CMN-SF11 Gübre Serpme Makinesi Dişli Kutusu Oranı 1:1 Dökme Demir Dik Açılı 20 HP 540 RPM PTO

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.

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.

Key Features of the CMN-SF11 Fertilizer Spreader Gearbox

1. Authentic German-Origin Design with Proven Reliability
The 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.

2. Optimized for High-Torque, High-Cycle Duty in Tractor-Pulled Systems
Purpose-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.

3. Sealed and Lubricated for Maximum Uptime in Harsh Environments
Fertilizer 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.

4. High-Volume Broadcast Spreading on Large-Scale Farms
For 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.

5. Precision Nutrient Management in Variable-Rate Application Systems
Modern 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.

6. Reliable Performance on Challenging and Uneven Terrain
Orchards, 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.

How Does the CMN-SF11 Fertiliser Spreader Gearbox Work

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.

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.

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.

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.

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.

Uygulama Senaryoları

Operating Instructions

1. Pre-Operation Visual and Mechanical Check
Before 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.

2. Correct PTO Connection and Low-Speed Engagement
Attach 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 gübre serpme makinesi dişli kutusu to warm up and flow before full torque is applied, preventing cold-start shock loads on the bevel gears and bearing races.

3. In-Field Start-Up and Speed Ramp-Up
Once 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.

4. Mid-Session Monitoring for Abnormal Signs
During 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.

5. Correct PTO Disengagement at End of Pass
At 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.

6. Post-Use Cleaning and Corrosion Prevention
Fertilizer 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.

How to Select the Right Gearbox for Fertilizer Spreader

1. Confirm the Power Source Specification
Identify 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.

2. Match the Transmission Ratio to the Required Disc Speed
The 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.

3. Verify Torque Capacity Against the Spreading Load
Calculate 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.

4. Check Mounting Flange and Shaft Interface Dimensions
The 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.

5. Assess the Duty Cycle and Daily Operating Hours
Agricultural 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.

6. Evaluate the Operating Environment and Material Compatibility
Fertilizer 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.

Gübre Serpme Makinesi Şanzımanı ve PTO Tahrik Mili

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.

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.

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 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.

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.

Flail Mower Gearbox vs. Fertilizer Spreader Gearbox

Çim biçme makinesinin şanzımanı nedir?

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.

Çim biçme makinelerinin şanzımanlarının avantajları

• High Blade-Tip Speed: The speed-increasing ratio delivers the rotor RPM needed for clean, mulched cuts on tough vegetation including brambles, saplings, and rank grass, without requiring a higher-speed PTO source on the tractor.
• Shock Absorption Tolerance: Flail mower gearbox housings and gear sets are designed to absorb repeated impact shock from blade strikes on hidden stones, soil mounds, and woody root crowns, protecting the tractor PTO shaft from fatigue failure.
• Wide Application Coverage: From roadside vegetation management and orchard floor clearing to paddock renovation and amenity grass cutting, a single flail mower gearbox type can drive equipment across a broad range of cutting tasks.
• Compact Power Density: Gear-driven speed increase within a compact housing allows a relatively low PTO torque input to generate the blade tip speed of a much larger direct-drive system, enabling compact tractor use on wide mower bodies.

• Roadside and Verge Management: Local authorities and road contractors use flail mowers driven by these gearboxes to cut back roadside vegetation, control sight lines, and maintain drainage channels.
• Orchard and Vineyard Floor Maintenance: Between-row grass and weed management in perennial crop systems relies on flail mowers to mulch cuttings in place rather than raking and removing them.
• Paddock Renovation and Weed Control: Rank pastures containing docks, thistles, and bracken are topped with flail mowers to weaken weed populations and allow grass sward recovery without chemical inputs.

Gübre Serpme Makinesi Şanzımanı Nedir?

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.

Gübre Serpme Makinesi Dişli Kutularının Avantajları

• Consistent Torque Output: A fixed 1:1 ratio ensures that disc speed and spread pattern remain stable across the full application pass, eliminating the nutrient banding that occurs when disc speed fluctuates.
• Corrosion-Resistant Construction: Cast iron housings with chemical-resistant shaft seals and corrosion-protective coatings tolerate continuous contact with NPK granules, urea, ammonium nitrate, and lime that would degrade lighter materials quickly.
• Low Maintenance Intervals: Factory grease fills rated for 500-plus operating hours reduce in-season servicing requirements, keeping the spreader productive throughout the narrow application window.
• Platform Interchangeability: Dimensional compatibility with multiple spreader platform designs from leading European and North American manufacturers makes aftermarket replacement straightforward without custom engineering.

