Note: All models listed use a standard 1-3/8″ diameter with 6-spline ends to fit most brush hogs, finish mowers, and rotary cutters. The lengths are adjustable via telescoping tubes, and many include slip clutch options for overload protection. When selecting a shaft, consider your tractor’s PTO RPM, horsepower range, and the maximum extended length required by your implement.
VEVOR PTO Shaft, 43″-57″ Series 5
Durability and precision are central to this model. Built with a slip clutch and a solid 20CrMnTi carburized steel universal joint, it integrates a Q345 steel inner tube for added strength. It features both ends at 1-3/8″ x 6 Spline, aligning with common tractors and implements. The telescoping design supports a compressed length of 43″ and an extended length of 57″, enabling flexible fit for various mowing setups. Torque ratings at 540 rpm and 1000 rpm ensure dependable performance for typical brush hog use.
VEVOR PTO Shaft, 43″-61″ Series 4
This Series 4 shaft offers a 1-3/8″ 6-spline tractor end and a round implement end, making it versatile for different brands of mowers and tillers. The telescoping tube design extends from 43″ to 61″ to handle longer linkages between tractor and implement. It is CE certified and uses a solid 20CrMnTi joint coupled with a Q345 inner tube, delivering robust strength for demanding field conditions. Torque figures at 540 rpm and 1000 rpm indicate solid performance for most rotary cutters and finish mowers.
VEVOR PTO Shaft, 39″-55″ Series 4
The 39″ to 55″ model uses a six-spline tractor end paired with a round implement end to fit common equipment. It features a 20CrMnTi universal joint and a Q345 steel tube, enclosing a robust shield. The telescoping design allows for adjustable length, while the torque specs at 540 rpm and 1000 rpm provide broad compatibility with typical brush hogs and rotary cutters. This shaft strikes a balance between compact size and range, ideal for mid-sized mowing tasks.
VEVOR PTO Shaft, 31.5″-41″ Series 4
This compact shaft is designed for smaller tractors and implements, extending from 31.5″ to 41″. It uses a 6-spline end at both tractor and implement sides, with a slip clutch option available. The tube is a Q345 steel inner with a solid 20CrMnTi universal joint, and CE certification signals reliable build quality. Its shorter length reduces overhang and vibration on compact equipment, while still delivering the necessary power to finish mowers or rotary cutters in tighter spaces.
DEXSO 43″-57″ Series 5
DEXSO offers a durable 43″ to 57″ PTO shaft featuring a slip clutch option and a robust 20CrMnTi universal joint with a Q345 steel inner tube. It uses 1-3/8″ x 6-spline ends on both tractor and implement sides for broad compatibility. The telescoping design supports flexible mounting distances, and torque figures at 540 rpm and 1000 rpm indicate the shaft can handle common mowing workloads without excessive stress. CE certification further supports reliability in agricultural settings.
Buying Guide: Key Purchase Considerations
- Length range and adjustability: Ensure the shaft can extend to accommodate your tractor-implement distance without binding. Look for telescoping tubes that accommodate the longest possible operating length.
- Ends and compatibility: Most brush hogs and finish mowers use 1-3/8″ x 6-spline ends. Some models include round ends or friction discs; verify your implement’s input yoke and PTO coupling.
- Slip clutch vs. no clutch: A slip clutch provides overload protection, reducing gear and shaft damage during heavy loads or sudden jams. If you frequently cut heavy brush, a slip clutch is advantageous.
- Materials and certification: CE-certified shafts with 20CrMnTi universal joints and Q345 tubes offer durable performance in harsh field conditions. Look for robust shielding and solid joints to minimize wear and vibration.
- PTO RPM performance: Check torque ratings at standard PTO speeds (540 rpm and 1000 rpm). This helps ensure the shaft can handle your mower’s horsepower range without overheating or snapping.
- Maintenance considerations: Choose shafts with simple, accessible joints and shields. Regular inspection of universal joints and lubrications helps prolong life in dusty, debris-filled environments.
- Warranty and supplier support: Purchase from reputable brands that offer support and return policies, ensuring you can obtain replacements or parts if needed.
For most mid-to-large mowing setups, a 43″ to 57″ range with 6-spline ends and a slip clutch provides a versatile, durable option across a variety of brush hogs and finish mowers. Always confirm your tractor’s PTO output and implement input before purchase to ensure a precise fit and reliable operation in field conditions.
