Key Features of PTO Shaft for Bush Hog Flexwing Mower

1. Constant Velocity Joint Design
This agricultural PTO shaft features a constant velocity (CV) joint that maintains a uniform rotational speed regardless of the operating angle between the tractor and mower. Unlike standard Hooke-type PTO shaft universal joint configurations, the CV design eliminates cyclic speed fluctuations, reducing vibration and extending the service life of connected gearboxes and bearings in your flexwing mower system.

2. Integrated Two-Disc Slip Clutch Protection
Each wing shaft includes a CAT4 two-disc slip clutch PTO shaft rated at 1200 Nm of torque. When the mower blade strikes a hidden obstacle such as a rock, stump, or fence post, the clutch disengages momentarily to absorb the shock. This prevents catastrophic damage to the PTO driveline shaft, gearbox internals, and tractor transmission, saving thousands of dollars in potential repair costs.

3. Multi-Spline Tractor Compatibility
Available in three tractor-side spline configurations (1.375"-6, 1.375"-21, and 1.750"-20), this tractor पीटीओ ड्राइव शाफ्ट fits a wide range of agricultural tractors commonly paired with Bush Hog flexwing mowers. Whether you run a compact utility tractor or a high-horsepower row crop model, a matching PTO shaft yoke configuration is available without needing aftermarket adapters.

4. CAT4 and CAT5 Power Ratings
The shaft system is offered in both Category 4 (rated at 60 HP @ 540 PTO shaft RPM) and Category 5 (rated at 90 HP @ 540 RPM) series. This allows operators to match the driveline capacity precisely to their tractor's power output. Proper sizing of the PTO shaft sizes category ensures maximum efficiency while preventing premature wear from under-specifying the driveline.

5. Complete Driveline Assembly
Unlike competitors that sell individual components, CMN Transmission supplies the full driveline package: main shaft, center shaft, and wing shafts with clutches. Every PTO shaft tube, cross bearing, and guard is included so operators receive a complete, ready-to-install system. This eliminates the hassle of sourcing PTO shaft parts separately and ensures all components are properly matched in terms of torque capacity and dimensional tolerances.

6. Heavy Duty Guard Tubes and Safety Shields
All rotating sections are enclosed within robust PTO shaft cover guard tubes that meet safety standards for agricultural equipment. The guard tubes rotate freely on bearing supports, preventing entanglement hazards during operation. The heavy duty PTO shaft guard construction resists impact damage from field debris and maintains its structural integrity even in rough terrain conditions typical of flexwing mowing applications.

How the Flexwing Mower PTO Shaft Works

A PTO shaft for Bush Hog flexwing mowers operates as the critical mechanical link that transfers rotational energy from the tractor's power take-off output to the mower's cutting system. Understanding this process helps operators maintain the driveline properly and maximize equipment longevity.

• Power Initiation at the Tractor
  The process begins when the operator engages the tractor's PTO clutch. The tractor engine transmits power through the transmission to the rear PTO stub shaft, which rotates at a standardized 540 PTO shaft speed (540 revolutions per minute). The main tractor PTO shaft connects to this stub via a splined PTO shaft yoke that slides onto the tractor's output spline. The spline connection ensures positive rotational engagement while allowing the shaft to telescope in and out as the distance between tractor and mower changes during turns or terrain variations.
• Power Transfer Through the Main Shaft
  The main PTO drive shaft carries rotational force from the tractor to the mower's central power divider gearbox. The constant velocity joint at the mower end compensates for angular misalignment between the tractor drawbar and the mower hitch point. Inside the CV joint, precision-machined balls ride in grooves that maintain equal input and output speeds across the full operating angle range. The telescoping PTO shaft tubing uses profile tube sections (typically triangular or lemon-shaped cross-sections) that slide within each other to accommodate changes in working length.
• Power Distribution to the Wings
  At the power divider gearbox, the single input is split into three output paths: one center shaft and two wing shafts. The center shaft (CAT4 with 1.375-6 spline) drives the center cutting deck directly beneath the main frame. The two wing PTO drive shafts extend outward to drive the left and right wing gearboxes. Each wing shaft passes through its own telescoping section and PTO shaft u joint to accommodate the folding and unfolding motion of the wings.
• Overload Protection Mechanism
  The two-disc slip clutch integrated into each wing shaft provides automatic overload protection. Under normal operation, spring pressure keeps the friction discs locked together, transmitting full torque (up to 1200 Nm). When an obstruction causes a sudden spike in torque beyond the clutch's set point, the discs slip against each other rather than allowing the shock load to travel back through the PTO driveline shaft. After the obstruction passes, the clutch re-engages automatically and the cutting deck returns to full speed within seconds. This self-resetting feature means no PTO shaft shear bolt replacement is needed, unlike simpler shear-pin protection systems, significantly reducing downtime during mowing operations.

