Features of PTO Drive Shaft for Woods Batwing Mower

1. Constant Velocity Joint Design
Unlike standard PTO shaft universal joint assemblies that produce pulsating torque at high angles, this PTO driveline shaft features a constant velocity (CV) joint that delivers uniform rotational speed throughout the full operating range. This significantly reduces vibration, extends the service life of the mower gearbox, and provides smoother cutting performance even on uneven terrain where the tractor and implement are not perfectly aligned.

2. Heavy Duty PTO Shaft Tube Construction
The PTO shaft tube is manufactured from high-strength alloy steel with precision-machined profiles to ensure tight telescoping tolerances. This heavy duty PTO shaft construction resists bending and fatigue under sustained high-torque loads, making it ideal for commercial operators who run their Woods batwing mowers for extended hours during peak mowing season. The PTO shaft tubing is treated with corrosion-resistant coatings for long-term outdoor use.

3. Multiple Spline Configurations
This PTO shaft for batwing mower applications comes in three tractor spline options: 1.375"-6 spline, 1.375"-21 spline, and 1.750"-20 spline. Each configuration is available across Cat 4, Cat 5, and Cat 6 categories, covering power ratings from 60 HP to 184 HP. This means there is no need for an additional PTO shaft adapter when matching the shaft to your specific tractor, ensuring a direct bolt-on installation with zero modifications required.

4. Optional Slip Clutch Protection
For operators working in fields with hidden debris, stumps, or rocky conditions, this PTO shaft with slip clutch option provides critical overload protection. The slip clutch PTO shaft disengages momentarily when the driveline encounters a sudden spike in resistance, protecting both the tractor PTO output and the mower gearbox from catastrophic damage. A PTO shaft shear bolt configuration is also available as an alternative torque-limiting solution for budget-conscious operations.

5. Direct Replacement of Weasler & Woods OEM Shafts
This replacement of Woods PTO shaft is designed to match the original Weasler and Woods OEM shaft dimensions exactly, including yoke bore sizes, cross-journal specifications, and overall shaft length. The PTO shaft yoke profiles are CNC-machined to OEM tolerances, so you can remove the worn original unit and install this custom PTO shaft replacement without any shimming, welding, or adapter brackets. It is a true drop-in solution.

6. Full Safety Guard System
Every agricultural PTO shaft from CMN Transmission ships with a complete PTO shaft cover and safety guard assembly that meets CE safety standards. The guard tubes rotate freely around the shaft during operation, preventing clothing or materials from wrapping around the spinning driveline. The guards are constructed from impact-resistant polymer with UV stabilizers to withstand years of sun exposure without cracking or becoming brittle, ensuring operator safety remains uncompromised throughout the product's lifespan.

How Does the Tractor PTO Shaft for Batwing Mower Work?

A tractor PTO drive shaft is the mechanical link that transfers rotational power from the tractor's power take-off (PTO) output stub to the implement's input shaft. In the case of a Woods batwing mower, the PTO shaft tractor connection drives the center gearbox, which in turn distributes power through additional drivelines to the wing gearboxes that spin the cutting blades. The entire system relies on precise torque transmission at a fixed rotational speed, either 540 RPM or 1000 RPM depending on the tractor's PTO configuration.

The working process begins when the operator engages the tractor's PTO clutch. The PTO output stub, which features a standardized spline pattern (such as 1.375"-6 for 540 RPM or 1.375"-21 for 1000 rpm PTO shaft systems), begins to rotate. The PTO shaft yoke on the tractor end of the driveline is splined to match this output stub and locks onto it, transferring rotational energy into the shaft assembly. As the shaft spins, it passes through the telescoping PTO shaft tube section, which allows the overall shaft length to change as the tractor and mower move relative to each other during turns, over hills, or across uneven ground.

