Description
When your PTO starts slipping or chattering during heavy implement work, the culprit is often a worn fiber disc inside the clutch pack. This friction material takes the heat and abuse of constant engagement and disengagement, especially during demanding jobs like running balers, mowers, or post hole diggers. When it wears out, you’ll notice the PTO not grabbing like it should or that burning smell that means it’s time for a replacement.
What You’re Getting
- 5-1/4 inch outer diameter with 4 inch inner diameter for precise fit in your PTO clutch assembly
- 51-spline design ensures proper engagement with your tractor’s PTO system
- High-quality fiber material engineered to handle the heat and friction of PTO operation
- Individual replacement disc lets you service just the worn component when the metal disc is still good
Built for Real Farm Work
This fiber disc works in the same applications as complete clutch disc kits, giving you the flexibility to replace just the worn friction material when the rest of the clutch components are still serviceable. It’s designed for tractors running PTO-driven equipment where smooth, reliable power transfer is critical for getting work done efficiently.
Made to Last
The fiber material is formulated specifically for agricultural PTO applications, resisting the glazing and premature wear that can happen with inferior friction materials. It maintains consistent grip characteristics even under the varying loads and temperatures that come with real farm work.
Good to Know
This is the replacement fiber disc only – you’ll need to inspect your metal disc and other clutch components to determine if they need replacing too. If you’re doing a complete overhaul, consider the full clutch disc kits for a comprehensive repair. Installation requires splitting the tractor to access the PTO clutch assembly, so plan for proper shop time and equipment.
