Paso 9: Prueba de funcionamiento a baja velocidad<\/strong>
\nArranque el motor del tractor y accione la toma de fuerza (TDF) a bajas revoluciones (aproximadamente 1000 rpm para obtener una salida de TDF de unas 540 rpm). Mantenga a todo el personal alejado del eje giratorio durante esta prueba. Observe el eje para detectar vibraciones, ruidos inusuales (clics, golpes o raspaduras), oscilaciones o cualquier se\u00f1al de rotaci\u00f3n de la protecci\u00f3n. Haga funcionar a baja velocidad durante 3 a 5 minutos antes de aumentar gradualmente hasta alcanzar las revoluciones normales de funcionamiento. Si observa alguna anomal\u00eda, detenga el tractor inmediatamente, bloqu\u00e9elo e investigue antes de continuar. Un arranque silencioso y sin vibraciones confirma la correcta instalaci\u00f3n del eje de la TDF agr\u00edcola.<\/p>\n![\"Eje](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-Supreme-Feed-Mixer-7.webp\")

Consejos para el mantenimiento del eje de la toma de fuerza de la mezcladora de alimentos<\/h2>\n
1. Verificaci\u00f3n previa al funcionamiento (antes de cada uso)
\nBefore every mixing session, spend 90 seconds conducting a visual check of the entire PTO shaft for feed mixer assembly. Inspect the guard for cracks, splits, or loose retention chains. Confirm both yoke locking mechanisms (tractor end and mixer end) are in the locked position. Look for any fresh grease or oil leakage at the U-joint seals or slip clutch area, which indicates a bearing seal failure or slip clutch wear. Verify the shear bolt (if fitted) is present, correctly installed, and of the correct grade. Never operate with a missing or substitute shear bolt – an incorrect grade defeats the overload protection system.<\/p>\n
2. Every 50 Operating Hours – U-Joint Greasing
\nCada 50 horas, inyecte grasa multiusos de litio complejo NLGI-2 nueva en cada boquilla de engrase de la junta universal del eje de la toma de fuerza con una pistola de engrase est\u00e1ndar. Contin\u00fae inyectando hasta que aparezca grasa nueva en cada uno de los cuatro sellos de copa de los rodamientos de agujas. Esto confirma que las cuatro posiciones de los rodamientos se han purgado de la grasa vieja contaminada. Inyecte tambi\u00e9n grasa en el punto de engrase del tubo telesc\u00f3pico (accesible a trav\u00e9s de la protecci\u00f3n) para volver a lubricar la zona de solapamiento con perfil de lim\u00f3n. En entornos particularmente h\u00famedos, fangosos o contaminados con ensilaje, reduzca este intervalo a cada 30 horas para maximizar la vida \u00fatil de los rodamientos.<\/p>\n
3. Every 200 Hours – Comprehensive Inspection
\nRemove the PTO shaft guard completely and conduct a full inspection of the exposed shaft components. Check each U-joint for radial play by gripping the shaft close to each joint and attempting to wobble it – any detectable play exceeding 0.5 mm indicates worn needle bearings requiring replacement. Inspect the spline engagement at both ends for fretting wear or rounding of spline teeth. Examine the shaft tube for straightness, dents, or cracks. Inspect the yoke bores for wear or ovalization. Clean all components with a wire brush and compressed air, re-grease, and reinstall the guard. Replace any worn PTO shaft parts before returning to service.<\/p>\n
5. Servicio profundo estacional (anual)
\nAt the end of each main operational season or annually – whichever comes first – perform a deep service on the tractor PTO shafts. Disconnect the shaft completely from both the tractor and mixer, disassemble the telescoping tube halves, and thoroughly clean the profile surfaces with solvent. Inspect the lemon-profile mating surfaces for wear ridges or corrosion pitting that may cause sticking. Pack the profiles generously with fresh grease before reassembly. Inspect the guard’s cone bearings (where fitted) for wear and replace if rough or tight. Check the retention chain hooks for stretch or deformation. This annual service extends PTO shaft life by an estimated 30 to 40 percent compared to reactive maintenance alone.<\/p>\n
6. Almacenamiento y cuidado fuera de temporada
