The CMN-SF11 Fertilizer Spreader Gearbox is purpose-built for tractor-driven fertilizer spreaders and precision seeders that demand consistent, high-torque power transmission in demanding field conditions. Running at a fixed 1:1 ratio with rated input settings of 15kW \/ 540RPM and an output torque of 265 N.m, this cast iron right-angle agricultural gearbox maintains identical input and output speed while redirecting rotational force through its compact vertical layout. The housing geometry is engineered for direct bolt-on compatibility with standard PTO-driven spreader frames, eliminating custom fabrication and reducing downtime during seasonal changeovers. Available for 8, 12, 20, and 50 cubic spreader configurations in both self-propelled and tractor-pulled drive arrangements, the SF11 scales seamlessly from small holdings to commercial arable operations covering hundreds of hectares.<\/p>\n

In operation, the gearbox transmits rotational input from the tractor PTO or hydraulic drive source to the conveyor connecting plate, which in turn drives the auger or spreading disc assembly. Organic fertilizer, granular nutrients, and soil amendments are moved through the auger channel and broadcast onto the field, directly increasing land nutrition. The CMN-SF11 fertilizer spreader gearbox suits grain farms, vegetable plots, orchards, vineyards, and large-scale pasture operations where uniform coverage, reliable uptime, and low-maintenance running costs are non-negotiable. Its construction tolerates the corrosive residues common in NPK blends and lime applications, making it a practical choice for multi-crop rotations where the spreader is run for extended periods between service intervals.<\/p>\n

Key Features of the CMN-SF11 Fertilizer Spreader Gearbox<\/h2>\n

1. Authentic German-Origin Design with Proven Reliability
\nThe CMN-SF11 gearbox for fertilizer spreaders is not a reverse-engineered approximation but a faithful execution of the original Amazone spreader gearbox design specification. Every bore diameter, mounting flange position, and spline profile is held to the same dimensional standard as the reference unit, guaranteeing drop-in fitment, correct mounting-point alignment, and full power-interface compatibility with existing spreader frames. Farmers and OEM assemblers can swap units without retooling or shimming, cutting installation time from hours to minutes.<\/p>\n

2. Optimized for High-Torque, High-Cycle Duty in Tractor-Pulled Systems
\nPurpose-designed for the high-load, high-cycle environment of PTO-driven, tractor-pulled fertilizer spreading, the CMN-SF11 agricultural gearbox excels at channeling sustained torque from the driveline to the spreading discs or auger without heat build-up or backlash. Its robust housing, cast from high-grade grey iron and stress-relieved before machining, offers exceptional resistance to the shock loads generated when crossing drainage channels, headland ridges, or rutted field tracks, delivering smooth, uninterrupted power delivery across an entire spreading pass.<\/p>\n

3. Sealed and Lubricated for Maximum Uptime in Harsh Environments
\nFertilizer residues and field dust are highly corrosive to bearing races and gear surfaces. The CMN-SF11 addresses this with a multi-layer sealing system that combines high-performance radial lip seals on both input and output shafts with close-tolerance bore fits that create a labyrinth effect against particulate ingress. Factory-filled with premium lithium-complex extreme-pressure grease rated for over 500 operating hours, the gearbox runs maintenance-free through an entire spreading season, minimizing field stops and keeping machinery available during narrow application windows.<\/p>\n

4. High-Volume Broadcast Spreading on Large-Scale Farms
\nFor large arable operations covering hundreds of acres per season, the CMN-SF11 spreader gearbox provides the rated torque capacity and structural durability to keep high-volume twin-disc spreaders running at full output day after day. Its 15kW continuous rating at 540RPM PTO speed means there is headroom for variable field conditions without throttling back the tractor, sustaining full spread width and pattern uniformity even when working at maximum hopper capacity across extended field runs.<\/p>\n

5. Precision Nutrient Management in Variable-Rate Application Systems
\nModern precision farming operations rely on GPS-guided Variable Rate Technology controllers to adjust application rates on the go. The CMN-SF11 fertilizer gearbox supports this workflow by delivering immediate torque response with negligible rotational lag, ensuring that rate changes commanded by the VRT controller translate directly into changes at the spreading disc rather than being absorbed by driveline compliance. This precision enables targeted fertilization across distinct soil-management zones within a single field, reducing input costs and maximising crop yield potential per hectare.<\/p>\n