Applications of PTO Drive Shaft for Flexwing Mower

1. फसल अवशेष प्रबंधन
After harvesting corn, soybeans, cotton, or sorghum, the leftover stalks and stubble must be shredded to promote decomposition and prepare fields for the next planting cycle. A Bush Hog flexwing mower powered by this agricultural PTO shaft efficiently processes crop residue across wide swaths (up to 15 feet), turning tough stalks into fine mulch that integrates into the topsoil. Proper residue management reduces pest harboring and improves nutrient recycling.

2. चारागाह प्रबंधन
Cattle and livestock operations require regular pasture mowing to control weeds, remove unpalatable growth, and encourage fresh grass regrowth. The PTO shaft for flexwing mower delivers reliable power to cover hundreds of acres of pastureland efficiently. Its slip clutch mechanism protects the entire driveline when hidden rocks or old fence posts are encountered in rough pasture terrain, which is a frequent challenge on large grazing properties.

3. बाग और अंगूर के बाग का प्रबंधन
Fruit orchards and vineyards need regular mowing between rows to control competing vegetation and reduce pest habitat. The Bush Hog flexwing mower, connected through this precise PTO driveline shaft, handles the between-row mowing with the center deck while the folded wings can clear adjacent rows. Orchard operators benefit from the shaft's smooth power delivery, which prevents the jerky operation that can damage low-hanging branches or trellis systems.

4. Grass Maintenance
Commercial turf facilities, sports complexes, airports, and large institutional grounds require regular grass maintenance over expansive areas. The wide cutting width of flexwing mowers, driven by this heavy duty PTO shaft, allows groundskeeping crews to cover maximum acreage per hour. The constant velocity joint design ensures smooth power delivery even at varying mowing angles and ground contours.

5. सड़क किनारे की वनस्पति का नियंत्रण
Government highway departments, county road crews, and private contractors use flexwing mowers for roadside and right-of-way vegetation management. This tractor PTO shaft assembly withstands the demanding duty cycles of municipal mowing operations where operators mow for 8 to 10 hours daily, often encountering mixed vegetation including saplings, brush, and dense weeds. The wide cut width reduces the number of passes needed along highway corridors.

6. पंक्तिबद्ध फसलों के डंठलों को काटना
After mechanical harvest, row crops like corn and cotton leave behind heavy stalks that interfere with subsequent tillage and planting operations. A flexwing mower equipped with this 540 PTO shaft assembly processes these tough stalks at high speeds, breaking them down to manageable sizes. The CAT5 option, rated at 90 HP, is particularly suited for shredding dense corn stalks that demand maximum driveline power throughput.

Flexwing Mower PTO Shaft Installation Steps

Proper installation of your new PTO shaft for Bush Hog flexwing mowers is critical for safe operation and maximum service life. Follow these steps carefully. Always ensure the tractor engine is off, the PTO is disengaged, and the ignition key is removed before beginning any installation work.

