arbre de transmission de prise de force<\/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

\u00c9tapes d'installation<\/h2>\n
1. Contr\u00f4le de s\u00e9curit\u00e9 avant installation et v\u00e9rification de la longueur de l'arbre de prise de force<\/strong>
\nAvant de commencer l'installation, garez le tracteur sur un terrain plat, serrez le frein de stationnement, coupez le moteur et retirez la cl\u00e9 de contact. V\u00e9rifiez que les dimensions de l'arbre de prise de force de remplacement correspondent au diam\u00e8tre de l'embase de prise de force de votre tracteur (1 3\/4\u2033 \/ 1,750 - 6 cannelures pour BH300\/BH350). Mesurez la distance entre l'embase de prise de force du tracteur et l'arbre d'entr\u00e9e du broyeur, l'attelage \u00e9tant en position de travail, afin de confirmer que la longueur de l'arbre de prise de force (~700 mm) est appropri\u00e9e. V\u00e9rifiez \u00e9galement la course t\u00e9lescopique pour vous assurer qu'elle est suffisante pour lever et abaisser compl\u00e8tement l'attelage sans but\u00e9e ni d\u00e9solidarisation.<\/p>\n2. Graisser toutes les interfaces t\u00e9lescopiques et de joints universels<\/strong>
\nAvant l'installation, graissez soigneusement l'interface du tube profil\u00e9 int\u00e9rieur et tous les graisseurs des joints de cardan de l'arbre de prise de force \u00e0 l'aide d'une graisse au lithium complexe NLGI-2. Le tube t\u00e9lescopique de l'arbre de prise de force doit \u00eatre graiss\u00e9 sur toute sa longueur de coulissement afin d'\u00e9viter tout grippage sous l'effet du couple. Chaque joint de cardan poss\u00e8de g\u00e9n\u00e9ralement un graisseur qu'il convient de pomper jusqu'\u00e0 ce que de la graisse fra\u00eeche apparaisse au niveau du joint d'\u00e9tanch\u00e9it\u00e9 du roulement. Une lubrification ad\u00e9quate \u00e0 cette \u00e9tape est un facteur d\u00e9terminant pour la dur\u00e9e de vie des arbres de prise de force d'un tracteur.<\/p>\n3. Montez le joug c\u00f4t\u00e9 tracteur sur l'arbre de prise de force.<\/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. Raccordez le joug c\u00f4t\u00e9 outil \u00e0 l'arbre d'entr\u00e9e du broyeur.<\/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. Fixez le protecteur d'arbre de prise de force avec des cha\u00eenes d'ancrage.<\/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. Essai de rodage et v\u00e9rification de l'embrayage \u00e0 glissement<\/strong>
\nD\u00e9marrez le tracteur et engagez la prise de force au ralenti (moins de 500 tr\/min) pendant 2 \u00e0 3 minutes pour le rodage. Soyez attentif \u00e0 toute vibration, cliquetis ou cognement anormal pouvant indiquer un d\u00e9faut d'alignement, un probl\u00e8me de phase ou une connexion desserr\u00e9e. Augmentez progressivement le r\u00e9gime de la prise de force jusqu'\u00e0 1\u00a0000 tr\/min en v\u00e9rifiant son fonctionnement r\u00e9gulier et sans vibrations. Assurez-vous que le limiteur de couple de la prise de force est correctement r\u00e9gl\u00e9 en effectuant un test de surcharge contr\u00f4l\u00e9e conform\u00e9ment \u00e0 la proc\u00e9dure de r\u00e9glage de l'embrayage FK96. Apr\u00e8s les 8 \u00e0 10 premi\u00e8res heures de fonctionnement, rev\u00e9rifiez tous les \u00e9l\u00e9ments de fixation et les points d'ancrage de la cha\u00eene.<\/p>\n![\"Arbre](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-4.webp\")
<\/p>\n
Conseils d'entretien pour l'arbre de transmission de la prise de force<\/h2>\n
1. Inspection quotidienne avant chaque utilisation
\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. Graissage du joint universel et du tube t\u00e9lescopique (toutes les 8 heures)
