Features of PTO Drive Shaft for Jaylor TMR Mixers

1. Direct OEM-Equivalent Fitment
This PTO driveline shaft is engineered as a direct replacement of Bondioli & Pavesi PTO shaft assemblies originally supplied on Jaylor single auger mixers. The spline profile, yoke dimensions, and tube cross-section match factory specifications precisely, so the shaft slides onto your tractor's 1-3/8" 6-spline PTO stub and locks into the mixer gearbox input without shimming, boring, or adapter hardware.

2. Selectable Overload Protection
Choose between a PTO shaft with slip clutch or a shear bolt PTO shaft configuration based on your operational needs. The slip clutch PTO shaft uses spring-loaded friction discs that disengage automatically when torque exceeds safe limits, ideal for high-frequency mixing. The PTO shaft shear bolt option provides economical overload protection by fracturing a sacrificial bolt at a preset torque threshold, suitable for operations with minimal obstruction risk.

3. Heavy-Duty Universal Joints
Every PTO shaft u joint in this assembly uses precision-ground, case-hardened cross-and-bearing kits rated for the full HP range of Jaylor single auger models (60 to 80 HP at 540 RPM). Greaseable bearing cups with multi-lip seals prevent contaminant ingress, extending service intervals in dusty feedlot and barnyard environments where PTO shaft universal joint failures are most common.

4. Premium Alloy Steel Construction
The PTO shaft tube sections and PTO shaft yoke components are forged and machined from 20CrMnTi alloy steel, then heat-treated for optimal hardness and fatigue resistance. This heavy duty Arbre de prise de force construction withstands the sustained torsional loads produced during TMR mixing of dense silage, whole bales, and wet feed ingredients, even in high-throughput operations running multiple batches daily.

5. Full-Length Safety Guard
The included PTO shaft cover is a two-piece heavy-duty polyethylene guard tube with chain retention anchors at both ends. This non-rotating PTO shaft tubing guard exceeds CE and OSHA safety requirements, maintaining a minimum 25 mm clearance around the spinning driveline at all working angles. Chain anchors connect to fixed points on the tractor drawbar and mixer frame, preventing accidental guard rotation.

6. Full Customization Available
CMN Transmission supports custom PTO shaft configurations to match non-standard tractor setups. Options include alternate PTO shaft sizes, custom collapsed and extended lengths, PTO shaft adapter fittings for 1-3/4" 6-spline or 1-3/8" 21-spline PTO outputs, and wide-angle CV joint upgrades for operations on hilly terrain. Contact our engineering team with your specific measurements for a tailored solution.

How Does Tractor PTO Shaft Power Your Jaylor TMR Mixer

Understanding the working principle of a PTO shaft for single auger TMR mixers helps operators maximize equipment life and feeding efficiency. The entire power transfer chain begins at the tractor's engine, which drives the PTO output stub through the tractor's internal transmission gearing. On all Jaylor 5350, 5400, 5425, and 5575 models, this stub rotates at a governed speed of 540 RPM, matching the 540 PTO shaft spline interface.

When the operator engages the tractor's PTO clutch, rotational energy transfers from the 1-3/8" 6-spline PTO stub into the shaft's tractor-end PTO shaft yoke. A spring-loaded locking collar secures the yoke onto the stub, preventing disengagement during operation. From the yoke, the torque passes through the first PTO shaft universal joint, a precision cross-and-bearing assembly that allows angular flexibility of up to 15 degrees between the tractor and the trailed mixer. This angular compensation is critical because the tractor and mixer are rarely in perfect alignment, especially when navigating feed alleys, turning corners in feedlots, or operating across uneven terrain.

After passing through the first U-joint, rotational force enters the telescoping PTO shaft tube section. The inner and outer tubes slide on a triangular or lemon-profile cross-section, allowing the shaft to extend and compress as the distance between the tractor hitch point and the mixer input shaft changes during turns or terrain undulations. An internal plastic bearing liner prevents metal-to-metal contact between the sliding tubes, reducing friction and eliminating the risk of tube seizure. Proper telescope overlap must be maintained at all times; CMN Transmission marks minimum engagement lines on the inner tube to help operators verify safe overlap during hitching.

