\"T-281A \"T-281A \"T-281A<\/p>\n

Features of the T-281A Fertilizer Spreader Gearbox 2.16:1<\/h2>\n

1. Ratio Configuration & Output Options
\nThe 2.16:1 gear ratio of this fertilizer spreader gearbox is specifically calibrated to convert 540 r\/min PTO input into the optimal disc rotational speed for uniform centrifugal spreading. With gear arrangements of 25-26 \/ 27-28 (increasing) and 5-6 (reducing), the unit can support multiple output shaft configurations for single-disc, twin-disc, or agitator-combined spreader designs. CMN also offers adjacent ratio options from the same T-281 series to suit operators requiring different disc RPMs for specialty crops or variable-rate application programmes.<\/p>\n

2. Korroosionkest\u00e4v\u00e4 rakenne
\nFertilizer, particularly nitrogen-based and phosphate compounds, is aggressively corrosive to unprotected metal surfaces. The T-281A agricultural gearbox addresses this with a precision die-cast aluminium alloy housing that naturally resists rust and chemical attack. Internal components are protected by high-performance 80W-90 gear oil retained by nitrile rubber lip seals on every shaft, preventing both lubricant leakage and moisture or fertilizer ingress. Protective coatings on ferrous internal parts further extend service life in environments with high humidity and chemical exposure.<\/p>\n

3. Voimanottoakselin liit\u00e4nt\u00e4 ja ura-akselin yhteensopivuus
\nKaikissa kolmessa akseliliitoksessa (X, Y, Z) on alan standardin mukainen 1-3\/8 tuuman Z6-uraprofiili, joka varmistaa suoran ja t\u00e4rin\u00e4tt\u00f6m\u00e4n sovituksen traktoreiden vakiomallisiin voimanottoakseleihin, joiden nopeus on 540 r\/min. Urien oikea yhteensovitus on kriittist\u00e4: ep\u00e4sopivat liitokset aiheuttavat haitallista voimansiirtoakselin t\u00e4rin\u00e4\u00e4, kiihdytt\u00e4v\u00e4t laakerien kulumista ja voivat aiheuttaa akselin v\u00e4symismurtumia. CMN:n tarkkuuskoneistetut urat pidet\u00e4\u00e4n tiukoissa mittatoleransseissa, mik\u00e4 takaa turvallisen ja varman kytkenn\u00e4n ilman sovitusholkkeja tai muutoksia.<\/p>\n

4. Agitator & Dual Disc Drive Integration
\nKolmiakselinen rakenne (X-, Y- ja Z-liit\u00e4nt\u00e4pisteet, kunkin mitoitus on 1-3\/8\u2033 Z6) mahdollistaa T-281A:n k\u00e4ytt\u00e4\u00e4 samanaikaisesti sek\u00e4 ensisijaista py\u00f6riv\u00e4\u00e4 kiekkoa ett\u00e4 valinnaista sekoitinakselia.

5. Kentt\u00e4k\u00e4ytt\u00f6kelpoisuus
\nDesigned with the working farmer in mind, the T-281A fertilizer spreader gearbox oil level can be checked and topped up quickly through clearly positioned fill and drain plugs accessible without removing the unit from the machine. The breather vent prevents pressure build-up during thermal cycling, eliminating the forced-seepage failure mode common on poorly designed gearboxes. With a simple 50-70 hour initial oil change and subsequent 500-hour intervals, routine maintenance is predictable, and fertilizer spreader gearbox parts including seals and bearings are stocked globally through the CMN distributor network.<\/p>\n

6. Laaja valikoima maatalouden sovelluksia
\nBeyond the primary role as a fertiliser spreader gearbox, the T-281A series is equally suited for mowers, multi-row rotary tillers, and band saw drives, making it one of the most versatile gearboxes in the CMN product catalogue. Its compact 7 kg aluminium body and standardised four-bolt mounting pattern (4x \u00d811 mm, 54 mm pitch circle) allow it to be retrofitted into a wide variety of OEM and aftermarket machine frames without structural modification, reducing downtime and simplifying machine upgrades in the field.<\/p>\n

7. Direct Comer T-281A Replacement
\nAs an OEM-equivalent agricultural gearbox for fertilizer spreader systems, the CMN T-281A is dimensionally interchangeable with the original Comer T-281A gearbox. All critical bolt patterns, shaft diameters, spline counts, and overall envelope dimensions are matched to Comer specifications, allowing operators to swap the unit without redesigning the mounting bracket or modifying existing PTO shaft assemblies. This direct-fit design minimises machine downtime during busy spreading seasons and removes the uncertainty of sourcing expensive OEM spare parts at short notice.<\/p>\n

