5. Setting & Sharpening Teeth
Among the most critical elements of the stump grinder is the cutting wheel. It is also the most
subject to damage and wear. In the course of grinding stumps it not only makes contact with the
wood, but also encounters numerous abrasives and objects in the stump's environment, such as dirt,
stones, large rocks and buried scrap.
The loss and wear of cutting teeth can significantly impair the efficiency and performance of the
stump grinder. Therefore, it is important to make frequent inspections of the condition of all the
cutting teeth and to sharpen or replace any damaged or worn teeth. Sharpening the teeth before
excessive wear will result in longer lasting teeth and better performance.
Setting Teeth
Installing pockets
1.
Locate the straight teeth and pockets on your wheel.
2.
Remove one set of straight teeth and pockets.
3.
Clean this area with a wire brush.
4.
Start with a counterbored pocket. Counterbored pockets have non-threaded big
holes. They go on the right-hand side of the wheel as you face the wheel. Install
two pocket bolts into the counterbored pocket holes.
5.
Apply anti-seize onto the threaded position of the pocket bolt.
6.
Slide the counterbored pocket and pocket bolts through the holes in the wheel
from the right side and thread them into the threaded holes in the threaded
pocket. Firm up the pocket bolts until pockets are firm on the wheel. Do not
tighten then down yet.
