Description
When your implement hits a rock, binds up, or suddenly overloads, something’s got to give—and you’d rather it be a replaceable clutch part than your expensive gearbox or PTO shaft. This radial pin clutch acts as a mechanical fuse in your driveline, using spring-loaded pins that disengage when torque exceeds safe limits. It’s like having an insurance policy built right into your PTO system that protects both your tractor and implement from costly damage.
What You’re Getting
- 1-3/8″ 6-spline connection fits standard tractor PTO shafts perfectly
- Spring-loaded radial pins provide reliable overload protection without electronics
- Adjustable torque setting lets you dial in protection for different implements
- Quick reset design gets you back to work without tools or disassembly
- Built tough to handle repeated engagement cycles and temperature swings
Built for Real Farm Work
This clutch protects valuable PTO-driven equipment like rotary cutters, balers, spreaders, and tillers from sudden shock loads. The 1-3/8″ 6-spline design matches the standard PTO connection found on most mid-size to large tractors, making it a universal fit for protecting your investment in implements.
Made to Last
Weasler doesn’t cut corners on PTO components because they know what happens when driveline parts fail. The pins and springs are built to handle repeated engagement cycles, temperature swings, and the constant stress of transferring power through changing angles while resisting wear and fatigue.
Good to Know
You’ll need to split the clutch housing if you ever need to service the internal components, so plan on having the right tools and workspace. Clean everything thoroughly during assembly and check that all pins move freely before putting it back together. A light coating of grease on the pin contact points helps with smooth operation, but don’t overdo it or debris will stick and cause problems.
