eje de transmisi\u00f3n de la toma de fuerza<\/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

<\/p>\n
Pasos de instalaci\u00f3n<\/h2>\n
1. Verificaci\u00f3n de seguridad previa a la instalaci\u00f3n y comprobaci\u00f3n de la longitud del eje de la toma de fuerza.<\/strong>
\nAntes de comenzar la instalaci\u00f3n, estacione el tractor en terreno nivelado, active el freno de estacionamiento, apague el motor y retire la llave de encendido. Confirme que las dimensiones del eje de la toma de fuerza (TDF) de repuesto coincidan con el di\u00e1metro del extremo de la TDF de su tractor (1 3\/4\u2033 \/ 1.750-6 estr\u00edas para BH300\/BH350). Mida la distancia desde el extremo de la TDF del tractor hasta el eje de entrada de la trituradora con el enganche en posici\u00f3n de trabajo para confirmar que la longitud del eje de la TDF de ~700 mm sea la adecuada. Verifique el rango telesc\u00f3pico para asegurar un recorrido suficiente para subir y bajar completamente el enganche sin que toque fondo ni se separe.<\/p>\n2. Engrasar todas las interfaces telesc\u00f3picas y de juntas universales.<\/strong>
\nAntes de la instalaci\u00f3n, engrase completamente la interfaz del tubo del perfil interno y todos los engrasadores de la junta universal del eje de la toma de fuerza con una grasa de litio compleja NLGI-2. El perfil telesc\u00f3pico del tubo del eje de la toma de fuerza debe engrasarse a lo largo de toda su longitud de deslizamiento para evitar el agarrotamiento bajo carga de torsi\u00f3n. Cada cruceta de la junta universal suele tener un engrasador que debe bombearse hasta que aparezca grasa nueva en el sello del cojinete. Una lubricaci\u00f3n adecuada en esta etapa es uno de los factores m\u00e1s importantes para la longevidad de la instalaci\u00f3n del eje de la toma de fuerza de un tractor.<\/p>\n3. Monte la horquilla del lado del tractor en el eje del v\u00e1stago de la toma de fuerza.<\/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 la horquilla del lado del implemento al eje de entrada de la trituradora.<\/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. Asegure la protecci\u00f3n del eje de la toma de fuerza con cadenas de anclaje.<\/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. Prueba de rodaje y verificaci\u00f3n del embrague deslizante<\/strong>
\nArranque el tractor y active la toma de fuerza (TDF) a bajas revoluciones (menos de 500 RPM) durante un ciclo de rodaje de 2 a 3 minutos. Preste atenci\u00f3n a cualquier vibraci\u00f3n, clic o golpeteo inusual que pudiera indicar una desalineaci\u00f3n, un error de fase o una conexi\u00f3n floja. Aumente gradualmente la velocidad de la TDF a 1000 RPM, controlando que el funcionamiento sea suave y sin vibraciones. Verifique que el embrague deslizante del eje de la TDF est\u00e9 correctamente ajustado mediante una prueba de sobrecarga controlada, seg\u00fan el procedimiento de ajuste del embrague FK96. Vuelva a comprobar todos los elementos de fijaci\u00f3n y los puntos de anclaje de la cadena de anclaje tras las primeras 8 a 10 horas de funcionamiento.<\/p>\n![\"Eje](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-4.webp\")
<\/p>\n
Consejos de mantenimiento para el eje de transmisi\u00f3n de la toma de fuerza<\/h2>\n
