Features of PTO Drive Shaft for John Deere Square Baler
1. Constant Velocity Design
Unlike standard cross-joint PTO shafts, the constant velocity joint on this PTO shaft for square baler maintains uniform rotational speed regardless of operating angle. This reduces vibration transmitted to the baler gearbox, extends the life of knotters and pickup tines, and provides smoother bale formation even on uneven terrain.
2. Direct OEM Replacement Fit
Engineered as a drop-in replacement of John Deere PTO shaft assemblies, this unit directly replaces Weasler 35N/55N CV and Walterscheid 2480/2580 series shafts. Compatible with 1.375-6, 1.375-21, and 1.750-20 tractor spline outputs, no PTO shaft adapter or modification is needed for installation on your John Deere 100 square baler.
3. Heavy-Duty PTO Shaft Tube
The PTO shaft tube is manufactured from precision-drawn alloy steel PTO shaft tubing with a thick wall cross-section to handle the sustained high-torque loads of square baling. The telescoping tube profile allows length adjustment during tight turns and transport, preventing damage to the PTO shaft yoke and tractor PTO stub.
4. Integrated Safety Guard
Every shaft ships with a full-length PTO shaft cover (guard tube) that meets CE safety standards. The free-spinning cone and bell-shaped shields at each end prevent clothing or debris from catching on the rotating PTO driveline shaft, keeping operators safe during field operations and meeting compliance requirements for agricultural machinery regulations.
5. Shear Bolt Overload Protection
The shear bolt PTO shaft protection mechanism uses a calibrated PTO shaft shear bolt that breaks cleanly when torque exceeds safe operating limits, for example when the baler encounters a foreign object or the bale chamber becomes over-packed. This sacrificial bolt protects the more expensive gearbox, PTO shaft u joint, and driveline components from catastrophic failure.
6. Precision Universal Joints
Each PTO shaft universal joint is assembled with needle-bearing crosses, heat-treated yoke ears, and zerk grease fittings for easy lubrication. These high-grade PTO shaft u joint assemblies provide a wider operating angle range and significantly longer service life compared to economy aftermarket joints, reducing downtime during critical baling windows.
How Does the Tractor PTO Shaft for Square Baler Work
A PTO shaft (power take-off shaft) serves as the mechanical link between a tractor's engine and an attached implement. When the operator engages the tractor's PTO clutch, engine power is routed through the transmission to the rear PTO stub shaft, which rotates at a standardized speed. For the John Deere Square Baler 100, this tractor PTO shaft typically operates at 540 RPM or 1000 RPM depending on the tractor configuration and the specific PTO shaft sizes fitted.
The splined input yoke on the tractor end of the PTO drive shaft slides onto the tractor's PTO stub and is locked in place by the spring-loaded collar. As the stub turns, rotational torque passes through the first universal joint, travels down the telescoping PTO shaft tube, and reaches the constant velocity joint at the implement end. The CV joint is the critical component that differentiates this design from a standard tractor PTO drive shaft: while a conventional double-cardan arrangement creates cyclical speed variation at operating angles above a few degrees, the CV joint maintains a 1:1 speed ratio between the input and output.
This constant output velocity is particularly important for square balers because the plunger mechanism, knotters, and feed forks all depend on precisely timed rotational input. Speed fluctuations from conventional joints can cause mistied knots, uneven bale density, and accelerated wear on the baler's internal gearing. The CV joint eliminates these issues by using a ball-and-cage design that compensates for angular displacement in real time.
The telescoping tube section allows the PTO driveline shaft to lengthen and shorten as the baler follows the tractor through turns and terrain changes. Inside the tube, a lemon-shaped or star-shaped profile transmits torque while allowing axial sliding. At the implement end, the output yoke connects to the baler's input shaft, typically through the baler gearbox, which further reduces the speed and increases the torque to drive the heavy plunger flywheel. The integrated shear pin PTO shaft clutch sits between the CV joint and the output yoke, acting as a mechanical fuse. If the baler's bale chamber jams or the plunger encounters an obstruction, the shear bolt fractures before damage can propagate upstream to the PTO shaft universal joint or tractor gearbox, making it a critical safety and cost-saving feature.
