eixo de acionamento da tomada de for\u00e7a<\/strong><\/a> for mulcher applications begins at the tractor’s rear PTO stub. The tractor’s engine drives a gearbox-reduction output shaft that rotates at either 540 RPM (for lighter-duty implements) or 1000 RPM for high-horsepower PTO applications like the Fecon BH300 and BH350. The BH350’s advanced gearbox allows PTO speeds up to 1325 RPM for elevated rotor tip speed. When the operator engages the PTO clutch from inside the cab, the tractor’s PTO stub shaft begins rotating, and mechanical power is transferred through the splined yoke of the PTO shaft tractor connection point into the body of the driveline.<\/p>\nOnce engaged, torque flows from the tractor stub through the first PTO shaft yoke and into the universal joint cross-and-bearing assembly. The PTO shaft universal joint is designed to transmit rotational torque through an angular offset, allowing the driveline to operate even when the mulcher’s 3-point hitch lowers or raises the attachment relative to the tractor, or when traversing uneven ground where pitch angle changes. From the first universal joint, torque enters the inner profile tube, which slides within the outer profile of the PTO shaft tube assembly. This telescoping mechanism – engineered to allow axial extension and compression of approximately 150-200 mm – is critical for accommodating the positional change of the Bull Hog attachment as the tractor’s hydraulic top link adjusts or terrain undulations vary the hitch geometry. Heavy grease packing in the telescoping interface prevents fretting corrosion and keeps sliding resistance low even under full torque load.<\/p>\n
The FK96 friction clutch integrated into this PTO shaft with slip clutch design is perhaps its most critical protective component. During normal mulching operation, the clutch pack is held in engagement by a calibrated spring pack set to the rated 1800 Nm slip torque. Torque flows freely from the tractor side of the clutch through the friction discs and drive plates to the implement-side yoke. However, the instant a shock load event occurs – such as the rotor striking a buried rock, a large hardwood stump, or a sudden jam in the material flow – the instantaneous torque spike exceeds 1800 Nm. At this threshold, the spring pack compresses, allowing the friction discs to slip relative to the drive plates. Energy is dissipated as heat through the friction interface rather than being transmitted as a destructive shock spike into either the tractor’s PTO gearbox and transmission or the mulcher’s main gearbox. The over-running feature also allows the high-inertia rotor to continue spinning briefly after the tractor PTO is disengaged, preventing back-torque from being transmitted to the tractor driveline as rotor momentum decays. This is especially important on the heavy BH300 (7,850 lbs) and BH350 (8,200 lbs) where rotor inertia is substantial.<\/p>\n
After passing through the clutch assembly and the second telescoping tube section, torque arrives at the implement-side universal joint and yoke. The implement yoke connects directly to the input shaft of the Fecon Bull Hog’s main right-angle gearbox, which multiplies rotor shaft speed from the 1000 RPM PTO input to the high-RPM needed for rotor tip speed. The gearbox output drives the fixed-tool HDT step-rotor carrying 48 tungsten carbide cutting tools arranged in a staggered, stepped pattern. These tools impact vegetation at high velocity, shredding material into fine mulch that is returned directly to the soil. The PTO driveline shaft must maintain smooth, vibration-free operation throughout, as any imbalance or misalignment at this HP level would rapidly fatigue the universal joint bearings and shorten service life. CMN Transmission’s precision-balanced custom PTO shaft production process ensures this standard is met on every unit shipped.<\/p>\n

Etapas de instala\u00e7\u00e3o<\/h2>\n
1. Verifica\u00e7\u00e3o de seguran\u00e7a pr\u00e9-instala\u00e7\u00e3o e verifica\u00e7\u00e3o do comprimento do eixo da tomada de for\u00e7a (TDF)<\/strong>
\nAntes de iniciar a instala\u00e7\u00e3o, estacione o trator em terreno plano, acione o freio de estacionamento, desligue o motor e retire a chave da igni\u00e7\u00e3o. Confirme se as dimens\u00f5es do eixo da tomada de for\u00e7a (TDF) de substitui\u00e7\u00e3o correspondem ao di\u00e2metro do eixo da TDF do seu trator (1 3\/4\u2033 \/ 1,750-6 estrias para BH300\/BH350). Me\u00e7a a dist\u00e2ncia do eixo da TDF do trator at\u00e9 o eixo de entrada do triturador com o engate na posi\u00e7\u00e3o de trabalho para confirmar se o comprimento do eixo da TDF de aproximadamente 700 mm \u00e9 adequado. Verifique o curso telesc\u00f3pico para garantir que seja suficiente para elevar e abaixar totalmente o engate sem atingir o limite ou se soltar.<\/p>\n2. Lubrifique todas as interfaces das juntas telesc\u00f3picas e universais.<\/strong>