6. Reliable Performance on Challenging and Uneven Terrain
\nOrchards, vineyards, rolling pastures, and hill-country paddocks expose spreading equipment to continuous slope changes, lateral tilt, and variable ground speed. The CMN-SF11 fertiliser spreader gearbox is built for exactly these conditions: its hardened bevel gears maintain full tooth contact under angular deflection, while the shock-resistant housing absorbs the vibration impulses generated by uneven ground. Material flow to the discs or auger remains steady regardless of terrain undulation, giving uniform coverage even on contoured land and reducing the risk of nutrient banding or missed strips.<\/p>\n

\"CMN-SF11<\/p>\n

How Does the CMN-SF11 Fertiliser Spreader Gearbox Work<\/h2>\n

The CMN-SF11 Fertilizer Spreader Gearbox is the mechanical bridge between the tractor power plant and the fertilizer distribution assembly. When the operator engages the PTO at 540RPM, that rotational input travels down the driveline and enters the gearbox through the input shaft, which is splined or keyed to accept standard agricultural driveshafts. Inside the housing, the input shaft drives a matched pair of high-precision bevel gears that redirect the rotational axis from the horizontal plane of the PTO shaft to the vertical plane of the spreading mechanism. Because the CMN-SF11 operates at a fixed 1:1 ratio, the output shaft turns at the same 540RPM as the input, maintaining a torque output of 265 N.m to suit the load demands of large-disc spreaders and hydraulically assisted auger systems.<\/p>\n

In hydraulic-drive seeder configurations, the gearbox transmits rotational power to a hydraulic pump or hydraulic motor interface rather than directly to a disc or auger shaft. The pump generates flow that drives the conveyor plate motor, which in turn moves the fertilizer or seed along the feed channel toward the auger. The auger then meters material into the broadcast stream and distributes it laterally across the intended spread width. The rate at which material is metered depends on auger geometry, hopper gate opening, and ground speed rather than on the gearbox ratio itself, meaning the CMN-SF11 gearbox serves as a constant-speed, constant-torque power source that the downstream metering system can work against reliably.<\/p>\n

In tractor-pulled PTO-driven twin-disc spreaders, the gearbox output connects directly to the spinning disc shaft or, in some designs, to an intermediate gearbox that provides speed differentiation between left and right discs for border spreading. The SF11 is sized to handle the combined disc inertia and fertilizer-impact torque spikes that occur when coarse granule materials strike the vane faces at high disc speed. Its gear geometry and housing rigidity ensure that these torque spikes are absorbed internally rather than transferred back into the PTO shaft, protecting both the tractor and the driveline from premature fatigue.<\/p>\n

For self-propelled spreader variants, where the drive source is an on-board diesel or electric power unit rather than a tractor PTO, the CMN-SF11 input shaft accepts power from a belt-drive or direct-coupled motor at the same 540RPM operating point. The mechanical interface and all downstream functions remain identical to the tractor-pulled configuration, confirming that the gearbox can be shared across spreader platforms without modification, simplifying parts inventory for distributors and service workshops.<\/p>\n

Throughout operation, the internal bearing arrangement carries both the radial loads from disc or auger reaction forces and the axial loads generated by the bevel gear tooth-engagement geometry. Both shaft seats are fitted with deep-groove ball bearings selected to handle combined loading at the rated duty cycle without lubrication breakdown. The result is a fertilizer spreader gearbox that integrates smoothly into any spreading system, coordinates reliably with tractor power source, shaft connection geometry, working load variation, and spreading mechanism design, and that a field technician can replace in under an hour using standard hand tools.<\/p>\n

In livestock farming, pasture productivity directly determines carrying capacity and animal performance. Applying urea, DAP, or lime blends across grazing paddocks with the correct spread pattern prevents the uneven sward growth and selective grazing that depletes paddock condition over time. The CMN-SF11 spreader gearbox maintains consistent disc speed across the full spread width so that granule trajectory and pattern uniformity remain stable regardless of paddock slope or terrain roughness.<\/p>\n<\/div>\n

Vegetable crops have narrow tolerance bands for nutrient concentration: too little suppresses growth, too much causes tip burn, soil salinity build-up, or nitrogen toxicity. The responsive torque delivery of the CMN-SF11 supports controlled, low-volume spread passes that keep application rates within agronomic targets for leafy greens, brassicas, alliums, and root vegetables on both open-field beds and raised-row systems.<\/p>\n

