Integrated Safety Shield<\/strong> 4. Direct-Fit Replacement<\/strong> 5. Heavy-Duty PTO Shaft Tubing<\/strong> 6. Flexible Spline Configurations<\/strong> A PTO shaft (Power Take-Off shaft) is the mechanical link between a tractor’s power source and a towed or mounted implement such as a batwing mower. The tractor engine generates rotational power, which is transmitted through the tractor’s internal transmission to a splined output stub at the rear of the tractor. This tractor PTO shaft assembly connects to that stub and transfers the rotational energy forward to the mower’s input driveline.<\/p>\n At the tractor end, a splined PTO shaft yoke slides over the tractor’s PTO output and is secured with a locking mechanism. This yoke connects to the first PTO shaft universal joint, which allows the shaft to operate at an angle relative to the tractor’s centerline. The universal joint is a cross-and-bearing assembly that permits rotational motion to be transmitted through a changing angle as the tractor and mower move independently over uneven terrain.<\/p>\n The center section of the shaft consists of telescoping PTO shaft tubing with a profiled cross section (typically lemon or star shaped). As the tractor turns or the mower wings fold, the distance between the tractor PTO and the mower input changes. The telescoping tubes slide in and out to accommodate this change in length while continuing to transmit full torque. This is critical for batwing mower applications because the three-section cutting deck creates significant geometry changes during turns and transport.<\/p>\n At the implement end, a second PTO shaft u joint connects the shaft to the mower’s gearbox input. In the case of this Woods batwing mower PTO shaft, the implement end features a constant velocity (CV) joint instead of a standard U-joint. The CV joint maintains a uniform output speed regardless of operating angle, eliminating the twice-per-revolution speed fluctuation inherent in single U-joint designs. This is particularly important for batwing mowers, where the three gearbox units on the center and wing decks require smooth, vibration-free input to avoid premature gear wear.<\/p>\n During operation, the tractor PTO spins at either 540 RPM or 1000 RPM depending on the tractor configuration. This rotational speed is carried through the shaft assembly at full torque to the mower gearbox, which then distributes power to the cutting blades via internal bevel gears. Overload protection can be integrated through a PTO shaft shear bolt or slip clutch PTO shaft mechanism, which will disengage or break under excessive load to protect both the shaft and the gearbox from damage caused by striking solid objects like rocks, stumps, or buried debris.<\/p>\n

\nUnlike standard cross-joint PTO drive shafts, this shaft features a constant velocity (CV) joint that maintains a uniform rotational speed throughout the full range of operating angles. This eliminates the pulsation and vibration commonly found in conventional PTO driveline shaft assemblies, reducing stress on the mower gearbox and extending the service life of all connected drivetrain components during extended field operations.<\/p>\n
\nAvailable in Cat 4 (60 HP @ 540 RPM \/ 110 HP @ 1000 RPM), Cat 5 (90 HP @ 540 RPM \/ 170 HP @ 1000 RPM), and Cat 6 (110 HP @ 540 RPM \/ 184 HP @ 1000 RPM) ratings. This range of PTO shaft sizes ensures you can match the shaft to your tractor’s horsepower output and the specific demands of your batwing mower, whether running at 540 or 1000 rpm PTO shaft speed.<\/p>\n
\nEvery PTO shaft cover is included as a standard feature, not a paid add-on. The full-length safety shield rotates freely around the shaft during operation, protecting operators from the spinning driveline. The guard meets CE safety requirements and is constructed from impact-resistant material that will not crack or degrade under UV exposure, even after years of outdoor use in agricultural environments.<\/p>\n
\nEngineered as a bolt-on replacement of Weasler PTO shaft and replacement of Woods PTO shaft assemblies. No shimming, no PTO shaft adapter required, and no modifications to the mower input shaft or the tractor PTO output. The PTO shaft yoke dimensions, spline profiles, and overall shaft length are matched to the OEM specification so the shaft slides straight on and locks into position.<\/p>\n
\nThe telescoping PTO shaft tube sections are manufactured from high-strength alloy steel with a precision-machined profile. This heavy duty PTO shaft tubing delivers superior torque capacity and resists deformation under peak loads. The lemon-profile or star-profile cross section provides a positive, low-backlash fit between the inner and outer tubes, ensuring smooth telescoping action and consistent power delivery across the full stroke range.<\/p>\n
\nThis tractor PTO drive shaft is offered with three different tractor-side spline profiles: 1.375″-6 spline, 1.375″-21 spline, and 1.750″-20 spline. This covers the vast majority of North American, European, and Asian utility and row crop tractors used with batwing mowers, allowing you to order a single custom PTO shaft that matches your exact tractor without aftermarket spline adapters.<\/p>\n
<\/p>\nTractor PTO Shaft Parts<\/h2>\n

\nThe tractor-side PTO shaft yoke is the forged steel coupling that slides onto the tractor’s PTO output spline. It features a spring-loaded locking collar that snaps into the detent groove on the PTO stub, providing a secure connection that can be released quickly for disconnection. The yoke bore is precision-broached to match one of three spline profiles (1.375″-6, 1.375″-21, or 1.750″-20).<\/li>\n
\nEach PTO shaft universal joint consists of a precision-machined cross with four needle bearing caps. These bearings allow the shaft to transmit torque through an angular offset between the tractor and the implement. High-quality needle bearings with grease-sealed caps ensure long service life. Each PTO shaft u joint should be re-greased at regular intervals to maintain performance and prevent premature failure.<\/li>\n
\nLocated at the implement end, the CV joint is the defining feature of this PTO driveline shaft. Unlike a standard U-joint that produces speed variation at operating angles, the CV joint delivers a constant output speed. This is achieved through a double-cardan or ball-type mechanism that cancels out the inherent velocity fluctuation. This reduces gearbox wear and provides smoother cutting performance in your Woods batwing mower.<\/li>\n
\nThe inner and outer PTO shaft tube sections are manufactured from precision-drawn alloy steel with a lemon or star cross-section profile. This profiled PTO shaft tubing prevents relative rotation between the tubes while allowing smooth axial sliding. The tubes accommodate changes in distance between the tractor PTO and the mower input during turns, terrain changes, and three-point hitch adjustments.<\/li>\n
\nThe PTO shaft cover consists of two telescoping plastic guard tubes with bearing-mounted end caps, plus restraining chains that attach to the tractor and implement. The shield is designed to remain stationary while the shaft spins inside it, protecting the operator from contact with the rotating driveline. Replacement shields and chains are available as PTO shaft parts and should be replaced immediately if cracked, missing, or not rotating freely.<\/li>\n
\nDepending on your configuration, this shaft can include a shear bolt PTO shaft or a PTO shaft with slip clutch mechanism. The PTO shaft shear bolt is a sacrificial fastener that breaks under a predetermined torque load, disconnecting the driveline to protect the gearbox. The slip clutch PTO shaft option uses a spring-loaded friction plate assembly that allows the shaft to slip momentarily under overload and then re-engage automatically.<\/li>\n<\/ul>\n
