing seals, always use a proper seal driver sized to the specific shaft diameter to avoid cocking or distorting the new seal lip during installation.\r\n\r\n<\/div>\r\n

Step 6: Lubricate PTO Shaft and Check Alignment<\/h3>\r\nThe connecting PTO drive shaft, its universal joints, and slip clutch (where fitted) require their own lubrication schedule independent of the gearbox. Grease all universal joint nipples with a lithium-based EP grease at the interval specified by the PTO shaft manufacturer. Also verify PTO shaft operating angle does not exceed the U-joint manufacturer's rated maximum angle under working conditions, as excessive angle dramatically shortens joint life and introduces vibration impulses that stress the\u00a0fertilizer gearbox input shaft bearings and housing mountings.\r\n\r\n<\/div>\r\n\"Fertilizer\r\n

Fertilizer Spreader Gearbox and PTO Drive Shaft<\/h2>\r\nThe fertilizer spreader gearbox is the critical mechanical interface between the tractor's Power Take-Off and the spreading mechanism of the fertiliser distribution machine. It receives raw rotational power from the tractor PTO, which typically operates at a standardised 540 RPM shaft speed, and converts this into the speed and torque output most appropriate for driving the spreading disc assembly. In the case of the L-25A, the 1:1.35 ratio steps the input speed up slightly to deliver faster disc rotation that improves granule throw distance and spreading pattern width, while maintaining tractable torque levels. The gearbox also performs a critical geometric function, changing the angle of power transmission from the horizontal PTO shaft axis to the vertical or angled disc drive axis using its internal bevel gear set, a function that would otherwise require a complex and unreliable chain or belt transmission arrangement. Fertilizer spreader gearboxes from reputable manufacturers like CMN Transmission are engineered to perform this power routing reliably for thousands of operating hours under the demanding and chemically hostile conditions of agricultural fertiliser application.\r\n\r\nThe PTO shaft is the mechanical driveshaft that physically connects the tractor's rotating PTO output stub to the input shaft of the fertilizer distributor gearbox. Most modern PTO shafts used with fertiliser spreading equipment are telescoping assemblies incorporating two or more universal joints (U-joints) that accommodate the angular and length changes that occur as the spreader moves over uneven ground or turns in the field. The L-25A gearbox accepts standard 1\" 3\/8 Z6 (six-spline) PTO shaft connections, which is the most common standardised tractor PTO interface in the 540 RPM category globally, ensuring broad compatibility across tractor makes and models from all major agricultural regions.\r\n\r\nIn operation, the tractor operator engages the PTO lever, which connects the tractor's transmission to the PTO output shaft at a specified speed (540 or 1000 RPM). The rotating PTO stub drives the connected PTO driveshaft, which transmits this rotation through its universal joints to the input shaft of the L-25A agricultural gearbox. The gearbox receives this rotation at up to 8.1 kW, converts it through the 1:1.35 bevel gear set, and delivers the stepped-up speed and torque output to the spreader disc or auger shaft. The disc then rotates at the higher output speed and throws granular fertiliser, lime, or seed outward in a controlled spreading pattern determined by disc shape, vane configuration, and exit speed. The entire system operates as a continuous mechanical power train, with the efficiency of each link, tractor PTO engagement, PTO driveshaft, and gearbox, directly affecting the consistency and quality of the spreading pattern achieved across the field.\r\n\r\nSelecting the right PTO shaft to pair with the L-25A fertilizer spreader gearbox for sale is as important as the gearbox selection itself. The PTO shaft must be rated for at least the maximum power transmitted (8.1 kW at 540 RPM), with an appropriate safety factor for shock loads at PTO engagement. Length must be checked against the tractor-to-spreader distance at both minimum and maximum hitch extension, to ensure the shaft never bottoms out its telescopic tube or over-extends and separates. PTO shafts should incorporate a slip clutch or shear bolt protection device between the shaft and the gearbox input to interrupt torque if the spreading mechanism jams, protecting both the gearbox internals and the tractor PTO clutch from overload damage.\r\n\r\n\r\n\r\n

Frequently Asked Questions<\/h2>\r\nQ1: Is the CMN L-25A a direct replacement for the Comer L-25A gearbox?<\/strong>\r\nA: Yes. The CMN Transmission L-25A fertilizer spreader gearbox is engineered as a direct OEM-equivalent replacement for the Comer L-25A unit. All critical dimensions including the mounting flange bolt hole pattern (N.4 x diameter 11 mm), shaft diameters, and shaft lengths are matched to the original Comer specification. No machine frame modification, adaptor plates, or shaft machining is required for a standard direct swap installation.\r\n\r\nQ2: What oil should I use in the L-25A fertilizer spreader gearbox?<\/strong>\r\nA: The L-25A requires SAE 80W-90 gear oil with a maximum fill capacity of 0.35 litres. Use a mineral or synthetic EP (Extreme Pressure) gear oil meeting GL-4 or GL-5 specifications. Do not use engine oil, hydraulic oil, or grease as a substitute. Using the correct viscosity grade is critical for maintaining the protective lubricant film between bevel gear tooth surfaces at 540 RPM input speed. If operating in extreme low-temperature environments, consult CMN Transmission for alternative viscosity recommendations.