Tree and vine root systems are sensitive to localized nutrient hot spots caused by inaccurate spreading. The CMN-SF11 fertilizer spreader gearbox supports low-rate, precision application around individual root zones in orchard and vineyard inter-rows, where the spreader must also contend with uneven ground, irrigation furrows, and tight turning radiuses at row ends. Consistent torque output from the gearbox keeps disc speed stable through these manoeuvres, maintaining pattern accuracy right to the headland.<\/p>\n<\/div>\n

\n

Meyve Yeti\u015ftiricili\u011fi<\/h3>\n

Fruit crops including stone fruit, pome fruit, and tropical varieties require targeted fertility programs throughout the season, from pre-bloom nitrogen applications to post-harvest potassium and calcium treatments. The compact geometry of the CMN-SF11 agricultural gearbox for fertilizer spreaders makes it compatible with tractor-mounted spreader attachments that work between tree rows or alongside perennial plantings without clearance issues.<\/p>\n<\/div>\n<\/div>\n

\n

Soil Amendment Application<\/h3>\n

Agricultural lime, gypsum, dolomite, and biochar are typically heavier and coarser than fertilizer granules, placing higher impact loads on the spreading disc and the gearbox driving it. The CMN-SF11’s robust bevel gears and reinforced housing are rated for the higher torque spikes generated by spreading these dense materials, making it a dependable drive unit for soil pH correction and organic matter programmes that run independently of, or alongside, the main fertilizer schedule.<\/p>\n<\/div>\n

\"G\u00fcbre<\/p>\n

Operating Instructions<\/h2>\n

1. Pre-Operation Visual and Mechanical Check
\nBefore each spreading session, walk around the spreader and inspect the gearbox housing for cracks, impact damage, or visible grease loss around the shaft seals. Confirm that all four mounting bolts are torqued to the manufacturer’s specified value; loose bolts allow micromovement that scores the flange face and allows moisture ingress over time. Check that the PTO driveshaft guard is intact and that the shaft-to-gearbox coupling is fully seated and locked. Any defects found should be resolved before the tractor is started.<\/p>\n

2. Correct PTO Connection and Low-Speed Engagement
\nAttach the driveshaft to the tractor’s 540RPM PTO stub and verify that the quick-release locking collar has engaged with an audible click. When starting from cold or after a prolonged storage period, engage the PTO at a low engine RPM (approximately 800 to 900 RPM at the tractor crankshaft) while the tractor is stationary. This allows the grease inside the CMN-SF11 g\u00fcbre serpme makinesi di\u015fli kutusu<\/strong><\/a> to warm up and flow before full torque is applied, preventing cold-start shock loads on the bevel gears and bearing races.<\/p>\n

3. In-Field Start-Up and Speed Ramp-Up
\nOnce the tractor is moving and the headland has been cleared, gradually increase engine speed to bring the PTO to its rated 540RPM. Allow the spreader discs or auger to reach full operating speed before opening the hopper gate or activating the hydraulic drive conveyor. Gradual ramp-up prevents the inertia shock that can strip gear teeth or damage shaft keyways in the fertilizer spreader gearbox parts when a fully loaded hopper is engaged at full disc speed simultaneously with hopper opening.<\/p>\n

4. Mid-Session Monitoring for Abnormal Signs
\nDuring spreading passes, periodically check for unusual noise from the gearbox area, including high-pitched whining that may signal a failing bearing, or rattling that may indicate a loose fastener or driveshaft joint wear. Increased operating temperature felt at the housing during a brief hand-check (with the PTO disengaged) can indicate insufficient lubrication or overloading. Addressing these early warnings promptly avoids the unplanned downtime that comes from a gearbox failure mid-field during a narrow weather window.<\/p>\n

5. Correct PTO Disengagement at End of Pass
\nAt headlands and when the hopper is empty, disengage the PTO before dropping tractor speed below the minimum RPM at which the spreader discs remain stable. Sudden PTO disengagement at full engine RPM creates a reverse torque spike in the driveline as the disc inertia drives back through the gearbox against the braking resistance of the stalled input shaft. Where possible, reduce engine RPM to idle before disengaging the PTO clutch, allowing the rotational energy to dissipate gradually through the gearbox internals.<\/p>\n