\nAntes da instala\u00e7\u00e3o, lubrifique abundantemente a interface do tubo do perfil interno e todos os bicos de lubrifica\u00e7\u00e3o da junta universal do eixo da tomada de for\u00e7a (TDF) usando graxa de complexo de l\u00edtio NLGI-2. O perfil telesc\u00f3pico do tubo do eixo da TDF deve ser lubrificado em toda a sua extens\u00e3o deslizante para evitar travamento sob carga de torque. Cada cruzeta da junta universal normalmente possui um bico de lubrifica\u00e7\u00e3o que deve ser bombeado at\u00e9 que graxa fresca apare\u00e7a na veda\u00e7\u00e3o do rolamento. A lubrifica\u00e7\u00e3o adequada nesta etapa \u00e9 um dos fatores mais importantes para a longevidade da vida \u00fatil dos eixos da TDF de um trator.<\/p>\n3. Monte o garfo lateral do trator no eixo curto da tomada de for\u00e7a (TDF).<\/strong>
\nAlign the PTO shaft yoke on the tractor side with the PTO stub shaft, matching the Z20 spline engagement. Slide the yoke fully onto the stub until the quick-lock collar clicks into the groove on the PTO stub, or tighten the pinch bolt to the manufacturer’s specified torque if a bolt-type collar is used. Pull the yoke rearward firmly to confirm positive engagement. Confirm that the lock pin or collar is fully seated – a loose tractor-side PTO shaft adapter connection is a leading cause of driveline vibration and premature bearing failure.<\/p>\n4. Conecte o garfo lateral do implemento ao eixo de entrada do triturador.<\/strong>
\nWith the BH300 or BH350 attached to the tractor’s 3-point hitch and the hydraulic top link connected, lower the hitch to working height. Slide the implement-side yoke of the PTO drive shaft for mulcher onto the Bull Hog’s main gearbox input stub. Engage the quick-lock or tighten the pinch bolt. Confirm phasing – on standard cardan shaft arrangements, both yokes should be in the same rotational plane (0 degrees phase offset) to minimize velocity variation through the double universal joint system and prevent cyclic vibration at speed.<\/p>\n5. Prenda a prote\u00e7\u00e3o do eixo da tomada de for\u00e7a com correntes de ancoragem.<\/strong>
\nOnce both yoke connections are confirmed, attach the PTO shaft guard anchor chains to fixed non-rotating points – one chain near the tractor hitch frame and one chain to a bracket on the Bull Hog body. The chains must have enough slack to allow articulation through the full hitch travel range but must prevent the guard from rotating with the shaft. Confirm the guard is intact, with no cracks, missing sections, or open seams before starting the tractor. CE and OSHA safety compliance requires an undamaged guard for every operational cycle.<\/p>\n6. Teste de amaciamento e verifica\u00e7\u00e3o da embreagem deslizante<\/strong>
\nLigue o trator e acione a tomada de for\u00e7a (TDF) em marcha lenta baixa (abaixo de 500 RPM) por um per\u00edodo de amaciamento de 2 a 3 minutos. Preste aten\u00e7\u00e3o a qualquer vibra\u00e7\u00e3o incomum, estalos ou batidas que possam indicar desalinhamento, erro de fase ou conex\u00e3o solta. Aumente gradualmente a rota\u00e7\u00e3o da TDF para 1000 RPM, monitorando o funcionamento para garantir uma opera\u00e7\u00e3o suave e sem vibra\u00e7\u00f5es. Verifique se a embreagem deslizante do eixo da TDF est\u00e1 ajustada corretamente, realizando um teste de sobrecarga controlada de acordo com o procedimento de ajuste da embreagem FK96. Verifique novamente todos os fixadores e pontos de fixa\u00e7\u00e3o da corrente de ancoragem ap\u00f3s as primeiras 8 a 10 horas de opera\u00e7\u00e3o.<\/p>\n![\"Eixo](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-4.webp\")
<\/p>\n
Dicas de manuten\u00e7\u00e3o para o eixo de transmiss\u00e3o da tomada de for\u00e7a (PTO)<\/h2>\n
1. Inspe\u00e7\u00e3o di\u00e1ria antes de cada utiliza\u00e7\u00e3o
\nBefore each work session, visually inspect the entire PTO shaft guard for cracks, missing sections, or damage. Verify that both anchor chains are secured and have appropriate slack. Check that the yoke quick-lock collars are fully engaged on both tractor stub and mulcher input shaft. Inspect visible portions of the PTO shaft tubing for dents, bends, or soil accumulation that could create imbalance. Address any issues found before engaging the PTO – operating with a damaged guard or improperly secured yoke creates serious safety hazards.<\/p>\n