At the implement end, the torque passes through a second PTO shaft u joint and into the implement-end yoke, which connects directly to the mixer's planetary gearbox input shaft. Before entering the gearbox, the torque passes through the overload protection device. If a slip clutch PTO shaft is installed, spring-loaded friction plates will slip when the mixing load exceeds the preset torque threshold, protecting the gearbox gears and tractor PTO housing from shock damage. If a shear bolt PTO shaft is installed, a sacrificial Grade 5 bolt fractures cleanly to disconnect the drive.

Inside the Jaylor mixer, the planetary gearbox converts the incoming 540 RPM rotation into a much slower but higher-torque output that drives the patented Square-Cut Auger. This auger processes whole round bales, silage, and supplements into a uniformly blended TMR. The tractor PTO drive shaft must deliver consistent, uninterrupted power throughout the entire mixing cycle (typically 10 to 20 minutes per batch) to achieve proper particle size reduction and homogeneous feed distribution. Any driveline vibration, angular velocity fluctuation, or torque interruption caused by a worn or improperly sized PTO driveline shaft will directly impact mix quality, resulting in feed sorting, inconsistent nutrition delivery, and reduced herd performance.

Applications of Feed Mixer PTO Shafts

1. Dairy Farms
Dairy operations require precise, consistent TMR to maintain milk production and butterfat levels. This PTO shaft for Jaylor feed mixer enables reliable daily mixing of silage, alfalfa hay, grain concentrates, and mineral supplements for herds ranging from 50 to 200 milking cows per batch. The smooth, uninterrupted power transfer ensures particle size uniformity that reduces feed sorting at the bunk, directly supporting higher dry matter intake and improved lactation performance across your milking herd.

2. Beef Cattle Operations
Cow-calf, backgrounding, and finishing operations rely on this agricultural PTO shaft to power Jaylor mixers processing large round bales of grass hay, corn stalks, and distillers grains into balanced growing rations. The heavy-duty construction handles the high torque demand of grinding dense bales, while the telescoping shaft accommodates the varied distances between tractor and mixer in open feedlot layouts. Beef producers running 200 to 500 head consistently choose this shaft for its reliability during peak feeding seasons.

3. Sheep & Goat Enterprises
Small ruminant operations benefit from Jaylor's single auger design, which excels at processing fine-stemmed forages and pelletized supplements into a homogeneous ration that small mouths cannot sort. This tractor PTO shaft provides the consistent 540 RPM power needed for short, frequent mixing cycles typical in sheep and goat feeding programs. The available PTO shaft with slip clutch is particularly valuable here, as string, twine, and net wrap from bales can cause momentary auger jams that the clutch absorbs automatically.

4. Horse & Equine Operations
Equine nutritionists increasingly use TMR strategies to control calorie and fiber intake for performance horses, broodmares, and rescue animals. This PTO drive shaft powers the Jaylor 5350 or 5400 mixer to blend timothy hay, beet pulp, oats, and supplements into controlled rations that eliminate selective eating. The low-profile Jaylor 5400, paired with this reliable driveline, fits easily under barn roof clearances, making it ideal for stabled equine feeding programs that demand precise daily nutrition management.

5. Swine (Pig) Operations
Modern swine operations use TMR mixers to prepare sow gestation rations, nursery blends, and finishing diets that combine corn, soybean meal, mineral premixes, and fibrous co-products like wheat middlings. This PTO shaft for TMR mixers ensures the Jaylor auger achieves the thorough ingredient integration required for uniform nutrient distribution in pelleted or mash-form swine feeds. The shear pin PTO shaft option offers cost-effective protection in swine feeding environments where foreign object contamination is minimal compared to pasture-based cattle operations.

