The EXR-4800 Excavator Brush Cutter Blade Bolt sees wear and tear in the day to day use. We recommend that when your blades need to be replaced on your EXR-4800 that you inspect your bolt, nut and roll pin. If you have any questions let us know we are happy to help!
We recommend ordering the Blade Bolt replacement kit as well. The rotary brush cutter blades do see wear and tear and as a safety precaution we recommend replacing both blade and blade bolts on your rotary brush cutter.