2. Lubrifica\u00e7\u00e3o da junta universal e do tubo telesc\u00f3pico (a cada 8 horas)
\nOs mancais da junta universal do eixo da tomada de for\u00e7a (TDF) devem ser lubrificados a cada 8 horas de opera\u00e7\u00e3o ou uma vez por dia de trabalho. Utilize graxa de complexo de l\u00edtio NLGI-2 em cada bico de lubrifica\u00e7\u00e3o at\u00e9 que a graxa fresca seja expelida pela veda\u00e7\u00e3o. A interface do tubo telesc\u00f3pico tamb\u00e9m deve ser lubrificada a cada 8 horas, ou com maior frequ\u00eancia em condi\u00e7\u00f5es \u00famidas ou abrasivas. Estenda o tubo telesc\u00f3pico at\u00e9 a metade do seu comprimento, lubrifique a superf\u00edcie interna exposta do perfil e, em seguida, retorne ao comprimento de trabalho. Esta \u00e9 a tarefa de manuten\u00e7\u00e3o mais importante para maximizar a vida \u00fatil do eixo da TDF agr\u00edcola sob cargas pesadas de tritura\u00e7\u00e3o.<\/p>\n
3. Verifica\u00e7\u00e3o do ajuste de torque da embreagem deslizante (sazonal)
\nAt the start of each operating season and after any extended storage period, verify the FK96 slip clutch is still set to its rated 1800 Nm slip torque. Clutch spring sets can fatigue over time, causing slip threshold to drift lower – leading to nuisance slipping during normal operation – or higher, reducing overload protection effectiveness. Use a calibrated torque wrench setup following the FK96 adjustment procedure. If the clutch has experienced multiple severe slip events in a season, inspect the friction discs and drive plates for wear and replace if beyond the service limit.<\/p>\n
4. Inspe\u00e7\u00e3o de desgaste da junta universal (a cada 50 horas)
\nA cada 50 horas de opera\u00e7\u00e3o, verifique se h\u00e1 folga radial nas cruzetas da junta universal do eixo da tomada de for\u00e7a (TDF), segurando firmemente cada garfo e verificando se h\u00e1 movimento perpendicular ao eixo de rota\u00e7\u00e3o. Qualquer folga radial detect\u00e1vel indica desgaste dos rolamentos de agulha, que devem ser substitu\u00eddos imediatamente. Operar uma junta universal desgastada a 1000 RPM sob uma carga de 200 a 450 HP causa r\u00e1pida gera\u00e7\u00e3o de calor e falha acelerada. A substitui\u00e7\u00e3o preventiva das cruzetas, como parte da manuten\u00e7\u00e3o programada das pe\u00e7as do eixo da TDF, \u00e9 muito menos dispendiosa do que uma falha em campo durante um projeto de desmatamento.<\/p>\n
5. Prepara\u00e7\u00e3o para o armazenamento no final da temporada
\nAt the end of the operating season, thoroughly clean the entire PTO drive shaft of all accumulated soil, plant material, and moisture. Grease all nipples to full capacity to displace any moisture that may have entered bearing cavities. Extend the telescoping tube and apply a light coat of anti-corrosion grease to the exposed profile surfaces before collapsing to transport length. Store the driveline in a dry, sheltered location. Inspect the PTO shaft cover guard for UV degradation or impact damage and replace sections as needed before the next season’s use.<\/p>\n
6. Substitui\u00e7\u00e3o de prote\u00e7\u00f5es e ferragens de seguran\u00e7a
\nA prote\u00e7\u00e3o do eixo da tomada de for\u00e7a (TDF) \u00e9 um item de seguran\u00e7a consum\u00edvel e deve ser substitu\u00edda sempre que forem identificadas se\u00e7\u00f5es trincadas, quebradas ou ausentes. Operar sem uma prote\u00e7\u00e3o completa e funcional \u00e9 ilegal na maioria das jurisdi\u00e7\u00f5es e invalida a cobertura do seguro do equipamento. A CMN Transmission mant\u00e9m um estoque de se\u00e7\u00f5es de prote\u00e7\u00e3o de reposi\u00e7\u00e3o, correntes de ancoragem e an\u00e9is de seguran\u00e7a para o garfo. Entre em contato com nossa equipe t\u00e9cnica, informando a s\u00e9rie e as dimens\u00f5es do seu eixo da TDF, para obter os componentes de reposi\u00e7\u00e3o corretos da prote\u00e7\u00e3o, garantindo que sua opera\u00e7\u00e3o permane\u00e7a em conformidade e segura em todos os momentos.<\/p>\n

<\/p>\n
Solu\u00e7\u00e3o de problemas comuns<\/h2>\n
1. Vibra\u00e7\u00e3o excessiva durante a opera\u00e7\u00e3o da tomada de for\u00e7a (TDF)<\/strong>
\nVibration is most commonly caused by yoke misalignment (improper phasing), worn or seized PTO shaft universal joint needle bearings, a bent or dented PTO shaft tube section, or accumulated debris packed around the guard tube creating imbalance. Check yoke phase alignment first – both yokes must be in the same plane. Rotate the shaft slowly by hand and feel for roughness or binding at the universal joint crosses indicating bearing failure. Remove all mud and vegetation from around the guard and tube exterior. If vibration persists after addressing these items, the shaft may require professional balance inspection.<\/p>\n2. Embreagem deslizante patinando com muita frequ\u00eancia sob carga normal.<\/strong>