Step 1: Pre-Installation Inspection
Before removing your old PTO drive shaft, inspect the new shaft assembly to verify it matches your specific Bush Hog model (2212, 2215, 2815, 2810, 1815, or 1812). Confirm the tractor-side spline type matches your tractor's PTO output (1.375"-6, 1.375"-21, or 1.750"-20). Check that the PTO shaft yoke, cross bearings, guard tubes, and clutch assemblies are all present and free from shipping damage. Lay the shaft assembly out on a clean surface and extend the telescoping sections to verify smooth sliding action.

Step 2: Remove the Old Shaft Assembly
Support the old shaft with a floor jack or stand to prevent it from falling during disconnection. Release the locking collar or retaining pin on the tractor-side yoke and slide it off the PTO stub shaft. At the mower end, disconnect the shaft from the power divider input by removing any retaining hardware. For wing shafts, disconnect from both the power divider output and the wing gearbox input. Label each shaft position (left wing, center, right wing) to ensure correct orientation during reinstallation.

चरण 3: मुख्य शाफ्ट स्थापित करें
Apply a thin layer of lithium-based grease to the tractor PTO stub shaft splines. Align the tractor PTO drive shaft yoke splines with the PTO stub and slide the yoke onto the shaft until the locking mechanism engages. Verify the lock pin or collar is fully seated. At the mower end, connect the constant velocity joint to the power divider input shaft, ensuring the splines mesh completely. Secure with the original retaining hardware and torque to manufacturer specifications.

Step 4: Install the Center and Wing Shafts
Install the center shaft first, connecting from the power divider center output to the center gearbox input. Ensure the 1.375-6 spline connections are fully engaged on both ends. Next, install the wing shafts by connecting each one from the power divider side output (1.750-20 spline) to the respective wing gearbox input (1.375-6 spline with two-disc clutch). Verify each PTO shaft universal joint moves freely through its full range of motion without binding.

Step 5: Adjust and Test
With all shafts connected, manually rotate the driveline by hand to check for smooth operation. Fold and unfold the mower wings to verify the wing shafts have adequate telescoping travel and that no PTO shaft cover guard makes contact with the frame. Attach all safety guard chains. Start the tractor, engage the PTO at low idle, and listen for any unusual noise or vibration. Gradually increase RPM to the operating speed of 540 RPM. Observe the driveline for at least two minutes before beginning mowing operations. After the first hour of operation, shut down and re-check all connections and retaining hardware.

How to Choose the Right Tractor PTO Shaft for Flexwing Mower

• Identify Your Mower Model
  Start by confirming the exact Bush Hog model number (2212, 2215, 2815, 2810, 1815, or 1812) from the serial plate on the mower frame. Different models may have varying shaft lengths and gearbox input sizes. The model number determines which center shaft configuration and wing shaft lengths are required for a correct-fit replacement of Bush Hog PTO shaft assembly.
• Check Your Tractor PTO Spline Type
  Measure the tractor's PTO stub shaft spline configuration carefully. The three common options are 1.375"-6 (six spline), 1.375"-21 (twenty-one spline), and 1.750"-20 (twenty spline for higher HP tractors). An incorrect spline match will prevent the PTO shaft yoke from engaging, or worse, cause dangerous slippage under load. Your tractor's operator manual lists the exact PTO spline specification.
• Match the Category to Your Tractor HP
  Select CAT4 (S6 series) if your tractor produces up to 60 HP at the PTO, or CAT5 (S8 series) for tractors producing up to 90 HP at the PTO. Under-sizing the PTO shaft sizes category for your tractor's output will lead to premature driveline failure. Over-sizing slightly is acceptable and provides an additional safety margin, but adds unnecessary weight and cost.
• Determine PTO Speed Requirements
  Bush Hog flexwing mowers in the 1812 through 2815 range are designed for standard 540 PTO shaft operation. If your tractor has a dual-speed PTO (540/1000 RPM), ensure it is set to 540 RPM mode before connecting the shaft. Operating a 540 RPM-rated mower at 1000 PTO shaft speed will cause dangerous over-speeding of the cutting blades and immediate driveline damage.
• Evaluate Clutch Type and Torque Rating
  The standard two-disc slip clutch rated at 1200 Nm provides effective overload protection for most mowing conditions. If you frequently operate in extremely rocky fields or clear heavy brush where impacts are common, you may want to discuss upgraded clutch options with CMN Transmission. For lighter-duty applications, a shear pin PTO shaft or shear bolt PTO shaft alternative can also be configured on request.
• Consider Custom Shaft Lengths
  If your tractor-to-mower distance differs from standard configurations due to a non-standard drawbar or hitch setup, CMN Transmission offers custom PTO shaft lengths. Provide the closed length (minimum distance between tractor PTO stub and mower input) and open length (maximum distance at full turn). The PTO shaft tubing telescoping range will be manufactured to match your specific operational requirements.