At the midpoint of the shaft assembly, the constant velocity joint allows the driveline to operate at an angle without the speed fluctuations that occur with standard PTO shaft u joint (Cardan joint) configurations. In a conventional universal joint, the output speed varies sinusoidally as the shaft rotates, which creates vibration and uneven torque delivery. The CV joint in this PTO drive shaft eliminates that problem by using a ball-and-cage mechanism that maintains a 1:1 speed ratio between the input and output regardless of the joint angle, up to approximately 80 degrees total working angle.

The implement end of the PTO driveline shaft connects to the mower's center gearbox input shaft through a matching yoke and cross-journal bearing assembly. When the operator has selected the PTO shaft with slip clutch option, a friction disc pack is positioned inline with the driveline. Under normal operating conditions, the clutch pack transfers full torque. However, if the mower blades strike a solid object like a stump or a rock, the resulting torque spike causes the clutch discs to slip momentarily, absorbing the shock energy and preventing it from traveling back through the tractor PTO shaft to the tractor's transmission. Alternatively, operators using the shear bolt PTO shaft configuration rely on a sacrificial bolt that shears at a predetermined torque threshold, completely disconnecting the driveline until a new bolt is installed.

Throughout operation, the PTO shaft cover and safety guard assembly enclose the spinning shaft, preventing accidental contact. The guard tubes are mounted on bearings at each end so they remain stationary while the shaft spins inside them. This design is critical for operator safety and is required by regulatory standards in most agricultural markets worldwide.

Applications of Batwing Mower PTO Shaft

• Management von Ernterückständen
  After harvest, fields are often covered with thick stalks and residue from corn, sorghum, sunflower, and other row crops. A Woods batwing mower powered by this PTO drive shaft can efficiently shred and redistribute crop residue across wide swaths, promoting faster decomposition, improving soil nutrient cycling, and preparing the field for the next planting season. The wide cutting width of batwing mowers makes this process significantly faster than single-deck rotary cutters.
• Weidemanagement
  Maintaining healthy, productive pastures for cattle, sheep, and horse operations requires regular mowing to control weed invasion and encourage the growth of desirable grass species. This tractor PTO shaft delivers consistent power to the batwing mower, enabling operators to mow hundreds of acres per day. By keeping pasture at an optimal height, livestock forage quality improves and toxic weed species are suppressed before they can set seed and spread.
• Rasenpflege
  Municipal parks, sports complexes, corporate campuses, and large estates require routine grass cutting over extensive turf areas. The batwing mower PTO shaft enables these mowers to cover maximum acreage in minimum time, making it an economical choice for commercial grounds maintenance contractors. The constant velocity joint ensures smooth power delivery that results in a cleaner, more uniform cut height compared to drivelines that produce vibration and torque pulses.
• Weed and Light Brush Control
  Overgrown fields, vacant lots, and boundary areas can quickly become choked with invasive weeds and light brush if left unattended. A Woods batwing mower connected via this heavy duty Zapfwelle can cut through dense weed stands and saplings up to several inches in diameter, reclaiming neglected land without the need for chemical herbicides. The slip clutch PTO shaft option provides extra protection when hidden obstacles are encountered in these unimproved areas.
• Straßenrandvegetationskontrolle
  State highway departments, county road crews, and private contractors use batwing mowers to maintain clear sight lines and safe shoulders along roads and highways. The wide cutting swath and reliable PTO driveline shaft of this assembly allow operators to mow long stretches of roadside vegetation efficiently. Because these operations often involve uneven ditches and sloped shoulders, the constant velocity joint's ability to handle wide operating angles is especially valuable.
• Obst- und Weinbergsmanagement
  In orchard and vineyard environments, controlling ground cover between tree and vine rows is essential for pest management, irrigation efficiency, and harvest access. A compact tractor equipped with this 540 PTO shaft can power a batwing mower through narrow inter-row spaces, cutting grass and weeds without disturbing the root zones of fruit trees or grapevines. This mechanical weed control method reduces dependence on herbicides, supporting integrated pest management (IPM) programs.
• Reihenkulturstängel-Häckseln
  Following the harvest of row crops such as cotton, corn, or soybeans, tough stalks remain standing in the field and can interfere with tillage operations, harbor overwintering pests, and slow the breakdown of organic matter. A Woods batwing mower driven by this agricultural PTO shaft shreds these stalks close to ground level, accelerating decomposition and enabling cleaner seedbed preparation. The high-HP rating options (up to 184 HP at 1000 RPM) ensure the driveline can handle the heavy load of shredding thick, dry stalks across large acreages without overheating or excessive wear.

