Description
If you’ve ever had a PTO shaft slip or a hydraulic pump fail right when you’re in the middle of field work, you know how critical these small parts can be. This woodruff key might look simple, but it’s the piece that keeps your shaft and pulley locked together under the stress of heavy farm work. When it wears out or shears, you’re dead in the water until you get a replacement.
What You’re Getting
- Precise 5/16 inch width by 1-1/4 inch length sizing for proper fit in keyway slots
- Hardened steel construction that handles the shock loads of PTO engagement and disengagement
- Semi-circular design distributes stress evenly to prevent premature failure
- Direct replacement for worn or damaged keys without machining or modifications
Built for Real Farm Work
This key works in a wide range of tractor PTO shafts, hydraulic pump drives, and implement couplings across all major brands. Whether you’re connecting a rotary cutter, round baler, or hydraulic pump to your tractor’s power, this key ensures the connection stays solid when the going gets tough.
Made to Last
Farm equipment puts tremendous stress on drive components, especially during startup and under load. This woodruff key is made from quality steel that’s tough enough to handle the torque but designed to fail before more expensive components get damaged. It’s cheap insurance for your expensive machinery.
Good to Know
Always check the keyway for wear or damage before installing a new key. A quick file job on rough edges helps ensure proper fit. Keep a spare or two in your toolbox – when these fail, they usually take you by surprise at the worst possible time.