6. Post-Use Cleaning and Corrosion Prevention
\nFertilizer residues left on the gearbox housing surface are hygroscopic and accelerate corrosion of cast iron, fastener threads, and seal housing bores. After each spreading session, use a water jet or compressed air to remove accumulated fertilizer from all external surfaces of the gearbox, paying particular attention to the area around the shaft exits where fertilizer dust packs against the lip seal faces. Dry the surface and apply a light coat of corrosion-inhibiting spray to bare metal areas if the spreader will be stored for more than a week between uses.<\/p>\n

\"CMN-SF10<\/p>\n

How to Select the Right Gearbox for Fertilizer Spreader<\/h2>\n

1. Confirm the Power Source Specification
\nIdentify whether the spreader is driven by a tractor PTO at 540RPM or 1000RPM, a hydraulic motor, or an on-board diesel or electric power unit. The CMN-SF11 is rated for 540RPM PTO input at 15kW \/ 20HP. If your tractor operates only at 1000RPM PTO, either a different gearbox model or an intermediate speed-reducing driveshaft stage is required. Never run a 540RPM-rated gearbox at 1000RPM PTO speed as this will exceed gear and bearing surface speeds and shorten service life significantly.<\/p>\n

2. Match the Transmission Ratio to the Required Disc Speed
\nThe spreader manufacturer’s technical data sheet specifies the disc or auger shaft speed required for the intended spread width and application rate. Check that the gearbox ratio, combined with the available PTO input RPM, delivers the correct output speed. The CMN-SF11 provides a 1:1 ratio, meaning disc speed equals PTO speed. If the disc assembly requires a different shaft speed, verify whether an intermediate gearbox stage or a variable-speed gearbox model better suits the application before ordering. Fertilizer spreader gearbox ratio selection directly affects spread width accuracy.<\/p>\n

3. Verify Torque Capacity Against the Spreading Load
\nCalculate the torque demand at the gearbox output shaft based on the disc or auger load at the intended spreading rate and material density. For fertilizers heavier than standard NPK granules, such as agricultural lime or wet manure compost, the torque demand increases substantially over standard granular product ratings. The CMN-SF11 is rated at 265 N.m continuous output torque. Confirm this figure is adequate for your heaviest intended material before installation; operating a gearbox above its rated torque causes accelerated gear wear, bearing overload, and premature seal failure.<\/p>\n

4. Check Mounting Flange and Shaft Interface Dimensions
\nThe gearbox must bolt directly onto the spreader frame or gearbox mounting boss without modification. Obtain the bolt circle diameter, bolt hole count, flange face dimensions, and shaft bore profiles (diameter, keyway width, keyway depth) from the spreader’s service manual or from the existing unit being replaced. Compare these to the CMN-SF11 dimension drawing available on the product page. Dimensional mismatch at the mounting flange creates shaft misalignment that overloads the input bearing and destroys seals within a few hours of operation.<\/p>\n

5. Assess the Duty Cycle and Daily Operating Hours
\nAgricultural gearboxes for fertilizer spreaders are rated for a specific duty cycle, typically expressed as hours per day or as a continuous versus intermittent rating. A spreader that runs eight to ten hours daily at full load during a compressed spring application window places different demands on the gearbox than a unit used for one or two hours per week on a small holding. Confirm that the CMN-SF11’s rated duty cycle matches your intended operating pattern. For commercial operations with extended daily running hours, it is advisable to carry a spare unit during peak application periods to minimize potential downtime.<\/p>\n

6. Evaluate the Operating Environment and Material Compatibility
\nFertilizer types vary significantly in their corrosive aggressiveness toward gearbox components. Ammonium nitrate solutions and liquid UAN are highly corrosive to bare iron and standard NBR seals. Granular urea and potassium chloride are hygroscopic and pack against seal faces in humid conditions. The CMN-SF11 cast iron housing, chemical-resistant seal materials, and corrosion-protective coating are selected for compatibility with granular and solid NPK fertilizers. If the intended material is a liquid formulation, contact CMN Transmission to confirm seal and housing material suitability before ordering.<\/p>\n