Applications of Square Baler PTO Shaft
- Hay
Mixed grass and legume hay is the most common material processed through square balers. The PTO drive shaft delivers steady power to compact loose hay windrows into tight, uniform bales that are easy to stack, transport, and feed to livestock throughout the winter months. - Silage
When baling haylage or pre-wilted silage, the high-moisture crop puts extra torque demand on the driveline. This heavy duty PTO shaft with constant velocity technology maintains consistent plunger speed, ensuring tight bale density that promotes proper fermentation and minimizes spoilage in wrapped square bales. - Wheat Straw
Wheat straw is light, slippery, and difficult to compress consistently. The CV joint on this square baler PTO shaft eliminates speed pulsation at the pickup and feeder, allowing the baler to form dense, well-shaped straw bales valued for animal bedding, mulching, and industrial applications. - Rice Straw
Rice straw contains high silica content that accelerates wear on driveline components. CMN's tractor PTO shaft uses hardened spline surfaces and heat-treated universal joint components to resist abrasive wear, making it well-suited for paddies in Southeast Asia, South Asia, and other major rice-producing regions. - Corn Silage
Square-baled corn silage requires significant compaction force due to the coarse, heavy nature of chopped corn stalks. This PTO shaft for John Deere square baler delivers the sustained high torque needed to pack corn material into tight bales while the shear bolt protection guards against overload from stalks bundling in the bale chamber. - Pasture Grass
Native pasture grasses come in varying lengths and densities. The telescoping PTO shaft tube accommodates constant direction changes as the tractor follows irregular windrow patterns common on natural pastures, while the CV joint provides smooth operation at the wider angles that hilly grazing land often requires. - Alfalfa
Premium alfalfa hay demands precise bale formation to preserve leaf content and nutritional value. The constant velocity output of this PTO driveline shaft ensures the baler's feed forks and plunger operate at exact intervals, reducing leaf shatter compared to systems driven by standard cross-joint shafts that produce speed variation. - Reeds
Reed harvesting for thatching, bioenergy, or erosion-control materials subjects the baler to tough, fibrous stalks that resist compaction. The heavy duty PTO shaft from CMN Transmission is built with a reinforced tube and high-capacity universal joints to sustain the elevated torque loads reed baling demands over extended harvest periods. - Cotton
Module-building and re-baling of cotton lint or cotton gin waste is a specialized application for square balers. The PTO shaft with slip clutch overload protection is critical here because cotton material can pack unpredictably, and the shear bolt prevents driveline damage during sudden compression spikes in the bale chamber.
How to Install PTO Shaft on Your John Deere Square Baler
Step 1: Safety Preparation
Before beginning installation of the new PTO shaft for John Deere square baler, park the tractor on a level surface, set the parking brake, turn off the engine, and remove the key from the ignition. Disengage the PTO lever and wait for all rotating components to come to a complete stop. Lower the baler to the ground and block the wheels. Wear heavy work gloves and safety glasses throughout the process.
Step 2: Remove the Old Shaft
If replacing an existing tractor PTO shaft, start at the implement end. Pull back the locking collar on the yoke and slide the shaft off the baler input stub. Then move to the tractor end and repeat the process, pulling the collar and sliding the splined yoke off the tractor PTO stub shaft. Support the shaft by hand as you remove it to prevent it from dropping and damaging the universal joints or CV joint. Set the old shaft aside for comparison with the new unit.
Step 3: Verify Spline Compatibility
Before installing the new PTO drive shaft, confirm that the tractor-end yoke spline matches your tractor's PTO output. CMN Transmission offers this shaft in 1.375-6, 1.375-21, and 1.750-20 tractor spline configurations. Compare the spline count and diameter of the new yoke against the old one, or measure the tractor PTO stub directly. Also verify the implement-end spline (1.780-20 or 1.812-20 depending on the series) matches the baler gearbox input.
Step 4: Grease All Fittings
Apply NLGI #2 lithium complex grease to every zerk fitting on the PTO shaft universal joint assemblies and the CV joint. Also lightly grease the telescoping tube splines so the shaft can extend and compress freely. This step is essential before first use; running the shaft dry even briefly can score the splines and reduce service life.
Step 5: Install on the Baler First
Align the implement-end yoke with the baler's input shaft and push the PTO shaft yoke onto the splined stub until the locking collar snaps into the groove. Pull firmly on the shaft to confirm it is locked. Then move to the tractor end, extend the telescoping section as needed, and slide the tractor-end splined yoke onto the PTO stub until the collar engages.
Step 6: Final Checks
Ensure the PTO shaft cover guard tubes rotate freely and are not pinched between the shaft and any tractor or baler frame components. Check that the shaft angle does not exceed 25 degrees from horizontal in any direction. Start the tractor, engage the PTO at low idle, and visually confirm smooth rotation before increasing to operating speed. Listen for any unusual vibration or knocking sounds that might indicate a yoke alignment issue or incomplete engagement on the splines.