\nSe a embreagem de fric\u00e7\u00e3o FK96 no eixo da tomada de for\u00e7a (TDF) estiver patinando repetidamente durante cargas normais de tritura\u00e7\u00e3o que a m\u00e1quina deveria suportar sem problemas, \u00e9 prov\u00e1vel que o conjunto de molas da embreagem esteja fatigado ou que um disco de fric\u00e7\u00e3o tenha vitrificado devido a sobrecargas anteriores. Verifique se o anel de ajuste da embreagem est\u00e1 posicionado corretamente para 1800 Nm na carca\u00e7a da S\u00e9rie 2500. Se o ajuste estiver correto, mas a patina\u00e7\u00e3o persistir, desmonte o conjunto da embreagem e inspecione os discos de fric\u00e7\u00e3o quanto a vitrifica\u00e7\u00e3o, endurecimento ou desgaste al\u00e9m do limite de servi\u00e7o. Discos vitrificados podem, \u00e0s vezes, ser restaurados com lixa fina; componentes severamente desgastados exigem substitui\u00e7\u00e3o a partir da lista de pe\u00e7as FK96.<\/p>\n3. Tubo telesc\u00f3pico emperrado ou dif\u00edcil de estender\/recolher<\/strong>
\nBinding in the PTO shaft tubing telescoping interface is caused by inadequate lubrication, rust formation on the inner profile surface, or physical deformation of the tube from a side impact. Disconnect the shaft from both ends, extend fully, and inspect the inner profile surface for rust, galling, or burrs. Clean thoroughly with a wire brush, apply penetrating lubricant, and work the telescoping sections back and forth repeatedly to free the interface. Apply a generous coat of high-EP grease before reassembly. If the profile is deformed from an impact, the affected tube section must be replaced – operating a binding driveline under load causes rapid seal failure and profile galling.<\/p>\n4. O garfo n\u00e3o est\u00e1 travando firmemente no eixo da tomada de for\u00e7a.<\/strong>
\nIf the quick-lock collar on the tractor-side PTO shaft yoke fails to engage or release from the PTO stub shaft, the lock pin ball detent may be worn, the groove on the PTO stub may be damaged, or debris may be packed in the collar mechanism. Clean the collar internals and PTO stub groove thoroughly. Inspect the ball detent spring for fatigue. If the lock fails to seat positively under a pull test after cleaning, replace the yoke collar assembly immediately. Never operate a tractor PTO shaft with a yoke that is not positively locked – catastrophic separation under load at 1000 RPM is an extremely dangerous event.<\/p>\n5. Superaquecimento das juntas universais ou da carca\u00e7a da embreagem<\/strong>
\nExcessive heat from universal joint areas indicates seized needle bearings operating dry due to missed greasing intervals, or operation at joint angles consistently beyond the rated maximum. Heat from the clutch housing area typically indicates sustained slip – either from a mis-set slip torque or from operating consistently at or above the 450 HP maximum rating. Stop operation immediately if overheating is detected. Allow components to cool, check grease levels, and inspect the operating angle. For the BH300\/BH350, ensure the 3-point hitch geometry keeps the PTO driveline shaft operating angle below 15 degrees during normal working travel.<\/p>\n![\"Eixo](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-12.webp\")
<\/p>\n
Eixo da tomada de for\u00e7a do triturador e caixa de engrenagens do triturador<\/h2>\n
The mulcher PTO shaft is the mechanical backbone of any tractor-driven mulching system. It is a heavy-duty, articulated PTO driveline shaft connecting the tractor’s rear PTO output to the mulcher’s gearbox input, transmitting engine-generated torque across a variable-angle, variable-length connection. For high-horsepower mulchers like the Fecon BH300 and BH350 – which operate at 200-450 HP and weigh up to 8,200 lbs – the PTO drive shaft must be engineered for extreme load cycles, shock events, and continuous 1000 RPM operation. This means precision-machined yokes, high-strength alloy steel universal joint crosses, heavy-wall PTO shaft tube construction, and an integrated over-running friction clutch that protects both ends of the driveline from destructive torque spikes.<\/p>\n