\nDurante los periodos de inactividad, al almacenar la mezcladora de piensos Supreme y su eje de transmisi\u00f3n de la toma de fuerza, aplique una capa de grasa o fluido anticorrosivo a todas las superficies de acero expuestas, especialmente a las estr\u00edas de la horquilla y a las superficies del perfil telesc\u00f3pico. Almacene el eje completamente plegado (sin extender) para minimizar la superficie expuesta del tubo susceptible a la corrosi\u00f3n. Mantenga la protecci\u00f3n colocada durante el almacenamiento para proteger los componentes internos del polvo y los insectos. Si es posible, almacene la mezcladora y el conjunto del eje en interiores o bajo techo para limitar la degradaci\u00f3n por rayos UV del material de protecci\u00f3n de polietileno y la entrada de humedad en los cojinetes.<\/p>\n

<\/p>\n
Fallos comunes y soluci\u00f3n de problemas<\/h2>\n
1. Vibraci\u00f3n excesiva durante el funcionamiento
\nVibration is the most frequently reported problem with agricultural PTO drive shafts on TMR feed mixers and typically has one of four root causes. First, worn or failed universal joint needle bearings: stop the tractor, lockout, grip the shaft close to each U-joint, and attempt to rock it radially. Any play exceeding 0.5 mm confirms worn bearings requiring immediate replacement with a CMN cross journal kit. Second, insufficient tube overlap in the telescoping section, particularly if the shaft was trimmed too short or the tractor-to-mixer distance is at maximum extension: ensure the minimum 150 mm overlap is maintained even during turns. Third, a bent shaft tube from a previous overload event: roll the disconnected tube on a flat surface and check for runout – a straight shaft produces no wobble. Fourth, excessive U-joint angle exceeding 15 degrees: adjust the drawbar height to reduce the angle. Note that vibration at twice the shaft rotation frequency specifically indicates a phasing error between the two yokes – the yoke forks at both ends of the shaft must be aligned in the same plane (phased) for smooth operation. If the shaft was disassembled and incorrectly reassembled out of phase, disassemble and re-phase the yokes before reinstalling.<\/p>\n
2. El eje se desconecta del tractor o de la mezcladora.
\nSpontaneous disconnection of the PTO shaft yoke from the tractor PTO stub or mixer input shaft is a serious safety hazard that must be addressed immediately. The most common cause is a worn quick-disconnect (QD) locking mechanism – the spring inside the push-pin collar weakens with repeated use, and the locking groove on the tractor’s PTO stub or the mixer’s input shaft wears to a radius that no longer reliably retains the pin. Remove the shaft, clean the yoke bore and locking mechanism with solvent, inspect the spring for set (permanent deformation), and replace the QD collar assembly if the spring is weak. Inspect the locking groove depth on the tractor stub – if the groove is worn shallow (less than 1.5 mm deep), the stub shaft must be replaced. Also check that the correct CMN shaft is being used, as a yoke bore diameter mismatch will prevent proper locking. Never attempt to secure a loose yoke with wire or tape as a field expedient – replace the worn components.<\/p>\n
3. Ruido de clic o golpeteo proveniente del eje
\nA rhythmic clicking sound that matches the shaft rotation speed indicates a failing PTO shaft universal joint with dry, contaminated, or broken needle bearings. If the clicking began recently or is intermittent, first attempt to regrease all U-joint nipples with fresh NLGI-2 grease under pressure. If the noise continues after thorough greasing, the bearing needles are physically damaged or the cross journal trunnion surfaces have developed corrosion pitting, and the affected U-joint assembly must be replaced. A deeper, less rhythmic knocking sound that does not correspond directly to shaft speed more likely indicates a loose or fractured PTO shaft shear bolt, a slipping or ratcheting slip clutch, or a loose yoke retaining bolt. Inspect all fasteners after locking out the tractor. A grinding sound at the telescoping tube area indicates insufficient lubrication or corrosion seizure of the profile overlap – apply penetrating oil, work the shaft manually, and re-grease before the next use.<\/p>\n
4. Tubo telesc\u00f3pico atascado o r\u00edgido
