Enhanced Precision Distribution<br \/>\nThe fixed 1:2.78 ratio ensures repeatable, calibrated rotational output at every PTO cycle, enabling uniform fertilizer distribution across the spread width. Consistent output speed eliminates hot spots and skip zones, directly reducing over-application. Over a full season, precision spreading translates to measurable savings on input costs while protecting soil health from nutrient imbalance.<\/p>\n<p>2. Industrial-Grade Durability<br \/>\nThe aluminium housing resists corrosion from fertilizer chemicals, moisture, and field debris without the weight penalty of cast iron. Internal components are precision-machined from hardened steel, with oil seals and sealed bearings that block dust and water ingress. This fertilizer spreader gearbox is built to endure thousands of operating hours across multiple growing seasons in the harshest field conditions.<\/p>\n<p>3. Optimized Fuel Efficiency<br \/>\nNauwkeurige tandwieloverbrenging en smering met een oliebad minimaliseren interne wrijvingsverliezen, waardoor vrijwel al het aftakasvermogen van de tractor het strooimechanisme bereikt. Het resultaat is een lagere motorbelasting bij gelijke strooisnelheden. Boeren met grote percelen melden meetbare besparingen op het brandstofverbruik per hectare in vergelijking met versleten of slecht afgestemde landbouwversnellingsbakken, wat de economische haalbaarheid van elke strooibeurt verbetert.<\/p>\n<p>4. Brede toepassingsmogelijkheden<br \/>\nDeze landbouwversnellingsbak voor kunstmeststrooiers is compatibel met korrelige NPK-mengsels, ureumkorrels, kalkkorrels, organische compost en diverse zaadstrooierconfiguraties, en past zich aan uiteenlopende materiaalsoorten en terreinprofielen aan. De standaard 1-3\/8\u2033 zes-spline aftakas-aansluiting en 22 mm uitgaande as accepteren een breed scala aan strooischijfassemblages, waardoor het een echte alles-in-\u00e9\u00e9n oplossing is voor gemengde gewassenbedrijven en gediversifieerde bedrijven.<\/p>\n<p>5. Weinig onderhoud nodig<br \/>\nThe oil-bath lubrication system bathes all gears and bearings in a continuous film of 80W-90 gear oil, eliminating grease nipple schedules and reducing service visits. With the first oil change required only at 50-70 hours and subsequent intervals at 500 hours or annually, maintenance demands are minimal. Modular design means individual fertilizer spreader gearbox parts such as seals and bearings are readily replaceable without full gearbox removal.<\/p>\n<p>6. Direct Comer L-25A Compatibility<br \/>\nEngineered as a bolt-on replacement for the original Comer L-25A gearbox, this unit matches OEM mounting dimensions, shaft diameters, and spline counts precisely. Operators can swap in the CMN Transmission L-25A without modifying spreader frames, PTO drivelines, or disc mounts. This compatibility cuts machine downtime during the critical spreading season, making it the preferred choice for fleet managers seeking cost-effective, reliable spares from trusted <a href=\"https:\/\/korea-transmission.com\/nl\/fertilizer-spreader-gearbox\/\"><strong>versnellingsbak van kunstmeststrooier<\/strong><\/a> manufacturers.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8006 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1-2.78.webp\" alt=\"L-25A Kunstmeststrooier Versnellingsbak 1-2.78\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1-2.78.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1-2.78-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Werkingsprincipe<\/h2>\n<p>De krachtoverbrenging begint bij de aftakas van de tractor, die met de standaard 540 toeren per minuut draait. De aftakas is via een 1-3\/8\u2033 zes-spline koppeling verbonden met de ingaande as van de versnellingsbak, waardoor de twee assen stevig met elkaar verbonden zijn. Deze standaard interface garandeert compatibiliteit met een breed scala aan tractormerken en -modellen. Zodra de tractor de aftakas inschakelt, stroomt de rotatie-energie continu via de koppeling naar de ingaande as van de L-25A versnellingsbak, waarmee het gehele krachtoverbrengingsproces start. De ingaande as wordt ondersteund door precisielagers die zowel radiale als axiale belastingen opvangen die tijdens het gebruik op het veld ontstaan.<\/p>\n<p>Once inside the housing, input torque passes through a matched pair of precision-cut bevel gears at the heart of this fertilizer distributor gearbox. The 1:2.78 gear ratio increases rotational speed from the 540 RPM tractor PTO to an output of approximately 1,501 RPM, which is ideal for driving centrifugal spreading discs at the speed needed for accurate lateral distribution of granular or pelleted fertilizers. Bevel gear geometry also changes the torque direction by 90 degrees in some configurations, allowing the output shaft to be oriented perpendicular to the input. The gear mesh is optimized for quiet, low-vibration operation even at maximum load.