How Does the T-281A Fertilizer Distributor Gearbox Work<\/h2>\n

Kun traktorin kuljettaja kytkee voimanottovivun, py\u00f6rimisteho 540 r\/min nopeudella v\u00e4littyy voimanottoakselin kautta voimansiirtolinjaa pitkin ja menee T-281A-lannoitteenlevittimen vaihteistoon tuloakselilla (liit\u00e4nt\u00e4 X). 1-3\/8 tuuman Z6-uraprofiili liittyy suoraan akselin kytkimeen, mik\u00e4 luo j\u00e4yk\u00e4n, v\u00e4lyksen minimoivan k\u00e4ytt\u00f6liit\u00e4nn\u00e4n, joka siirt\u00e4\u00e4 v\u00e4\u00e4nt\u00f6momentin tehokkaasti ilman luistamista tai t\u00e4rin\u00e4\u00e4. Koska t\u00e4m\u00e4 lannoitteen vaihteisto on mitoitettu enimm\u00e4istulonopeudelle 540 r\/min ja enimm\u00e4istuloteholle 10,3 kW, se pystyy k\u00e4sittelem\u00e4\u00e4n turvallisesti pienten ja keskisuurten traktoreiden t\u00e4yden voimanottotehon koko levitysoperaation ajan.<\/p>\n

Inside the aluminium housing, the incoming high-speed, low-torque rotation from the PTO passes through a precision-cut bevel gear set. The 2.16:1 gear ratio means that for every 2.16 revolutions of the input shaft, the output shaft completes one revolution at a proportionally higher torque value. In practical terms, the maximum output torque delivered to the spreading discs or agitators is 82 N\u00b7m, which is sufficient to accelerate even dense granular fertilizer products to the disc speeds required for consistent spread patterns across widths of 8 to 24 metres, depending on spreader design and vane configuration.<\/p>\n

T-281A-lannoitteenlevittimen vaihteistossa on kolme akselin liitoskohtaa (X, Y, Z), jotka kaikki on koneistettu 1-3\/8 tuuman Z6-urastandardin mukaisesti. T\u00e4m\u00e4 kolmiakselinen rakenne mahdollistaa vaihteiston k\u00e4ytt\u00e4\u00e4 samanaikaisesti ensisijaista kiekkoa (Y-akseli), toissijaista kiekkoa tai sekoitinta (X-akseli) ja takaulostuloa (Z-akseli) levittimen rakenteesta riippuen. Akselien v\u00e4linen voimanjako hallitaan sis\u00e4isell\u00e4 vaihteistoj\u00e4rjestelyll\u00e4, mik\u00e4 varmistaa tasapainoisen kuorman jakautumisen ja est\u00e4\u00e4 ep\u00e4symmetriset kiekkonopeudet, jotka muuten aiheuttaisivat ep\u00e4tasaisia \u200b\u200blevityskuvioita ja lannoiteh\u00e4vikki\u00e4.<\/p>\n

The gearbox runs in a sealed oil bath of SAE 80W-90 gear oil (maximum 0.5 L capacity). This viscosity grade is specifically chosen to maintain an adequate lubricant film between gear flanks and bearing races across a broad operating temperature range, from cold morning starts in temperate climates to sustained high-ambient-temperature operation in tropical agricultural zones. Heat generated by the gear mesh is absorbed by the oil, conducted through the aluminium housing walls, and dissipated into the surrounding air. The first oil change at 50-70 hours removes metal break-in particles; subsequent 500-hour intervals (or annual changes) maintain oil cleanliness and gearbox longevity.<\/p>\n

Each rotating shaft exits the housing through a lip-type oil seal that simultaneously retains internal lubricant and excludes external contaminants including fertilizer dust, soil particles, and moisture. A breather vent maintains pressure equilibrium inside the housing as the oil heats and cools during work cycles, preventing seal distortion or forced oil expulsion. The robust sealing system is particularly important on fertilizer spreader gearboxes because ammonium nitrate and urea-based fertilizers are hygroscopic and corrosive; even trace infiltration can attack steel bearing races within a single season if seals are compromised.<\/p>\n