Maintenance Tips
1. Lubrication Schedule
Grease all PTO shaft u joint zerk fittings and the CV joint every 8 operating hours or at the start of each baling day, whichever comes first. Use NLGI #2 lithium complex grease and pump until fresh grease appears at each bearing cap seal. The telescoping PTO shaft tube splines should be cleaned and regreased every 50 hours. Over-greasing is better than under-greasing for universal joints; the excess simply purges through the seals and displaces any moisture or contaminants that have entered the bearing cups.
2. Inspect and Replace Shear Bolts
Check the PTO shaft shear bolt before every baling session. Carry at least six spare shear bolts in the tractor toolbox. Always replace broken shear bolts with the correct grade and size specified by CMN Transmission. Never substitute hardened bolts, standard Grade 5 or Grade 8 bolts, or welded repairs for the calibrated shear bolt PTO shaft mechanism. Using incorrect bolts defeats the overload protection and can result in catastrophic gearbox or driveline failure.
3. Guard Tube and Safety Shield Inspection
Verify that the PTO shaft cover and cone-shaped end shields spin freely without contacting the rotating shaft. If a guard becomes cracked, warped, or the bearing inside seizes, replace it immediately. A non-rotating guard can melt, jam, or entangle loose clothing. Check the chain or bracket that anchors the guard tube to the tractor or baler frame; it must be secure enough to prevent the guard from rotating with the shaft.
4. Telescoping Tube Maintenance
At the end of each baling season, fully extend the telescoping section and clean the inner and outer profiles with a degreaser. Inspect for scoring, cracks, or excessive wear on the spline surfaces. Apply a fresh coat of grease before reassembling and collapsing the tube. Store the PTO drive shaft horizontally on a rack or hung by both yokes to prevent the tube from telescoping open under gravity, which can let moisture collect inside the profile.
5. Universal Joint and CV Joint Care
Periodically check each PTO shaft universal joint for play by gripping the yoke and attempting to rock it. Any detectable movement indicates worn needle bearings that should be replaced before the cross fails completely. On the constant velocity joint, inspect the rubber boot for cracks, tears, or grease leakage. A torn CV boot allows dirt into the ball tracks and will destroy the joint within a few operating hours. Replace damaged boots promptly and repack with the manufacturer-specified CV grease.
6. Seasonal Storage
Before off-season storage, thoroughly clean the entire tractor PTO shaft assembly with a pressure washer and allow it to dry completely. Apply a light coat of rust-preventative oil to all unpainted metal surfaces, including spline ends and yoke ears. Store in a dry, covered area away from chemical fertilizers or acidic compounds. Avoid leaving the shaft connected to the baler during storage, as seasonal temperature changes can cause the baler frame to shift and stress the PTO shaft yoke connections.

Square Baler PTO Shaft and Square Baler Gearbox
The square baler PTO shaft and the square baler gearbox are the two most critical power transmission components in any square baling system, and they work as an integrated pair. The PTO shaft is responsible for transferring rotational energy from the tractor's PTO output to the baler, while the gearbox receives that energy and converts it into the specific speed and torque ratios required to drive the baler's internal mechanisms, including the plunger flywheel, feeder forks, and knotter assembly.
A typical square baler gearbox is a right-angle gear drive that changes the axis of rotation by 90 degrees and reduces the incoming shaft speed while multiplying torque. For instance, the 540 PTO shaft or 1000 PTO shaft delivers rotational input at 540 or 1000 RPM respectively, and the gearbox steps this down to the appropriate flywheel speed (often in the range of 80 to 120 RPM for the plunger stroke cycle). Without a properly functioning gearbox, even the best PTO driveline shaft cannot deliver usable power to the baler.
The connection point between the PTO drive shaft and the gearbox is a splined interface that must match precisely. On the John Deere 100 square baler, the implement-end spline profile (1.780-20 for the Weasler series or 1.812-20 for the Walterscheid series) mates directly with the gearbox input shaft. Any looseness, wear, or mismatch at this junction will cause vibration, accelerated gear wear, and potential failure of both components.
CMN Transmission manufactures both custom PTO shaft assemblies and square baler gearboxes, which means we can supply matched sets that are engineered to work together with guaranteed spline compatibility. When you replace a worn PTO shaft for square baler, it is always advisable to inspect the gearbox input shaft splines and bearings at the same time, as wear on one component accelerates wear on the other. Our technical team can help you determine whether a gearbox rebuild or replacement should accompany your new agricultural PTO shaft order.

Usein kysytyt kysymykset
Q: What PTO shaft sizes are available for the John Deere 100 square baler?
