Ratio Configuration &amp; Output Options<br \/>\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<p>2. Korozyona Dayan\u0131kl\u0131 Yap\u0131<br \/>\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<p>3.

Sahada Servis Edilebilirlik<br \/>\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<p>6. Geni\u015f Tar\u0131msal Uygulama Yelpazesi<br \/>\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<p>7. Direct Comer T-281A Replacement<br \/>\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<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8022 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-2.16-1.webp\" alt=\"T-281A G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131 2.16-1\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-2.16-1.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-2.16-1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>How Does the T-281A Fertilizer Distributor Gearbox Work<\/h2>\n<p>Trakt\u00f6r operat\u00f6r\u00fc PTO kolunu devreye soktu\u011funda, 540 dev\/dak'l\u0131k d\u00f6nme g\u00fcc\u00fc PTO \u015faft\u0131 \u00fczerinden tahrik hatt\u0131 boyunca iletilir ve giri\u015f \u015faft\u0131nda (Ba\u011flant\u0131 X) T-281A g\u00fcbre serpme makinesinin di\u015fli kutusuna girer. 1-3\/8\u2033 Z6 spline profili, \u015faft kapliniyle do\u011frudan e\u015fle\u015ferek, kayma veya titre\u015fim olmadan torku verimli bir \u015fekilde aktaran, sa\u011flam ve bo\u015fluksuz bir tahrik ba\u011flant\u0131s\u0131 olu\u015fturur.

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<p>T-281A g\u00fcbre da\u011f\u0131t\u0131c\u0131 \u015fanz\u0131man\u0131, tamam\u0131 1-3\/8\u2033 Z6 spline standard\u0131na g\u00f6re i\u015flenmi\u015f \u00fc\u00e7 \u015faft ba\u011flant\u0131 noktas\u0131na (X, Y, Z) sahiptir.

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<p>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<p>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<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8052 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2.webp\" alt=\"G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131\" width=\"1200\" height=\"820\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2-980x670.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2-480x328.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>Uygulama Senaryolar\u0131<\/h2>\n<div>\n<h3>\u00c7im ve \u00c7imen Bak\u0131m\u0131<\/h3>\n<p>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.

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<p>Lip Oil Seals<br \/>\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<p>Ya\u011flama Sistemi<br \/>\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<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8037 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-3.webp\" alt=\"L-25J G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131 1-3\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-3.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-3-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>How to Install the T-281A Gearbox on Your Fertilizer Spreader<\/h2>\n<p>1.

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<p>6.

Run-In Check and First Operation Inspection<br \/>\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<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8165 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-9.webp\" alt=\"G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131\" width=\"1200\" height=\"820\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-9.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-9-980x670.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-9-480x328.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>Bak\u0131m \u0130pu\u00e7lar\u0131<\/h2>\n<div>\n<h3>Initial Oil Fill and First Oil Change at 50-70 Hours<\/h3>\n<p>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<div>\n<h3>Regular Fertilizer Spreader Gearbox Oil Level Checks<\/h3>\n<p>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<div>\n<h3>Annual Oil Change and Housing Inspection<\/h3>\n<p>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<div>\n<h3>Shaft Seal Inspection and Replacement<\/h3>\n<p>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<div>\n<h3>Mounting Bolt and Housing Fastener Checks<\/h3>\n<p>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<div>\n<h3>Post-Season Cleaning and Storage Preparation<\/h3>\n<p>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<div>\n<h3>Breather Vent Maintenance<\/h3>\n<p>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<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 G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131 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>G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131 ve PTO Tahrik Mili<\/h2>\n<p>G\u00fcbre serpme makinesinin \u015fanz\u0131man\u0131, trakt\u00f6r\u00fcn PTO \u015faft\u0131 ile serpme makinesinin diski veya kar\u0131\u015ft\u0131r\u0131c\u0131 mekanizmas\u0131 aras\u0131nda yer al\u0131r ve ayn\u0131 anda \u00fc\u00e7 i\u015flevi yerine getirir: d\u00f6n\u00fc\u015f eksenini de\u011fi\u015ftirmek, PTO'nun 540 dev\/dak'l\u0131k \u00e7\u0131k\u0131\u015f h\u0131z\u0131n\u0131 diskin optimum \u00e7al\u0131\u015fma h\u0131z\u0131na d\u00fc\u015f\u00fcrmek ve d\u00fc\u015f\u00fck torklu PTO \u015faft \u00e7\u0131k\u0131\u015f\u0131ndan gelen torku, gran\u00fcl g\u00fcbre malzemesinin ataletine kar\u015f\u0131 y\u00fckl\u00fc bir diski h\u0131zland\u0131rmak i\u00e7in gereken daha y\u00fcksek torka d\u00f6n\u00fc\u015ft\u00fcrmek. \u015eanz\u0131man olmadan, PTO \u015faft\u0131 diski tam motor h\u0131z\u0131yla \u00e7al\u0131\u015ft\u0131r\u0131r, kontrol edilemeyen geni\u015f bir serpme deseni olu\u015fturur ve disk kanatlar\u0131na ve g\u00f6bek ba\u011flant\u0131 elemanlar\u0131na a\u015f\u0131r\u0131 merkezka\u00e7 y\u00fckleri uygular.<\/p>\n<p>Eskiden G\u00fc\u00e7 \u00c7\u0131k\u0131\u015f Mili olarak bilinen PTO tahrik mili, trakt\u00f6r\u00fcn arka taraf\u0131na monte edilmi\u015f g\u00fc\u00e7 \u00e7\u0131k\u0131\u015f milinden ba\u011fl\u0131 bir ekipmana d\u00f6nme g\u00fcc\u00fcn\u00fc ileten teleskopik mekanik tahrik milidir.