\nLes paliers transversaux du joint de cardan de l'arbre de prise de force doivent \u00eatre graiss\u00e9s toutes les 8 heures de fonctionnement ou une fois par jour. Utilisez une graisse au lithium complexe NLGI-2 dans chaque graisseur jusqu'\u00e0 ce que de la graisse neuve s'\u00e9coule du joint. L'interface du tube t\u00e9lescopique doit \u00e9galement \u00eatre graiss\u00e9e toutes les 8 heures, ou plus fr\u00e9quemment en conditions humides ou abrasives. D\u00e9ployez le tube t\u00e9lescopique \u00e0 mi-course, graissez la surface int\u00e9rieure expos\u00e9e du profil, puis ramenez-le \u00e0 sa longueur de travail. Il s'agit de l'op\u00e9ration de maintenance la plus importante pour optimiser la dur\u00e9e de vie de l'arbre de prise de force agricole sous fortes charges de broyage.<\/p>\n
3. V\u00e9rification du couple de r\u00e9glage de l'embrayage \u00e0 glissement (saisonnier)
\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. Inspection de l'usure des joints universels (toutes les 50 heures)
\nToutes les 50 heures de fonctionnement, v\u00e9rifiez le jeu radial des croisillons du joint de cardan de l'arbre de prise de force en les saisissant fermement et en contr\u00f4lant tout mouvement perpendiculaire \u00e0 l'axe de rotation. Tout jeu radial d\u00e9tectable indique une usure des roulements \u00e0 aiguilles, qui doivent \u00eatre remplac\u00e9s rapidement. Faire tourner un joint de cardan us\u00e9 \u00e0 1\u00a0000 tr\/min sous une charge de 200 \u00e0 450 ch provoque une forte chaleur et une usure pr\u00e9matur\u00e9e. Le remplacement pr\u00e9ventif des croisillons dans le cadre de l'entretien r\u00e9gulier des pi\u00e8ces de l'arbre de prise de force est bien moins co\u00fbteux qu'une panne sur le terrain lors de travaux de d\u00e9frichage.<\/p>\n
5. Pr\u00e9paration du stockage de fin de saison
\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. Remplacement des protections et des dispositifs de s\u00e9curit\u00e9
\nLe protecteur d'arbre de prise de force est une pi\u00e8ce d'usure et doit \u00eatre remplac\u00e9 d\u00e8s qu'il pr\u00e9sente des fissures, des cassures ou des sections manquantes. L'utilisation d'un protecteur sans dispositif de protection complet et fonctionnel est ill\u00e9gale dans la plupart des juridictions et annule la couverture d'assurance de l'\u00e9quipement. CMN Transmission dispose d'un stock de sections de protecteur de rechange, de cha\u00eenes d'ancrage et de colliers de s\u00e9curit\u00e9 pour l'\u00e9trier. Contactez notre \u00e9quipe technique en indiquant la s\u00e9rie et les dimensions de votre arbre de prise de force afin de trouver les composants de protecteur de rechange adapt\u00e9s et garantir ainsi la conformit\u00e9 et la s\u00e9curit\u00e9 de votre exploitation en permanence.<\/p>\n

<\/p>\n
D\u00e9pannage des probl\u00e8mes courants<\/h2>\n
1. Vibrations excessives lors du fonctionnement de la prise de force<\/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. L'embrayage \u00e0 friction patine trop fr\u00e9quemment sous charge normale.<\/strong>
\nSi l'embrayage \u00e0 friction FK96 de l'arbre de prise de force \u00e0 glissement patine de mani\u00e8re r\u00e9p\u00e9t\u00e9e lors de charges de broyage normales que la machine devrait supporter sans probl\u00e8me, il est probable que le ressort d'embrayage soit us\u00e9 ou qu'un disque de friction soit glac\u00e9 suite \u00e0 des surcharges ant\u00e9rieures. V\u00e9rifiez que la bague de r\u00e9glage de l'embrayage est correctement positionn\u00e9e pour un couple de 1\u00a0800\u00a0Nm sur le carter de la s\u00e9rie\u00a02500. Si le r\u00e9glage est correct mais que le patinage persiste, d\u00e9montez l'embrayage et inspectez les disques de friction afin de d\u00e9tecter tout gla\u00e7age, durcissement ou usure excessive. Les disques glac\u00e9s peuvent parfois \u00eatre restaur\u00e9s avec du papier abrasif fin\u00a0; les composants fortement us\u00e9s doivent \u00eatre remplac\u00e9s \u00e0 l'aide de la liste des pi\u00e8ces FK96.