<\/p>\n<p>The output shaft, measuring 22 mm in outside diameter, transmits up to 31 N\u00b7m of torque directly to the spinner disc assembly or agitator mechanism mounted on the spreader frame. This torque level is engineered specifically for the resistance forces encountered when accelerating fertilizer granules from the disc surface at the spreading speed required for uniform lateral distribution across swath widths of several meters. The output shaft is supported by a heavy-duty sealed bearing that withstands both the continuous rotational load and the intermittent shock loads caused by uneven fertilizer flow or material bridging in the hopper. Stable output speed ensures repeatable spreading patterns run after run.<\/p>\n<p>The aluminium housing is partially filled with 80W-90 gear oil to a maximum capacity of 0.35 litres. As the gears rotate, they carry a continuous film of oil across all contact surfaces, reducing friction, dissipating heat, and extending component life far beyond what grease-packed alternatives can achieve. The oil-bath system requires no external pump and operates silently under all load conditions. The correct fertilizer spreader gearbox oil level should be verified before each spreading season and after the first 50-70 hours of operation. Subsequent oil changes at 500-hour or annual intervals keep the lubrication film in peak condition and prevent accelerated gear and bearing wear caused by degraded lubricants.<\/p>\n<p>High-quality lip seals fitted to both input and output shaft bores prevent fertilizer dust, field debris, and moisture from entering the gearbox interior. Fertilizer chemicals, particularly nitrogen-based compounds and lime, are highly corrosive when in contact with unprotected metal surfaces. The dual-lip seal design maintains positive exclusion of contamination even during prolonged operation in dusty conditions or when the spreader is washed down with high-pressure water. The aluminium housing itself provides inherent corrosion resistance, and an epoxy-coated finish further protects external surfaces. Together, these measures ensure the gearbox interior remains clean, dry, and properly lubricated throughout its service life.<\/p>\n<p>In field conditions, foreign objects, hopper blockages, or disc jamming can cause sudden torque spikes that would otherwise damage internal gears or the tractor driveline. The L-25A gearbox is designed to operate within its rated 5.2 kW \/ 31 N\u00b7m envelope, and is typically paired with an upstream PTO shaft fitted with a slip clutch or shear bolt safety device. When torque exceeds the preset limit, the slip clutch disengages momentarily, preventing the overload impulse from reaching the gearbox. This protective pairing between the fertilizer spreader gearbox and the PTO safety device safeguards the most expensive drivetrain components and minimizes costly downtime during peak-season spreading operations.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8093 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2.webp\" alt=\"Toepassingen van de versnellingsbak van een kunstmeststrooier\" width=\"1200\" height=\"900\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2-980x735.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2-480x360.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Toepassingen van de versnellingsbak van de kunstmeststrooier<\/h2>\n<div>\n<h3>Broadacre Crop Farming<\/h3>\n<p>Essential for the uniform application of granular NPK fertilizers across large cereal, oilseed, and pulse crops.

Safety Preparation and Machine Isolation<br \/>\nBefore beginning any gearbox removal work, disengage the tractor PTO and shut down the tractor engine completely. Apply the parking brake, remove the ignition key, and wait for all rotating components to come to a full stop. Place wheel chocks under tractor wheels and spreader axle. Disconnect the PTO driveshaft from both the tractor output and the gearbox input. This full isolation procedure prevents accidental PTO engagement during the removal process, which could cause severe injury.<\/p>\n<p>2. Tap de oude versnellingsbakolie af.<br \/>\nPosition a suitable drain pan beneath the old gearbox. Remove the oil drain plug (typically at the lowest point of the housing) and allow all gear oil to drain completely. Proper oil disposal in accordance with local environmental regulations is required. Draining before removal prevents spillage on the spreader frame and into the soil. Note the condition and color of the drained oil, as excessive contamination or metal particles indicate internal wear that may have contributed to gearbox failure.<\/p>\n<p>3. Remove the Spreading Disc or Output Coupling<br \/>\nUsing appropriate spanners, remove the retaining nut or bolt securing the spreading disc, vane assembly, or output coupling to the gearbox output shaft. Mark the disc position relative to the shaft before removal if a keyway or splined connection is used, to ensure correct angular alignment during reinstallation. Set the disc and all fasteners aside in a clean location. Inspect the output shaft bore for signs of fretting, corrosion, or wear caused by a loose disc connection on the previous unit.