This automation style lock nut keeps everything secure while your cutter powers through thick brush and tall grass.
What You’re Getting
- 1″-14 thread pitch fits standard rotary cutter blade bolts perfectly
- Automation style design provides superior holding power compared to regular nuts
- Built to handle the constant vibration and impact of rotary cutting
- Direct replacement that threads on just like your original
Built for Real Farm Work
This lock nut works with a wide range of rotary cutters from John Deere and Servis Rhino models. Whether you’re bush-hogging pastures, cutting roadside ditches, or clearing fence rows, it keeps your blade assembly tight and working properly throughout the job.
Made to Last
Rotary cutters put tremendous stress on blade hardware with all the spinning, bouncing, and hitting obstacles. This nut is engineered to grip tight and stay put, even when your cutter is working overtime through tough conditions season after season.
Good to Know
Always use a torque wrench when installing blade hardware—over-tightening can damage threads while under-tightening creates safety hazards. Check blade bolt tightness regularly, especially when working in rocky conditions or cutting heavy brush.