<\/p>\n3. Fixation du tube t\u00e9lescopique ou difficult\u00e9 \u00e0 l'\u00e9tendre\/le replier<\/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. Le joug ne se verrouille pas correctement sur l'arbre de prise de force.<\/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. Surchauffe des joints universels ou du carter d'embrayage<\/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![\"Arbre](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-12.webp\")
<\/p>\n
Arbre de prise de force du broyeur et bo\u00eete de vitesses du broyeur<\/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

Q : Cet arbre de prise de force est-il un remplacement direct pour la s\u00e9rie Walterscheid 2500 sur les Fecon BH300 et BH350 ?<\/strong>
\nR : Oui, cet arbre de prise de force est con\u00e7u pour remplacer avec pr\u00e9cision l'arbre de prise de force Walterscheid s\u00e9rie 2500 des mod\u00e8les BH300 et BH350. Toutes les dimensions critiques, notamment le diam\u00e8tre de l'arbre de 1 3\/4\u2033, la sp\u00e9cification de cannelure Z20, la longueur utile \u00e9tendue d'environ 700 mm et l'embrayage FK96 avec un al\u00e9sage de cannelure de 1,750-6 et un couple de glissement de 1\u00a0800 Nm, sont conformes aux sp\u00e9cifications d'origine. Il s'installe directement sur le porte-prise de force du tracteur et l'arbre d'entr\u00e9e du BH300\/BH350, sans adaptateurs, cales ni usinage. Pour toute confirmation dimensionnelle avant commande, veuillez contacter notre \u00e9quipe technique en indiquant votre num\u00e9ro de s\u00e9rie.<\/p>\nQ : Quelle est la longueur exacte de l'arbre de prise de force pour les Fecon BH300 et BH350, et puis-je commander une longueur personnalis\u00e9e ?<\/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>\nQ : Quelle est la diff\u00e9rence entre un arbre de prise de force 540 et un arbre de prise de force 1000, et lequel le BH300\/BH350 n\u00e9cessite-t-il ?<\/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>\nQ : \u00c0 quelle fr\u00e9quence dois-je remplacer les joints universels de l'arbre de prise de force sur la transmission BH300\/BH350 ?<\/strong>
\nA : La dur\u00e9e de vie des joints de cardan d\u00e9pend fortement de la fr\u00e9quence d'entretien, des angles de fonctionnement et de l'intensit\u00e9 de la charge. Dans des conditions id\u00e9ales, avec un graissage r\u00e9gulier (toutes les 8 heures), les croisillons de joint de cardan de l'arbre de prise de force d'une machine de broyage de 200 \u00e0 450 ch devraient durer de 800 \u00e0 1\u00a0500 heures de fonctionnement. Cependant, les op\u00e9rations sur terrain rocailleux, les fortes charges de choc ou tout oubli de graissage r\u00e9duiront consid\u00e9rablement cette dur\u00e9e. V\u00e9rifiez le jeu radial des croisillons toutes les 50 heures. Dans le cadre d'une maintenance pr\u00e9ventive, le remplacement des croisillons de joint de cardan toutes les 600 \u00e0 800 heures est bien moins co\u00fbteux qu'une panne impr\u00e9vue en cours de chantier. CMN Transmission dispose en stock de pi\u00e8ces d\u00e9tach\u00e9es pour le remplacement des croisillons d'arbre de prise de force.<\/p>\nQ : Est-il possible de r\u00e9gler le couple de glissement de l'embrayage FK96, et \u00e0 quel couple glisse-t-il pour les 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>\nQ : CMN Transmission propose-t-elle la fabrication d'arbres de prise de force OEM et sur mesure pour d'autres mod\u00e8les de broyeurs ?<\/strong>
\nR : Oui. CMN Transmission est une entreprise int\u00e9gr\u00e9e de fabrication et de commercialisation, offrant une capacit\u00e9 de production compl\u00e8te d'arbres de prise de force (PDF) sur mesure.

