SCITOO Yellow 27.5″-40.55″ PTO Shaft
Features: Adjustable length with compressed 27.5 in (700 mm), recommended 31.5 in (810 mm), extended 40.55 in (1030 mm). Supports two speeds at 540 rpm and 1000 rpm. End fittings are 1-3/8″ x 6 splines on both tractor and implement ends. Crafted from 20CrMnTi carburized steel, with a Q345 steel tube inside the shield for durability.
Best for: Small to mid-size tractors using side-mount or compact bush hogs where space is tight and a flexible PTO reach is needed. This shaft suits machines requiring robust telescoping action and reliable spline engagement.
Caution: With telescoping components, keep the shaft shield clear of debris to avoid binding. Confirm exact spline size and length before ordering to avoid misfit.
SCITOO Yellow 37″-59″ PTO Shaft
Features: Compressed 37 in (950 mm), recommended 44.5 in (1135 mm), extended 59 in (1500 mm). Engineered for up to 55 Hp (40 Kw) at 1000 rpm, suitable for higher torque side-mount mowers. Ends are 1-3/8″ x 6 splines with solid universal joints and a durable shield.
Best for: Mowers requiring greater reach and higher torque capacity, especially mid-to-large tractors with side-mounted implements. It offers a balance between length and strength.
Caution: Ensure the extended length does not exceed safe operating clearance between tractor and implement to prevent shaft binding during turns.
SCITOO Yellow 43″-71″ PTO Shaft
Features: Compressed 43 in (1100 mm); extended 71 in (1820 mm). Supports two-speed operation at 540 rpm and 1000 rpm, with 1-3/8″ x 6 spline ends on tractor side and a round end on the implement side. Built with a 20CrMnTi universal joint system and a Q345 steel tube inside the shield.
Best for: Heavy-duty side-mounted bush hogs where a long reach and strong torque are needed, particularly on larger tractors or when mowing around larger fields.
Limitation: Longer shafts require careful alignment and more space to operate safely; verify available clearance before installation.
Bush Hog 10″ Solid Molded Finish Mower Wheel Assembly
Features: 10″ solid molded wheel with 1″ yoke shaft diameter and 9 1/4″ yoke shaft length; includes spacers for proper fit (4 x 1″ spacers, 2 x 1/2″ spacers).
Best for: Replacing worn mower wheels to maintain stable cutting height and ground clearance on Bush Hog equipment. Useful for ongoing maintenance of side-mount mowers requiring reliable wheel components.
Limitation: Spacer and bolt compatibility vary by model; confirm exact wheel and yoke dimensions for your machine before purchase.
63813BH Replacement Tail Wheel Hub
Features: 4-bolt hub with 1″ bushings, 5″ axle tube (WOA: 5 1/4″), 4 – 1/2″ studs, lock washers and nuts on a 5″ circle, and a 3 1/2″ pilot hole. Zerk fitting included for lubrication access.
Best for: Replacing tail wheel hubs on Bush Hog models to maintain smooth trailer-like turning and mowing stability. Suitable for common Bush Hog side-mount attachments that rely on tail wheel pivots.
Caution: Verify the hub fits your exact Bush Hog model to avoid misalignment or improper rotation.
Buying Guide: Key Considerations For Side Bush Hog Setups
- Compatibility: Check spline size, shaft ends, and overall length to ensure a proper fit with your tractor and implement.
- Length and reach: Choose PTO shafts with compressed, recommended, and extended lengths that match your mowing geometry and clearance.
- Torque and horsepower: Match shaft torque ratings to your mower’s engine power to prevent joint wear or torsional failures.
- Durability: Look for carburized steel universal joints and reinforced tubes for long-term use in rough field conditions.
- Maintenance: Consider parts with easily replaceable components, such as wheels, tail hubs, and standard spacers for quick servicing.
- Safety: Ensure shields are intact and the shaft is properly guarded to prevent debris launch and injury during operation.
Frequently Asked Questions
- What is a PTO shaft and why is it important for side bush hogs?
– A PTO shaft transmits power from the tractor to the mower. For side-mounted configurations, a telescoping shaft accommodates varying distances and angles, ensuring efficient operation and safety. - How do I determine the correct PTO shaft length?
– Measure the distance between the tractor PTO yoke and the implement yoke in the operating position, then select a shaft with compressed, recommended, and extended lengths within that range. - Are longer PTO shafts always better?
– Not necessarily. Longer shafts can offer more reach but require adequate clearance and safe operation space to avoid bending or hitting obstacles. - Can replacement wheels affect mowing performance?
– Yes. Proper wheel height and alignment maintain cutting height and stability, reducing wear on blades and improving cut quality. - What maintenance steps help extend PTO shaft life?
– Regularly inspect universal joints, keep shields intact, lubricate as recommended, and replace worn components promptly to prevent failure.