\nA telescoping tube that is difficult or impossible to compress by hand – when the shaft is off the tractor – indicates corrosion, dried grease, or packed debris in the lemon-profile overlap area. Remove the guard and expose the tube overlap zone. Apply generous penetrating oil (such as WD-40 or equivalent) to the tube overlap and allow 20 to 30 minutes for the oil to penetrate. Work the shaft back and forth manually using moderate force – avoid hammering or using levers that could dent the tube. Once the tube moves freely, use solvent to clean all residual grease and debris from the profile surfaces, then re-pack with fresh NLGI-2 grease before reassembly. To prevent recurrence, increase the greasing frequency of the telescoping tube from every 50 hours to every 25 hours in wet or silage-contaminated environments. Check the guard for gaps or damage that may be allowing debris ingress into the tube area.<\/p>\n
5. Fallo repetido del perno de corte
\nIf the PTO shaft shear bolt is breaking more than once per season under normal operating loads, the cause is almost certainly an overload condition in the mixer rather than a problem with the shaft itself. Common mixer-side overload causes include: loading the Supreme 300 or 400 beyond its rated capacity, attempting to process excessively long hay (greater than 18-20 cm effective length) that wraps around the auger, introducing metal objects or stones into the mixer box, and operating the mixer at too low an engine RPM causing the auger to stall under load. First, verify that the correct CMN-specified shear bolt grade and diameter is installed – substituting a stronger bolt to “stop it breaking” will transfer the overload failure to the gearbox, causing far more expensive damage. Then investigate and resolve the root cause of the overload. Never install a higher-grade bolt or a steel rod as a substitute for the sacrificial shear bolt.<\/p>\n

Eje de toma de fuerza y \u200b\u200bcaja de engranajes de la mezcladora de piensos<\/h2>\n
The feed mixer PTO shaft – also known as a PTO drive shaft for feed mixer or TMR mixer driveline shaft – is the external power transmission link between the farm tractor and the mixer. It captures the tractor’s PTO output torque (rotating at 540 or 1000 RPM) and delivers it as a continuous, shock-dampened, angularly flexible mechanical drive to the mixer’s gearbox input flange. The PTO shaft’s telescoping design accommodates the changing distance between tractor and mixer during turns, while the universal joints handle misalignment between the two machines. Without the PTO shaft, the tractor’s PTO power cannot reach the mixer at all. The shaft is the first component in the mixer’s power chain – it is also the most exposed to wear, weather, and mechanical stress, making quality and regular maintenance critical to uptime. CMN Transmission’s PTO shaft for Supreme 300, 400, 500, and 600 is engineered to be the strongest link, not the weakest, in this power chain.<\/p>\n
The feed mixer gearbox (also called the TMR mixer gearbox or agitator gearbox) is the internal power converter mounted directly on the mixer’s frame, connecting the PTO shaft input to the vertical auger drive shaft. In Supreme 300-600 series mixers, this is a two-stage heavy-duty planetary gearbox that steps down the tractor’s PTO speed from 540 RPM to the very low auger speed (typically 10-25 RPM) while multiplying torque by a factor of 20 to 50 times. This enormous torque multiplication is what enables the auger to cut, lift, and blend thousands of kilograms of dense feed material per hour. The gearbox operates in an oil bath, is sealed against contamination, and typically requires only periodic oil level checks and annual oil changes. The gearbox is the most expensive single component in the mixer’s drivetrain – often worth several times the PTO shaft cost – which is precisely why the PTO shaft’s overload protection (shear bolt or slip clutch) is designed to sacrifice itself to protect the gearbox from shock damage.<\/p>\n