Batwing Mower PTO Drive Shaft Installation Steps

Step 1: Safety Preparation.
Before beginning installation, park the tractor on level ground, set the parking brake, and shut off the engine. Disengage the PTO lever and wait for all rotating components to come to a complete stop. Remove the key from the ignition to prevent accidental startup. If you are replacing an existing PTO shaft parts assembly, allow the old shaft to cool if it has been recently operated, as cross-journal bearings and yokes can retain significant heat after use.

Step 2: Remove the Old PTO Shaft.
Disconnect the old tractor PTO shaft from the mower's input shaft first. Release the lock collar or retaining pin on the implement-end yoke and slide the yoke off the mower gearbox input spline. Then move to the tractor end and release the lock collar from the tractor PTO output stub. Carefully pull the shaft assembly free and set it aside. Inspect the tractor PTO output stub and the mower gearbox input shaft for any signs of spline wear, damage, or debris. Clean both spline surfaces thoroughly with a wire brush and apply a thin coat of anti-seize compound or PTO spline grease.

Step 3: Verify Shaft Length and Configuration.
Before installing the new PTO drive shaft, extend the telescoping tube section to its approximate working length by holding the tractor-end half and pulling the implement-end half outward. Compare this length to the distance between the tractor PTO output stub and the mower gearbox input shaft with the mower at its normal operating height and three-point hitch position. The shaft should have adequate overlap in the telescoping section (minimum 1/3 overlap is recommended) at full extension and should not bottom out when the mower is raised for transport. Verify that you have the correct PTO shaft sizes and spline configuration (1.375"-6, 1.375"-21, or 1.750"-20) for your specific tractor.

Step 4: Connect the Implement End First.
Slide the implement-end PTO shaft yoke onto the mower gearbox input spline. Push it firmly until the lock collar or retaining pin clicks into the groove on the input shaft. Verify that the connection is secure by pulling back on the yoke; it should not slide off. If the yoke feels excessively tight or will not slide on, check for burrs on the spline and clean or lightly file as needed. Do not force the connection.

Step 5: Connect the Tractor End.
With the implement end secured, align the tractor-end yoke spline with the tractor PTO output stub. Slide the yoke onto the stub and engage the lock collar. Give the shaft a firm pull to confirm it is locked in place. At this point, manually rotate the shaft by hand to verify that it turns freely without binding, grinding, or excessive play. Check that the PTO shaft cover guard tubes spin freely around the shaft and are properly anchored at both ends.

Step 6: Final Check and Test Run.
Start the tractor engine and bring it to idle speed. Slowly engage the PTO at the lowest RPM setting and observe the shaft for any wobble, vibration, or unusual noise. Gradually increase PTO speed to the rated operating RPM (540 or 1000) and listen for smooth, consistent operation. Observe the PTO shaft u joint areas for any signs of binding. Disengage the PTO, shut down the tractor, and perform one final visual inspection of all connections, guard positions, and lock collars before putting the mower into service.

Maintenance Tip for Tractor PTO Drive Shaft

1. Grease Cross-Journal Bearings Regularly
The PTO shaft u joint cross-journal bearings are the most critical lubrication points on the driveline. Apply high-quality EP (extreme pressure) grease through the zerk fittings on each bearing cap every 8 to 10 operating hours, or before each day of heavy use. Proper greasing prevents premature wear of the needle bearings inside the caps and avoids the costly replacement of the entire PTO shaft universal joint assembly.