The T-281A agricultural gearbox for fertilizer spreaders is bolted to the spreader frame via four M10 mounting holes arranged in a 108 mm x 108 mm square bolt pattern (4x \u00d811 mm through-holes at 54 mm pitch in both axes). This four-point rigid mount effectively transfers the reaction torque from the gear set into the machine frame rather than allowing it to stress the PTO shaft or driveline components. The compact overall envelope (approximately 105 mm wide x 156 mm tall from mounting face to output shaft centre) accommodates tight installation spaces on compact and mid-size spreaders without structural modification.<\/p>\n

Sports field managers, golf course superintendents, and turf contractors rely on precision fertiliser spreader gearboxes to deliver granular fertilizers and slow-release nutrients uniformly across closely maintained turf surfaces. Uneven application at these precision settings causes visible striping and differential growth. The consistent 2.16:1 ratio and 82 N\u00b7m output torque of the T-281A ensure disc speed stability even at low tractor forward speeds, producing the fine, even spread patterns that premium turf management demands.<\/p>\n<\/div>\n

Precision Bearings
\nEach shaft is supported at both ends by precision-grade bearings selected for the specific loading pattern at that position. Input shaft bearings are typically deep-groove ball bearings to handle the combination of radial PTO loads and moderate axial thrust from the bevel gear mesh. Output shaft positions may use a combination of ball and angular contact or tapered roller elements to resist the higher axial loads generated as spinning discs react against the fertilizer mass. All bearings are grease-packed and oil-bath lubricated for maximum service life.<\/p>\n

Lip Oil Seals
\nRadial lip seals manufactured from fluoroelastomer (FKM) or acrylonitrile butadiene rubber (NBR) are installed at each shaft exit point on the aluminium housing. These seals maintain a dynamic seal against the rotating shaft surface, retaining lubricating oil inside the gear chamber while excluding fertilizer dust, soil debris, and moisture from outside. Seal condition should be visually inspected at each oil change; evidence of oil weeping around any shaft indicates a seal nearing the end of service life and requiring replacement before it allows lubricant loss or contaminant ingress.<\/p>\n

Voiteluj\u00e4rjestelm\u00e4
\nThe T-281A fertilizer spreader gearbox oil level is managed through three clearly identified ports on the housing: a fill plug at the top, a level check plug at mid-height (the oil level is correct when oil reaches the lower edge of this port), and a drain plug at the bottom for complete oil changes. A calibrated breather vent prevents vacuum or pressure build-up inside the housing as temperature fluctuates during operation, protecting seals and gaskets from pressure-induced failure without allowing unfiltered external air to enter the oil chamber.<\/p>\n

How to Install the T-281A Gearbox on Your Fertilizer Spreader<\/h2>\n

1. Inspect and Prepare the Mounting Frame
\nEnnen T-281A-vaihteiston asennusta puhdista levittimen vaihteiston kiinnitysrunko huolellisesti ja tarkista se halkeamien, v\u00e4\u00e4ntymien tai ruostevaurioiden varalta. Varmista, ett\u00e4 kaikki nelj\u00e4 kiinnityspultin reik\u00e4\u00e4 ovat linjassa vaihteiston 4x \u00d811 mm:n kuvion kanssa 108 mm x 108 mm:n neli\u00f6jaolla. V\u00e4\u00e4ntynyt tai sy\u00f6pynyt runko aiheuttaa v\u00e4\u00e4nt\u00f6j\u00e4nnityst\u00e4 koteloon k\u00e4yt\u00f6n aikana, mik\u00e4 voi ajan my\u00f6t\u00e4 haljeta alumiiniseosvalua tai v\u00e4\u00e4rist\u00e4\u00e4 sis\u00e4ist\u00e4 hammaspy\u00f6r\u00e4st\u00f6n kohdistusta.<\/p>\n

2. Position and Align the Gearbox
\nOffer the T-281A up to the mounting frame and hand-tighten all four bolts before applying final torque. Check that the output shaft (Z position, pointing downward on a standard centrifugal spreader) is centred over the disc hub and that the input shaft axis is co-linear with the PTO driveshaft axis within 1 degree of angular misalignment. Use a straightedge or dial indicator across the coupling faces if precision alignment is critical, particularly on machines that run continuously at full PTO speed for extended periods.<\/p>\n