The PTO shaft and feed mixer gearbox function as an inseparable pair in the Supreme pull-type mixer drivetrain. The PTO shaft’s job is to deliver clean, vibration-free rotational power to the gearbox input at exactly the specified RPM and torque rating. Any vibration, angle error, or torque irregularity in the PTO shaft is transmitted directly into the gearbox’s planetary gear set and output bearings, causing accelerated wear. Conversely, any mechanical problem in the gearbox – a seized output bearing, a broken planet gear, a contaminated oil bath – immediately increases the load on the PTO shaft’s U-joints and overload protection system. The ideal maintenance strategy therefore treats the PTO shaft and gearbox as a matched system: when the PTO shaft shows signs of significant wear at high hours (typically 1,500 to 2,000 operating hours), inspect the gearbox oil for metal particles and bearing noise simultaneously, as both components experience similar fatigue cycles. CMN Transmission supplies both the PTO shaft and compatible feed mixer gearbox assemblies for the Supreme 300-600 series, enabling single-source procurement and guaranteed mechanical compatibility for repair workshops, dealers, and farm operations worldwide.<\/p>\n

Preguntas frecuentes<\/h2>\n
P: \u00bfQu\u00e9 serie de ejes de toma de fuerza (PTO) es compatible con las mezcladoras de alimentaci\u00f3n vertical Supreme 300, 400, 500 y 600?<\/strong>
\nA: The Supreme 300 and 400 pull-type single-auger mixers are best matched with a CAT3 540 PTO shaft featuring a 1-3\/8″ 6-spline tractor end and a 27 x 74.6 mm cross journal. The Supreme 500 is compatible with either CAT3 or CAT4 depending on the gearbox input size fitted to your specific mixer. The Supreme 600 supports both CAT3 (540 RPM standard) and CAT4 configurations (540 or 1000 RPM). CMN Transmission recommends verifying the collapsed length, yoke bore, and spline specification by measuring your existing shaft or consulting your Supreme mixer serial number before ordering.<\/p>\nP: \u00bfPuedo usar un eje de toma de fuerza (PTO) de 1000 RPM en una mezcladora de piensos Supreme 300 o 400?<\/strong>
\nA: The Supreme 300 and 400 pull-type single-auger mixers are designed for 540 RPM PTO operation only – their planetary gearboxes are ratio-matched to 540 RPM input to produce the correct auger speed. Using a 1000 RPM PTO shaft and a 1000 RPM-capable tractor on a 540 RPM-rated gearbox would result in the auger rotating at nearly twice its design speed, causing gearbox overload, rapid bearing failure, and potential structural damage to the mixer. The 1000 PTO shaft option is only applicable to the Supreme 600 when the mixer’s gearbox is specifically configured for 1000 RPM input, or to the T-series (Supreme 500T, 600T, etc.) twin-auger models. Always match the shaft RPM rating to the mixer’s gearbox specification.<\/p>\nP: \u00bfCu\u00e1l es la longitud correcta del eje de la toma de fuerza (PTO) para las mezcladoras de arrastre Supreme?<\/strong>
\nA: The correct PTO shaft length depends on your specific tractor’s PTO stub position and the hitch height of your Supreme mixer, which can vary depending on the drawbar configuration, optional hitch jacks, and any hitch extensions fitted. The standard measurement approach is to hitch the tractor to the mixer on level ground, measure the distance from the tractor’s PTO output stub face to the mixer’s gearbox input face, and select a shaft whose collapsed length places the telescoping tube at the midpoint of its travel at that distance. CMN’s standard lengths for Supreme 300-600 range from approximately 900 mm to 1,400 mm collapsed – custom PTO shaft dimensions outside this range are available.<\/p>\nP: \u00bfCon qu\u00e9 frecuencia debo engrasar las juntas universales del eje de la toma de fuerza de mi mezcladora de piensos?<\/strong>
\nA: CMN Transmission recomienda engrasar todas las juntas universales del eje de la toma de fuerza y \u200b\u200bel perfil del tubo telesc\u00f3pico cada 50 horas de funcionamiento como intervalo est\u00e1ndar. En entornos adversos con exposici\u00f3n significativa a la humedad (operaciones de ganado vacuno en corrales abiertos en climas h\u00famedos, lavados frecuentes en establos lecheros) o contaminaci\u00f3n intensa por ensilaje y piensos h\u00famedos \u00e1cidos, reduzca este intervalo a cada 25 a 30 horas. Utilice grasa de litio compleja multiusos NLGI-2 y bombee hasta que aparezca grasa fresca en el sello del cojinete en cada una de las cuatro copas de aguja por junta universal. Descuidar la lubricaci\u00f3n de las juntas universales es la causa m\u00e1s com\u00fan de falla prematura de las piezas del eje de la toma de fuerza en aplicaciones de mezcladoras de pienso, y el costo de un cartucho de grasa es una peque\u00f1a fracci\u00f3n del costo de un kit de cojinete transversal de repuesto.<\/p>\nQ: Is CMN Transmission’s PTO shaft a direct replacement for Weasler PTO shafts on Supreme mixers?<\/strong>