How to Install PTO Shaft on Your Jaylor TMR Mixer

Proper installation of your new tractor PTO shaft is critical for both safety and performance. Before beginning, park the tractor on level ground, engage the parking brake, shut off the engine, and remove the ignition key. Allow any hydraulic systems to depressurize completely. Wear leather work gloves, safety glasses, and steel-toed boots throughout the process. Ensure you have a grease gun loaded with NLGI #2 lithium-complex EP grease, a tape measure, and basic hand tools accessible.

Step 1: Remove the Old Shaft
If replacing an existing PTO driveline shaft, begin by disconnecting the guard tube chains from both the tractor and mixer anchor points. Slide the PTO shaft cover back to expose the implement-end yoke. Release the locking collar on the tractor-end yoke by pulling it back toward the mixer, then slide the shaft off the tractor PTO stub. Lower the implement end carefully, using a support stand if the shaft is heavy (CAT5 assemblies can weigh over 25 kg). Set the old shaft aside for inspection of wear patterns on the U-joints, tube surfaces, and clutch components.

Step 2: Verify Length and Fitment
Before installing your new CMN Transmission PTO shaft for Jaylor feed mixer, measure the distance from your tractor PTO stub face to the mixer gearbox input shaft center at the closest hitch position (fully raised with shortest wheelbase gap). Compare this measurement to the collapsed length of the new shaft. The shaft must not bottom out (inner tube contacting the outer tube stop) at this shortest distance. Next, lower the hitch fully and extend the drawbar to its longest position. The shaft must maintain at least 150 mm (6 inches) of tube overlap at this maximum extension. If the shaft is too long for your setup, CMN Transmission PTO shaft tubing can be cut to length following the cutting guide included with every shipment.

Step 3: Pre-Grease All Fittings
Before connecting the shaft, pump fresh grease into every PTO shaft universal joint fitting until clean grease appears at all four bearing cup seals of each cross assembly. Also apply a thin film of grease to the telescoping tube surfaces and the tractor-end spline bore.

Step 4: Connect the Implement End First
Align the implement-end PTO shaft yoke with the mixer gearbox input spline and slide it into engagement. Secure with the locking mechanism (pin or collar, depending on your model). Verify that the yoke seats fully and rotates freely by hand with no binding.

Step 5: Connect the Tractor End
Pull the spring-loaded locking collar back on the tractor-end yoke, align the spline pattern with the tractor's PTO stub, and push the yoke firmly onto the stub until the collar snaps forward into the locking groove. Tug the shaft outward to confirm the collar has locked. Attach the guard tube chains to the tractor drawbar anchor and the mixer frame anchor to prevent guard rotation.

Step 6: Function Test
With the area clear of personnel, start the tractor, engage the PTO at low idle, and visually confirm smooth rotation with no wobble, vibration, or unusual noise. Increase to operating RPM (540) and monitor for 2 to 3 minutes. Check that the PTO shaft cover guard does not spin with the shaft and that all chain anchors hold securely. Your new feed mixer PTO shaft is now ready for daily operation.