G\u00fcbre Serpme Makinesi \u015eanz\u0131man\u0131 ve PTO Tahrik Mili<\/h2>\n

The fertilizer spreader gearbox and the agricultural PTO shaft form two halves of a complete power transmission system. The PTO shaft, short for Power Take-Off shaft, is the rotating driveline component that connects the rear output stub of the tractor’s PTO mechanism to the input coupling of the spreader gearbox. It handles all of the angular compensation and length variation that occur as the tractor turns, pitches over uneven ground, and changes position relative to the trailed or mounted spreader unit. Universal joints at each end of the shaft accommodate these angular changes while maintaining continuous rotational power transfer, and the telescoping inner and outer tubes allow the shaft to extend and retract as the distance between the tractor hitch and the spreader frame changes during field work.<\/p>\n

In tractor-pulled fertilizer spreader systems, the PTO shaft delivers 540RPM rotational power from the tractor crankshaft, via the PTO clutch and reduction gearing, to the input shaft of the CMN-SF11 fertilizer spreader gearbox. The gearbox then converts that input into the correct torque magnitude and shaft direction for the spreading mechanism, whether that is a pair of spinning broadcast discs, a centrifugal impeller, or an auger-driven conveyor plate. The driveshaft must be sized in diameter, universal joint capacity, and tube wall thickness to handle the peak torque that the gearbox demands under the most demanding spreading conditions, including starting from rest with a full hopper and driving through dense, wet fertilizer that has caked on the conveyor plate.<\/p>\n

Selecting matched PTO shaft and gearbox components requires attention to several interface dimensions: the PTO stub diameter and spline count on the tractor (typically 1-3\/8 inch, 6-spline for 540RPM applications), the input shaft profile on the CMN-SF11 gearbox, the minimum and maximum operating length of the driveshaft at the extremes of the spreader’s hitch travel, and the universal joint angle rating at maximum lock-to-lock steering. Mismatched spline profiles, undersized joints, or a driveshaft that bottoms out in its telescoping tubes during tight turns are common causes of driveline failure that damage both the PTO tahrik mili<\/strong><\/a> and the gearbox input bearing. CMN Transmission’s technical team can advise on compatible PTO shaft selection for CMN-SF11 applications in any specific spreader configuration.<\/p>\n

The PTO shaft’s safety guard, a plastic or steel tube that surrounds the rotating driveshaft and is held stationary by chains attached to both the tractor and the spreader frame, is a mandatory safety requirement and must be maintained in full condition throughout the working life of the assembly. A damaged guard that contacts the rotating shaft creates friction heat that can ignite dry crop residue and lead to fire; a missing guard leaves the rotating shaft exposed and creates a serious entanglement hazard for the operator and any bystanders. CMN Transmission supplies replacement driveshafts and guard assemblies as part of its agricultural gearbox and PTO shaft accessories range, supporting complete driveline maintenance from a single supplier and reducing the sourcing complexity for fleet operators and service workshops maintaining large spreader fleets.<\/p>\n\n\n\n

Flail Mower Gearbox vs. Fertilizer Spreader Gearbox<\/h2>\n

\u00c7im bi\u00e7me makinesinin \u015fanz\u0131man\u0131 nedir?<\/h3>\n

A flail mower gearbox is the central power conversion component in a PTO-driven flail mower, converting the tractor’s driveline torque into the high-speed rotational output needed to spin the rotor carrying the swinging flail blades or Y-blades that cut vegetation. These gearboxes typically step up rotor speed well above the 540RPM PTO input, using a bevel or helical gear stage to deliver the blade-tip speed required to cut woody stems and thick grass swards cleanly. The housing is manufactured from cast iron or high-pressure die-cast aluminium, with internal gear sets made from case-hardened alloy steel to withstand the sustained vibration and shock impulses generated by blade contact with stems, stones, and buried debris. Regular lubrication, typically gear oil rather than grease, is essential to manage the high operating temperatures generated by the speed-increasing gear mesh.<\/p>\n

      A fertilizer spreader gearbox, also referred to as a fertilizer distributor gearbox, is an agricultural gearbox positioned at the drive point of a tractor-mounted or tractor-pulled fertilizer spreader. It receives rotational input from the tractor’s PTO shaft at a standard 540RPM and redirects that power through a 90-degree bevel gear mesh to the horizontal spinning discs or vertical auger shafts that broadcast granular or powdered fertilizer across the field. Unlike flail mower gearboxes, fertilizer spreader gearboxes are typically designed around a fixed ratio close to 1:1, prioritising torque consistency and directional change rather than speed multiplication. They are engineered for corrosion resistance against fertilizer compounds, reliability over extended daily operating hours during spring and autumn application windows, and dimensional interchangeability with major spreader platform designs from manufacturers such as Amazone, Kverneland, and BOGBALLE.<\/p>\n