\nA: Yes. CMN Transmission’s PTO shaft for Supreme feed mixer is engineered as a direct form-fit-function replacement of Weasler PTO shaft assemblies used on Supreme 300, 400, 500, and 600 pull-type mixers. All critical dimensions – collapsed length, extended length, tractor-end spline (1-3\/8″ 6-spline for 540 RPM versions), cross journal size, and yoke bore diameter – are manufactured to match Weasler’s specifications precisely. No adapters, drilling, or modification of the tractor or mixer is required. CMN shafts are also dimensionally compatible with Bondioli and Pavesi, and Walterscheid equivalent series. When ordering as a Weasler replacement, please provide us with the Weasler part number or the shaft’s measured dimensions so we can confirm the exact match before shipment.<\/p>\nP: \u00bfCu\u00e1l es la diferencia entre un eje de toma de fuerza con perno de seguridad y un eje de toma de fuerza con embrague deslizante para mezcladoras de pienso?<\/strong>
\nA: Both protect the mixer’s gearbox and tractor from sudden overload torques, but in fundamentally different ways. A shear bolt PTO shaft uses a precisely graded sacrificial bolt that shears (breaks) at a set torque, instantly disconnecting the drive. After a shear event, the tractor must be stopped, locked out, and a new bolt of the correct grade installed before operation can resume – typically a 5 to 10 minute process. A slip clutch PTO shaft uses spring-loaded friction discs that slip (rotate against each other) at the set overload torque, automatically re-engaging when the overload passes – no manual intervention is needed. For operations running one ration mix per day, the shear bolt is simpler and lower-cost. For high-cycle operations (two or more mixes per day) or where mixed ration compositions create frequent overload events, the slip clutch version offers better workflow continuity.<\/p>\nP: \u00bfPuedo cortar el tubo del eje de la toma de fuerza a una longitud personalizada?<\/strong>
\nA: Yes, the PTO shaft tubing can be field-trimmed if the standard catalog length is slightly too long for your tractor-mixer combination. Use a hacksaw or angle grinder with a metal cutting disc and cut squarely through both the inner and outer tube sections simultaneously. After cutting, deburr all cut edges with a file or deburring tool, and use compressed air or a brush to remove all metal filings from inside both tube profiles before reassembly – metal particles in the tube profile will cause accelerated wear and premature seizure. Verify the minimum tube overlap (150 mm) is maintained at maximum tractor-mixer separation (during turns). Note that trimming should be a last resort – CMN can manufacture custom lengths to order, which provides a cleaner result and retains full warranty coverage on the shaft.<\/p>\nP: \u00bfPara qu\u00e9 sirve el protector del eje de la toma de fuerza y \u200b\u200bes obligatorio por ley?<\/strong>
\nA: El protector del eje de la toma de fuerza (TDF) es una carcasa de polietileno de longitud completa que rodea el conjunto del eje giratorio, evitando el contacto directo entre el personal (o su ropa) y el eje en rotaci\u00f3n. El atrapamiento en el eje de la TDF es una de las principales causas de lesiones graves con maquinaria agr\u00edcola en todo el mundo, ya que el eje puede girar a entre 540 y 1000 RPM y puede enganchar instant\u00e1neamente ropa suelta, guantes o cabello. El protector est\u00e1 anclado tanto al tractor como a la mezcladora mediante cadenas de retenci\u00f3n y debe estar presente y en buen estado durante toda la operaci\u00f3n. Legalmente, operar sin un protector de TDF constituye una infracci\u00f3n del c\u00f3digo de seguridad en los Estados Unidos (OSHA), la Uni\u00f3n Europea (Directiva de Maquinaria), Australia (normativa WHS) y la mayor\u00eda de las dem\u00e1s jurisdicciones. Las reclamaciones de seguros derivadas de accidentes con ejes de TDF sin protecci\u00f3n suelen ser denegadas. CMN incluye un conjunto de protector completo con certificaci\u00f3n CE con cada eje sin coste adicional.<\/p>\nP: \u00bfC\u00f3mo s\u00e9 cu\u00e1ndo necesito reemplazar la junta universal del eje de la toma de fuerza?<\/strong>