Common Troubleshooting for PTO Driveline Shafts

1. संचालन के दौरान अत्यधिक कंपन
If you notice unusual vibration after installing or operating your PTO drive shaft, begin by checking the PTO shaft u joint cross bearings. Worn or dry universal joints are the most common cause of driveline vibration. Grab the shaft near each joint and attempt to rock it; any perceptible play indicates the cross bearing needs replacement. Also verify that the telescoping sections are properly aligned and that the profile tubes have not become damaged or bent. Misalignment between the tractor PTO and mower input shaft of more than 15 degrees can also generate vibration; adjust the mower hitch height to bring the driveline closer to horizontal.

2. Slip Clutch Engaging Too Frequently
If the PTO shaft with slip clutch slips during normal mowing without encountering obstructions, the clutch friction discs may be worn or the spring pressure may have weakened. Remove the clutch housing and inspect the friction disc surfaces for glazing, wear, or contamination from oil or grease. Measure the disc thickness against the minimum specification. If the discs are within tolerance, check the compression springs for correct free length. Additionally, verify that you are not overloading the mower by cutting vegetation that exceeds the mower's rated capacity or by running too fast in heavy material.

3. शाफ्ट सुचारू रूप से टेलीस्कोप नहीं करेगा
Difficulty extending or retracting the telescoping PTO shaft tube sections is often caused by corrosion buildup, dried grease, or damage to the profile tube surfaces. Disconnect the shaft from both the tractor and mower, clean the profile tube sections thoroughly with a solvent, inspect for scoring or dents, and apply fresh lithium-based grease before reassembling. If the shaft binds at the same point each time, the tube may be bent and should be replaced. Never operate a driveline that does not telescope freely, as this will transmit thrust loads to the tractor PTO bearings and mower gearbox seals.

4. Unusual Noise from the Driveline
Clicking, clunking, or grinding noises typically indicate worn PTO shaft universal joint bearings, damaged CV joint internals, or loose yoke connections. Stop the mower immediately if you hear metallic grinding, as continued operation can cause the shaft to separate under load, creating a serious safety hazard. Inspect all joints, yoke retaining hardware, and spline connections. A rhythmic clicking that speeds up with PTO RPM usually points to a failing cross bearing. Replace worn components promptly and always use genuine PTO shaft parts rated for your shaft's category to maintain safe operation.

5. Guard Tube Making Contact with Frame
If the PTO shaft cover guard tube contacts the mower frame during wing folding or operation, check that the guard is rotating freely on its support bearings. Seized guard bearings will cause the entire guard assembly to rotate with the shaft and strike nearby structures. Also verify the shaft length is correct for your model; an overly long shaft will compress at minimum working distance, forcing the guard tube into the frame. Adjust the tractor drawbar position if needed to achieve proper driveline geometry. Ensure all guard chain anchors are connected to allow the guard tube to float independently of the shaft rotation.