3. Torque the Mounting Bolts to Specification
\nKirist\u00e4 kaikki nelj\u00e4 kiinnityspulttia kalibroidulla momenttiavaimella diagonaalisessa (ristikk\u00e4isess\u00e4) j\u00e4rjestyksess\u00e4 levittimen valmistajan k\u00e4ytt\u00f6ohjeessa m\u00e4\u00e4ritettyyn momenttiarvoon, joka on tyypillisesti 40\u201355 N\u00b7m M10-luokan 8.8 pulteille. Diagonaalinen kiristys varmistaa, ett\u00e4 kotelo asettuu tasaisesti kiinnityspintaa vasten ilman keinutusta tai reunakuormitusta, jotka voisivat aiheuttaa j\u00e4nnityskeskittymi\u00e4 alumiinikotelon valukappaleeseen pulttien napojen l\u00e4hell\u00e4. Tarkista momentti uudelleen ensimm\u00e4isten 5 k\u00e4ytt\u00f6tunnin j\u00e4lkeen, koska alkusovitus voi aiheuttaa pient\u00e4 l\u00f6ystymist\u00e4.<\/p>\n

4. Connect the PTO Driveshaft
\nLiu'uta voimanottoakselin haarukka vaihteiston tuloakselin yli (liit\u00e4nt\u00e4 X) varmistaen, ett\u00e4 1-3\/8\u2033 Z6-urit kytkeytyv\u00e4t kokonaan v\u00e4hint\u00e4\u00e4n 50 mm:n kytkent\u00e4matkalta. Aseta lukitustappi tai lukkorengas haarukan kaulukseen ja kiinnit\u00e4 se. Kytke sitten vastakkainen p\u00e4\u00e4 traktorin voimanottoakseliin ja kiinnit\u00e4 my\u00f6s se tappi. Tarkista, ett\u00e4 voimanottoakseli ty\u00f6ntyy teleskooppimaisesti keskiasentoon ty\u00f6korkeudella siten, ett\u00e4 p\u00e4\u00e4llekk\u00e4isyytt\u00e4 j\u00e4\u00e4 v\u00e4hint\u00e4\u00e4n 50 mm maksimiasennossa ja v\u00e4lyst\u00e4 v\u00e4hint\u00e4\u00e4n 25 mm minimikorkeudessa t\u00e4ydest\u00e4 kokoonpuristuksesta.<\/p>\n

5. Fill with the Correct Grade of Gear Oil
\nThe T-281A fertilizer spreader gearbox is supplied dry. Before the first start, remove the fill plug at the top of the housing and fill with SAE 80W-90 gear oil until oil reaches the lower edge of the level check port on the side of the housing. The maximum oil capacity is 0.5 L. Use only the specified viscosity grade; lighter oils reduce film thickness under load while heavier grades increase churning losses and heat at low temperatures. Replace both plugs securely and wipe away any spillage to prevent slipping hazards and to make future oil leak detection easier.<\/p>\n

6. Attach the Spreading Discs or Output Implements
\nKytke py\u00f6riv\u00e4n lautasen napa(t) tai ty\u00f6koneen k\u00e4ytt\u00f6kytkimet sopiviin ulostuloakseleihin (Y ja\/tai Z tai X levittimen rakenteesta riippuen) varmistaen, ett\u00e4 urat ovat t\u00e4ysin kiinni ja lukitustapit ovat kokonaan paikallaan. Varmista, ett\u00e4 kaikki lautasten ter\u00e4t, siivet ja melat on asetettu oikein ja kiristetty valmistajan m\u00e4\u00e4ritt\u00e4mien v\u00e4\u00e4nt\u00f6momenttien mukaisesti. Ep\u00e4tasapainoinen lautaskokoonpano aiheuttaa syklisi\u00e4 v\u00e4r\u00e4htelykuormia, jotka kiihdytt\u00e4v\u00e4t laakerien kulumista maatalousvaihteiston sis\u00e4ll\u00e4 ja voivat aiheuttaa kotelon ennenaikaista v\u00e4symist\u00e4, jos sit\u00e4 ei korjata.<\/p>\n

7. Run-In Check and First Operation Inspection
\nEngage the tractor PTO at low idle speed (approximately half the rated 540 r\/min) for 5 minutes and observe the gearbox for any unusual noise, vibration, or oil seepage around shaft seals and housing joints. Then bring PTO speed up to the full 540 r\/min operating rate and run for a further 10 minutes under no-load conditions before loading the spreader hopper. Conduct the first oil change after 50-70 operating hours to remove any metallic particles generated during gear and bearing break-in, then revert to the standard 500-hour interval.<\/p>\n

\n

Initial Oil Fill and First Oil Change at 50-70 Hours<\/h3>\n

The T-281A fertilizer spreader gearbox is supplied dry and must be filled with 0.5 L of SAE 80W-90 gear oil before first use. A critical maintenance step specific to new gearboxes is the first oil change at 50-70 operating hours, well ahead of the standard 500-hour interval. During break-in, the gear flanks, bearing races, and seal lips generate metallic particles as microscopic surface asperities wear smooth. These particles remain suspended in the oil and act as abrasive agents if not flushed out promptly. The early oil change removes this break-in contamination and sets the gearbox up for a full service life.<\/p>\n<\/div>\n