2. Lubricate Telescoping Tube Section
The telescoping PTO shaft tube section should be greased periodically to ensure smooth extension and retraction. Separate the inner and outer tubes, clean off old grease and debris, and apply a fresh coat of multi-purpose grease to the spline profiles. Reassemble and cycle the tubes several times to distribute the lubricant evenly. Neglecting this maintenance point can lead to seized tubes that restrict the shaft's ability to telescope, causing excessive stress on the joints.

3. Inspect Safety Guards and Covers
Check the PTO shaft cover and guard tubes before every use. Ensure the guards rotate freely, are not cracked or broken, and are securely attached at both tractor and implement ends. Replace any damaged guard components immediately. Operating a tractor PTO shaft without proper guards is extremely dangerous and is prohibited by occupational safety regulations in most countries. Never remove guards for convenience or to clear a jam without first shutting down the tractor and disengaging the PTO.

4. Check for Wear and Play
Periodically grip the shaft near each PTO shaft universal joint and try to rock it. Any noticeable play or clicking indicates worn cross-journal bearings that need replacement. Also inspect the PTO shaft yoke bores for elongation or spline wear. Catching these issues early prevents a minor wear problem from escalating into a catastrophic driveline failure that could damage the tractor PTO output or the mower gearbox. Replace worn PTO shaft parts promptly.

5. Maintain Slip Clutch or Shear Bolt Mechanism
If your driveline includes a slip clutch PTO shaft, check the clutch plate friction surfaces and spring tension periodically. Worn friction plates reduce the clutch's torque capacity, allowing it to slip during normal operation and generating excessive heat. For shear bolt PTO shaft configurations, always carry spare shear bolts of the correct grade and diameter. Never substitute hardened bolts for factory-specified shear bolts, as this defeats the overload protection and risks damaging the driveline or gearbox.

6. Seasonal Storage
At the end of the mowing season, remove the PTO drive shaft from the mower and tractor. Clean the entire assembly thoroughly, grease all lubrication points, and apply a light coat of rust-preventive oil to exposed metal surfaces. Store the shaft horizontally on a rack in a dry, sheltered location. Do not leave the shaft connected to the mower during off-season storage, as moisture can accumulate in the spline joints and promote corrosion that will make disassembly difficult when the next season begins.