The flexwing mower PTO shaft and the rotary cutter gearbox are two interdependent components that form the heart of any flexwing mowing system. Understanding their relationship is essential for proper equipment selection, maintenance scheduling, and optimal mowing performance. Together, these components convert horizontal rotational energy from the tractor into high-speed vertical blade rotation at each cutting deck.

The PTO Shaft: Power Delivery System
The PTO driveline shaft serves as the power delivery conduit. It transfers the tractor's rotational energy across the distance between the tractor PTO output and the mower's gearbox inputs. In a flexwing configuration, the main shaft feeds the central power divider, which then distributes power through center and wing shafts to each individual cutting deck. The shaft must accommodate angular misalignment (handled by universal joints or CV joints) and distance variation (handled by telescoping tubes) while maintaining consistent power delivery at the rated RPM.

The Rotary Cutter Gearbox: Power Conversion Unit
The rotary cutter gearbox sits atop each cutting deck and performs the critical function of converting the horizontal shaft rotation into vertical spindle rotation that drives the cutting blades. These gearboxes typically use spiral bevel gears to make the 90-degree directional change while simultaneously adjusting the speed ratio. In a Bush Hog flexwing mower, there are typically three gearboxes (center, left wing, right wing), plus a power divider gearbox that splits the main shaft power into three outputs.

The Critical Connection
These two components must be precisely matched in terms of spline size, torque rating, and rotational speed. A PTO shaft for flexwing mower that delivers 540 RPM must connect to gearboxes designed for that input speed. The spline interface (such as the 1.375"-6 or 1.750"-20 connections used in Bush Hog models) must be identical on both the shaft output and gearbox input. When replacing either component, always verify compatibility with the other. CMN Transmission supplies both tractor PTO shafts and rotary cutter gearboxes, allowing customers to source matched components from a single supplier for guaranteed compatibility and simplified after-sales support.

अक्सर पूछे जाने वाले प्रश्न

Q: What PTO shaft fits a Bush Hog 2215 flexwing mower?
A: The Bush Hog 2215 requires a complete driveline assembly consisting of a main shaft (CAT4 or CAT5 constant velocity), a center shaft (CAT4), and two wing shafts (CAT4 with two-disc clutch). CMN Transmission's PTO shaft for Bush Hog flexwing mowers is engineered as a direct replacement and is available in all three common tractor spline sizes: 1.375"-6, 1.375"-21, and 1.750"-20.

Q: Is this PTO shaft compatible with 540 RPM and 1000 RPM tractors?
A: This driveline is designed for 540 PTO shaft speed operation. Bush Hog flexwing mowers in the 1812 through 2815 series are rated for 540 RPM. If your tractor features a dual-speed PTO, set it to 540 RPM mode only. Running the mower at 1000 RPM PTO shaft speed will exceed the mower's design limits and can cause dangerous blade over-speed and driveline failure.

Q: Can this PTO drive shaft replace a Bondioli & Pavesi or Walterscheid shaft?
A: Yes. This shaft is manufactured as a direct replacement of Bondioli & Pavesi PTO shaft assemblies and Walterscheid drivelines commonly supplied as OEM equipment on Bush Hog flexwing mowers. All spline dimensions, shaft lengths, and clutch ratings are matched to OEM specifications. Simply confirm your tractor's spline type and mower model number to ensure correct fitment.

Q: What is the torque rating of the slip clutch on this PTO shaft?
A: The wing shafts feature a CAT4 two-disc slip clutch PTO shaft rated at 1200 Nm (approximately 885 ft-lbs) of torque. This rating provides reliable overload protection during normal flexwing mowing operations. The clutch is self-resetting, meaning it automatically re-engages after the overload condition passes, unlike shear bolt PTO shaft designs that require manual bolt replacement after each activation.