Maintenance Tip for Tractor PTO Drive Shaft

• Lubricate Universal Joints Regularly
  Grease all PTO shaft u joint fittings every 8 operating hours or at the start of each working day during feeding season. Use NLGI #2 lithium-complex EP grease and pump until fresh grease appears at all four bearing cup seals on each cross assembly. In dusty feedlot environments, shorten the interval to every 4 to 6 hours. Neglecting U-joint lubrication is the single most common cause of preventable PTO shaft failure.
• Inspect Telescoping Tube Overlap
  Before each use, visually confirm that the inner PTO shaft tube maintains at least 150 mm (6 inches) of overlap with the outer tube at maximum extension. Insufficient overlap leads to tube separation under load, which can cause catastrophic driveline failure. Also check the tube surfaces for scoring, corrosion, or debris buildup that could restrict free telescoping movement.
• Check Guard Tube and Chain Anchors
  Inspect the PTO shaft cover guard for cracks, warping, or missing retention chains before every operating session. A damaged guard that contacts the spinning shaft will heat rapidly and can melt or shatter, creating a serious entanglement hazard. Replace cracked guard sections immediately. Ensure both anchor chains are attached to their fixed points so the guard cannot rotate with the shaft during operation.
• Inspect Yokes and Locking Collars
  Examine the tractor-end and implement-end PTO shaft yoke components for cracks, elongated spline bores, or worn keyways every 200 operating hours. Test the spring-loaded locking collar for positive snap engagement; a weak or corroded spring can allow the shaft to disengage from the tractor PTO stub during operation. Replace any yoke showing visible spline wear beyond 0.5 mm of clearance.
• Service Overload Protection
  For slip clutch PTO shaft assemblies, check the clutch spring preload annually using a torque wrench and compare to the factory specification stamped on the clutch housing. Springs lose tension over time and allow the clutch to slip prematurely, reducing mixing efficiency. For shear bolt PTO shaft assemblies, always carry spare shear bolts of the correct grade and size. Never substitute a higher-grade bolt, as this defeats the overload protection purpose.
• Seasonal Storage Preparation
  At the end of feeding season, clean the entire PTO drive shaft assembly thoroughly to remove feed residue, mud, and moisture. Apply a rust-preventive coating to all exposed metal surfaces including telescoping tubes, yoke splines, and cross bearing cups. Store the shaft in a dry, covered location away from direct sunlight to prevent guard tube UV degradation. Fully collapse the telescoping section and support the shaft horizontally to avoid bending loads.

Common Troubleshooting for PTO Driveline Shaft Issues

1. Vibrations pendant le fonctionnement
Excessive vibration through the tractor seat and steering wheel while mixing typically indicates a worn PTO shaft universal joint. Shut down, disconnect the shaft, and check each cross assembly for play by gripping opposite bearing cups and attempting to rock them. Any perceptible movement means the cross and bearings need replacement. Also verify that the shaft is not running at excessive operating angles (beyond 15 degrees), which causes cyclic velocity fluctuations even with new U-joints. Adjust the tractor drawbar height to minimize the angle between tractor PTO stub and mixer input shaft.

2. Slip Clutch Engaging Prematurely
If the slip clutch PTO shaft slips during normal mixing loads that previously did not cause slipping, the clutch springs have likely lost preload tension. This is common after 500+ operating hours or extended storage under compression. Remove the clutch assembly and measure spring free length against the factory specification. Replace springs that have lost more than 10% of their original free length. Also inspect the friction disc surfaces for glazing or contamination with oil or grease, which reduces friction coefficient and causes premature slip.

3. Shaft Will Not Telescope Freely
If the inner and outer PTO shaft tube sections bind or resist sliding, the cause is typically corrosion buildup, dried feed residue packed between the tube profiles, or a damaged internal plastic bearing liner. Disassemble the tubes, clean both surfaces with a wire brush and solvent, inspect the liner for scoring or debris, and apply a thin coat of anti-seize compound before reassembly. Never force a stuck telescoping joint with a hammer, as this can deform the tube profile and create permanent binding.

4. Shaft Disconnects from Tractor PTO
If the tractor PTO drive shaft disengages from the PTO stub during operation, the locking collar spring is either broken or the collar is not engaging the retention groove on the PTO stub. Inspect the collar spring, replace if fractured or weak, and verify that the PTO stub groove is clean and not worn below specification. Also check that the correct PTO shaft yoke size matches your tractor's PTO stub diameter and spline count.

5. Shear Bolt Breaks Repeatedly
Frequent PTO shaft shear bolt failure during normal mixing indicates either an incorrect bolt grade (too soft for the application), a mechanical obstruction inside the mixer (foreign object jammed in the auger), or excessive PTO engagement speed. Always engage PTO at low idle (under 300 RPM) and ramp to operating speed gradually. Inspect the mixer auger and tub for trapped rocks, wire, or frozen feed before each batch. Use only the bolt grade and size specified for your shaft model; never substitute a higher-strength bolt, as this transfers shock loads to the gearbox instead of the sacrificial bolt.

Feed Mixer PTO Shaft and Feed Mixer Gearbox

The feed mixer PTO shaft and the feed mixer gearbox are two interdependent components that together form the complete power transmission system of any TMR mixer, including all Jaylor single auger models. Understanding their relationship is essential for maintaining reliable mixing performance and preventing costly driveline failures.