\nA: There are four clear indicators that a PTO shaft universal joint has reached end of service life. First, an audible clicking or ticking noise at shaft rotation speed that persists after greasing – this indicates broken or pitted needle bearing surfaces. Second, detectable radial play when you grip the shaft close to each joint and attempt to rock it by hand with the tractor locked out – any play exceeding approximately 0.5 mm confirms worn needle bearings. Third, visible rust or grease leakage from the bearing cup seals, indicating seal failure and bearing contamination. Fourth, increased vibration during operation that was not present when the shaft was newer. Worn U-joints should be replaced promptly – continued operation accelerates wear exponentially and risks complete joint separation, which can be a severe safety hazard. CMN offers individual cross journal replacement kits for all shaft series.<\/p>\nP: \u00bfOfrecen dimensiones personalizadas para el eje de la toma de fuerza o servicios de fabricaci\u00f3n OEM?<\/strong>

Opiniones de los clientes<\/h2>\n
James Harrington, gerente de una granja lechera en Estados Unidos.<\/strong>
\n“We run a Supreme 400 on a 110-cow dairy here in Wisconsin and go through a PTO shaft every couple of seasons depending on how rough the hay is. The Weasler unit we were using before was fine, but the price kept going up. Switched to CMN about 18 months ago – got the CAT3 540 RPM version with the shear bolt. Fit straight onto our New Holland T6 without any fuss, yoke locked first try. We’re now 14 months in, doing two mixing cycles a day, and the shaft is still running smooth. No unusual vibration, no loose U-joints, guard is still intact. Genuinely impressed with the build quality for the price point. Will be reordering the next one from CMN without question.”<\/p>\nPierre Dubois, ganadero, Francia<\/strong>
\n“Order placed for a PTO shaft for our Supreme 500 running at 540 RPM. The shaft arrived in 9 working days from China, which is frankly very fast. Installation was completed in exactly 20 minutes with no adaptations required. We feed approximately 85 dairy cows twice a day, so the equipment is under heavy use. After 8 months of operation, the universal joints show no play and the guard remains in good condition. The quality-to-price ratio is significantly superior to equivalent European brands. I recommend CMN Transmission to my fellow livestock farmers without hesitation. The after-sales service also responded to my questions by email in less than 24 hours.”<\/p>\nThomas Whitfield, productor de ganado vacuno, Australia<\/strong>
\n“Running a Supreme 600 on our beef property outside of Wagga Wagga. We feed 280 Angus steers twice daily through the summer and the PTO shaft takes a hammering – Australian conditions are brutal, lots of dust and heat. The original shaft finally gave up the U-joints after three years of hard work, so I looked around for a replacement. Found CMN Transmission online, sent an enquiry with the shaft dimensions, and got a quote back the same day. Shaft arrived in 11 working days which is excellent for Australia. The slip clutch option they offered me has been a game changer – we had a couple of overload events with old hay that would have sheared the bolt on the old shaft, but this one just slipped and kept going. Very happy.”<\/p>\nKlaus Weber, propietario de una granja, Alemania<\/strong>
\n“We have two Supreme 300s on our farm and sometimes need spare parts quickly, especially during the winter feeding period. The delivery time from CMN was impressive – the PTO drive arrived in 8 working days. The quality is very solid, comparable to Bondioli. I checked the universal joints after 6 months and found no significant play. The price is considerably lower than that of the original supplier. I now keep two spare shafts in stock in case something happens. CMN’s customer service also provided excellent assistance with the technical details – they knew exactly which series fits the Supreme 300. A clear purchase recommendation for other farmers.”<\/p>\nCraig Sutherland, propietario de una granja lechera, Nueva Zelanda<\/strong>
