When you’re dealing with rotary cutter blades, the last thing you want is a loose bolt letting your blade come free in the middle of a cutting job. This jam nut does exactly what its name suggests—it jams tight against the main nut to lock everything in place, so your blades stay put when you’re working through thick brush or rough pasture.
What You’re Getting
- 1″-14 thread pitch that matches standard rotary cutter blade bolt systems
- Jam nut design that locks against the primary nut for extra security
- Heat-treated steel construction that won’t strip or crack under pressure
- Low profile that won’t catch on debris or interfere with blade rotation
Built for Real Farm Work
This jam nut fits a wide range of rotary cutters including BD90, GB50, GB108, PG210, SX50, SX60, 5X5, and 6X6 models. These are the workhorses you see cutting roadside ditches, clearing fence rows, and maintaining pastures—jobs where blade security isn’t just important, it’s critical for safety.
Made to Last
Rotary cutter hardware takes serious abuse from rocks, stumps, and the constant vibration of spinning blades. This jam nut is built to handle those conditions without loosening up or wearing out. The steel holds its threads and the finish resists rust, even when you’re working in wet conditions.
Good to Know
Always use this jam nut with the proper blade bolt—never try to substitute or skip it. Thread it on after your main nut and snug it down tight against the primary nut. A quick check of your blade bolts and jam nuts before each cutting season can save you from losing a blade when you need your cutter most.