The PTO drive shaft serves as the external power link, transferring rotational energy from the tractor's engine through the PTO output stub to the mixer's input connection point. It is engineered with telescoping tube sections, PTO shaft universal joint assemblies, and an overload protection device (slip clutch or shear bolt) to deliver smooth, flexible, and protected power transfer across varying distances and angles between the tractor and the trailed mixer. The shaft operates at the tractor's governed PTO speed, typically 540 RPM for Jaylor single auger mixers.

The feed mixer gearbox, mounted internally on the mixer frame directly below the vertical auger, receives this 540 RPM input from the tractor PTO shaft and converts it through a planetary gear reduction system into the much slower but significantly higher-torque output required to rotate the heavy mixing auger. A typical Jaylor planetary gearbox reduces the 540 RPM input to approximately 20 to 30 RPM auger speed while multiplying torque by a ratio of roughly 18:1 to 27:1. This massive torque multiplication is what enables the auger to cut through and blend dense round bales, wet silage, and heavy grain components.

The connection point between the PTO driveline shaft and the gearbox input is where the overload clutch sits. This position is intentional: the clutch protects the gearbox gears, bearings, and seals from shock loads before they enter the gearbox housing. If an undersized or improperly configured PTO shaft is used, torque spikes can pass directly into the gearbox, causing gear tooth damage, bearing failure, or oil seal leaks. CMN Transmission manufactures both agricultural PTO shafts and feed mixer planetary gearboxes, giving customers the advantage of a matched driveline system where the shaft clutch rating, spline profile, and rotational speed are precisely calibrated to the gearbox input requirements. When ordering a replacement PTO shaft for TMR mixers, we recommend inspecting the gearbox input bearing, oil level, and gear condition at the same time.

FAQ

Q: What PTO shaft size do I need for a Jaylor 5350, 5400, 5425, or 5575 single auger TMR mixer?
A: All Jaylor single auger models (5350, 5400, 5425, 5575) operate on a 540 PTO shaft at 540 RPM. The typical shaft series is CAT4 or CAT5, depending on the specific model and HP requirement. The tractor-end spline is 1-3/8" 6-spline for 540 RPM operation. CMN Transmission can confirm the exact PTO shaft sizes for your specific mixer serial number upon request.

Q: Can this PTO shaft replace the original Bondioli & Pavesi driveline on my Jaylor mixer?
A: Yes. This shaft is specifically engineered as a direct replacement of Bondioli & Pavesi PTO shaft assemblies originally fitted on Jaylor single auger mixers. All spline profiles, yoke dimensions, universal joint sizes, and tube cross-sections match OEM specifications, ensuring a drop-in fit without modifications, adapters, or special tools.

Q: Should I choose a slip clutch PTO shaft or a shear bolt PTO shaft for my feed mixer?
A: A slip clutch PTO shaft is recommended for operations that frequently encounter bale twine, net wrap, or foreign objects that may jam the auger, as it slips and re-engages automatically without downtime. A shear bolt PTO shaft is more economical and suitable for controlled environments where auger jams are rare. Contact CMN Transmission to discuss which overload protection best fits your operational profile.

Q: How often should I grease the universal joints on my agricultural PTO shaft?
A: Grease all PTO shaft u joint fittings every 8 operating hours or at the start of each working day. Use NLGI #2 lithium-complex EP grease and pump until clean grease appears at all four bearing cup seals on each cross assembly. In dusty or wet conditions, reduce the interval to every 4 to 6 hours. Consistent lubrication is the single most effective way to extend the service life of your PTO shaft universal joint assemblies.

Q: Can I use a 1000 RPM PTO shaft on a Jaylor single auger TMR mixer?
A: No. All Jaylor 5350, 5400, 5425, and 5575 models are designed exclusively for 540 RPM operation. Connecting a 1000 RPM PTO shaft or running the mixer from a 1000 RPM PTO output will severely overspeed the planetary gearbox and auger, creating dangerous operating conditions and voiding the gearbox warranty. If your tractor has a 1000 RPM-only PTO, a speed-reducing PTO shaft adapter is required.