          Korea CMN Transmission Co., Ltd. was established in 2000 and is headquartered in Sandan-o, Danwon-gu, Ansan-si, Gyeonggi-do, Republic of Korea. With a workforce of over 100 factory employees dedicated to research, development, manufacturing, and global sales, CMN Transmission has grown over more than two decades into one of the most recognized specialist suppliers of agricultural gearboxes in the international market. Our products are exported to over 60 destinations worldwide, supplying OEM manufacturers, aftermarket distributors, and independent agricultural machinery dealers across every major farming region.<\/p>\n

          Our production capacity exceeds 500,000 gearbox units per year, manufactured under ISO 9001 certified quality management and CE-marked for the European market. That scale allows us to hold finished-goods inventory across our standard agricultural gearbox range and ship from stock without the long-lead custom manufacturing delays that smaller suppliers impose on buyers during peak demand periods such as pre-spring planting and pre-autumn sowing campaigns. Every gearbox leaving our facility passes through a multi-stage quality inspection sequence covering dimensional verification, gear-mesh contact pattern analysis, torque-test running, and packaging integrity review before it is cleared for dispatch.<\/p>\n

          CMN Transmission’s product range covers rotary cutter gearboxes, rotary tiller gearboxes, feed mixer gearboxes, rotary mower gearboxes, fertilizer spreader gearboxes, flail mower gearboxes, post hole digger gearboxes, round baler gearboxes, square baler gearboxes, disc mower gearboxes, center pivot irrigation gearboxes, hydraulic drive gearboxes, silage machine gearboxes, orchard sprayer gearboxes, rotary rake gearboxes, combine harvester gearboxes, grain storage gearboxes, grain transportation gearboxes, corn header gearboxes, cutting bar gearboxes, and poultry feeding gearboxes, covering close to one thousand specifications. Our complementary product lines include PTO shafts, universal joints, yokes, telescoping tubes, torque limiters, shaft covers, driveline adapters, couplings, bearings, cutting blades, drive chains, and sprockets, enabling customers to source complete power transmission assemblies from a single technically competent supplier rather than managing multiple vendors for individual components.<\/p>\n

          Our fertilizer spreader gearboxes are exported to the United States, Canada, Mexico, Brazil, Argentina, France, Germany, Italy, Spain, the United Kingdom, Russia, India, Thailand, Vietnam, Turkey, Australia, New Zealand, and dozens of additional markets, with customer relationships that span single-farm buyers seeking a single replacement unit through to large OEM contracts covering thousands of gearboxes per production year. We support custom engineering based on customer-supplied drawings and technical specifications for agricultural gearboxes, PTO shafts, and related drivetrain components, with prototype development, pre-production sample review, and series production all managed from our Korean facility.<\/p>\n

          Q: What fertilizer spreader models is the CMN-SF11 gearbox compatible with?<\/strong>
          \nA: The CMN-SF11 is dimensionally matched to the original Amazone ZA and ZA-M series fertilizer spreader gearbox specification, covering the mounting flange bolt circle, shaft bore profiles, and housing envelope dimensions. It is also confirmed compatible with a range of other European and North American twin-disc spreader platforms that use the same industry-standard right-angle gearbox mounting geometry. For specific model confirmation, contact CMN Transmission with your spreader make, model, and the dimensions from your existing unit and we will verify fitment before you order.<\/p>\n

          Q: What is the correct fertilizer spreader gearbox oil level and lubrication type for the CMN-SF11?<\/strong>
          \nA: The CMN-SF11 uses lithium-complex extreme-pressure (EP2) grease as its lubrication medium rather than gear oil, so there is no oil level dipstick or sight glass on this unit. The gearbox is factory-filled with grease during assembly and is designed to run maintenance-free for 500 operating hours under normal field conditions. Lubrication refresh is performed through the grease nipples on both bearing housings using a hand grease gun. Overfilling should be avoided, as excess grease pressurizes the seal cavity and can cause premature lip seal failure. Do not substitute gear oil for the specified grease charge.<\/p>\n