\n

Regular Fertilizer Spreader Gearbox Oil Level Checks<\/h3>\n

Check the fertilizer spreader gearbox oil level at the start of each spreading season and every 50 hours of operation during heavy use periods. To check, remove the level plug on the side of the housing; oil should be flush with the bottom edge of this port. If the level is low, top up through the fill plug using the same grade of 80W-90 gear oil already in the housing. Never mix different oil grades or brands, as additive incompatibility can cause foam formation, reduced film strength, and accelerated wear. A consistently low oil level between scheduled checks indicates a seal leak that must be diagnosed and repaired before the next operation.<\/p>\n<\/div>\n

\n

Annual Oil Change and Housing Inspection<\/h3>\n

Even on machines that do not accumulate 500 operating hours in a year, CMN recommends a full drain-and-refill oil change at least once annually, ideally at season end before winter storage. Drain the old oil into a suitable container, inspect it for unusual metallic sediment or a milky emulsified appearance (a sign of water contamination through a compromised seal), and dispose of the used oil responsibly through an authorised recycling facility. While the drain plug is out, use a flashlight to look into the housing through the drain port for any visible gear tooth damage or foreign material before filling with fresh 80W-90 oil.<\/p>\n<\/div>\n

\n

Shaft Seal Inspection and Replacement<\/h3>\n

Inspect all three shaft seal positions (X, Y, Z) visually at each oil level check. A thin oil film around the shaft exit is acceptable during run-in but persistent oil weeping after 50 hours indicates a failed or misaligned lip seal. Fertilizer and dust adhering to the weeping oil zone accelerates corrosion of the shaft journal surface, leading to progressive seal wear and eventually bearing contamination. Replace any leaking seal promptly, using only genuine CMN replacement seals dimensioned to the original shaft diameter to ensure correct interference fit and dynamic sealing performance.<\/p>\n<\/div>\n

\n

Mounting Bolt and Housing Fastener Checks<\/h3>\n

Vibration from the PTO driveline, disc imbalance, and rough field travel can gradually loosen the four housing mounting bolts over a season of intensive use. Include a mounting bolt torque check in the pre-season service routine and after the first 5-10 hours of operation on a new installation. Use a calibrated torque wrench to verify that all bolts are at the specified torque. Also inspect the housing for hairline cracks around the bolt bosses or at the shaft seal positions; small cracks in the aluminium casting indicate overload or misalignment events that must be investigated before returning the machine to operation.<\/p>\n<\/div>\n

\n

Post-Season Cleaning and Storage Preparation<\/h3>\n

After the final spreading operation of the season, disconnect the fertilizer spreader gearbox from the PTO shaft and thoroughly clean the external housing with warm water and a mild detergent, paying particular attention to the shaft seal areas where fertilizer residue accumulates. Allow the housing to dry completely, then spray the shaft seal lips and spline profiles lightly with a water-displacing corrosion inhibitor. Store the gearbox in a dry, ventilated space away from direct sunlight and fertilizer vapours. Protect the shaft splines from corrosion with a light coating of anti-seize compound before storing the machine, making reinstallation at the start of the next season easier and damage-free.<\/p>\n<\/div>\n

\n

Breather Vent Maintenance<\/h3>\n

The breather vent on the T-281A housing performs the essential function of pressure equalisation during thermal cycling. If this vent becomes clogged with fertilizer dust, dried oil deposits, or soil, pressure will build inside the housing during operation and force oil past the shaft seals, causing apparent seal failures that are in fact caused by blocked ventilation rather than worn seals. Inspect and clean the breather vent at each seasonal service using a fine wire and compressed air. A blocked vent is one of the most commonly overlooked root causes of premature seal failure on working fertilizer spreader gearboxes in high-dust field conditions.<\/p>\n<\/div>\n

Suosittelemme tarkistamaan koneesi asennuspiirustuksen teknisest\u00e4 datalehdest\u00e4mme ennen tilaamista, jos olet ep\u00e4varma koneesi sukupolvesta.<\/p>\n