Q: How do I determine the correct PTO shaft size for my tractor?
A: To determine the correct PTO shaft sizes, measure your tractor's PTO stub shaft diameter and count the splines. A 1.375" diameter with 6 splines indicates the 1.375"-6 profile, 21 splines indicates 1.375"-21, and a 1.750" diameter with 20 splines indicates the 1.750"-20 profile. Your tractor's operator manual also lists this specification. If you are unsure, contact CMN Transmission with your tractor make, model, and year for a confirmed match.

Q: Does CMN Transmission offer custom PTO shaft lengths?
A: Yes. CMN Transmission supports full custom PTO shaft manufacturing. If your tractor and mower combination requires a non-standard closed or open length due to an extended drawbar, specialized hitch, or unique mounting configuration, the engineering team can produce PTO shaft tubing cut and splined to your exact measurements. Provide your minimum and maximum working distances for an accurate quotation.

प्रश्न: मुझे पीटीओ शाफ्ट के यूनिवर्सल जॉइंट्स में कितनी बार ग्रीस लगाना चाहिए?
A: Grease each PTO shaft universal joint and the telescoping tube profile every 8 to 10 hours of operation, or at the start of each mowing day, whichever comes first. Use a high-quality lithium-based EP2 grease. Pump grease into each zerk fitting until fresh grease appears at the bearing seals. Regular greasing is the single most important maintenance task for extending the life of your agricultural PTO shaft and preventing premature cross bearing failure.

Q: What is the difference between CAT4 and CAT5 PTO shafts?
A: CAT4 PTO drive shafts (S6 series) are rated for tractors producing up to 60 HP at the PTO output, while CAT5 (S8 series) handles up to 90 HP. The CAT5 uses larger cross bearings, heavier PTO shaft tube sections, and wider yokes to handle the increased torque. Selecting the correct category ensures your driveline can safely transmit the full power of your tractor to the mower without risk of mechanical failure.

Q: Can I order just the wing shafts or center shaft separately?
A: Yes. While CMN Transmission offers complete driveline assemblies, individual PTO shaft parts including the main shaft, center shaft, wing shafts, PTO shaft yoke assemblies, cross bearings, clutch discs, and PTO shaft cover guards can all be ordered separately. This is particularly useful when only one section of the driveline requires replacement while the remaining components are still in good condition.

Q: Does this PTO shaft come with safety guard tubes?
A: Yes. Every heavy duty PTO shaft assembly from CMN Transmission includes full-length safety guard tubes with bearing-supported free rotation. The PTO shaft cover guards prevent accidental contact with the rotating shaft and meet international agricultural equipment safety standards. Guard anchor chains are included to prevent the guard from rotating with the shaft. Never operate a PTO driveline without the guards properly installed and secured.

मार्कस हॉलिंग्सवर्थ, फार्म मैनेजर, संयुक्त राज्य अमेरिका
"Been running a Bush Hog 2215 on our 320-acre cattle operation for about six years now, and we finally needed a full driveline replacement after the original shafts wore through. Ordered the complete CAT5 S8 set from CMN Transmission with the 1.750-20 tractor spline. The fit was spot on to our power divider and both wing gearboxes, no shimming or adapters needed. We are roughly 220 hours into the new shafts this season, cutting heavy Johnson grass and some pretty thick broom sedge along the creek bottoms. Everything runs smooth, no vibration, and the guards feel a lot sturdier than what came stock. Very happy with this purchase."

Craig Donovan, Station Manager, Australia
"We operate a large-scale grazing station in Queensland and needed replacement wing shafts for our Bush Hog 2810 flexwing. Tried a couple of local aftermarket options first, but the U-joints kept failing after 60 or 70 hours. The CMN CAT4 wing shafts with the two-disc slip clutch have been running since early last year, probably close to 400 hours now with zero issues. The slip clutch has saved us a few times when we hit stumps hidden in the scrub. Shipping to Australia took about three weeks, which was quicker than I expected for an international order. Would recommend to other station operators here."