Troubleshooting Common PTO Driveline Shaft Issues

• Excessive Vibration During Operation
  If you notice significant vibration when the PTO shaft is engaged, the most common cause is worn cross-journal bearings in the PTO shaft u joint assemblies. Shut down the tractor, disengage the PTO, and manually check each joint for play by gripping the shaft on either side of the joint and trying to rock it. If play is detected, the cross-journal bearing kit needs to be replaced. Other causes of vibration include a bent PTO shaft tube, mismatched shaft halves (inner and outer tubes from different manufacturers), or an incorrect operating angle that exceeds the CV joint's rated range. Verify that the tractor drawbar height and three-point hitch position are set correctly for the mower model.
• Shaft Will Not Telescope Smoothly
  If the telescoping section of the PTO driveline shaft feels stiff, jerky, or refuses to extend or retract, the most likely cause is dried-out or contaminated grease on the internal spline profiles. Separate the two tube halves, clean the spline surfaces with a solvent and wire brush, inspect for bent or damaged spline teeth, and re-grease with fresh multi-purpose grease. If the tubes are severely scored or the spline teeth are heavily worn, the PTO shaft tubing section should be replaced to prevent the shaft from separating during operation, which is an extremely hazardous situation.
• Slip Clutch Slipping Under Normal Load
  If the PTO shaft with slip clutch is slipping during routine mowing without any impact event, the friction discs inside the clutch pack are likely worn beyond their service limit. Remove the clutch assembly, measure the friction disc thickness, and compare against the manufacturer's minimum specification. Replace worn discs as a complete set to ensure even torque transfer. Also check the clutch spring compression; weakened springs reduce clamping force and allow premature slipping. If the shear pin PTO shaft variant is shearing bolts frequently during normal operation, verify that the correct grade and size of shear bolt is being used and that the mower blades are not dull or damaged, which would increase the cutting load beyond normal levels.
• Unusual Noise from Yoke or Joint Area
  Clicking, popping, or grinding sounds emanating from the PTO shaft yoke or joint area typically indicate advanced bearing wear, a loose yoke retaining mechanism, or a cracked yoke ear. Stop operation immediately if these sounds are present. Inspect the yoke bore for cracks and the lock collar or pin for proper engagement. A loose yoke can cause the shaft to detach from the tractor or mower during operation, creating an extremely dangerous whipping hazard. Replace any cracked or deformed yokes immediately and do not attempt to weld-repair them, as welding alters the metallurgical properties and can lead to sudden failure under load.
• Shaft Runs Hot
  If the PTO drive shaft or its joints become excessively hot during operation, the likely causes are insufficient lubrication, excessive operating angle, or binding in the telescoping section. Check that all grease fittings are functional and that grease is reaching the bearing surfaces (you should see a small amount of fresh grease emerge from the bearing cap seals when greasing). Verify the operating angle is within specification and that the shaft is not bottoming out in the telescoping section, which would prevent the joint from articulating properly and generate severe heat buildup.

Batwing Mower PTO Shaft & Rotary Cutter Gearbox

The batwing mower PTO shaft is the rotating driveline assembly that connects the tractor's PTO output to the mower's center gearbox. It is responsible for transmitting all of the rotational energy needed to power the cutting blades across the mower's full width. In a batwing (flexwing) configuration, the main PTO shaft drives the center gearbox, which then uses secondary drivelines to power the two wing gearboxes. The quality, balance, and durability of the PTO shaft directly affect the performance, safety, and longevity of the entire mowing system. A worn or poorly manufactured PTO driveline shaft introduces vibration that accelerates wear on every downstream component, from gearbox bearings to blade spindles.

The rotary cutter gearbox is the speed-reduction unit mounted on top of the mower deck that receives input from the PTO drive shaft and converts horizontal rotational input into vertical output that spins the cutting blades. In a Woods batwing mower, there are typically three gearboxes: one center unit and two wing units. Each gearbox uses a set of spiral bevel gears to redirect the power flow 90 degrees while simultaneously reducing the shaft speed and increasing torque to deliver the cutting force needed to shred heavy vegetation. The gearbox housing is filled with gear oil and must be maintained at the correct level to prevent gear and bearing damage.

The PTO shaft for batwing mower and the rotary cutter gearbox form an integrated power transmission system. The PTO shaft is the input device that delivers raw rotational power from the tractor, and the gearbox is the conversion device that transforms that power into usable cutting force. Without a properly functioning tractor PTO drive shaft, the gearbox receives no power and the mower sits idle. Conversely, without a properly maintained gearbox, even the best heavy duty PTO shaft cannot produce useful cutting output. When specifying replacement components, it is important to match the PTO shaft's torque rating to the gearbox's input capacity. Over-powering a gearbox with a shaft rated far above its design limit can accelerate gear wear, while under-powering with an inadequate shaft creates overload conditions that damage both the shaft and gearbox. CMN Transmission offers both PTO drive shafts and rotary cutter gearboxes, enabling customers to source matched, compatible components from a single supplier for optimal performance and simplified ordering.

A: This PTO shaft for Woods batwing mowers is available in Cat 4, Cat 5, and Cat 6 sizes with three tractor spline configurations: 1.375"-6 spline for standard 540 RPM tractors, 1.375"-21 spline for 1000 RPM tractors, and 1.750"-20 spline. Power ratings range from 60 HP at 540 RPM up to 184 HP at 1000 RPM, covering most mid-range to high-horsepower tractors used with these mower models.