<\/p>\n<p>4. Draai de bouten los en verwijder de oude versnellingsbak.<br \/>\nSupport the old gearbox weight manually or with a suitable support stand before removing the mounting flange bolts. Undo each mounting bolt in a diagonal sequence to release clamping load evenly. Once all bolts are removed, slide the gearbox forward to disengage it from any locating dowels or the spreader frame boss. Clean the mounting face on the spreader frame thoroughly with a wire brush and rag, removing all traces of old gasket material, rust, and fertilizer residue before fitting the replacement unit.<\/p>\n<p>5. Inspect PTO Driveline Components<br \/>\nBefore installing the new L-25A gearbox, inspect the PTO driveshaft, safety shield, slip clutch, and cross-joint assembly for wear or damage. Replace any worn universal joints, cracked guards, or slipping clutch discs. Installing a new gearbox onto a worn driveline transfers vibration and shock loads into the new unit, accelerating bearing and gear wear. This inspection step is especially important if the previous gearbox failed due to overload, as the PTO driveline is often damaged in the same event.<\/p>\n<p>6. Install and Torque the New L-25A Gearbox<br \/>\nPosition the new CMN Transmission L-25A gearbox onto the clean spreader frame mounting face, aligning the flange holes and any locating dowels. Apply a thin film of anti-seize compound to the mounting bolt threads to prevent future corrosion-induced seizure. Insert all mounting bolts and tighten them in a diagonal sequence to the manufacturer-specified torque (typically 25-35 N\u00b7m for M8 grade 8.8 fasteners). Do not over-torque, as this can distort the aluminium flange and cause misalignment of the internal gear mesh.<\/p>\n<p>7. Fill with Fresh 80W-90 Gear Oil<br \/>\nRemove the oil fill plug and pour SAE 80W-90 gear oil into the gearbox to the correct level, not exceeding the 0.35-litre maximum capacity. Use the oil level check plug to confirm the correct fertilizer spreader gearbox oil level before reinstalling the fill plug. Correct fill level is critical: overfilling causes seal blowout and leaks, while underfilling starves bearings and gears of lubrication, leading to rapid wear. Replace the fill plug and tighten firmly, then wipe away any spilled oil from the housing exterior.<\/p>\n<p>8. Reconnect PTO and Run-In Check<br \/>\nReattach the spreading disc and PTO driveshaft. Reconnect the PTO driveline, ensuring the safety shield is correctly positioned and secured. Start the tractor and engage PTO at idle speed (low RPM) for a 5-minute unloaded run-in period. Listen for abnormal noise and check for oil leaks at all seal points. After the run-in, shut down the tractor and re-inspect all mounting bolts for tightness. The first oil change should be scheduled at 50-70 operating hours to flush any assembly debris from the new gearbox before returning to normal service intervals.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8036 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-1.9.webp\" alt=\"L-25J kunstmeststrooier versnellingsbak 1-1.9\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-1.9.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-1.9-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Common Troubleshooting for the L-25A Fertilizer Spreader Gearbox<\/h2>\n<div>\n<h3>Excessive Noise or Whining<\/h3>\n<p>Abnormal noise from the gearbox during PTO operation typically indicates insufficient oil level, degraded lubricant, incorrect oil grade, or worn bearings and gears. First, shut down the PTO immediately and check the\u00a0fertilizer spreader gearbox oil level. If the oil level is correct, drain and refill with fresh 80W-90 gear oil. If noise persists after oil service, the gearbox should be removed for internal inspection, as continued operation with worn gears or dry bearings will cause rapid and irreversible internal damage.<\/p>\n<\/div>\n<div>\n<h3>Oil Leaks Around Shaft Seals<\/h3>\n<p>Oil seepage at the input or output shaft bores indicates worn or damaged lip seals. Seal deterioration is accelerated by heat cycles, chemical exposure from fertilizer residue, or operation with the wrong oil viscosity. Replace both shaft seals as a pair whenever one is found to be leaking, as both will have experienced identical service conditions. Overfilling the gearbox beyond the 0.35-litre maximum can also cause seal bypass; always verify the correct fill level after any oil service on these\u00a0fertilizer spreader gearbox parts.<\/p>\n<\/div>\n<div>\n<h3>Vibration at the Spreader Disc<\/h3>\n<p>Excessive vibration transmitted from the gearbox to the spreading disc assembly often originates from a loose or worn output shaft coupling, a bent disc, or worn output shaft bearings. Shut down the PTO and manually check the disc for radial play on the output shaft. A loose disc retaining nut is the most common cause and requires only re-torqueing to specification. If bearing play is detected at the output shaft, the gearbox requires bearing replacement. Operating with significant vibration will rapidly accelerate wear across all internal\u00a0fertilizer spreader gearbox parts.