\r\n\r\nQ3: What is the correct fertilizer spreader gearbox oil level check procedure?<\/strong>\r\nA: To check the fertilizer spreader gearbox oil level, ensure the machine is parked on level ground and the gearbox has cooled from operating temperature. Remove the oil level plug (located on the side of the housing) and check that oil is present up to the bottom of the level plug hole thread. If oil does not reach the level plug, add SAE 80W-90 through the top fill plug until oil begins to weep from the level plug hole, then refit both plugs securely. Never overfill beyond the level plug as excess oil creates internal pressure that can blow out shaft seals.\r\n\r\nQ4: What fertilizer spreader gearbox ratio does the L-25A have, and what does it mean for spreading?<\/strong>\r\nA: The L-25A has a 1:1.35 fertilizer spreader gearbox ratio. This is a speed-increasing ratio, meaning for every one revolution of the input shaft, the output shaft turns 1.35 times. At standard 540 RPM PTO input, the output shaft turns at approximately 729 RPM. This faster output speed drives spreading discs at a higher rotational velocity, increasing the centrifugal throw force on the fertiliser particles and achieving greater spreading width compared to a 1:1 direct drive gearbox, without requiring a higher tractor PTO speed.\r\n\r\nQ5: Can the L-25A handle liquid fertilizers as well as granular products?<\/strong>\r\nA: The L-25A agricultural gearbox is designed to drive the mechanical spreading mechanism, not to contact the fertiliser product directly. Its aluminium housing and sealed shaft design resist external exposure to fertiliser splatter from both granular and liquid product applications. For liquid fertiliser spreading systems using disc or boom spreaders, the gearbox performs the same power transmission function as in granular spreading. Ensure the external housing and seals are rinsed after liquid fertiliser sessions to prevent extended chemical contact with the housing surfaces.\r\n\r\nQ6: How long does the L-25A fertilizer spreader gearbox last under normal farm use?<\/strong>\r\nA: Under normal agricultural operating conditions with the prescribed oil changes (initial at 50 to 70 hours, then every 500 hours or annually), the L-25A fertilizer distributor gearbox is designed for a service life of several thousand operating hours. Actual longevity depends on operating within rated power limits, maintaining correct PTO shaft alignment, using the specified SAE 80W-90 oil, and adhering to the maintenance schedule. Operators who follow the recommended service routine consistently report gearboxes running well beyond 1,000 hours before requiring internal component attention.\r\n\r\nQ7: What shaft configurations are available for the L-25A?<\/strong>\r\nA: The L-25A family, as detailed in the Comer catalogue and matched by CMN Transmission, is available in multiple shaft configurations. The input shaft (X) accepts a 1\" 3\/8 Z6 six-spline PTO connection or a 25 mm cylindrical shaft depending on configuration. Output shafts (Y and Z positions) are available in 1\" 3\/8 Z6 spline, 22 mm, or 25 mm cylindrical formats at various lengths, allowing adaptation to different spreader disc hub interfaces. Contact CMN Transmission to confirm the exact shaft configuration required for your specific spreader model before ordering.\r\n\r\nQ8: Is a PTO shaft included with the L-25A gearbox purchase?<\/strong>\r\nA: No, the L-25A fertilizer gearbox is supplied as a standalone unit without a PTO driveshaft. The connecting PTO shaft must be selected separately based on the tractor-to-machine distance and power requirements. CMN Transmission can advise on compatible PTO shaft specifications on request. When selecting a PTO shaft for use with the L-25A, ensure it is rated for at least the maximum 8.1 kW input power and incorporates a slip clutch or shear bolt overload protection device for safe operation.\r\n\r\nQ9: Where can I buy the L-25A fertilizer spreader gearbox and what is the lead time?<\/strong>\r\nA: The L-25A fertilizer spreader gearbox for sale is available to order directly from CMN Transmission through this product page, or via our authorised distributor network in the United States, Canada, Europe, Australia, and other major agricultural markets. Standard lead time for in-stock units is 1 to 3 business days for domestic orders, with international shipping times varying by destination. Contact our sales team for express shipping options or bulk order pricing for dealer and OEM customers.\r\n\r\nQ10: What certifications does CMN Transmission hold for the L-25A gearbox?<\/strong>\r\nA: CMN Transmission holds CE marking (confirming conformity with European safety standards), ISO 9001 quality management system certification, Environmental Management certification, and Occupational Health and Safety certification. These accreditations demonstrate that the L-25A fertiliser spreader gearbox is manufactured under a verified and audited quality management system, providing customers with confidence in product consistency, dimensional accuracy, and material traceability across all production batches.\r\n\r\n\"L-25A\r\n

