Fase 9: Prova a bassa velocit\u00e0<\/strong>
\nAvviare il motore del trattore e innestare la presa di forza a bassi regimi (circa 1.000 giri\/minuto per ottenere una velocit\u00e0 di uscita della presa di forza di circa 540 giri\/minuto). Durante questa prova, tenere tutto il personale lontano dall'albero rotante. Osservare l'albero per rilevare eventuali vibrazioni, rumori insoliti (ticchettii, colpi o raschiature), oscillazioni o qualsiasi segno di rotazione della protezione. Far funzionare il trattore a bassa velocit\u00e0 per 3-5 minuti prima di aumentare gradualmente i giri fino al normale regime di funzionamento. Se si osserva un'anomalia, arrestare immediatamente il trattore, bloccare il sistema e indagare prima di continuare. Un avviamento silenzioso e senza vibrazioni conferma la corretta installazione dell'albero della presa di forza agricola.<\/p>\n![\"Albero](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-Supreme-Feed-Mixer-7.webp\")

Consigli per la manutenzione dell'albero di trasmissione del miscelatore di mangimi<\/h2>\n
1. Controllo pre-operativo (prima di ogni utilizzo)
\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
\nOgni 50 ore, iniettare grasso multiuso al litio complesso NLGI-2 nuovo in ciascun ingrassatore del giunto cardanico dell'albero della presa di forza utilizzando una normale pistola per grasso. Continuare a iniettare fino a quando il grasso fresco non fuoriesce da ciascuna delle quattro guarnizioni a rullini. Ci\u00f2 conferma che tutte e quattro le sedi dei cuscinetti sono state spurgate dal vecchio grasso contaminato. Iniettare grasso anche nel punto di ingrassaggio del tubo telescopico (accessibile attraverso la protezione) per rilubrificare l'area di sovrapposizione del profilo a limone. In ambienti particolarmente umidi, fangosi o contaminati da insilato, ridurre questo intervallo a ogni 30 ore per massimizzare la durata dei cuscinetti.<\/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. Servizio di pulizia profonda stagionale (annuale)
\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. Conservazione e cura fuori stagione
\nQuando si ripone il miscelatore Supreme e il relativo albero cardanico durante i periodi di inattivit\u00e0 produttiva, applicare uno strato di grasso anticorrosivo o un film fluido su tutte le superfici in acciaio esposte, in particolare sulle scanalature del giogo e sulle superfici del profilo telescopico. Riporre l'albero in posizione completamente retratta (non esteso) per ridurre al minimo l'area del tubo esposta e soggetta a corrosione. Mantenere la protezione in posizione durante il rimessaggio per proteggere i componenti interni da polvere e insetti. Se possibile, riporre il miscelatore e l'albero al chiuso o al coperto per limitare la degradazione UV del materiale di protezione in polietilene e l'infiltrazione di umidit\u00e0 nei cuscinetti.<\/p>\n

<\/p>\n
Guasti comuni e risoluzione dei problemi<\/h2>\n
1. Vibrazioni eccessive durante il funzionamento
\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. L'albero si disconnette dal trattore o dalla betoniera
\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. Rumore di clic o colpi provenienti dall'albero
\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 telescopico bloccato o rigido
\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. Rottura ripetuta del bullone di taglio
\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

<\/p>\n
Albero cardanico e riduttore del miscelatore di mangimi<\/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