Q: What oil type should I use for the T-281A fertilizer gearbox, and what is the correct oil level?<\/strong>
\nA: Use SAE 80W-90 GL-4 or GL-5 gear oil. The maximum oil capacity is 0.5 L. The correct fertilizer spreader gearbox oil level is reached when oil is flush with the lower edge of the level check port on the side of the housing. Fill through the top fill plug until oil reaches this level. Do not overfill, as excess oil generates heat through churning and may be forced out through the shaft seals. Contact us if you need confirmation of a specific local oil brand that meets the SAE 80W-90 specification.<\/p>\n

Q: What is the fertilizer spreader gearbox ratio of the T-281A and how does it affect spread width?<\/strong>
\nA: The T-281A has a 2.16:1 ratio, meaning the output shafts rotate once for every 2.16 input revolutions, producing approximately 250 r\/min output at standard 540 r\/min PTO speed. This output speed is optimised for medium-spread-width centrifugal disc spreaders. A higher disc RPM (achieved with a lower ratio such as 1.35:1) produces a wider spread pattern at the cost of reduced torque; a lower disc RPM (higher ratio such as 2.91:1) reduces spread width but increases disc torque for dense or heavy material. CMN offers the full T-281 series across ratios from 1.00:1 to 2.91:1 to match any spreading requirement.<\/p>\n

Q: How often should I change the oil in my T-281A agricultural gearbox?<\/strong>
\nA: Perform the first oil change after 50-70 operating hours to flush out break-in metallic particles. Thereafter, change the oil every 500 hours of operation or at least once per year, whichever comes first. In high-dust conditions or when spreading corrosive materials such as ammonium sulphate, reduce the change interval to 250-300 hours. Always dispose of used gear oil responsibly through an authorised recycling facility. Use fresh SAE 80W-90 gear oil for every refill.<\/p>\n

Q: Can the T-281A gearbox be used on spreaders that need twin-disc or agitator drive outputs?<\/strong>
\nV: Kyll\u00e4. T-281A:ssa on kolme ulostuloakselin liit\u00e4nt\u00e4pistett\u00e4 (X, Y, Z), joista jokainen on koneistettu 1-3\/8\u2033 Z6-urakiinnityksen standardin mukaisesti. T\u00e4m\u00e4 rakenne mahdollistaa ensisijaisen levityslautasen (yleens\u00e4 Z-akseli), toissijaisen lautasen tai sekoittimen (Y-akseli) ja apuulostulon (X-akseli) samanaikaisen k\u00e4yt\u00f6n, jos levittimen rakenne sit\u00e4 vaatii.

Q: My fertilizer spreader gearbox is leaking oil around the shaft seal. What should I do?<\/strong>
\nA: A shaft seal leak is most commonly caused by: (1) a blocked breather vent creating internal pressure that forces oil past the seal lip; (2) a worn or damaged seal requiring replacement; or (3) overfilling the gearbox with oil above the correct level. First, check and clean the breather vent. If the leak continues, check the oil level and drain excess if overfilled. If the problem persists with a clean vent and correct oil level, the shaft seal requires replacement. Contact your CMN distributor for a genuine replacement seal kit matched to the T-281A shaft dimensions. Continuing to operate with a known seal leak accelerates bearing damage and risks spreading contaminated oil in the field.<\/p>\n

Q: What is the maximum tractor PTO power the T-281A fertilizer spreader gearbox can handle?<\/strong>
\nA: The T-281A is rated for a maximum input power of 10.3 kW (approximately 14 HP) at 540 r\/min. This is suitable for compact to mid-size tractors commonly paired with single-disc or light twin-disc centrifugal fertilizer spreaders. Do not use this gearbox on tractor and spreader combinations that regularly demand more than 10.3 kW at the PTO; doing so will cause accelerated gear wear, overheating, and possible housing failure. For higher-power applications, CMN offers larger-format gearboxes from the T-281 series range rated to 16.9 kW (292 N\u00b7m output torque). Contact us for the correct specification for your machine.<\/p>\n

\n\u201dViljelemme noin 1 400 hehtaaria vehn\u00e4\u00e4 ja maissia Pampas-vuorilla. Rauch-levittimemme alkuper\u00e4inen vaihteisto oli kulunut loppuun kuuden kauden j\u00e4lkeen, ja Comerin vaihtoautohinta oli yksinkertaisesti liian korkea. Tilasin kaksi CMN T-281A -levitint\u00e4 tammikuussa. Ne saapuivat Buenos Airesiin t\u00e4ydellisess\u00e4 kunnossa, molempien urat t\u00e4sm\u00e4lleen kohdillaan, ja pultasimme ne paikoilleen iltap\u00e4iv\u00e4n sis\u00e4ll\u00e4. Teimme ensimm\u00e4isen \u00f6ljynvaihdon noin 55 tunnin kohdalla ohjeidenne mukaisesti, ja \u00f6ljy tuli ulos puhtaana, ja siin\u00e4 oli vain v\u00e4h\u00e4n hienoa metallip\u00f6ly\u00e4. Kaksi kautta my\u00f6hemmin molemmat toimivat edelleen t\u00e4ydellisesti ilman vuotoja.\u201d<\/p>\n