<\/p>\n<\/div>\n<div>\n<h3>Oververhitting van de versnellingsbak<\/h3>\n<p>A gearbox housing that becomes unusually hot to the touch during normal operation indicates lubrication failure, an overloaded condition, or incorrect oil viscosity. Immediately shut down the PTO and allow the unit to cool before investigating. Check the oil level and condition first. If the oil is correct but the unit overheats at rated load, the gearbox may be operating beyond its 5.2 kW \/ 7 HP power limit. Contact CMN Transmission to discuss whether a higher-rated\u00a0agricultural gearbox for fertilizer spreader\u00a0is required for your application.<\/p>\n<\/div>\n<div>\n<h3>Irregular or Uneven Spreading Pattern<\/h3>\n<p>Als de kunstmeststrooier ondanks correcte machine-instellingen een ongelijkmatige zijdelingse verdeling produceert, kan de oorzaak een inconsistente rotatiesnelheid van de schijven zijn. Dit kan worden veroorzaakt door interne beschadiging van de tandwielen of versleten lagers die snelheidsvariatie in de versnellingsbak veroorzaken. Ook versleten schijfbladen, verstopte bladenkanalen of een onjuiste overbrengingsverhouding van de versnellingsbak voor de vereiste strooisnelheid kunnen de oorzaak zijn. Controleer of het model en de overbrengingsverhouding van de versnellingsbak overeenkomen met de ontwerpvereisten van uw strooier en inspecteer de schijfbladen op slijtage of ophoping van kunstmest voordat u de versnellingsbak afkeurt.<\/p>\n<\/div>\n<div>\n<h3>PTO Slip or Input Shaft Wear<\/h3>\n<p>Slippen of haperen van de krachtoverbrenging bij het aftakas-aansluitpunt wordt meestal veroorzaakt door versleten spiebanen van 1-3\/8 inch op de ingaande as van de versnellingsbak of de aftakas-aandrijflijn. Slijtage van de spiebanen is progressief en wordt doorgaans veroorzaakt door onvoldoende overlap van de aftakas, een te grote hoek van de aftakas of schokbelastingen door overbelasting. Controleer de ingaande spiebaan door de aftakas te verwijderen en te controleren op afgeronde of afgebroken spiebanen. Het vervangen van alleen de versnellingsbak wanneer ook de spiebanen van de aftakas-aandrijflijn versleten zijn, zal ertoe leiden dat de ingaande as van de nieuwe versnellingsbak binnen korte tijd opnieuw defect raakt.<\/p>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8092 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1.webp\" alt=\"Toepassingen van de versnellingsbak van een kunstmeststrooier\" width=\"1200\" height=\"900\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1-980x735.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1-480x360.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Versnellingsbak en aftakas van de kunstmeststrooier<\/h2>\n<p>De relatie tussen de versnellingsbak van de kunstmeststrooier en de aftakas is de bepalende mechanische interface van elk door een tractor aangedreven strooisysteem. De aftakas (PTO-as) is het kanaal waardoor de tractormotor rotatie-energie overbrengt op de strooier. De aftakas, die bij landbouwtractoren doorgaans met 540 toeren per minuut draait, is via een spiebaankoppeling verbonden met de ingang van de versnellingsbak. Deze koppeling moet qua profiel, diameter en aantal spiebanen overeenkomen voor een veilige en spelingvrije krachtoverbrenging. In het geval van de L-25A is de ingang geschikt voor een 1-3\/8\u2033 zes-spiebaan as conform ISO 500-normen, waardoor deze compatibel is met de overgrote meerderheid van compacte tot middelgrote landbouwtractoren die wereldwijd worden gebruikt.<\/p>\n<p>De aftakasconstructie zelf bestaat uit een binnen- en een buitenbuis die in elkaar schuiven om variaties in de afstand tussen de tractor en het werktuig op te vangen, zowel tijdens het draaien van de tractor als tijdens de beweging van de vering op het veld. Kruiskoppelingen aan beide uiteinden van de aftakas vangen de hoekafwijking op tussen de aftakasuitgang van de tractor en de ingang van de versnellingsbak. Deze koppelingen moeten binnen de door de fabrikant gespecificeerde maximale werkingshoek blijven om trillingen, lawaai en voortijdige slijtage te voorkomen. Met de L-25A-versnellingsbak gemonteerd op een correct gedimensioneerde strooierkoppeling, moet de hoek van de aftakasaandrijving onder de 15 graden blijven over het volledige bereik van de trekhaakbeweging van de tractor.<\/p>\n<p>The fertilizer distributor gearbox serves three critical functions that the PTO shaft alone cannot perform. First, it increases rotational speed from 540 RPM PTO input to approximately 1,501 RPM at the output, matching the disc speed required for effective fertilizer throw and lateral distribution. Second, it redirects the rotational axis where required by the spreader geometry, allowing vertical disc mounting on horizontally-arranged PTO input systems. Third, it multiplies torque to provide the rotational force needed to overcome the inertia of heavy spreading discs loaded with granular material, especially during startup and when material flow rates are high.