If you’ve ever had a pulley slip on a shaft or a gear come loose when you’re in the middle of harvest, you know how important that little half-moon key is. This 1/4 inch by 1 inch woodruff key is the simple piece that keeps pulleys, gears, and other rotating parts locked in their proper position on shafts throughout your tractor.
What You’re Getting
- Precision-cut woodruff key that fits snugly in keyway slots

- Hardened steel construction that won’t shear under normal loads
- Half-moon shape distributes stress evenly across the shaft
- Direct replacement for worn or missing keys in various systems
Built for Real Farm Work
This key fits a wide range of tractor systems where 1/4 inch woodruff keys are specified. You’ll find this size used in hydraulic pump drives, PTO assemblies, engine accessories, and transmission components across many tractor brands. It’s the kind of small but critical part that keeps power flowing where it needs to go.
Made to Last
Farm equipment puts serious stress on drive components, and a weak key can mean expensive downtime. This woodruff key is made from quality steel that’s heat-treated to handle the shock loads and vibration that come with heavy field work. The precision manufacturing ensures it fits tight in the keyway without binding.
Good to Know
Installation is straightforward – just slide the key into the shaft’s keyway slot before installing your pulley or gear. The half-moon shape self-centers and the flat side sits flush with the shaft. Keep a few spares in your toolbox because these small keys have a way of disappearing when you need them most.