A quality tractor PTO shaft for mulcher applications must also accommodate the significant positional variation that occurs as the 3-point hitch float follows terrain – the telescoping profile tube handles axial length change while the double universal joint system handles angular offset. The FK96 over-running clutch also permits the high-inertia rotor to coast freely after PTO disengagement, preventing damaging back-torque from being transmitted through the driveline to the tractor gearbox. Every element of the PTO shaft for Fecon Bull Hog mulcher is designed with this demanding operational profile in mind.<\/p>\n
The mulcher gearbox – sometimes called the chipper gearbox or forestry mulcher gearbox – is the mechanical interface between the PTO driveline and the cutting rotor. In the Fecon BH300 and BH350, this is a heavy-duty right-angle gearbox that accepts the 1000 RPM input from the PTO shaft and converts it to the high rotor speed required for efficient vegetation shredding. On higher-horsepower models including the BH300 series, Fecon’s patented synchronized pivoting gearbox system is incorporated to maintain constant rotor speed even as the attachment pitch angle varies during terrain following.<\/p>\n
The PTO driveline shaft for mulcher and the mulcher gearbox are inseparable partners in the power transmission chain. Without a properly functioning, correctly specified PTO shaft with slip clutch, the gearbox is exposed to uncontrolled shock loads that can fracture input shaft bearings, crack housing castings, or strip gear teeth. Without a healthy mulcher gearbox, the finest PTO drive shafts cannot deliver useful work. CMN Transmission supplies both mulcher PTO shafts and compatible mulcher gearboxes, offering operators a complete drivetrain replacement solution from a single, ISO9001-certified source – eliminating the compatibility uncertainty that can arise when sourcing components from multiple vendors. Contact our technical team to confirm the correct gearbox and PTO shaft combination for your specific Fecon Bull Hog model and tractor specification.<\/p>\n

Perguntas frequentes<\/h2>\n
P: Este eixo da tomada de for\u00e7a (PTO) \u00e9 um substituto direto para o eixo da s\u00e9rie Walterscheid 2500 nos tratores Fecon BH300 e BH350?<\/strong>
\nR: Sim, este produto foi projetado como um substituto de precis\u00e3o para o eixo da tomada de for\u00e7a (TDF) da s\u00e9rie 2500 da Walterscheid, tanto para o BH300 quanto para o BH350. Todas as dimens\u00f5es cr\u00edticas, incluindo o di\u00e2metro do eixo de 1 3\/4\u2033, a especifica\u00e7\u00e3o da estria Z20, o comprimento de trabalho estendido de aproximadamente 700 mm e o conjunto da embreagem FK96 com furo de 1,750-6 estrias e torque de deslizamento de 1800 Nm, correspondem \u00e0s especifica\u00e7\u00f5es originais. Voc\u00ea pode instal\u00e1-lo diretamente no eixo da TDF existente do trator e no eixo de entrada do BH300\/BH350 sem a necessidade de adaptadores, cal\u00e7os ou usinagem. Entre em contato com nossa equipe t\u00e9cnica informando o n\u00famero de s\u00e9rie do seu ve\u00edculo caso precise de confirma\u00e7\u00e3o dimensional antes de fazer o pedido.<\/p>\nP: Qual \u00e9 o comprimento exato do eixo da tomada de for\u00e7a (PTO) para os tratores Fecon BH300 e BH350, e posso encomendar um comprimento personalizado?<\/strong>
\nA: The standard PTO shaft length for both the BH300 and BH350 is approximately 700 mm in extended working position. However, PTO shaft dimensions can vary slightly depending on specific tractor model, hitch configuration, and any optional hydraulic top link setup. If you require a custom PTO shaft length outside the standard 700 mm, CMN Transmission offers full customization services – simply provide the required compressed and extended lengths, shaft diameter, and spline specifications, and our engineering team will produce a made-to-order PTO driveline shaft to your exact requirements.<\/p>\nP: Qual a diferen\u00e7a entre um eixo de tomada de for\u00e7a (TDF) de 540 e um eixo de TDF de 1000, e qual deles \u00e9 necess\u00e1rio para os tratores BH300\/BH350?<\/strong>
\nA: A 540 PTO shaft is designed for implements that draw less horsepower (typically under 100 HP) and uses a 1 3\/8\u2033 (6-spline) shaft that rotates at 540 RPM. A 1000 PTO shaft is designed for high-horsepower implements and uses a 1 3\/4\u2033 (20-spline) shaft that rotates at 1000 RPM – transmitting significantly more power at the same tractor engine speed. The Fecon BH300 and BH350 are high-horsepower mulchers (200-450 HP) and exclusively require a 1000 rpm PTO shaft with 1 3\/4\u2033 Z20 spline. Using an incorrect PTO shaft adapter or attempting to run a 540 RPM shaft on these mulchers would be dangerous and would immediately fail under load.<\/p>\nP: Com que frequ\u00eancia devo substituir as juntas universais do eixo da tomada de for\u00e7a (PTO) na transmiss\u00e3o do BH300\/BH350?<\/strong>