Customer Reviews<\/h2>\r\nJames, Corn and Soybeans, United States<\/strong>\r\n\"We run a mixed arable operation here in Iowa and had our original Comer box fail right at the start of the spring spreading season. CMN Transmission had the L-25A in stock and it shipped within 48 hours. Dropped straight in without a single modification needed. Been running it for two seasons now and it handles urea and MAP without any issues at all. Build quality feels solid compared to what we had before. Very happy with the purchase.\"\r\n\r\nMichael, Crop Farming, Canada<\/strong>\r\n\"I ordered two units of the L-25A gearbox for our spreader setup on the farm in Saskatchewan. The 1:1.35 ratio is exactly what our spreader needed. Delivery came to Calgary in about 12 days which was actually faster than I expected. One thing I really appreciated was the technical support team answering my questions about oil fill before commissioning. No issues so far after one full spring and one fall season. Would order no question again.\"\r\n\r\nCarlos, Soybean and Cotton, Brazil<\/strong>\r\n\"We work with fertilizer spreaders on our farm in Mato Grosso and needed a reliable replacement for our Comer L-25A. CMN Transmission delivered quickly and the product fit perfectly. We have already used it for about 300 hours distributing urea and potassium without any leaks or overheating. The light weight of 4.1 kg makes maintenance in the field much easier. I only deducted one star because the promised delivery time was delayed a bit. Overall great product.\"\r\n\r\nLuis, Wheat and Soybeans, Argentina<\/strong>\r\n\"We have been using this gearbox on our fertilizer spreaders in Cordoba for the last three agricultural cycles. The 1:1.35 ratio gives us exactly the application width we are looking for with wheat and soybeans. The aluminum housing has held up well even with mixed liquid fertilizers. The first time we used it we changed the oil at 60 hours as indicated by the instructions and since then the gear has worked perfectly. Very good product, we recommend it.\"\r\n\r\nDavid, Crop Farming, United Kingdom<\/strong>\r\n\"We run a contract spreading operation in North Yorkshire and needed a reliable replacement gearbox mid-season. CMN Transmission dispatched the L-25A within 24 hours and it arrived next morning. Fitted it on the spreader trailer same day and we were back in the field by afternoon. The quality of the aluminium housing and internal gears looks as good as any OEM unit I've used. Five months on and there's no issues at all. Good value, brilliant service, and an excellent product for the price point.\"\r\n\r\nPierre, Crop Farming, France<\/strong>\r\n\"We have been using this gearbox on our spreaders in Beauce for two seasons now. The 1:1.35 ratio is perfectly suited for our fertilizer spreaders. The manufacturing quality is excellent and the aluminum casing is well protected against corrosive fertilizers. We ordered three units in total and all of them are working without any problems. The technical support at CMN Transmission is very responsive; they answered all our questions quickly. Very good product.\"\r\n\r\nKlaus, Agricultural Equipment, Germany<\/strong>\r\n\"As a dealer for agricultural equipment parts in Bayern, I've sourced these L-25A gearboxes from CMN Transmission for several of our customers. The fitment accuracy compared to original Comer units is spot on, our customers have all reported trouble-free installation. The consistent quality across the batches we have received and the competitive pricing has made this our go-to recommendation for Comer L-25A replacement. CMN Transmission's documentation is also well done, which helps our customers with first-time service.\"\r\n\r\nAndrew, Agricultural Equipment, Australia<\/strong>\r\n\"We supply and service fertilizer spreading machinery in Victoria and New South Wales and CMN Transmission is now our preferred source for L-25A replacement gearboxes. The unit quality is consistent, delivery to Australia is reasonable, and the gearbox handles the conditions here well, including the heat and the abrasive fertiliser blends used for broad-acre spreading. Had one customer run his L-25A for over 800 hours before a scheduled service and the gearbox internals looked excellent on inspection. Really impressed with the longevity.\"\r\n\r\nRoberto, Agricultural Machinery, Mexico<\/strong>\r\n\"We are an agricultural machinery service company in central Mexico and we have installed several of these gearboxes in our clients' fertilizer spreaders. The 1:1.35 transmission ratio works well with the discs of the European equipment we have in our area. The quality is good and the price is very competitive compared to the original spare parts. We deducted one star because sometimes the international shipping time is a bit long, but the product itself is excellent.\"","_et_gb_content_width":""},"product_brand":[],"product_cat":[309],"product_tag":[316,315,311,317,318,319,310],"class_list":{"0":"post-8104","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-fertilizer-spreader-gearbox","7":"product_tag-fertiliser-spreader-gearbox","8":"product_tag-fertilizer-distributor-gearbox","9":"product_tag-fertilizer-spreader-gearbox","10":"product_tag-fertilizer-spreader-gearbox-for-sale","11":"product_tag-fertilizer-spreader-gearbox-manufacturers","12":"product_tag-fertilizer-spreader-gearbox-suppliers","13":"product_tag-gearbox-for-fertilizer-spreader","15":"first","16":"instock","17":"shipping-taxable","18":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product\/8104","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/comments?post=8104"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/media\/8004"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/media?parent=8104"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product_brand?post=8104"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product_cat?post=8104"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product_tag?post=8104"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