Daniel Tremblay, Fleet Supervisor, Canada
"I manage a fleet of mowing tractors for our county road department in southern Ontario. We run Bush Hog 1815 mowers and go through PTO shafts regularly because of the daily abuse on roadsides. CMN Transmission offered us a volume quote that was significantly below what we were paying our previous supplier for comparable Bondioli and Pavesi replacements. The quality is every bit as good. We have installed their shafts on four of our six machines so far. The service team answered all my technical questions about spline compatibility before I placed the order, which gave me confidence in the purchase."

Klaus Behrens, Farm Owner, Germany
"Wir betreiben einen 180 Hektar Betrieb in Niedersachsen und haben den kompletten Gelenkwellensatz fur unseren Bush Hog 2212 bestellt. I will write in English for this review. The CMN shaft replaced our old Walterscheid unit that had been on the mower for about five seasons. Fit was precise on the 1.375-21 spline. What impressed me most was the packaging. Every shaft was individually wrapped, all hardware was labeled, and the installation diagram was included. After about 150 operating hours cutting grass and clover aftermath, the driveline is running perfectly. German customers can trust the quality here."

Pierre-Luc Garnier, Cooperative Director, France
"Our agricultural cooperative near Bordeaux uses Bush Hog flexwing mowers for vineyard inter-row maintenance and we needed a replacement center shaft and main shaft for our 1812 model. CMN Transmission's sales team was very responsive, they provided a CAD drawing of the shaft assembly so I could verify dimensions before ordering. The shaft arrived in 18 days to France. Quality of the CV joint is excellent and the greasing points are well positioned for easy maintenance. We have been running it for about three months through the growing season and it performs exactly as the original. Good value for what you get."

Shane Whitaker, Contract Mower, New Zealand
"I run a contract mowing business in the Waikato region and put serious hours on our Bush Hog 2815 flexwing every week. The previous aftermarket shafts I bought locally lasted barely two seasons before the telescoping tubes started jamming. Switched to CMN Transmission after finding them online. The CAT5 main shaft and wing shafts have been solid through a full season of dairy pasture topping, easily 500 plus hours. The slip clutch saved the driveline twice when we hit buried concrete in an old paddock. Pricing was very fair even with freight to New Zealand. Already ordered a spare set."

Roberto Mendes, Farm Director, Brazil
"Our fazenda in Goias state needed a complete PTO shaft set for the Bush Hog 2215 we use for soybean stalk shredding after harvest. Import process to Brazil can be complicated, but CMN Transmission provided all the export documentation and certificates we needed for customs clearance. The shafts arrived well-packed in a wooden crate. We installed the CAT4 set with 1.375-6 spline and have been running hard through soybean and corn residue for about two months. Build quality feels comparable to the Bondioli Pavesi units we used before at a much better price point. The clutch engagement is smooth and predictable."

Johan van der Merwe, Grain Farmer, South Africa
"We bought the full driveline kit for our Bush Hog 2810 mower on our wheat and barley operation in the Free State province. What sold me was the fact that CMN offered OEM-level quality with actual factory-direct support. When I had a question about the center shaft length for our specific model, I got an answer within a few hours, not days like some other suppliers. The shafts have been through one full season of stubble management, around 280 hours, and everything is holding up well. The guard tubes are thick and properly balanced, no rattling or rubbing. Good product, good people to deal with."

Padraig O'Sullivan, Mixed Farmer, Ireland
"I purchased the CAT4 main shaft and both wing shafts for a Bush Hog 1812 that we use on our 200-acre mixed farm in County Cork. We mainly cut rough pasture and rushes along field margins. Delivery to Ireland took about two and a half weeks, which was reasonable. Installation was straightforward, the splines lined up perfectly with our Massey Ferguson 135 HP tractor's 1.375-6 PTO. We are about 180 hours in and the shaft runs true with no vibration at all. The two-disc clutch is a nice feature compared to the shear bolt setup on our old shaft, saves time not having to replace bolts after every impact. Really pleased overall."