<\/p>\n<p>De veiligheidsintegratie tussen de aftakas en de versnellingsbak is eveneens van groot belang. Elke aftakas-aandrijflijn moet voorzien zijn van een slipkoppeling of een overbelastingsbeveiliging met breekbout, geplaatst tussen de uitgang van de tractor en de ingang van de versnellingsbak. Deze beveiliging is zo afgesteld dat het koppel wordt vrijgegeven wanneer de strooischijf vastloopt of een blokkade tegenkomt, waardoor wordt voorkomen dat de impulsbelasting via de versnellingsbak terug in de aandrijflijn van de tractor wordt overgebracht. Zonder deze beveiliging kan een enkele vastgelopen schijf tandwielen breken, de ingaande as afbreken of de transmissie van de tractor beschadigen. CMN Transmission adviseert om bij het bestellen van vervangende of nieuwe aftakas-aandrijflijnen afgestelde aftakassen met vooraf ingestelde slipkoppelingen te gebruiken die geschikt zijn voor de werkbelasting van 5,2 kW \/ 31 N\u00b7m van de L-25A.<\/p>\n<p>The PTO shaft guard or safety shield is a legal requirement in most countries and is an essential safety component that prevents operator contact with the rotating shaft. Both the PTO shaft guard and the gearbox input shield must be correctly fitted and secured at all times during PTO operation. Damaged or missing guards should be replaced before the machine is returned to service. CMN Transmission can supply compatible PTO shaft assemblies with CE-certified safety guards that are dimensionally matched to the L-25A gearbox input connection.<\/p>\n<p>When sourcing a replacement PTO shaft for use with this agricultural gearbox for fertilizer spreader, the key specification parameters include overall collapsed and extended length (to suit the tractor-to-spreader hitch distance), the input and output yoke profiles (to match both the tractor PTO and the gearbox input splines), and the power rating of the slip clutch (which should match the maximum power rating of the L-25A, being 5.2 kW at 540 RPM). Pairing the correct PTO shaft with the L-25A gearbox ensures that the entire drivetrain from tractor to spreading disc operates as a matched, reliable system that delivers consistent spreading performance season after season.<\/p>\n<p>Operators seeking both a replacement fertilizer spreader gearbox and a compatible PTO shaft assembly are encouraged to contact CMN Transmission directly. Our technical team can supply matched gearbox and PTO shaft packages configured to your specific tractor model, spreader type, and hitch geometry, eliminating the risk of dimensional or power-rating mismatches that could compromise both performance and equipment longevity in the field.<\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 50%;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8073 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5.webp\" alt=\"Versnellingsbak voor kunstmeststrooier\" width=\"1000\" height=\"1000\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5.webp 1000w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5-980x980.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1000px, 100vw\" \/><\/td>\n<td style=\"width: 50%;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-343 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft.webp\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1000px, 100vw\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft.webp 1000w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft-980x980.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft-480x480.webp 480w\" alt=\"PTO-as\" width=\"1000\" height=\"1000\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>How to Select the Right Fertilizer Spreader Gearbox<\/h2>\n<p>1. Belastingscapaciteit en vermogen<br \/>\nThe gearbox must be rated for the full combined mechanical load of the fertilizer material weight, disc inertia, and spreading resistance under your specific operating conditions. The L-25A is rated at 5.2 kW and 31 N\u00b7m, which is appropriate for single-disc compact spreaders. For twin-disc or large-capacity hopper spreaders, evaluate whether a higher power rating from the CMN Transmission fertilizer spreader gearboxes range is required before ordering.<\/p>\n<p>2. Gear Ratio and Spreading Speed<br \/>\nThe fertilizer spreader gearbox ratio directly controls the disc rotational speed and therefore the lateral throw distance and spreading width. The 1:2.78 ratio of the L-25A is matched to standard 540 RPM PTO applications where a moderate disc speed is required for granular fertilizers across typical arable field widths. If your spreading prescription requires a different disc speed, CMN Transmission can advise on alternative ratio models from our agricultural gearbox catalogue.