1. Inspecci\u00f3n diaria antes de cada uso.
\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. Engrase de la junta universal y del tubo telesc\u00f3pico (cada 8 horas)
\nLos cojinetes transversales de la junta universal del eje de la toma de fuerza deben engrasarse cada 8 horas de funcionamiento o una vez al d\u00eda. Aplique grasa de litio compleja NLGI-2 en cada boquilla hasta que salga grasa fresca por el sello. La interfaz del tubo de perfil telesc\u00f3pico tambi\u00e9n debe engrasarse cada 8 horas, o con mayor frecuencia en condiciones h\u00famedas o abrasivas. Extienda el tubo telesc\u00f3pico hasta la mitad, engrase la superficie interna expuesta del perfil y luego vuelva a la longitud de trabajo. Esta es la tarea de mantenimiento m\u00e1s importante para maximizar la vida \u00fatil del eje de la toma de fuerza agr\u00edcola bajo cargas pesadas de trituraci\u00f3n.<\/p>\n
3. Verificaci\u00f3n del ajuste del par del embrague deslizante (estacional)
\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. Inspecci\u00f3n del desgaste de la junta universal (cada 50 horas)
\nCada 50 horas de funcionamiento, compruebe si hay juego radial en las crucetas de la junta universal del eje de la toma de fuerza (TDF). Para ello, sujete firmemente cada horquilla y compruebe si hay movimiento perpendicular al eje de rotaci\u00f3n. Cualquier juego radial detectable indica que los cojinetes de agujas est\u00e1n desgastados y deben reemplazarse de inmediato. El funcionamiento de una junta universal desgastada a 1000 RPM con una carga de 200 a 450 HP genera calor r\u00e1pidamente y acelera su fallo. Reemplazar las crucetas de forma preventiva como parte del mantenimiento programado de las piezas del eje de la TDF es mucho menos costoso que una aver\u00eda en campo durante un proyecto de desmonte.<\/p>\n
5. Preparaci\u00f3n para el almacenamiento al final de la 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. Sustituci\u00f3n de los herrajes de protecci\u00f3n y seguridad
\nLa protecci\u00f3n del eje de la toma de fuerza (PTO) es un elemento de seguridad consumible y debe reemplazarse siempre que presente grietas, roturas o secciones faltantes. Operar sin una protecci\u00f3n completa y funcional es ilegal en la mayor\u00eda de las jurisdicciones y anula la cobertura del seguro del equipo. CMN Transmission mantiene un stock de secciones de protecci\u00f3n de repuesto, cadenas de anclaje y collares de seguridad para la horquilla. Comun\u00edquese con nuestro equipo t\u00e9cnico e ind\u00edquenos la serie y las dimensiones de su eje de toma de fuerza para obtener los componentes de protecci\u00f3n de repuesto correctos, garantizando as\u00ed que su operaci\u00f3n cumpla con la normativa y sea segura en todo momento.<\/p>\n

<\/p>\n
Soluci\u00f3n de problemas comunes<\/h2>\n
1. Vibraci\u00f3n excesiva durante el funcionamiento de la toma de fuerza.<\/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. El embrague deslizante patina con demasiada frecuencia bajo carga normal.<\/strong>
\nSi el embrague de fricci\u00f3n FK96 en el eje de la toma de fuerza del embrague deslizante patina repetidamente durante cargas normales de trituraci\u00f3n que la m\u00e1quina deber\u00eda manejar sin problemas, es probable que el paquete de resortes del embrague se haya fatigado o que un disco de fricci\u00f3n se haya vitrificado debido a sobrecargas anteriores. Confirme que el anillo de ajuste del embrague est\u00e9 correctamente posicionado para 1800 Nm en la carcasa de la serie 2500. Si el ajuste es correcto pero el deslizamiento contin\u00faa, desmonte el conjunto del embrague e inspeccione los discos de fricci\u00f3n para detectar vitrificaci\u00f3n, endurecimiento o desgaste que supere el l\u00edmite de servicio. Los discos vitrificados a veces se pueden restaurar con papel abrasivo fino; los componentes muy desgastados requieren reemplazo de la lista de piezas FK96.<\/p>\n3. El tubo telesc\u00f3pico se atasca o es dif\u00edcil de extender\/plegar.<\/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. La horquilla no se bloquea de forma segura en el extremo de la toma de fuerza.<\/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. Sobrecalentamiento de las juntas universales o de la carcasa del embrague.<\/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![\"Eje](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-12.webp\")
