If you’ve ever been in the middle of hooking up your big disc harrow or heavy cultivator and had a worn link pin snap or work loose, you know how frustrating it can be. This Category 3 link pin is what connects your tractor’s lower lift arms to those heavy implements, handling all the stress when you’re lifting, lowering, or working in tough ground conditions.
What You’re Getting
- Category 3 sizing with 37mm diameter handles the forces from big implements and powerful tractors
- 175mm length provides the right fit for standard Cat 3 three-point hitch geometry
- Zinc plating resists corrosion from moisture, fertilizer, and chemical exposure
- Hardened steel construction won’t bend or break under normal field loads
- Direct replacement—slides right into your existing lift arm bushings
Built for Real Farm Work
This pin is designed for Category 3 three-point hitches found on larger tractors typically running heavy implements like big discs, cultivators, planters, and tillage equipment. Whether you’re working a 12-foot disc behind a 150HP tractor or hooking up a heavy-duty cultivator for spring field prep, this pin provides the secure connection between your tractor’s hydraulic lift system and your implements.
Made to Last
Farm work puts tremendous stress on hitch pins—they see shear loads when lifting implements, side forces during turns, and constant vibration from field operations. The zinc plating helps the pin resist rust and corrosion from exposure to moisture and chemicals, while the proper metallurgy ensures it won’t fail when you need it most.
Installation Notes
This is a straight replacement for worn or damaged Category 3 link pins. Make sure your implement is properly supported before removing the old pin, and keep some penetrating oil handy if the old pin is stuck. The 175mm length is standard for most Cat 3 applications, but double-check your setup to be sure.