<\/p>\n<p>3. Material and Build Durability<br \/>\nFertilizer spreading environments are exceptionally corrosive due to the hygroscopic and reactive nature of common fertilizer compounds. Aluminium housings, as used in the L-25A, provide excellent corrosion resistance at lower weight than cast iron. Internal gears and shafts should be case-hardened alloy steel with precision-ground tooth profiles. Verify that any fertilizer spreader gearbox under consideration uses sealed bearings and chemical-resistant shaft seals before purchasing.<\/p>\n<p>4. Dimensional Compatibility<br \/>\nFor replacement applications, ensure that the replacement gearbox matches OEM mounting dimensions, flange bolt pattern, input spline size, and output shaft diameter exactly. The L-25A Comer replacement from CMN Transmission is dimensionally matched to the original Comer gearbox, ensuring bolt-on installation without frame modification. For new spreader builds, share your frame drawing and shaft requirements with our fertilizer spreader suppliers team for a confirmed fitment check.<\/p>\n<p>5. Maintenance Accessibility<br \/>\nA gearbox that is difficult to service in the field will accumulate deferred maintenance, shortening service life and increasing total ownership cost. The L-25A features accessible oil fill and drain plugs, a simple oil-bath lubrication system requiring only periodic oil changes, and modular seal and bearing components that are widely available from CMN Transmission. When comparing fertilizer spreader gearbox manufacturers, always evaluate the availability and cost of wear parts before making a purchasing decision.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8021 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91.webp\" alt=\"T-281A Kunstmeststrooier Versnellingsbak 1-2.91\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Waarom kiezen voor de kunstmeststrooier-versnellingsbakken van CMN Transmission?<\/h2>\n<p>Korea CMN Transmission Co., Ltd. was established in 2000 and is headquartered in Sandan-o, Danwon-gu, Ansan-si, Gyeonggi-do, Republic of Korea.

Deze CMN Transmission L-25A is ontworpen als een nauwkeurige dimensionale vervanging voor de Comer L-25A versnellingsbak. Het boutpatroon van de montageflens, de specificatie van de ingaande as (1-3\/8\u2033 zesvoudige as), de diameter van de uitgaande as (22 mm) en de totale afmetingen van de behuizing komen overeen met de originele Comer-unit. In de meeste gevallen hoeft u alleen de oude unit los te schroeven en de nieuwe vast te schroeven, zonder dat u het frame hoeft aan te passen of adapterplaten hoeft te gebruiken. Als u een niet-standaard Comer-variant heeft, deel dan het serienummer van uw machine met ons technische team ter bevestiging voordat u bestelt.<\/p>\n<p><strong>Q: What type and quantity of oil does the L-25A fertilizer spreader gearbox require?<\/strong><br \/>\nA: The L-25A requires SAE 80W-90 mineral gear oil, with a maximum fill capacity of 0.35 litres. All gearboxes are supplied dry (without oil), so you must fill to the correct level before the first run. To check the fertilizer spreader gearbox oil level, remove the level check plug on the housing side and verify oil is present at the plug bore level. The first oil change should be carried out at 50-70 operating hours to purge any assembly debris, and subsequently every 500 hours or at least once per year. Using incorrect oil viscosity or contaminated oil will accelerate internal wear.<\/p>\n<p><strong>Q: What does the 1:2.78 fertilizer spreader gearbox ratio mean in practice?<\/strong><br \/>\nA: A 1:2.78 fertilizer spreader gearbox ratio means that for every single revolution of the PTO input shaft, the gearbox output shaft completes 2.78 revolutions. At the standard 540 RPM PTO speed, the output shaft therefore rotates at approximately 1,501 RPM. This step-up ratio is specifically chosen for single-disc fertilizer spreaders that require a higher rotational speed at the disc than the PTO can directly provide, ensuring adequate centrifugal force for lateral throw of granular fertilizer. If you need a different disc speed for your specific spreading application, CMN Transmission offers alternative ratio models.<\/p>\n<p><strong>Q: What is the maximum power and torque rating of this agricultural gearbox?<\/strong><br \/>\nA: De L-25A heeft een maximaal ingangs- en uitgangsvermogen van 5,2 kW (7 pk) bij 540 tpm, met een maximaal uitgangskoppel van 31 N\u00b7m. Deze waarden defini\u00ebren de bovengrens van de continue werking van de versnellingsbak en mogen bij normaal gebruik niet worden overschreden. Voor toepassingen die een hoger vermogen vereisen, zoals zware dubbele schijfstrooiers of trechtersystemen met een hoge capaciteit, dient u het assortiment grotere landbouwversnellingsbakken van CMN Transmission voor kunstmeststrooiers te overwegen. Neem contact op met ons technische team en deel uw vermogens- en koppelvereisten voor een productadvies.<\/p>\n<p><strong>Q: Can I use this gearbox with fertilizers other than granular NPK products?