Description

When your disc mower blades start wobbling or you notice loose hardware during your pre-season inspection, it’s time for new mounting bolts. These essential fasteners take a beating from rocks, stumps, and the constant vibration of cutting through tough hay crops. A loose or worn bolt can cost you blade time and create dangerous flying metal—problems you definitely don’t need when the weather window’s closing fast.

What You’re Getting

Heavy-duty 12mm bolt designed specifically for disc mower blade mounting
Precise threading that won’t strip out during installation or removal
Durable construction that handles the shock loads from hitting obstacles
Box of 25 bolts—enough for multiple blade changes or to keep spares on hand

Built for Real Farm Work

These bolts are engineered for the demanding world of disc mower operation, whether you’re cutting first-crop alfalfa in rocky ground or cleaning up weedy fence rows. The 12mm size provides the strength needed to keep blades secure while allowing for proper blade rotation when you hit something solid. They’re designed to hold tight through thousands of acres of cutting.

Made to Last

Farm equipment hardware needs to be tough, and these bolts deliver. They’re built to withstand the constant vibration, impact loads, and weather exposure that comes with mowing operations. The quality steel construction and proper heat treatment mean they’ll keep your blades where they belong season after season.

Good to Know

Always replace blade bolts when installing new blades—reusing stretched or worn hardware is asking for trouble. Check bolt torque after the first few hours of operation, as new bolts often need retightening. Keep a few spares in your toolbox since field repairs sometimes mean removing bent bolts that can’t be reused.