\n“We’ve got a 550-head dairy farm in the Waikato and run the Supreme 500 for our twice-daily TMR feeds. Went through our second PTO shaft in about 4 years – not bad considering we’re doing 700-odd mixing cycles a year. The first replacement we bought locally was overpriced and the U-joints didn’t last 10 months. Found CMN on a farming forum recommendation, ordered the CAT3 1000 RPM version to match our Fendt 718. The fit was perfect, no slop in the yokes, guard is good quality. We’re now at about 18 months and 1,050+ hours on it and I’d put it up against anything else on the market at this price. Service from CMN was responsive – answered all my compatibility questions before I ordered.”<\/p>\nWilliam Thornton, administrador de la finca, Reino Unido<\/strong>
\n“I manage a 3,000-acre mixed livestock estate in Lincolnshire. We use the Supreme 600 to feed a 180-cow pedigree Holstein herd and 400 sheep. The PTO shaft gets serious use – often two or three ration loads per day across the dairy and sheep units. Ordered CMN’s shear bolt version as a direct replacement for a Walterscheid unit that finally gave up after five seasons. I was a bit skeptical of an unfamiliar brand but the product arrived well packaged, with a full spline compatibility chart and multilingual instructions. Installation was straightforward. Six months on and no issues at all. What impressed me most was the guard quality – it’s robust and the retention chain brackets are solid steel, not the stamped thin metal you sometimes get. Good value.”<\/p>\nHendrik van der Berg, productor lechero, Pa\u00edses Bajos<\/strong>
\n“We run our Supreme 400 on a farm with 90 dairy cows in the Achterhoek. We had problems with the shaft from another Chinese supplier – the universal joints were already worn after 4 months. This time we chose CMN following a colleague’s recommendation. The difference is noticeable: sturdier construction, the universal joints still show no play after 10 months, and the plastic protective guard is considerably more robust. Delivery took 10 working days to the Netherlands, which was excellent. What I also appreciate is that CMN provided highly accurate technical specifications – the shaft fitted directly onto our John Deere 6130R. The price is competitive and the quality is consistent. We immediately ordered a spare shaft as well.”<\/p>\nMarc Girardin, criador de ovejas, Francia<\/strong>
\n“We use a Supreme 300 on our sheep farm in Beauce with a flock of 240 ewes. The PTO shaft broke in the middle of winter during an intensive feeding period – very poor timing! I contacted CMN urgently and they were able to ship a replacement shaft express. It arrived in 6 working days. Installation took less than one hour, and the shear bolt supplied with the product was already the correct size for our configuration. What reassured me was that CMN provided detailed technical data sheets and responded to my compatibility questions before the order. The equipment has now been operating for 7 months with no issues whatsoever. I recommend this PTO shaft to sheep farmers.”<\/p>\nCarlos M\u00e9ndez, propietario de un corral de engorde, Argentina<\/strong>
\n“We have a feedlot with 350 steers in Buenos Aires Province and use the Supreme 500 to prepare the ration twice a day. The original cardan shaft broke after three seasons of intensive use. We purchased the CMN Transmission shaft as a replacement – the quote arrived within 24 hours, and shipping took 13 working days to Argentina, which is very reasonable. Installation was straightforward with no modifications needed. We have now used it for 11 months and approximately 800 hours, and the shaft performs excellently. The cross joint has no play, the telescopic section slides smoothly, and the guard remains intact. The price was 35% lower than the equivalent European option. I am very satisfied with both the quality and the service from CMN.”<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"El eje de toma de fuerza (PTO) para las mezcladoras verticales de alimentaci\u00f3n Supreme 300, 400, 500 y 600 de CMN Transmission es un eje de transmisi\u00f3n PTO para tractor dise\u00f1ado espec\u00edficamente para satisfacer las exigencias exactas de potencia y durabilidad de la serie de mezcladoras de arrastre de un solo sinf\u00edn de Supreme.