<\/strong><br \/>\nA: Yes. The L-25A is compatible with a wide range of granular materials including NPK blends, single-nutrient fertilizers (urea, ammonium nitrate, muriate of potash), lime prills, pelleted compost, and granulated micronutrient products. For liquid fertilizer systems, a different spreader disc and agitator configuration is required, but the gearbox itself is fully compatible with liquid application spreader builds where the disc or agitator loads remain within the 5.2 kW \/ 31 N\u00b7m rating. Always rinse spreader disc and hopper components with fresh water after applying hygroscopic or reactive fertilizers to prevent corrosive residue accumulation.<\/p>\n<p><strong>Q: What is the weight and housing material of the L-25A fertilizer spreader gearbox?<\/strong><br \/>\nA: The L-25A weighs 4.1 kg and features a die-cast aluminium alloy housing. The aluminium construction provides several practical advantages over cast iron alternatives: it is significantly lighter, which simplifies installation and reduces total spreader weight, improving tractor stability and reducing soil compaction on sensitive ground. Aluminium also provides inherent resistance to the corrosive effects of fertilizer chemicals, particularly ammonium-based compounds and potassium chloride. The housing exterior is further protected by an epoxy finish coating to prevent surface corrosion from prolonged fertilizer exposure.<\/p>\n<p><strong>Q: What fertilizer spreader gearbox parts are available as spares from CMN Transmission?<\/strong><br \/>\nA: CMN Transmission stocks a comprehensive range of fertilizer spreader gearbox parts for the L-25A, including input and output shaft oil seals, deep-groove ball bearings, bevel gear sets, housing gaskets, and mounting hardware. Genuine CMN replacement parts are machined to the same specifications as the original components and are the only parts recommended for warranty-approved repairs. To order spare parts, please provide the gearbox model (L-25A), the specific part required, and your quantity. Our parts team can also assist with identifying worn components from photographs or part number references.<\/p>\n<p><strong>Q: Is a warranty provided with the CMN Transmission L-25A fertilizer gearbox?<\/strong><br \/>\nA: Yes, all CMN Transmission agricultural gearboxes are covered by our standard manufacturing warranty against defects in materials and workmanship. The warranty requires that the gearbox be installed, filled with the correct oil, and operated within its rated power and torque limits. Damage resulting from overload, incorrect oil, contaminated lubrication, improper installation, or operation without PTO driveline overload protection is not covered under warranty. Please retain your purchase documentation and contact our after-sales team with any warranty claim enquiries, supported by photographs of the defect and your operating details.<\/p>\n<p><strong>Q: Can CMN Transmission supply custom fertilizer spreader gearboxes to different ratios or shaft configurations?<\/strong><br \/>\nA: Yes. CMN Transmission maintains a catalogue of nearly one thousand agricultural gearbox specifications and can also develop custom agricultural gearbox solutions for OEM manufacturers and specialty machine builders. Whether you require a different fertilizer spreader gearbox ratio, alternative input or output shaft dimensions, a modified mounting flange, or a left-hand rotation variant, our engineering team can review your requirements and advise on standard variants or custom development options. Minimum order quantities apply for fully custom designs. Contact us with your technical specification and application details for a quotation.<\/p>\n<p><strong>Q: What tractor PTO speed is the L-25A fertilizer spreader gearbox compatible with?<\/strong><br \/>\nA: The L-25A is rated and specified for use at 540 RPM PTO input speed, which is the standard low-speed PTO setting on the overwhelming majority of compact to mid-size agricultural tractors used worldwide. It is not designed for use at 1000 RPM PTO speed, which would exceed the rated input speed and would cause significant overspeed of the output shaft. If you need a gearbox for a 1000 RPM PTO application, please contact CMN Transmission to identify a suitable alternative from our broader fertilizer spreader gearboxes product range. We can also advise on intermediate RPM requirements.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8018 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.84-1.webp\" alt=\"T-281A Kunstmeststrooier Versnellingsbak 1.84-1\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.84-1.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.84-1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Klantenrecensies<\/h2>\n<p><strong>James Whitfield, Wheat Farming, United Kingdom<\/strong><br \/>\n\u201cIk gebruik deze L-25A versnellingsbak nu al zo\u2019n acht maanden op mijn Amazone ZA-M dubbele schijvenstrooier en hij werkt perfect. Afgelopen herfst hebben we zo\u2019n 80 hectare tarwe gestrooid met NPK 23-0-10 en de schijfsnelheid bleef de hele tijd constant. Hij weegt bijna niets vergeleken met de originele Comer-unit die we hebben vervangen. De eerste olieverversing vond plaats na 60 uur, zoals aanbevolen, en de olie was schoon. Ik ben er erg blij mee.