Operating Tips
•
Clean the area of trash, branches, and rocks
before operating to prevent equipment damage.
•
Always use full throttle (maximum engine speed)
when grinding.
•
Cut the edges of the stump for more efficient
grinding. Once your cutting swath is close to 1/4
of the wheel diameter, lower the grinder and begin
cutting on the edge again.

•
Listen to the engine and watch the grinder wheel
speed to maintain the speed of the wheel. Slow
down the head sweep by feathering the joystick as
cutting becomes difficult.
•
As you grind from left to right, most of the debris
goes to the left of the grinder wheel. When you
grind from the right to left, the debris goes to the
right.
•
You may also grind a stump from the side to lessen
turf damage.