\nA: A vida \u00fatil das juntas universais depende muito da frequ\u00eancia de manuten\u00e7\u00e3o, dos \u00e2ngulos de opera\u00e7\u00e3o e da intensidade da carga. Em condi\u00e7\u00f5es ideais, com lubrifica\u00e7\u00e3o regular (a cada 8 horas), as cruzetas das juntas universais do eixo da tomada de for\u00e7a (TDF) em uma aplica\u00e7\u00e3o de tritura\u00e7\u00e3o de 200 a 450 HP devem durar de 800 a 1500 horas de opera\u00e7\u00e3o. No entanto, opera\u00e7\u00f5es que envolvam terrenos rochosos constantes, cargas de impacto elevadas ou qualquer intervalo de lubrifica\u00e7\u00e3o perdido reduzir\u00e3o drasticamente essa vida \u00fatil. Verifique a folga radial nas cruzetas a cada 50 horas. Como estrat\u00e9gia de manuten\u00e7\u00e3o proativa, a substitui\u00e7\u00e3o das cruzetas das juntas universais em intervalos de 600 a 800 horas como manuten\u00e7\u00e3o preventiva \u00e9 muito menos dispendiosa do que uma falha inesperada em campo no meio do projeto. A CMN Transmission mant\u00e9m em estoque pe\u00e7as individuais do eixo da TDF para substitui\u00e7\u00e3o das cruzetas.<\/p>\nP: \u00c9 poss\u00edvel ajustar o torque da embreagem deslizante do FK96? E qual \u00e9 o torque de deslizamento para os motores BH300\/BH350?<\/strong>
\nA: Yes, the FK96 over-running friction clutch integrated into this PTO shaft with slip clutch is adjustable via the setting ring (component #15 in the parts list). For the 2500 Series with 1.750-6 spline bore as used on the BH300 and BH350, the factory setting is 1800 Nm. This is the correct slip torque for protecting the Fecon mulcher gearbox and tractor drivetrain from shock overloads in the 200-450 HP operating range. The setting should be verified seasonally and after any significant overload event. Adjusting above or below the 1800 Nm specification without understanding the tractor and implement drivetrain’s rated maximum torque is not recommended.<\/p>\nP: A CMN Transmission oferece fabrica\u00e7\u00e3o de eixos de tomada de for\u00e7a (PTO) OEM e personalizados para outros modelos de trituradores?<\/strong>
\nR: Sim. A CMN Transmission opera como uma empresa integrada de fabrica\u00e7\u00e3o e comercializa\u00e7\u00e3o, com capacidade total de produ\u00e7\u00e3o de eixos de tomada de for\u00e7a (TDF) personalizados. Al\u00e9m da configura\u00e7\u00e3o padr\u00e3o BH300\/BH350, podemos fabricar conjuntos de eixos de acionamento da TDF para tratores com qualquer especifica\u00e7\u00e3o de tamanho, perfil de estrias, tipo de embreagem e comprimento do eixo para outros modelos Fecon Bull Hog, bem como para as marcas Mulchmaster, FAE, Seppi, Prinoth e outras de trituradores florestais. Tamb\u00e9m oferecemos fornecimento OEM para fabricantes de equipamentos, com embalagens de marca pr\u00f3pria e documenta\u00e7\u00e3o personalizada. Envie seus requisitos t\u00e9cnicos para nossa equipe de vendas, incluindo comprimentos comprimido e estendido, di\u00e2metro do eixo, n\u00famero de estrias, tipo de embreagem e pot\u00eancia (HP) desejada.<\/p>\nP: Qual a pot\u00eancia do trator e a especifica\u00e7\u00e3o do eixo da tomada de for\u00e7a (TDF) necess\u00e1rias para operar os tratores Fecon BH300 e BH350?<\/strong>
\nA: O Fecon BH300 requer um trator agr\u00edcola com pot\u00eancia na tomada de for\u00e7a (TDF) de 200 a 450 cv e um eixo traseiro da TDF de 1000 rpm com estrias de 1 3\/4\" (Z20). O BH350 requer pot\u00eancia na TDF de 250 a 450 cv e capacidade de rota\u00e7\u00e3o de 1000 a 1325 rpm. O trator deve possuir cabine fechada com prote\u00e7\u00e3o para o operador, marcha super-reduzida ou transmiss\u00e3o hidrost\u00e1tica e engate de tr\u00eas pontos de categoria 3 ou 4 com terceiro ponto hidr\u00e1ulico. Al\u00e9m disso, os modelos BH200, BH300 e BH350 requerem refrigera\u00e7\u00e3o da caixa de engrenagens quando operando acima de 300 cv. O eixo e o eixo da TDF do seu trator devem estar em boas condi\u00e7\u00f5es, sem desgaste detect\u00e1vel nas estrias, antes da instala\u00e7\u00e3o deste eixo de acionamento da TDF de reposi\u00e7\u00e3o.<\/p>\nP: O que causa a falha prematura do eixo da tomada de for\u00e7a (TDF) em trituradores de alta pot\u00eancia e como isso pode ser evitado?<\/strong>