Gübre Serpme Makinesi Dişli Kutularının Uygulamaları

• Broad-Acre Cereal Farming: Driving the twin-disc spreading mechanism on large trailed spreaders covering high-acreage fields in a single pass during pre-sowing or top-dressing campaigns.
• Precision Variable-Rate Application: Supporting GPS-guided controllers that adjust disc speed and application rates in real time based on field prescription maps for economically efficient nutrient placement.
• Lime and Soil Amendment Spreading: Providing the robust torque output needed to drive discs spreading heavier, coarser amendment materials such as agricultural lime and granulated gypsum at commercial rates.

Sıkça Sorulan Sorular

Q: What fertilizer spreader models is the CMN-SF11 gearbox compatible with?
A: 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.

Q: What is the correct fertilizer spreader gearbox oil level and lubrication type for the CMN-SF11?
A: 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.

S: CMN-SF11 gübre serpme makinesinin dişli kutusu oranı nedir ve değiştirilebilir mi?
A: CMN-SF11, sabit 1:1 aktarım oranında çalışır; bu, çıkış milinin giriş miliyle aynı hızda döndüğü ve standart 540 RPM PTO'ya bağlandığında serpme diskine 540 RPM devir sağladığı anlamına gelir. Bu oran, gövde içindeki eşleştirilmiş konik dişli seti tarafından belirlenir ve sahada ayarlanamaz. Serpme makinenizin tasarımı farklı bir çıkış hızı veya değişken hız aralığı gerektiriyorsa, farklı bir şanzıman modeli gerekecektir. CMN Transmission, standart dışı oran gereksinimleri için talep üzerine özel konfigürasyonlar sunmaktadır.

S: CMN-SF11, 1000 RPM PTO'lu bir traktörde kullanılabilir mi?
A: Hayır. CMN-SF11 gübre serpme makinesi şanzımanı, özellikle 15kW / 20HP'de 540 RPM PTO girişi için derecelendirilmiştir. Bu üniteyi 1000 RPM PTO çıkışında çalıştırmak, konik dişlilerin nominal yüzey hızını ve yatak DN değerini aşarak kısa sürede hızlandırılmış aşınmaya ve aşırı ısınmaya neden olacaktır. Traktörünüz yalnızca 1000 RPM PTO sunuyorsa, ya 1000-540 RPM adaptör mili kullanmalı ya da 1000 RPM giriş için derecelendirilmiş bir şanzıman modeli seçmelisiniz. Ekipmanı nominal hızının üzerinde kullanmak ayrıca ürün garantisini geçersiz kılar.

"Iowa'da 3.200 dönümlük karma bir tarım işletmesi yürütüyoruz ve geçen bahar Amazone ZA-M gübre serpme makinemizin şanzımanını CMN-SF11 ile değiştirdik. Mükemmel uyum sağladı, herhangi bir ayarlama gerekmedi ve aynı montaj donanımı kullanılarak doğrudan yerine takıldı. İlkbahar ve sonbahar azot uygulama kampanyaları boyunca yaklaşık 480 saat kullandık ve hiç sorun yaşamadık. Sızıntı yok, gürültü yok ve disk hızı baştan beri tutarlı kaldı. Orijinal ünitenin bayi fiyatına kıyasla paranın karşılığını fazlasıyla veriyor."

Hans-Georg Wagner, Sebze Tarımı, Almanya
"Kverneland gübre serpme makinemiz için CMN-SF11 sipariş ettik ve kalitesinden çok olumlu bir şekilde etkilendik. Gövde işçiliği düzgün, şaft çapları tam uyuyor ve cihaz sessiz çalışıyor. İki sezondur, toplamda yaklaşık 700 çalışma saatiyle kullanıyoruz ve ilk yağ değişiminde metal talaşı olmadan temiz yağ elde ettik. CMN'nin teknik desteği sorularımıza hızlı bir şekilde yanıt verdi. Yüksek fiyatlı orijinal yedek parçalardan kaçınmak isteyen Avrupalı ​​çiftçiler için kesinlikle satın alma tavsiyesi."

Darren Kelly, Mera ve Hayvancılık Yönetimi, Avustralya
"Queensland'da 900 hektarlık bir koyun ve sığır çiftliğini yönetiyorum ve yılda iki kez tüm araziye kireç ve süper fosfat serpiyoruz. Römorklu serpme makinemizin orijinal şanzımanı kırkım sırasında arızalandı ve acilen bir yedek parçaya ihtiyacım vardı. CMN, siparişten 11 gün sonra bana ulaştırdı, dürüst olmak gerekirse bunu beklemiyordum. Web sitesindeki boyut çizimini kullanarak yaklaşık 45 dakikada kendim monte ettim. Kurulumdan bu yana 14 ay geçti ve her şeyi sertleştiren oldukça iri taneli kireç serptikten sonra bile hala mükemmel çalışıyor."