\n\u201dOstin 2.16:1 T-281A -vaihteiston korvaamaan kuluneen Corer-vaihteiston Amazone ZA-TS 4200 -mallissani. Vaihteisto saapui Ohioon noin 11 p\u00e4iv\u00e4ss\u00e4 hyvin pakattuna ja vahingoittumattomana. Sopivuus oli t\u00e4ydellinen, adapteria ei tarvittu. Olen ajanut sill\u00e4 noin 320 tuntia kahden maissi- ja soijapapulannoitteen kauden aikana, ja se on toiminut t\u00e4ysin ongelmattomasti. Se k\u00e4y hiljaa, ei vuotoja, \u00f6ljytason tarkistusruuviin on helppo p\u00e4\u00e4st\u00e4 k\u00e4siksi, toisin kuin vanhan kanssa. Ostaisin ehdottomasti uudelleen.\u201d<\/p>\n

\n\u201dMeill\u00e4 on nurmikoiden ja urheilunurmien hoitoyritys Kentiss\u00e4 ja tarvitsemme levittimiemme luotettavan toiminnan koko kev\u00e4t- ja syksyn pintalevityskauden ajan. T-281A saapui Koreasta viikon sis\u00e4ll\u00e4, mik\u00e4 rehellisesti sanottuna yll\u00e4tti minut. Alumiinikotelo on huomattavasti kevyempi kuin vanha valurautainen Comer, mik\u00e4 helpotti levittimen k\u00e4sittely\u00e4 kolmipistekiinnityksell\u00e4. Urituksen ja hammaspy\u00f6r\u00e4st\u00f6n viimeistelyn laatu n\u00e4ytt\u00e4\u00e4 minusta erinomaiselta. Noin 180 k\u00e4ytt\u00f6tunnin j\u00e4lkeen se toimii t\u00e4sm\u00e4lleen odotetusti, eik\u00e4 mit\u00e4\u00e4n valittamista ole.\u201d<\/p>\n

\n\u201dHallin viinitarhaa Burgundissa, ja k\u00e4yt\u00e4mme keskipakoislevitint\u00e4 rakeisen rikin ja kalkkikiven levitt\u00e4miseen viinik\u00f6ynn\u00f6srivien v\u00e4liin. T-281A saapui Ranskaan 9 p\u00e4iv\u00e4ss\u00e4 ilman kuljetuksen aikana tapahtuneita vaurioita. Kokoaminen kesti alle tunnin, koska mitat vastaavat t\u00e4ydellisesti alkuper\u00e4ist\u00e4 Comeria. Eniten minuun teki vaikutuksen alumiinikotelon kest\u00e4vyys ja tiivistyksen laatu. 140 k\u00e4ytt\u00f6tunnin j\u00e4lkeen ei ole vuotoja eik\u00e4 ep\u00e4normaaleja \u00e4\u00e4ni\u00e4. Olen eritt\u00e4in tyytyv\u00e4inen.\u201d<\/p>\n

\n\u201dMinulla on koneliike New South Walesissa ja varastossani on CMN T-281A -vaihteistoa edullisena korvaajana t\u00e4\u00e4ll\u00e4 suosituissa Vicon- ja Bogballe-levittimiss\u00e4 oleville Comer-vaihteistoille. Maanviljelij\u00e4t rakastavat sit\u00e4, koska he voivat tilata sen kauttani paikallisesti sen sijaan, ett\u00e4 odottaisivat kalliita maahantuotuja alkuper\u00e4isosia. V\u00e4lityssuhde on t\u00e4sm\u00e4lleen 2,16:1, kuten mainittiin. Rakentamisen laatu on tehnyt vaikutuksen korjaamoteknikkoihini. Viimeisten 18 kuukauden aikana olemme myyneet ja asentaneet yli 30 t\u00e4llaista yksikk\u00f6\u00e4, eik\u00e4 takuuvaatimuksia ole tullut yht\u00e4\u00e4n. CMN:n j\u00e4lkimarkkinointituki on my\u00f6s ollut eritt\u00e4in avulias, kun minulla on ollut teknisi\u00e4 kysymyksi\u00e4.\u201d<\/p>\n

