Description

When you’re cutting hay on a tight schedule, the last thing you need is to lose time dealing with worn-out or broken blade bolts. These high-stress fasteners take a beating from rocks, stumps, and the constant spinning action of your disc mower, and when they fail, your whole operation comes to a halt. This replacement bolt keeps your cutting discs secure and your mowing smooth.

What You’re Getting

Heavy-duty construction designed to handle the vibration and impact of disc mowing
Precision threading that won’t strip or work loose under field conditions
Direct OEM replacement quality that matches original factory specifications
Easy installation with standard tools—no special equipment needed

Built for Real Farm Work

This bolt fits a wide range of John Deere disc mower conditioners from compact utility models like the 525 and 530 up through the big self-propelled units like the 956. Whether you’re cutting first crop alfalfa or cleaning up fence rows, these machines see hard use in tough conditions, and their blade bolts need to be up to the task.

Made to Last

Disc mower blades spin at high RPM and deal with everything from green grass to dried stalks and the occasional rock. The bolt has to hold that blade securely while absorbing shock and resisting the constant stress of rotation. This replacement uses quality steel with proper heat treatment to stand up to the punishment.

Installation Notes

Always replace blade bolts with the cutting disc removed from the mower to work safely. Check the blade and disc for damage while you’ve got everything apart, and don’t forget to torque the new bolt to spec. A little thread locker on the threads helps prevent loosening from vibration.