Nous proposons \u00e9galement la fourniture OEM aux fabricants d'\u00e9quipements, avec emballage personnalis\u00e9 et documentation sur mesure. Veuillez communiquer vos exigences techniques \u00e0 notre \u00e9quipe commerciale, notamment les longueurs comprim\u00e9e et d\u00e9ploy\u00e9e, le diam\u00e8tre de l'arbre, le nombre de cannelures, le type d'embrayage et la puissance cible.<\/p>\nQ : Quelle puissance de tracteur et quelles sp\u00e9cifications de prise de force sont n\u00e9cessaires pour faire fonctionner les Fecon BH300 et BH350 ?<\/strong>
\nA : Le Fecon BH300 n\u00e9cessite un tracteur agricole d'une puissance \u00e0 la prise de force (PDF) de 200 \u00e0 450 ch et d'un arbre de prise de force arri\u00e8re de 1\u00a0000 tr\/min avec une cannelure de 1\u00a03\/4\u2033 (Z20). Le BH350 n\u00e9cessite une puissance \u00e0 la PDF de 250 \u00e0 450 ch et une capacit\u00e9 de PDF de 1\u00a0000 \u00e0 1\u00a0325 tr\/min. Le tracteur doit \u00eatre \u00e9quip\u00e9 d'une cabine ferm\u00e9e avec protection de l'op\u00e9rateur, d'une bo\u00eete de vitesses \u00e0 rapport rampant ou d'une transmission hydrostatique, et d'un attelage trois points de cat\u00e9gorie 3 ou 4 avec troisi\u00e8me point hydraulique. De plus, les BH200, BH300 et BH350 n\u00e9cessitent un refroidissement de la bo\u00eete de vitesses lorsqu'ils fonctionnent \u00e0 plus de 300 ch. L'arbre et l'arbre de prise de force de votre tracteur doivent \u00eatre en bon \u00e9tat et ne pr\u00e9senter aucune usure visible des cannelures avant l'installation de cet arbre de transmission de remplacement.<\/p>\nQ : Quelles sont les causes de la d\u00e9faillance pr\u00e9matur\u00e9e de l'arbre de prise de force sur les broyeurs industriels, et comment peut-on l'\u00e9viter ?<\/strong>
\nA : Les causes les plus fr\u00e9quentes de d\u00e9faillance pr\u00e9matur\u00e9e de l'arbre de prise de force (PDF) pour travaux lourds lors du broyage sont : une lubrification insuffisante des roulements \u00e0 aiguilles du joint de cardan et du profil du tube t\u00e9lescopique ; un fonctionnement avec des angles de joint d\u00e9passant constamment 15 degr\u00e9s ; des surcharges r\u00e9p\u00e9t\u00e9es du limiteur de couple qui glacent les disques de friction et r\u00e9duisent l'efficacit\u00e9 de la protection ; et des dommages physiques caus\u00e9s par des d\u00e9bris sur le tube de l'arbre de PDF. Les mesures pr\u00e9ventives comprennent un graissage toutes les 8 heures, le maintien d'une g\u00e9om\u00e9trie correcte entre le tracteur et l'outil, la v\u00e9rification saisonni\u00e8re des r\u00e9glages du limiteur de couple, l'inspection du tube apr\u00e8s tout impact avec une pierre ou une souche, et la surveillance de l'int\u00e9grit\u00e9 du carter de protection de l'arbre de PDF afin d'\u00e9viter tout contact de d\u00e9bris avec l'arbre en rotation.<\/p>\nQ : Cet arbre de prise de force est-il garanti, et quelle est la politique de retour ?<\/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>\nQ : Comment savoir si mon arbre de prise de force doit \u00eatre remplac\u00e9 ou r\u00e9par\u00e9 avec des pi\u00e8ces d\u00e9tach\u00e9es individuelles ?<\/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![\"Arbre](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/05\/PTO-Shaft-for-Fecon-Bull-Hog-Mulcher-7.webp\")

Avis clients<\/h2>\n
Marcus Hollingsworth, directeur de ferme, \u00c9tats-Unis<\/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, entrepreneur en d\u00e9frichement, Australie<\/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, op\u00e9rateur forestier, Canada<\/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, Allemagne<\/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, entrepreneur agricole, France<\/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, entrepreneur agricole, Br\u00e9sil<\/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, \u00e9leveur de b\u00e9tail, Nouvelle-Z\u00e9lande<\/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, gestionnaire des terres de conservation, Afrique du Sud<\/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, entrepreneur forestier, Su\u00e8de<\/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":"Vous recherchez un arbre de prise de force (PDF) de remplacement fiable et compatible avec votre broyeur Fecon Bull Hog BH300 ou BH350\u00a0?
