Description
When you hit a rock or piece of debris while mowing, you don’t want to damage expensive gearbox parts or bend the mower shaft. That’s where this shear bolt comes in—it’s designed to break on impact, protecting the costly components behind it. Think of it as a sacrificial part that saves you from much bigger repair bills.
What You’re Getting
- Zinc and yellow coating resists rust and corrosion, even in wet conditions
- M10 x 65mm coarse thread for secure fit in topper and rotary cutter applications
- Engineered to shear at the right force—not too weak, not too strong
- Quality steel construction that holds up to normal mowing forces but breaks when it should
Built for Real Farm Work
This shear bolt is commonly used in major topper mowers and rotary cutters where protection of the drive system is critical. Whether you’re bush-hogging pastures, cleaning up fence lines, or maintaining roadsides, this bolt gives you peace of mind knowing your equipment is protected from sudden impacts.
Made to Last
The zinc and yellow coating isn’t just for looks—it provides excellent corrosion resistance so the bolt won’t seize in place when you need it to do its job. The steel is heat-treated to precise specifications so it shears cleanly when overloaded.
Good to Know
Always keep a few spare shear bolts in your toolbox because you’ll need them eventually. When installing, don’t overtighten—just snug them up. The bolt needs to be able to shear properly, and overtightening can actually make them harder to break when they need to.