Q: Is this PTO drive shaft a direct replacement of Weasler PTO shaft assemblies?
A: Yes. This PTO drive shaft is engineered as a direct replacement of Weasler PTO shaft assemblies and also serves as a replacement of Woods PTO shaft units originally installed on these batwing mower models. All yoke dimensions, spline profiles, cross-journal specifications, and overall shaft lengths match the OEM specifications, so no adapters, shimming, or modifications are required for installation.

Q: Should I choose a 540 PTO shaft or a 1000 PTO shaft for my batwing mower?
A: The choice between a 540 PTO shaft and a 1000 rpm PTO shaft depends on your tractor's PTO output speed. Most compact and utility tractors use a 540 RPM PTO, while larger agricultural tractors often feature a 1000 RPM PTO or a switchable 540/1000 RPM PTO. Check your tractor operator's manual to confirm the PTO output speed and spline count before ordering. Using the wrong speed configuration can damage both the shaft and the mower gearbox.

Q: What is the difference between a PTO shaft with slip clutch and a shear bolt PTO shaft?
A: A PTO shaft with slip clutch uses a spring-loaded friction disc pack that slips momentarily when torque exceeds a preset threshold, then automatically re-engages once the overload clears. A shear bolt PTO shaft uses a sacrificial bolt that breaks at a specific torque level, fully disconnecting the driveline until a new bolt is installed. The slip clutch is more convenient for operations where impacts are frequent, while the shear bolt is a simpler, more economical solution for occasional overload protection.

Q: Do I need a PTO shaft adapter to fit this shaft to my tractor?
A: In most cases, no PTO shaft adapter is needed because this shaft is available in the three most common North American tractor PTO spline sizes (1.375"-6, 1.375"-21, and 1.750"-20). As long as you order the correct spline configuration that matches your tractor's PTO output stub, the shaft will connect directly. If your tractor has a non-standard or metric PTO spline, contact our sales team to discuss custom PTO shaft options.

Q: How often should I grease the PTO shaft universal joint and cross bearings?
A: The PTO shaft universal joint cross-journal bearings should be greased with EP-grade grease every 8 to 10 operating hours under normal conditions, or more frequently if operating in dusty, wet, or extremely hot environments. The telescoping PTO shaft tube spline should be cleaned and re-greased at least once per month during the active mowing season. Consistent lubrication is the single most important factor in extending the service life of your tractor PTO shafts.

Kundenrezensionen

Jake Morrison, Ranch Foreman, United States
"We run a Woods 3180 batwing on a 320-acre cattle ranch in central Texas and needed a replacement PTO shaft after our original Weasler unit developed bad U-joint play at around 600 hours. Ordered the Cat 4 with 1.375"-6 spline from CMN Transmission and the fit was dead on. Slid right onto the tractor PTO stub without any fuss. We are about 200 hours into the new shaft now, cutting Bahia grass and some pretty nasty mesquite regrowth along our fence lines, and it is running smooth and quiet. The safety guard quality is noticeably better than the old one. Solid purchase, no complaints."

Darren Whitfield, Fleet Supervisor, Australia
"I manage a municipal road maintenance crew in Queensland, and we use three Woods BW180 batwing mowers for roadside vegetation control. We switched to CMN Transmission PTO shafts last year when one of our Walterscheid units needed replacing and the lead time from the dealer was over eight weeks. CMN shipped to Brisbane in 12 days. The shaft has been brilliant. Smooth delivery, well-packed, and the 1000 RPM configuration with 1.375"-21 spline matched our John Deere tractors perfectly. We have since ordered two more for our other machines."