Arnaud Bernard, Tahıl Tarımı, Fransa
"Bu şanzımanı Paris Havzası'ndaki gübre serpme makinemizde iki sezondur kullanıyoruz. Başlangıçta, Avrupa yapımı bir makine için Asya menşeli bir parça satın almak konusunda biraz şüpheciydim, ancak boyutlar gerçekten orijinaliyle aynı. 1:1 oranı sabit, 600 saatten sonra bile konik dişlilerde fark edilebilir bir boşluk yok ve contalar kusursuz, sızıntı yok. Müşteri hizmetleri teknik e-postalarıma 24 saatten kısa sürede yanıt verdi. Tereddüt etmeden tekrar sipariş veririm."

Santiago Rodriguez, Tarım Makineleri, Arjantin
"Pampas bölgesindeki gübre serpme makinelerimiz için 6 adet CMN-SF11 satın aldık. Fiyat performans oranı mükemmel. Dökme demir gövdeler iyi bir yüzeye sahip, contalar, düşük kaliteli contalar için oldukça aşındırıcı olan üre ile çalışırken bile gresi mükemmel şekilde tutuyor. Teslimat sürelerine uyuldu ve ihracat ambalajı Buenos Aires Limanı'ndan hasarsız bir şekilde ulaştı. Rekabetçi bir fiyata Amazone uyumlu yedek parça arayan distribütörler için çok iyi bir seçenek."

Patrick Mitchell, Tarım Parçaları, Kanada
"Ontario ve Quebec genelindeki bayilere tarım yedek parçaları tedarik ediyoruz ve bu yıl kataloğumuza OEM Amazone şanzımanlarına daha uygun fiyatlı bir alternatif olarak CMN-SF11'i ekledik. İlk bahar sezonundan sonra bayilerimizden aldığımız geri bildirimler çok olumlu: Şimdiye kadar sipariş edilen 23 ünitede hiçbir garanti talebi olmadı ve iki bayi sonbahar stokları için yeniden sipariş verdi bile. Ürün, Atlantik Okyanusu üzerinden üç hafta süren nakliye sırasında büyük fayda sağlayan sağlam ahşap kasalarda gönderiliyor. Gelecek yıl için sipariş hacmimizi artıracağız."

Rodrigo Almeida, Soya ve Mısır Tarımı, Brezilya
"Kardeşimle birlikte Mato Grosso do Sul'da toplamda yaklaşık 1800 hektarlık alanda soya ve mısır yetiştiriyoruz. Gübre serpme makinelerimiz için iki adet CMN-SF11 aldık ve sonuçlardan çok memnun kaldık. Montajı basitti çünkü ölçüler orijinal modelle aynıydı. Bizi en çok şaşırtan şey ise sızdırmazlık kalitesiydi: Burada çok nemli iklimlerde çalışıyoruz ve buna rağmen yaklaşık 400 saat sonra her iki ünitede de yağ sızıntısı yaşamadık. Siparişi tamamlamak için müşteri hizmetleri ilgiliydi ve teslimat süresi de karşılandı."

James Harrison, Meyve Bahçeleri ve Bağ Yönetimi, Birleşik Krallık
"Kent'te, ilkbahar uygulama döneminde altı gübre serpme makinesi işleten büyük bir tarım müteahhit firmasında saha servis teknisyeni olarak çalışıyorum. Bu yıl, kullandığımız orijinal parçalara karşı bir deneme olarak iki makineyi CMN-SF11 şanzımanlarına geçirdik. Denemenin 18. haftasında, her iki makine de sorunsuz çalıştı ve şanzımanlar hala temiz, conta sızıntısı belirtisi yok. Montaj süresi aslında orijinal parçalara göre biraz daha hızlıydı çünkü flanş yüzeyi çok düzgün ve boşluk bırakmadan hemen yerine oturuyor. Sezonun geri kalanı da aynı şekilde devam ederse, muhtemelen tüm filoyu dönüştüreceğiz."

Marco Valentini, Meyve Yetiştiriciliği, İtalya
"Veneto'daki gübre serpme makinemizin orijinal şanzımanını değiştirmek için CMN-SF11'i satın aldık. Üretim kalitesi iyi: temiz döküm, hassas işleme ve teslimatta contalar mükemmel durumda. 350 saati aşkın süredir sorunsuz kullanıyoruz. Maliyeti orijinal yedek parçanın neredeyse yarısı ve performansı aynı. Geliştirilebilecek tek şey, montaj talimatlarının İtalyanca olması olurdu, ancak web sitesindeki boyut çizimi açık ve her şeyi zorlanmadan hallettik. Tavsiye ederim."
