Page 17: Equipment Operation
EQUIPMENT OPERATION WARNING! To avoid death or serious injury, do not grind stumps containing embedded foreign objects such as nails, wire, metal fragments, etc. Wear heavy-duty work gloves, ANSI-approved goggles behind a full face shield, steel-toed work boots, and a dust mask. Securely attach the stump grinder to the tractor’s 3-point hitch system and install the PTO shaft. - Page 18 Remove the leg locking pins (#37), slide the legs (#13) up inside the tubes of the back frame (#15), and reinstall the locking pins (#37) to secure them in place. Reverse over a tree stump and lower the stump grinder so it will remove 2" (50 mm) per pass.
- Page 19 Once the stump is at ground level, continue to take up to 2” (50 mm) deep passes until the stump and roots are 4-6” (100-150 mm) below grade. Keep a watch out for foreign objects below the soil like rocks or buried metal. These can damage or break the teeth resulting in poor grinding performance.

Page 20: Stump Grinding Procedure
STUMP GRINDING PROCEDURE The flywheel spins in a clockwise manner (when facing the rear of the machine) with the effective cutting area in the lower-left quadrant as shown below: Effective cutting area Therefore, when grinding a tree stump, always start from the right side of the stump, moving incrementally to the left, pulling the grinder straight forward through the stump on each pass. -
Page 21: Incorrect Grinding Procedures
INCORRECT GRINDING PROCEDURES It is critical that the stump grinder is never pulled through the center of a stump or ground from left-to-right. This will induce severe vibration and cause the grinder to sway and bounce. It may also damage the machine and/or break teeth. Follow the directions on the previous page to ensure efficient and safe grinding. -