<\/p>\n
Eje de la toma de fuerza de la trituradora y caja de engranajes de la trituradora<\/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

Preguntas frecuentes<\/h2>\n
P: \u00bfEste eje de toma de fuerza es un reemplazo directo para la serie Walterscheid 2500 de los modelos Fecon BH300 y BH350?<\/strong>
\nS\u00ed, este eje de toma de fuerza (TDF) de la serie Walterscheid 2500 est\u00e1 dise\u00f1ado para reemplazar con precisi\u00f3n el eje de la TDF para los tractores BH300 y BH350. Todas las dimensiones cr\u00edticas, incluyendo el di\u00e1metro del eje de 1 3\/4\u2033, la especificaci\u00f3n de estr\u00edas Z20, la longitud de trabajo extendida de aproximadamente 700 mm y el conjunto de embrague FK96 con orificio de 1.750-6 estr\u00edas y un par de deslizamiento de 1800 Nm, coinciden con las especificaciones originales. Puede instalarlo directamente en el extremo de la TDF del tractor y en el eje de entrada del BH300\/BH350 sin necesidad de adaptadores, calces ni mecanizado. Si necesita confirmar las dimensiones antes de realizar el pedido, p\u00f3ngase en contacto con nuestro equipo t\u00e9cnico e ind\u00edquenos su n\u00famero de serie.<\/p>\nP: \u00bfCu\u00e1l es la longitud exacta del eje de la toma de fuerza (PTO) para los modelos Fecon BH300 y BH350, y puedo pedir una longitud personalizada?<\/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: \u00bfCu\u00e1l es la diferencia entre un eje de toma de fuerza de 540 y un eje de toma de fuerza de 1000, y cu\u00e1l requiere el 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: \u00bfCon qu\u00e9 frecuencia debo reemplazar las juntas universales del eje de la toma de fuerza en la transmisi\u00f3n del BH300\/BH350?<\/strong>
\nA: La vida \u00fatil de la junta universal depende en gran medida de la frecuencia de mantenimiento, los \u00e1ngulos de operaci\u00f3n y la intensidad de la carga. En condiciones ideales con lubricaci\u00f3n regular (cada 8 horas), las crucetas de la junta universal del eje de la toma de fuerza en una aplicaci\u00f3n de trituraci\u00f3n de 200-450 HP deber\u00edan durar entre 800 y 1500 horas de operaci\u00f3n. Sin embargo, las operaciones que impliquen terreno rocoso constante, cargas de impacto elevadas o cualquier intervalo de lubricaci\u00f3n omitido reducir\u00e1n dr\u00e1sticamente esta vida \u00fatil. Verifique la holgura radial en las crucetas cada 50 horas. Como estrategia de mantenimiento proactivo, reemplazar las crucetas de la junta universal a intervalos de 600-800 horas como mantenimiento preventivo es mucho menos costoso que una falla inesperada en el campo a mitad del proyecto. CMN Transmission tiene en stock piezas individuales del eje de la toma de fuerza para el reemplazo de las crucetas.<\/p>\nP: \u00bfSe puede ajustar el par de apriete del embrague deslizante FK96 y a qu\u00e9 par de apriete se produce el deslizamiento en los modelos 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: \u00bfCMN Transmission ofrece fabricaci\u00f3n de ejes de toma de fuerza (PTO) OEM y a medida para otros modelos de trituradoras?<\/strong>
\nA: S\u00ed. CMN Transmission opera como una empresa integrada de fabricaci\u00f3n y comercializaci\u00f3n con capacidad para producir ejes de toma de fuerza (PTO) totalmente personalizados.