Q: Does CMN Transmission offer custom PTO shaft lengths for non-standard tractor setups?
A: Yes. CMN Transmission supports full custom PTO shaft manufacturing, including non-standard collapsed and extended lengths, alternate spline configurations, and special yoke designs. Provide your tractor model, hitch-to-PTO-stub measurement, and drawbar extension range, and our engineering team will specify the correct PTO shaft tubing dimensions for your setup. Custom orders are typically delivered within 15 to 20 business days.

Q: What is included with the PTO shaft when I order from CMN Transmission?
A: Each PTO drive shaft ships as a complete assembly including: tractor-end yoke with locking collar, implement-end yoke, two PTO shaft universal joint cross-and-bearing kits (pre-installed), telescoping inner and outer shaft tubes, overload protection device (slip clutch or shear bolt as selected), full-length polyethylene PTO shaft cover guard with chain retention, and spare shear bolts (if shear bolt option selected). All components are pre-assembled and ready for installation.

Q: How do I know when to replace my PTO shaft parts instead of the whole shaft?
A: Individual PTO shaft parts such as cross-and-bearing kits, yokes, and shear bolts can be replaced when wear is limited to a single component. However, if the PTO shaft tube shows visible scoring, the yoke spline bore is elongated beyond 0.5 mm clearance, or multiple U-joints have failed within a short period, a complete shaft replacement is more economical and safer than piecemeal repairs. CMN Transmission offers both complete assemblies and individual replacement parts.

Q: What safety certifications does this heavy duty PTO shaft carry?
A: All CMN Transmission PTO drive shafts are manufactured under ISO 9001 quality management systems, carry CE certification for European market compliance, and hold TS16949 automotive-grade quality certification. The safety guard meets both CE directive and OSHA requirements for rotating driveline shielding. These certifications ensure that every heavy duty PTO shaft leaving our facility meets international safety and performance standards.

Q: Can this PTO shaft also fit other brands of single auger feed mixers?
A: While this shaft is specifically designed for Jaylor 5350, 5400, 5425, and 5575 models, the standard 540 PTO shaft spline configuration (1-3/8" 6-spline tractor end) is common across many single auger TMR mixer brands. If your mixer uses the same gearbox input spline size and shaft series, this driveline may be compatible. Contact CMN Transmission with your mixer brand, model, and gearbox input specifications, and our team will confirm fitment or recommend the correct PTO shaft for single auger TMR mixers for your machine.

Avis clients

James Hoffmann, Dairy Farm Owner, United States
"We run a 300-head dairy in central Wisconsin and our Jaylor 5425 is the backbone of our feeding program. The original Bondioli shaft gave us about five seasons before the U-joints started making noise. Ordered the CMN Transmission CAT4 replacement with the slip clutch option, and the fit was perfect, same spline, same length, slid right onto our JD 6120M PTO stub with no fuss. We're about 220 hours into this shaft now, mixing corn silage and haylage twice a day, and it runs just as smooth as day one. The guard tube feels thicker than the original too. Honestly, at roughly half the price of the Bondioli dealer quote, I can't see any reason to go back."

Tyler MacKinnon, Feedlot Manager, Canada
"Purchased two PTO shafts from CMN for our twin Jaylor 5575 mixers at our 1,200-head feedlot in southern Alberta. Shipping to Canada was surprisingly quick, about 12 business days door to door. The shafts came well packaged in wooden crates, no transit damage at all. Installation took maybe 20 minutes each since the spline profiles matched our Massey Ferguson 7720s exactly. We've been running them since last October through a full Canadian winter with no issues. The grease fittings are positioned where you can actually reach them, which is a big improvement over the old Walterscheid units. Good value for a commercial operation buying multiples."