\u201d<\/p>\n<p><strong>Fernando Albuquerque, Soybean and Corn Farming, Brazil<\/strong><br \/>\n\u201cWe bestelden vier van deze versnellingsbakken voor onze vloot compacte strooiers die we gebruiken op soja- en ma\u00efsvelden in de staat Mato Grosso. De verhouding van 1:2,78 was perfect voor wat we nodig hadden. Alles werd goed verpakt vanuit Korea geleverd in ongeveer 12 dagen. De installatie was eenvoudig omdat het boutpatroon perfect overeenkwam met de frames van onze strooiers. Na drie maanden en ongeveer 150 draaiuren op de meest gebruikte machine hebben we nog geen problemen ondervonden. Goede prijs-kwaliteitverhouding.\u201d<\/p>\n<p><strong>Trevor MacAllister, Crop Farming, Australia<\/strong><br \/>\n\u201cMijn originele Comer-versnellingsbak begaf het midden in het seizoen, precies toen ik hem het hardst nodig had. Ik vond CMN Transmission online en bestelde deze vervangende L-25A. De klantenservice reageerde ontzettend snel, beantwoordde mijn technische vragen dezelfde dag nog en bevestigde de afmetingen voordat ik bestelde. Het onderdeel arriveerde binnen twee weken in het landelijke Queensland en paste er direct op zonder aanpassingen. Het werkt tot nu toe perfect tijdens het natte seizoen.\u201d<\/p>\n<p><strong>Klaus Hoffmeister, Farm Equipment, Germany<\/strong><br \/>\n\u201cWe bestelden deze versnellingsbak ter vervanging van onze oude Comer-unit op de kunstmeststrooier. De kwaliteit is erg goed; de aluminium behuizing is licht en netjes afgewerkt. Het enige kleine minpuntje: de verpakking had iets steviger gemogen. Technisch gezien kloppen de specificaties absoluut, hij past perfect en loopt stil. We zullen zeker weer bij CMN Transmission bestellen.\u201d<\/p>\n<p><strong>Michael Dupont, Lawn and Turf Management, Canada<\/strong><br \/>\n\u201cIk beheer een golfbaan en twee sportcomplexen en we gebruiken een kleine schijvenstrooier voor onze gazonbemesting. De originele versnellingsbak was na ongeveer vijf seizoenen intensief gebruik versleten, wat eerlijk gezegd best lang is. Deze CMN-vervanging is stiller dan het origineel en heeft dezelfde overbrengingsverhouding, dus we hoefden geen instellingen van de strooier aan te passen. We gebruiken 80W-90 Castrol-versnellingsbakolie zoals aanbevolen. Zeer tevreden met de aankoop.\u201d<\/p>\n<p><strong>Antoine Moreau, Wijngaardonderhoud, Frankrijk<\/strong><br \/>\n\u201cWe gebruiken kunstmeststrooiers in onze wijngaarden in Bourgondi\u00eb en de versnellingsbakken krijgen het zwaar te verduren op de hellingen. We hebben drie van deze L-25A-units besteld als reserveonderdelen voor de werkplaats en \u00e9\u00e9n is al gemonteerd. Geen lawaai, geen lekkages en de aluminium behuizing lijkt bestand tegen onze kaliumsulfaattoepassingen zonder te corroderen. De technische documentatie die bij de unit wordt geleverd, is zeer compleet. De verzending naar Frankrijk duurde ongeveer 10 werkdagen, wat acceptabel is.\u201d<\/p>\n<p><strong>Roberto Perez Vega, landbouwmachines, Mexico<\/strong><br \/>\n\u201cWe hebben deze versnellingsbak gekocht als reserveonderdeel voor onze kunstmeststrooier in Guadalajara. We gebruiken hem nu al vier maanden intensief voor ma\u00efs en sorghum en hij werkt perfect. Het verkoopteam heeft ons geholpen de compatibiliteit met ons strooiermodel te controleren voordat we hem kochten, wat we zeer op prijs stelden. De prijs is zeer concurrerend in vergelijking met andere Europese merken. We bevelen hem zeker aan.\u201d<\/p>\n<p><strong>Rajiv Choudhary, Akkerbouw, India<\/strong><br \/>\n\u201cOns bedrijf heeft 10 L-25A-versnellingsbakken besteld en ze voldeden allemaal aan de juiste specificaties. Ze passen ook perfect op onze kunstmeststrooier. Het team van CMN Transmission heeft al onze technische vragen zeer snel beantwoord. De kwaliteit is erg goed en de prijs is ook redelijk. We zijn van plan om er volgend seizoen meer te bestellen.\u201d<\/p>\n<p><strong>Carlos Mendez Bianchi, Soja- en tarweteelt, Argentini\u00eb<\/strong><br \/>\n\u201cIk heb dit als noodvervanging besteld toen onze hoofdversnellingsbak het begaf tijdens het pampa-strooiseizoen. CMN Transmission verwerkte de bestelling dezelfde dag nog en regelde luchtvracht, waardoor we het binnen zes dagen ontvingen. We hebben het 's avonds gemonteerd en konden de volgende ochtend alweer aan de slag. Het heeft nu meer dan 80 uur gedraaid en werkt perfect. Ik heb niets aan te merken op het product of de service. We zullen er vanaf nu twee als reserveonderdelen op locatie hebben.\u201d<\/p>","protected":false},"excerpt":{"rendered":"<p>The L-25A Fertilizer Spreader Gearbox Ratio 1:2.78, a direct replacement for the Comer L-25A Gearbox, is also widely known as a fertilizer distributor gearbox.