\nA: As causas mais comuns de falha prematura do eixo da tomada de for\u00e7a (TDF) em aplica\u00e7\u00f5es de tritura\u00e7\u00e3o de solo s\u00e3o: lubrifica\u00e7\u00e3o inadequada dos rolamentos de agulha da junta universal e do perfil do tubo telesc\u00f3pico; opera\u00e7\u00e3o com \u00e2ngulos de junta consistentemente superiores a 15 graus; sobrecargas repetidas da embreagem deslizante que vitrificam os discos de fric\u00e7\u00e3o e reduzem a efic\u00e1cia da prote\u00e7\u00e3o; e danos por impacto f\u00edsico no tubo do eixo da TDF causados \u200b\u200bpor detritos. As medidas preventivas incluem lubrifica\u00e7\u00e3o a cada 8 horas, manuten\u00e7\u00e3o da geometria correta entre o trator e o implemento, verifica\u00e7\u00e3o sazonal das configura\u00e7\u00f5es da embreagem deslizante, inspe\u00e7\u00e3o do tubo ap\u00f3s impactos com pedras ou tocos e monitoramento da integridade da prote\u00e7\u00e3o do eixo da TDF para garantir que os detritos n\u00e3o entrem em contato com o eixo rotativo.<\/p>\nP: Este eixo da tomada de for\u00e7a (PTO) vem com garantia? Qual \u00e9 a pol\u00edtica de devolu\u00e7\u00e3o?<\/strong>
\nA: Yes. CMN Transmission’s agricultural PTO shaft products are backed by a product quality warranty covering manufacturing defects in materials and workmanship. Our after-sales service team provides technical support, replacement component sourcing, and warranty claim processing. In the event of a verified manufacturing defect identified within the warranty period, we will supply replacement parts or a replacement unit. Note that warranty coverage does not extend to damage caused by incorrect installation, operation beyond rated HP limits, use without the PTO shaft guard, or failure to maintain the specified lubrication intervals. Contact our after-sales team for full warranty terms applicable to your region.<\/p>\nP: Como sei se o eixo da tomada de for\u00e7a (PTO) precisa ser substitu\u00eddo ou reparado com pe\u00e7as individuais?<\/strong>
\nA: Individual PTO shaft parts replacement is cost-effective when damage is limited to specific components: a worn U-joint cross can be replaced without replacing the entire shaft; glazed friction discs in the FK96 clutch can be sourced and swapped individually; a cracked PTO shaft guard tube can be replaced in sections. Full shaft replacement becomes the better choice when the main profile tube is bent or dented (which creates permanent imbalance), when the yoke splines show significant wear that would compromise engagement, when multiple components have failed simultaneously, or when the cumulative cost of individual repairs approaches the cost of a complete replacement. CMN Transmission can advise on the most cost-effective repair-versus-replace decision for your specific situation – contact our technical team with a description of the damage.<\/p>\n![\"Eixo](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-7.webp\")

Marcus Hollingsworth, Gerente Agr\u00edcola, Estados Unidos<\/strong>
\n“Been running a BH300 on our 420 HP Case Quadtrac for about three seasons now. The original Walterscheid driveline finally wore through the U-joints last fall, and I wasn’t about to pay dealer markup for a replacement. Ordered the 2500 Series replacement from CMN Transmission – the 1.750-6 spline bore, 1800Nm clutch setting, ~700mm length. Arrived in about ten days, which I honestly wasn’t expecting for an overseas supplier. Fit was dead-on, slid straight onto the BH300 input shaft, no shimming, no adapter games. Put about 220 hours on it clearing hardwood bottomland and the thing hasn’t skipped a beat. Build quality feels every bit as solid as the Walterscheid it replaced. Will be back for another when this one wears out.”<\/p>\nDarren Mackinnon, empreiteiro de desmatamento, Austr\u00e1lia<\/strong>
\n“G’day – we run two BH350s on New Holland T9 tractors for large-scale scrub clearing in Queensland. Been sourcing spares from Europe but the lead times and freight cost were killing our job margins. Tried CMN Transmission on a mate’s recommendation. Ordered two complete PTO shaft assemblies – the 1000-1325 RPM rated units for the BH350. Quality is genuinely impressive. The slip clutch preset torque was spot-on – verified it ourselves with a torque checker before installation. Guard tubes are solid, no flex or rattle. Delivery was 12 days door to door, which for international freight into regional Queensland is excellent. Already placed a second order. Competitive pricing for the quality level on offer.”<\/p>\nKyle Tremblay, Operador Florestal, Canad\u00e1<\/strong>
\n“We use a BH300 on our forestry operation in British Columbia. Our previous PTO shaft lasted four years of hard use before a U-joint seized on us mid-job in fairly remote terrain – not a great day. When we were sourcing a replacement I reached out to CMN’s technical team to confirm the correct spline and clutch spec for our exact setup. They responded same day with the exact dimensional drawing, confirmed the 1.75-6 bore and 1800Nm setting, and had the unit shipped the following day. The technical support pre-sale was honestly what closed the deal for me. Shaft arrived in perfect condition, installed in under 45 minutes. Very happy with the product and the team behind it.”<\/p>\nStefan Breitenbacher, Forstunternehmer, Alemanha<\/strong>