Grant Patel, Sheep Farmer, New Zealand
"Running a 600-ewe sheep enterprise in the Waikato region. Our Jaylor 5350 with the CMN PTO shaft has been solid for about 18 months now. The slip clutch saved us twice when bale twine wrapped around the auger, just slipped for a second, cleared itself, and kept going. Only reason I'm giving four stars instead of five is that the instructions were a bit brief on adjusting the clutch tension, had to email their team for clarification. They responded within a day with a detailed guide, so the customer service is definitely there. Would recommend to other livestock operations in New Zealand."

Klaus Braun, Mixed Farm Operator, Germany
"Our operation in Bavaria runs a Jaylor 5400 low-profile mixer inside a barn with only 2.4 meters of clearance, so the PTO shaft geometry has to be right or it won't work. The CMN shaft with the 1-3/8 inch 6-spline tractor end connected to our Fendt 313 without problems. Collapsed length was correct, we had enough overlap even at the tightest turn radius. Build quality of the yokes and the cross bearing assemblies is comparable to what we see from European brands, but the price was significantly more reasonable. After 350 hours of operation with no play in the joints, I have no complaints. Very professional supplier."

Daniel Crawford, Cattle Rancher, Australia
"I manage a 200-head Angus cow-calf operation in New South Wales. We bought the CMN PTO shaft as a direct replacement for our worn-out driveline on the Jaylor 5425. I was a bit nervous ordering from overseas, but CMN's sales rep walked me through the specifications on WhatsApp to make sure we got the right one. Arrived in about two weeks via sea freight to Sydney, then trucked to our property. The shaft has been running since March, about 160 hours, mixing Rhodes grass hay and cotton seed meal. No vibration, no heat buildup at the U-joints. Really pleased with the product and the support."

Pieter van der Merwe, Agricultural Contractor, South Africa
"We operate a TMR contract mixing service in the Free State province, servicing about 15 different dairy and beef farms with our fleet of Jaylor mixers. We've now installed CMN PTO shafts on three of our machines (two 5425s and one 5575) and they've all performed consistently. What I appreciate most is the factory-direct pricing, when you're buying for a fleet, the cost savings add up fast. The shear bolt option works well for our situation since our operators know the drill when a bolt goes. CMN also sent us extra shear bolts and a full set of replacement U-joint kits with each order, no extra charge. That kind of attention keeps a customer loyal."

Ricardo Mendes, Dairy Cooperative Manager, Brazil
"Our dairy cooperative near Sao Paulo purchased the CMN PTO driveline shaft for a Jaylor 5350 that we use to mix sugarcane bagasse, soybean hulls, and mineral supplements. The tropical humidity here is brutal on metal components, but after 10 months and roughly 400 operating hours, the shaft shows no corrosion on the tube surfaces or the yoke splines. The cross bearings are still tight with no play. We grease every morning before mixing, following CMN's recommendation, and the shaft has been trouble-free. Delivery to Brazil took about 18 days, which was faster than expected for international shipping. Excellent product for the investment."

Antoine Mercier, Goat Farm Owner, France
"We recently equipped our 180-goat cheese operation in Normandy with a Jaylor 5350 and ordered the CMN replacement PTO shaft at the same time as the mixer. The shaft quality is very good, heavy and solid feeling, nice machining on the yokes and splines. The slip clutch engages smoothly and has protected the gearbox at least three times already when hay strings got caught around the auger. My only slight concern was that the packaging labels were in English and Korean, with no French documentation, but the engineering drawings were clear enough that installation was straightforward. I would buy again and would be happy to see a French-language instruction sheet in the future."

Carlos Herrera, Feedlot Operations Director, Mexico
"Our feedlot in Jalisco state processes about 2,000 head of cattle and we run two Jaylor 5575 mixers, morning and afternoon shifts. We've tried three different PTO shaft brands over the years, and the CMN shafts have given us the best combination of price and durability so far. The CAT5 universal joints handle the 80 HP load from our New Holland T6 tractors without any heating or noise issues after over 500 hours. Delivery to Mexico was straightforward, about 15 days, and the CMN team helped us with the customs paperwork. For commercial feeding operations looking for a reliable, affordable tractor PTO shaft, CMN is a solid choice."