Tambi\u00e9n ofrecemos suministro OEM para fabricantes de equipos con embalaje de marca privada y documentaci\u00f3n personalizada. Env\u00ede sus requisitos t\u00e9cnicos a nuestro equipo de ventas, incluyendo longitudes comprimidas y extendidas, di\u00e1metro del eje, n\u00famero de estr\u00edas, tipo de embrague y potencia nominal (HP) deseada.<\/p>\nP: \u00bfQu\u00e9 potencia (en caballos de fuerza) y especificaciones de la toma de fuerza (PTO) necesito para usar los tractores Fecon BH300 y BH350?<\/strong>
\nA: El Fecon BH300 requiere un tractor agr\u00edcola con una potencia de toma de fuerza (PTO) de 200-450 HP y un extremo de PTO trasero de 1000 RPM con estr\u00edas de 1 3\/4\u2033 (Z20). El BH350 requiere una PTO de 250-450 HP con una capacidad de PTO de 1000-1325 RPM. El tractor debe incluir una cabina cerrada con protecci\u00f3n para el operador, una transmisi\u00f3n hidrost\u00e1tica o de marcha superlenta y un enganche de 3 puntos Categor\u00eda 3 o 4 con un brazo superior hidr\u00e1ulico. Adem\u00e1s, los BH200, BH300 y BH350 requieren refrigeraci\u00f3n de la caja de cambios cuando operan por encima de 300 HP. El eje de la PTO y el extremo de la PTO de su tractor deben estar en buenas condiciones y sin desgaste detectable en las estr\u00edas antes de instalar este eje de transmisi\u00f3n de PTO de repuesto.<\/p>\nP: \u00bfQu\u00e9 causa la falla prematura del eje de la toma de fuerza en las trituradoras de uso intensivo y c\u00f3mo se puede prevenir?<\/strong>
\nA: Las causas m\u00e1s comunes de falla prematura del eje de la toma de fuerza (TDF) en aplicaciones de trituraci\u00f3n son: lubricaci\u00f3n inadecuada de los cojinetes de agujas de la junta universal y del perfil del tubo telesc\u00f3pico; operaci\u00f3n con \u00e1ngulos de junta que superan constantemente los 15 grados; sobrecargas repetidas del embrague deslizante que vitrifican los discos de fricci\u00f3n y reducen la eficacia de la protecci\u00f3n; y da\u00f1os por impacto f\u00edsico en el tubo del eje de la TDF debido a residuos. Las medidas preventivas incluyen intervalos estrictos de engrase de 8 horas, mantenimiento de la geometr\u00eda adecuada entre el tractor y el implemento, verificaci\u00f3n estacional de los ajustes del embrague deslizante, inspecci\u00f3n de da\u00f1os en el tubo despu\u00e9s de cualquier impacto con rocas o tocones, y monitoreo de la integridad del protector del eje de la TDF para garantizar que los residuos no entren en contacto con el eje giratorio.<\/p>\nP: \u00bfEste eje de toma de fuerza (PTO) tiene garant\u00eda y cu\u00e1l es la pol\u00edtica de devoluciones?<\/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: \u00bfC\u00f3mo puedo saber si necesito reemplazar el eje de la toma de fuerza (PTO) o repararlo con piezas individuales?<\/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![\"Eje](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-7.webp\")

Opiniones de los clientes<\/h2>\n
Marcus Hollingsworth, Gerente de Granja, 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, contratista de desmonte de terrenos, Australia<\/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 Forestal, 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, Alemania<\/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, empresario agr\u00edcola, Francia<\/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>\nJoao Carlos Figueiredo, empresario 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, ganadero, Nueva Zelanda<\/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, administrador de tierras de conservaci\u00f3n, Sud\u00e1frica<\/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, contratista forestal, Suecia<\/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":"\u00bfBusca un eje de toma de fuerza (PTO) de repuesto fiable y de ajuste directo para su trituradora Fecon Bull Hog BH300 o BH350?
