8.3 Rotate Cutting Teeth

Check cutting teeth every 4 hours of use. Keep cutting teeth in 

good condition. Unit will cut faster and remaining teeth will last 

longer if broken or worn teeth are replaced. 

Each tooth can be rotated up to two times from its original 

position before replacement is necessary.

1.  Park stump grinder on a level surface.
2.  Lower rotor to the ground.
3.  Shut off engine and lockout engine controls.
4.  Inspect teeth for wear on top edge. Once top edge is 

worn, rotate tooth so a new edge is on top (cutting) edge.