A: CMN Transmission offers this PTO shaft for John Deere square baler in CAT 5 (Weasler 35N CV series) and CAT 6 (Weasler 55N CV series). Both come in 48-inch overall length with a 1.780-20 implement spline. The tractor end is available in three spline configurations: 1.375-6, 1.375-21, and 1.750-20 to match different tractor PTO outputs. We also offer the Walterscheid replacement in Series 2480 (CAT 5) and 2580 (CAT 6) at 41-inch OAL.
Q: Can I use a 540 PTO shaft or a 1000 PTO shaft on this baler?
A: The John Deere 100 square baler is typically equipped to run on a 540 PTO shaft configuration. Some tractor-baler combinations may use a 1000 PTO shaft (1000 RPM) setup. The physical PTO shaft itself is mechanically the same; the RPM is determined by the tractor's PTO output setting. Always verify your tractor's PTO speed and the baler's required input speed in your operator's manual before installing.
Q: Do I need a PTO shaft adapter to fit this on my tractor?
A: No. CMN Transmission manufactures this PTO drive shaft with three tractor-end spline options (1.375-6, 1.375-21, 1.750-20) that cover the vast majority of tractors used with John Deere 100 square balers. Simply select the correct spline when ordering. If your tractor has a non-standard PTO stub, our team can advise on a PTO shaft adapter or a custom PTO shaft configuration.
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 friction discs that slip when torque exceeds a set threshold, allowing temporary overload without breaking any parts. A shear bolt PTO shaft uses a sacrificial bolt that snaps cleanly when the torque limit is exceeded, requiring a bolt replacement before resuming. The CMN shaft for the JD 100 baler uses the shear bolt system, which is standard for square baler applications because it provides a definite stop, alerting the operator to clear the jam before restarting.
Q: How often should I grease the PTO shaft universal joint and CV joint?
A: Lubricate each PTO shaft universal joint and the CV joint every 8 operating hours or at the start of each working day. Use NLGI #2 lithium complex grease and pump until fresh grease purges past the bearing seals. The telescoping PTO shaft tubing splines should also be cleaned and regreased every 50 operating hours to ensure smooth extension and retraction.
Q: Can CMN Transmission make a custom PTO shaft for non-standard baler configurations?
A: Yes. CMN Transmission specializes in custom PTO shaft solutions for agricultural, industrial, and specialty applications. If your John Deere baler setup requires a non-standard length, spline profile, or overload clutch type, our engineering team can design and manufacture a shaft to your exact specifications. Contact our sales team with your tractor model, baler model, and any existing shaft measurements for a tailored quote.
Q: What is the maximum operating angle for this constant velocity PTO shaft?
A: The constant velocity joint on this PTO shaft for square baler supports an operating angle of up to approximately 80 degrees combined articulation (sum of both joint angles). For continuous operation, we recommend keeping the working angle below 25 degrees from the centerline for maximum joint life. Always adjust your hitch height so that the tractor PTO drive shaft runs as close to horizontal as possible during baling.
Q: Does this PTO shaft replace both the Weasler 35N and Walterscheid 2480 series?
A: Yes. CMN Transmission manufactures replacement units for both the Weasler 35N/55N CV series (48-inch OAL, 1.780-20 implement spline) and the Walterscheid 2480/2580 series (41-inch OAL, 1.812-20 or 1.6875-20 implement spline). Both are available in CAT 5 and CAT 6 ratings. Make sure to select the correct series and tractor spline when placing your order for a perfect replacement of John Deere PTO shaft.
Q: How do I know when my PTO shaft yoke or U-joints need replacement?
A: Check for play by gripping the PTO shaft yoke firmly and trying to rock it relative to the tube. Any detectable movement indicates worn needle bearings in the PTO shaft u joint. Other warning signs include a clicking or popping noise during rotation, visible rust discoloration from a blown bearing seal, or grease leaking from the bearing caps. Replace worn joints promptly; a failed cross can cause the shaft to disconnect during operation, creating a serious safety hazard.
Customer Reviews
Robert McAllister, Farm Operations Director, United States
"We run three John Deere 100 balers on our 600-acre operation and have been ordering PTO shafts from CMN Transmission for the past two seasons now. The CAT 5 units with the 1.750-20 tractor spline have been a direct fit every time, no fiddling, no modifications. We put roughly 300 baling hours on the first shaft before rotating stock, and the U-joints still feel as tight as day one. The CV joint runs smooth even at the wider angles we hit on our hilly pastures. Definitely a solid alternative to the original Weasler units at a better price point. Already placed our order for two more for next season."