Domande frequenti<\/h2>\n
D: Quale serie di alberi cardanici \u00e8 compatibile con i miscelatori verticali Supreme 300, 400, 500 e 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>\nD: Posso utilizzare un albero cardanico da 1000 giri\/minuto su un miscelatore di mangimi 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>\nD: Qual \u00e8 la lunghezza corretta dell'albero della presa di forza (PTO) per i miscelatori trainati 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>\nD: Con quale frequenza devo lubrificare i giunti cardanici dell'albero cardanico del mio miscelatore?<\/strong>
\nR: CMN Transmission raccomanda di ingrassare tutti i giunti cardanici dell'albero della presa di forza e il profilo del tubo telescopico ogni 50 ore di funzionamento come intervallo standard. In ambienti difficili con elevata esposizione all'umidit\u00e0 (allevamenti di bovini da carne all'aperto in climi umidi, lavaggi frequenti nelle stalle per bovini da latte) o con forte contaminazione da insilati e mangimi umidi acidi, ridurre questo intervallo a ogni 25-30 ore. Utilizzare il grasso multiuso al litio complesso NLGI-2 e pompare fino a quando il grasso fresco non appare sulla guarnizione del cuscinetto su ciascuna delle quattro coppe ad aghi per giunto cardanico. Trascurare la lubrificazione dei giunti cardanici \u00e8 la causa pi\u00f9 comune di guasti prematuri dei componenti dell'albero della presa di forza nelle applicazioni con miscelatori di mangimi, e il costo di una cartuccia di grasso \u00e8 una minima frazione del costo di un kit di ricambio per il perno trasversale.<\/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>\nD: Qual \u00e8 la differenza tra un albero cardanico con bullone di sicurezza e un albero cardanico con frizione a slittamento per miscelatori di mangimi?<\/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>\nD: Posso tagliare il tubo dell'albero della presa di forza a una lunghezza personalizzata?<\/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>\nD: Qual \u00e8 la funzione della protezione dell'albero della presa di forza ed \u00e8 obbligatoria per legge?<\/strong>
\nA: La protezione dell'albero cardanico (PTO) \u00e8 un involucro in polietilene a tutta lunghezza che circonda l'albero rotante, impedendo il contatto diretto tra il personale (o i loro indumenti) e l'albero in rotazione. L'impigliamento nell'albero cardanico \u00e8 una delle principali cause di gravi infortuni con macchinari agricoli in tutto il mondo, poich\u00e9 l'albero pu\u00f2 ruotare a velocit\u00e0 comprese tra 540 e 1000 giri\/minuto e pu\u00f2 impigliarsi istantaneamente in indumenti, guanti o capelli. La protezione \u00e8 ancorata sia al trattore che al miscelatore tramite catene di sicurezza e deve essere presente e integra durante tutte le operazioni. Per legge, operare senza la protezione dell'albero cardanico costituisce una violazione delle norme di sicurezza negli Stati Uniti (OSHA), nell'Unione Europea (Direttiva Macchine), in Australia (normative WHS) e nella maggior parte delle altre giurisdizioni. Le richieste di risarcimento assicurativo derivanti da incidenti che coinvolgono alberi cardanici non protetti vengono spesso respinte. CMN include un gruppo di protezione completo conforme alla normativa CE con ogni albero senza costi aggiuntivi.<\/p>\nD: Come faccio a sapere quando \u00e8 necessario sostituire il giunto universale dell'albero della presa di forza?<\/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>\nD: Offrite dimensioni personalizzate per gli alberi cardanici o servizi di produzione OEM?<\/strong>
\nR: S\u00ec. CMN Transmission dispone di capacit\u00e0 produttive interne complete, tra cui formatura di tubi CNC, rullatura di scanalature, trattamento termico, test di bilanciamento dinamico e stampaggio di protezioni. Offriamo la produzione di alberi cardanici completamente personalizzati per qualsiasi lunghezza, tipo di scanalatura, configurazione del giunto, profilo del tubo e dispositivo di protezione specificati.

Recensioni dei clienti<\/h2>\n
James Harrington, responsabile dell'allevamento di bestiame da latte, Stati Uniti<\/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, allevatore di bestiame, 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, produttore di bovini da carne, 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, proprietario di un'azienda agricola, Germania<\/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, proprietario di un'azienda lattiero-casearia, Nuova 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, responsabile della tenuta agricola, Regno Unito<\/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, produttore di latte, Paesi Bassi<\/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, allevatore di pecore, 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 Mendez, proprietario di un allevamento intensivo, 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":"L'albero cardanico per i miscelatori verticali Supreme 300, 400, 500 e 600 di CMN Transmission \u00e8 un albero di trasmissione specifico per trattori, progettato per soddisfare le precise esigenze di potenza e durata della serie di miscelatori trainati a coclea singola di Supreme.