\n\u201dViljen noin 900 hehtaaria Baijerissa ja k\u00e4yt\u00e4n keskipakoislevittimi\u00e4 peruslannoitukseen. Kun vanhan levittimeni Comer-vaihteisto hajosi, tilasin CMN T-281A:n tilalle. Toimitus M\u00fcncheniin kesti 10 p\u00e4iv\u00e4\u00e4, ja pakkaus oli t\u00e4ysin kunnossa. Asennus ei mennyt juurikaan aikaa, sill\u00e4 kaikki mitat ovat identtiset Comerin kanssa. Se k\u00e4y eritt\u00e4in hiljaisesti, eik\u00e4 \u00f6ljyvuotoja tapahdu 250 k\u00e4ytt\u00f6tunnin j\u00e4lkeen. Hinta-laatusuhde on huomattavasti parempi kuin alkuper\u00e4isess\u00e4 varaosassa. Aion muuttaa lis\u00e4\u00e4 laitteitani.\u201d<\/p>\n

\n\u201dHallinnoimme suurta sokeriruokotilaa S\u00e3o Paulon osavaltiossa ja k\u00e4yt\u00e4mme useita traktoriin kiinnitett\u00e4vi\u00e4 keskipakoislevittimi\u00e4 NPK- ja kalkkiohjelmassamme. Vaihdoimme nelj\u00e4 vanhaa vaihteistoa T-281A-vaihteistoihin viime kaudella. Toimitus Brasiliaan kesti noin 14 p\u00e4iv\u00e4\u00e4 lentorahtina, mik\u00e4 oli hyv\u00e4ksytt\u00e4v\u00e4\u00e4 ottaen huomioon hintas\u00e4\u00e4st\u00f6n alkuper\u00e4isvalmistajiin verrattuna. Kaikki nelj\u00e4 vaihteistoa asennettiin ja toimivat kahden p\u00e4iv\u00e4n kuluessa. Mekaanikkoni sanoo, ett\u00e4 alumiinivalujen laatu ja vaihteiston viimeistely ovat huomattavasti parempia kuin joissakin aiemmin kokeilemissamme kiinalaisissa vaihtoehdoissa. Olen eritt\u00e4in tyytyv\u00e4inen p\u00e4\u00e4t\u00f6kseen ostaa CMN:lt\u00e4.\u201d<\/p>\n

\n\u201dHankin laitteita keskikokoisille riisi- ja vehn\u00e4tiloille Punjabissa. Tarvitsimme luotettavan lannoitteenlevittimen vaihteiston ja otimme yhteytt\u00e4 CMN:\u00e4\u00e4n heid\u00e4n verkkosivustonsa kautta. Myyntitiimi vastasi 24 tunnin kuluessa, toimitti kaikki pyyt\u00e4m\u00e4ni tekniset piirustukset, ja l\u00e4hetys saapui Amritsariin hyv\u00e4ss\u00e4 kunnossa 12 p\u00e4iv\u00e4n kuluessa. Vaihteistot ovat nyt olleet k\u00e4yt\u00f6ss\u00e4 noin kahdeksan kuukautta kahden lannoitusjakson ajan. Ei vikoja, ei ongelmia ura-akselin yhteensopivuudessa, ja k\u00e4ytt\u00f6ohjeessa suositellut \u00f6ljyntarkastusv\u00e4lit ovat k\u00e4ytt\u00e4jillemme helppoja noudattaa.\u201d<\/p>\n

The CMN Transmission T-281A Fertilizer Spreader Gearbox, ratio 2.16:1, is a direct replacement for the Comer T-281A gearbox and serves as a critical agricultural gearbox at the heart of centrifugal fertilizer spreaders. Also known as a fertilizer distributor gearbox, it converts tractor PTO rotation (540 r\/min) into the precise output speed and torque required to drive spinning discs or augers that distribute fertilizers, lime, seeds, and granular amendments uniformly across the field. With a maximum output torque of 82 N\u00b7m and a rated input power of 10.3 kW (14 HP), this unit is engineered for consistent, efficient power transfer even under variable load conditions common during intensive crop production cycles.<\/p>","protected":false},"featured_media":8022,"comment_status":"open","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[309],"product_tag":[316,315,311,317,318,319,310],"class_list":{"0":"post-8173","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\/8173","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=8173"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/media\/8022"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/media?parent=8173"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product_brand?post=8173"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product_cat?post=8173"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/fi\/wp-json\/wp\/v2\/product_tag?post=8173"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