          \n“We run a 3,200-acre mixed arable operation in Iowa and replaced the gearbox on our Amazone ZA-M spreader with the CMN-SF11 last spring. The fit was perfect, no shimming required, and it bolted straight in using the same mounting hardware. We put about 480 hours on it through the spring and fall nitrogen campaigns and it hasn’t missed a beat. No leaks, no noise, and disc speed has stayed consistent right through. Good value for money compared to the dealer price on an original unit.”<\/p>\n

The housing machining is neat, the shaft diameters fit exactly, and the device runs quietly. We have worked with it for two seasons now, about 700 operating hours in total, and the first grease change showed clean grease without metal shavings. The technical support from CMN responded quickly to our inquiries. Clear purchase recommendation for European farmers who want to avoid high-priced original spare parts.”<\/p>\n

          \n“We bought 6 units of the CMN-SF11 for our fertilizer spreaders in the Pampas region. The value for money is excellent. The cast iron housings have a good finish, the seals retain the grease perfectly even when we work with urea, which is very corrosive to lower quality seals. Delivery times were met and the export packaging arrived undamaged through the Port of Buenos Aires. For distributors looking for an Amazone-compatible spare part at a competitive price, it is a very good option.”<\/p>\n

          \n“We supply agricultural spare parts to dealers across Ontario and Quebec and added the CMN-SF11 to our catalogue this year as a more affordable alternative to OEM Amazone gearboxes. Our dealer feedback after the first spring season has been very positive: no warranty claims so far on 23 units placed, and two dealers have already reordered for their autumn stock. The product ships in sturdy wooden crates which helps a lot when goods are in transit for three weeks across the Atlantic. Will be increasing our order volume for next year.”<\/p>\n

          \n“My brother and I grow soy and corn in Mato Grosso do Sul, about 1,800 hectares in total. We bought two CMN-SF11s for our fertilizer spreaders and the results were very satisfactory. The assembly was simple because the measurements are identical to the original model. What surprised us most was the sealing quality: we work in very humid climates here and even so we had no grease leaks in either unit after almost 400 hours. The customer service to close the order was attentive and the delivery time was met.”<\/p>\n

          \n“I work as a field service technician for a large agricultural contractor in Kent that operates six fertilizer spreaders through the spring application window. We switched two machines over to CMN-SF11 gearboxes this year as a trial against the OEM parts we’ve been using. Eighteen weeks into the trial, both machines have run without issue and the gearboxes are still clean with no sign of seal weep. Fitting time was actually slightly faster than the originals because the flange face finish is very flat and seats immediately without a gap. If the rest of the season goes the same way we’ll likely convert the whole fleet.”<\/p>\n

          Marco Valentini, Meyve Yeti\u015ftiricili\u011fi, \u0130talya<\/strong>
          \n“Purchased the CMN-SF11 to replace the original gearbox on our fertilizer spreader in Veneto. The build quality is good: clean casting, precise machining, and seals in perfect condition upon delivery. We have exceeded 350 hours without any problems. The cost is almost half that of the original spare part and the performance is identical. The only thing to improve would be to have assembly instructions in Italian, but the dimensional drawing on the website is clear and we managed to do everything without difficulty. Recommended.”<\/p>","protected":false},"excerpt":{"rendered":"

          The CMN-SF11 Fertilizer Spreader Gearbox is purpose-built for tractor-driven fertilizer spreaders and precision seeders that demand consistent, high-torque power transmission in demanding field conditions. Running at a fixed 1:1 ratio with rated input settings of 15kW \/ 540RPM and an output torque of 265 N.m, this cast iron right-angle agricultural gearbox maintains identical input and output speed while redirecting rotational force through its compact vertical layout. The housing geometry is engineered for direct bolt-on compatibility with standard PTO-driven spreader frames, eliminating custom fabrication and reducing downtime during seasonal changeovers.<\/p>","protected":false},"featured_media":8035,"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-8257","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\/tr\/wp-json\/wp\/v2\/product\/8257","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/comments?post=8257"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/media\/8035"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/media?parent=8257"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/product_brand?post=8257"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/product_cat?post=8257"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/tr\/wp-json\/wp\/v2\/product_tag?post=8257"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