Markus Hoffmann, Arable Farmer, Germany
"Bought the CAT 6 replacement shaft for our Deere 100 baler after the Walterscheid 2580 we had wore through at around 400 hours. Shipping to our farm in Saxony took about 12 days from order, which was faster than expected for an overseas supplier. The packaging was proper, shaft came strapped in a wooden crate with foam padding around the CV joint. Spline fit on the gearbox input was exact, 1.6875-20 profile matched perfectly. We have been baling wheat straw and grass hay since installation, about 150 hours so far, and no issues at all. The PTO shaft cover guard rotates freely and the shear bolts are the right calibration. Very satisfied."
James O'Brien, Agricultural Contractor, Ireland
"I manage a contracting business doing hay and silage baling across three counties. We needed a reliable source for replacement tractor PTO shafts because our balers go through a lot of hours each season. Tried CMN Transmission on a recommendation from another contractor. The communication from their sales team was excellent. They helped me match the correct spline configuration for our older 1.375-6 tractor and even sent a diagram to confirm compatibility. The shaft itself is well-made, the universal joints are noticeably smoother than a budget brand I tried last year. Good value for the quality you get."
Carlos Ferreira, Dairy Farmer, Brazil
"We purchased the CAT 5 Weasler 35N CV replacement shaft for baling alfalfa on our dairy farm in Paraná. The quality surprised us considering the price. The PTO shaft tube walls are thick and the telescoping section extends and compresses very smoothly after greasing. We have used it for about 200 hours this season on second and third cut alfalfa, which is heavy and damp. No vibration issues, no knocking, the CV joint is doing its job. The safety guard is also well built with proper bearing inserts at both ends. We will order two more for our other balers."
David Thornton, Mixed Farmer, Australia
"I was a bit skeptical ordering a PTO drive shaft from a new supplier, but the experience has been positive from start to finish. I contacted their team via email and got a response with a quote within a few hours, which is uncommon in my experience. The shaft arrived in Sydney about 15 days after payment. I fitted it to our JD 100 baler in about 30 minutes, the 1.375-21 spline slid straight on. We bale mainly pasture grass and oat hay, and after a full season, the shaft shows no sign of wear. The grease fittings are well positioned and easy to access. One small suggestion: include a printed installation guide in the box."
Imran Chaudhry, Cooperative Manager, Pakistan
"Our cooperative operates over 2,000 hectares of wheat and rice production. After harvest, we bale all the straw for animal bedding and industrial use. We needed five replacement of John Deere PTO shaft units for our baler fleet. CMN Transmission offered bulk pricing that was significantly lower than the Bondioli & Pavesi distributor in Lahore. All five shafts arrived in one shipment, well packed, and every spline matched our specification. We are now over 100 hours on each shaft with zero failures. The shear bolt PTO shaft protection has already saved us twice from gearbox damage when rice straw bundles jammed the bale chamber."
Pierre Lefebvre, Livestock Farmer, France
"We have been using the CMN CAT 5 shaft on our Deere square baler for about 180 hours now, primarily baling corn silage and grass silage in Normandy. The constant velocity joint makes a noticeable difference compared to the old double-joint shaft we had before. The baler runs quieter and the knotter seems to tie more consistently, probably because the feed timing is more even. The PTO shaft universal joint bearings have shown no play at our last check. The only thing I would mention is that the guard tube bolt holes were slightly off from our tractor bracket, but a simple drill adjustment fixed it. Overall a very good product."
Andrew Mitchell, Custom Baling Operator, New Zealand
"Our farm does custom baling across the Canterbury Plains. We push our equipment hard during the summer window and cannot afford downtime. I ordered the CAT 6 (55N series) from CMN Transmission as a spare shaft and ended up putting it into service immediately after the original failed mid-season. The 48-inch overall length was correct and the 1.780-20 implement spline fit perfectly onto our baler gearbox input. What impressed me most was the build quality of the PTO shaft u joint assemblies. The needle bearings are well-packed and the zerk fittings are brass, not cheap steel ones that strip easily. Solid product."
Sipho Nkosi, Sugarcane Farmer, South Africa
"We farm sugarcane in KwaZulu-Natal and use a JD square baler to process the cane tops for cattle feed. It is very demanding work for the driveline because the material is wet, heavy, and stringy. I have used two other aftermarket PTO drive shafts before and both had U-joint failures within 120 hours. The CMN shaft has now done over 250 hours on sugarcane tops and the joints are still tight. I attribute this to the heavier bearing crosses and the proper heat treatment on the yoke ears. The slip clutch PTO shaft shear bolt system also saved us when the bale chamber blocked up during a heavy pass. Very happy with the purchase and will recommend to other farmers in our area."
