Stump Removal Procedure
1: Prepare the machine at the stump:
• Drive the machine into position with the cutting wheel
near the top edge of the stump.
• Move the engine throttle to IDLE.
• Start cutting wheel rotation
• Increase the engine to increase the cutter wheel.
2: Remove the roots:
• Swing the cutting wheel to one side, then lower it into
the nearside roots that may be buried at the foot of the
stump, and swing the cutting wheel across them until
they are sufficiently removed
3: Cutting the stump properly:
• Raise the cutting wheel to the top of the stump and
advance the machine to a combined position where
the center of the shaft remains just above the top of
the stump, such that upon swinging the cutting wheel,
a bite approximately 4” deep may be taken.
• Sweep the cutting wheel across the stump, taking an
approximately 2.75” deep bite.
• After the first bite is taken, lower the cutting wheel about
2” while is off to the side and swing the cutting wheel
across for another bite.
• Continue repeating this procedure until all of the amount
of stump in the path of the downward swing of the
cutting wheel is gone.
4: Cut another level of the stump:
• Raise the cutting wheel above the stump once again,
and starting with the cutting wheel swung to one side,
advance the machine slightly (about 2”) and repeat
STEP 3.
Repeat STEP 4 consecutively
5: Cut Remaining Roots:
• Cut the remaining roots as described in STEP 1 until
the entire stump is satisfactorily removed.
• After the stump has been fully removed, stop the cutting
wheel rotation. Raise and center the cutting wheel.
• Machine is ready for travel to the next destination
6: Once the Stump is completely cut:
• Reduce the throttle to IDLE and shut off the cutting
wheel rotation.
• Stop the cutting wheel rotation quickly by gently lowering
the cutting wheel into the soil.
• Fully raise and center the cutting wheel. The machine may
then be self-propelled to the next destination