Grant Pederson, Farm Owner, Canada
"Bought this for our Woods 2162 batwing that we use on a 500-hectare grain farm in Saskatchewan for post-harvest stalk shredding. The Cat 5 configuration handles the heavy corn stalk residue without any issue, and the constant velocity joint really does make a difference compared to the standard Cardan joint shaft we had before. Much less vibration in the cab. My only minor gripe is that the paint finish on the guard tubes started showing rust spots after about four months outdoors, but that is cosmetic and does not affect function at all. For the price compared to OEM, this is excellent value."

Ricardo Almeida, Operations Director, Brazil
"We operate a contract mowing business in Minas Gerais and run Woods HD315 batwing mowers for sugarcane stalk shredding on large estates. Getting OEM parts here in Brazil is slow and expensive. A colleague recommended CMN Transmission. Ordering was straightforward, the sales team spoke clear English, answered all my spline questions within 24 hours, and sent dimensional drawings before we committed. The shaft arrived in 18 days via sea freight to Santos port. Quality is on par with the Weasler original. We have two shafts running now, both past 350 hours with zero issues. Very happy with this supplier."

Pieter van der Merwe, Farm Manager, South Africa
"We purchased the PTO shaft with slip clutch option for our Woods MD315 running on a New Holland T6.180. On our farm outside Pretoria we mow thick Guinea grass and occasionally hit termite mounds that are rock hard. The slip clutch has already saved us once when we clipped a buried concrete post. The shaft stopped, the clutch slipped, and nothing broke. Re-engaged and kept going. That alone justified the extra cost. Build quality is solid all around, the U-joints feel tight, and the telescoping section is smooth. Would recommend to any farmer running a batwing in rough conditions."

Thomas Brandt, Contractor, Germany
"Wir betreiben einen Lohnunternehmer-Betrieb in Niedersachsen and use Woods 3240 mowers for grass maintenance on airfield perimeters and levee banks. We needed a Cat 6 shaft rated for 184 HP at 1000 RPM to match our Fendt 724 Vario. CMN Transmission had exactly the right configuration in stock. Delivery to Hamburg took about three weeks, which is reasonable for international freight. The shaft is well-made, the CV joint is smooth, and the overall balance is good. No vibration at all, even at full speed. German aftermarket dealers could not match this price-quality ratio. We will order again."

Bruce Callahan, Station Manager, New Zealand
"I bought this as a replacement for a worn PTO shaft on our Woods BW126 that we use to mow paddocks on a sheep station in Canterbury. The 540 RPM Cat 4 version was what we needed, and it fit our Massey Ferguson 5455 without any adapter. Installation took about 20 minutes. The shaft itself feels well-built and the grease fittings are positioned where you can actually reach them, which is a nice detail. Shipping to New Zealand took a bit longer than I hoped, about four weeks door to door, but that is partly our remote location. Product quality is good for the money."

Harpreet Singh, Farm Owner, India
"We are a large-scale wheat and barley operation in Punjab, and after harvest we need to shred massive amounts of stubble across 2,000 acres before the next planting window opens. Our Woods 3180 batwing runs 10 to 12 hours per day during that period. The CMN PTO shaft has held up beautifully through two full post-harvest seasons now, probably close to 500 hours of hard use. We went with the Cat 5, 1000 RPM, 1.375"-21 spline configuration. The sales team even helped us verify the correct specs for our Sonalika tractor. Pricing was very fair compared to importing Weasler originals through a dealer here. Highly recommended."

James Whitaker, Parts Manager, United Kingdom
"We supply agricultural equipment and parts to farms across the Thames Valley and Home Counties. A customer asked us to source a replacement PTO shaft for his Woods BW180 at a competitive price, so we tried CMN Transmission for the first time. Communication was excellent. They responded to our initial enquiry within a few hours, provided a detailed quotation with technical specifications and photos, and shipped from their warehouse to our depot in Oxfordshire in 16 days. Our customer reported that the shaft fitted perfectly and has been running well for about six months now. We have since added CMN to our regular supplier list for PTO shaft parts and driveline components."