\n“We operate a BH300 in our forestry business in Bavaria and urgently required a replacement of the Walterscheid 2500 PTO shaft. The CMN shaft was delivered within 14 working days, which was very acceptable given the distance. The product quality is flawless, the yoke fits snugly on the PTO stub shaft, the friction clutch engages cleanly at 1800 Nm, and the guard tube is stable. For our operation, it is a complete equivalent replacement at a significantly lower price compared to the OEM supplier. I have also recommended the product to a colleague in Saxony.”<\/p>\nThierry Morel, Empres\u00e1rio Agr\u00edcola, Fran\u00e7a<\/strong>
\n“We use two BH350s for land clearing work in Normandy. After an on-site incident in which the original cardan shaft was twisted due to an overload, we ordered a replacement from CMN Transmission. Quick response, detailed quote with all cardan parameters (1.75-6 bore, 1800 Nm setting), and delivery in 10 working days. Installation was problem-free with a perfect fit on the BH350. The quality-to-price ratio is far superior to that of our usual supplier. We will continue working with CMN for future orders.”<\/p>\nJo\u00e3o Carlos Figueiredo, Empreendedor Agr\u00edcola, Brasil<\/strong>
\n“I work with land clearing in Mato Grosso and have been using a BH300 for four years. I needed to replace the cardan shaft after approximately 1,400 hours of heavy work, which is not bad considering the usage. I purchased from CMN Transmission because a local distributor recommended it. The product arrived in 16 working days with reinforced packaging and no damage. The shaft fitted perfectly into the BH300 coupling without any adjustments. The slip clutch has been operating correctly since the first day. The price is very competitive compared to local importers who charge exorbitant amounts. I recommend it to anyone needing a quality cardan shaft without paying a fortune.”<\/p>\nHamish Gallagher, pecuarista, Nova Zel\u00e2ndia<\/strong>
\n“Running a 350-acre beef and sheep operation in the Waikato – we use a BH300 on a John Deere 8R for pasture reclamation and scrub clearing along our creek systems. Snapped a U-joint last spring during a particularly bad session on some old blackberry and gorse. Local dealer wanted an eye-watering price and a six-week lead time. Found CMN Transmission online, made contact, confirmed the exact spec with their team within a few hours. Received the complete PTO shaft assembly in nine days. Fit was perfect, zero issues. The guard tube quality is noticeably better than some aftermarket parts I’ve used in the past. Will keep CMN Transmission in mind for future parts needs.”<\/p>\nSipho Ndlovu, Gestor de Terras de Conserva\u00e7\u00e3o, \u00c1frica do Sul<\/strong>
\n“We use a BH350 for invasive bush clearing on conservation land in Limpopo. Getting the right PTO shaft parts here is always a challenge – most suppliers won’t ship to South Africa reliably, or when they do the freight cost kills the savings. CMN Transmission was completely transparent about shipping timelines – 18 working days to Polokwane, which is exactly what we received. No damage, correct product. The shaft spec was confirmed in writing before order placement with a detailed dimensional drawing – that kind of professionalism is rare with international suppliers. Product performance has been flawless through 90 hours of heavy clearing. Will definitely purchase again.”<\/p>\nAnders Lindqvist, empreiteiro florestal, Su\u00e9cia<\/strong>
\n“We use a BH300 for clearing work for utility companies in northern Sweden. The clutch housing on the original shaft cracked after a significant overload in a ditch. I found CMN Transmission via Google and contacted them in English. A response came within a few hours with the technical specification confirmed and a quote received. We ordered a complete shaft with the FK96 clutch set to 1800 Nm. Delivery took 13 working days to Sundsvall\u2014acceptable for an international order. The shaft fitted perfectly and the clutch torque appears correct. The price is approximately 40% lower than ordering through the Swedish OEM distributor. Recommended.”<\/p>","protected":false},"excerpt":{"rendered":"Procurando um eixo de tomada de for\u00e7a (TDF) confi\u00e1vel e de encaixe direto para o seu triturador Fecon Bull Hog BH300 ou BH350?