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<p><strong>Q: What is the fertilizer spreader gearbox ratio of the T-281A and how does it affect spread width?<\/strong><br \/>\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<p><strong>Q: How often should I change the oil in my T-281A agricultural gearbox?<\/strong><br \/>\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<p><strong>Q: Can the T-281A gearbox be used on spreaders that need twin-disc or agitator drive outputs?<\/strong><br \/>\nA: Evet.

What should I do?<\/strong><br \/>\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<p><strong>Q: What is the maximum tractor PTO power the T-281A fertilizer spreader gearbox can handle?<\/strong><br \/>\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<p><strong>Q: Are fertilizer spreader gearbox parts like seals, bearings, and gear sets available separately?<\/strong><br \/>\nA: Yes, CMN Transmission supports the T-281A with a comprehensive spare parts programme. Available fertilizer spreader gearbox parts include: shaft seal kits (all three positions), precision bearing sets, complete gear shaft assemblies, housing gaskets, breather vents, drain and fill plugs, and oil level check plug assemblies. Parts are stocked by authorised CMN distributors in over 60 countries, enabling rapid local supply for time-critical in-season repairs. Contact your local CMN distributor or us with your gearbox serial number to ensure correct part selection.<\/p>\n<p><strong>Q: Does the T-281A fertilizer gearbox meet CE and ISO 9001 standards?<\/strong><br \/>\nA: Yes. CMN Transmission manufactures all agricultural gearboxes, including the T-281A fertilizer spreader gearbox, under an ISO 9001:2015 certified quality management system. The products carry CE marking, confirming compliance with the EU Machinery Directive. This certification is essential for OEM integrators supplying CE-marked spreading equipment to European and other markets that recognise CE as a conformity benchmark. Documentation including CE declarations and ISO certificates can be provided on request for OEM and distributor partners.<\/p>\n<p><strong>Q: Can CMN Transmission supply customised fertilizer spreader gearboxes to OEM specifications?<\/strong><br \/>\nA: Yes. CMN Transmission supports custom agricultural gearbox production based on customer-supplied drawings, 3D models, or performance specifications. Custom capabilities include: modified housing configurations for non-standard mounting geometries; non-standard shaft diameters, spline counts, or keyway profiles; special coating and surface treatment for highly corrosive applications; custom gear ratios outside the standard series range; and modified output shaft arrangements for unique implement drive layouts. Minimum order quantities apply for custom tooling; please contact the CMN engineering team with your technical requirements for a feasibility assessment and quotation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8017 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.46-1.webp\" alt=\"T-281A G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131 1.46-1\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.46-1.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.46-1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>M\u00fc\u015fteri Yorumlar\u0131<\/h2>\n<p><strong>Alejandro Martinez, Wheat and Corn Farming, Argentina<\/strong><br \/>\n\u201cPampas b\u00f6lgesinde yakla\u015f\u0131k 1400 hektarl\u0131k alanda bu\u011fday ve m\u0131s\u0131r yeti\u015ftiriyoruz.
