OPERATING TECHNIQUE
1. Power for operating the stump grinder is supplied
by the tractor PTO. Know how to stop the tractor
and stump grinder quickly in an emergency.
2. Position stump grinder above stump to be
removed. Engage PTO at low engine rpm to
minimize stress on the drive system and gearbox.
With PTO engaged, increase PTO speed to 540
rpm and maintain throughout grinding operation.
3. Lower tractor 3-point arm until pads on stump
grinder are firmly on the ground.
4. Activate top cylinder to lower the cutting wheel onto
the stump to desired depth.
NOTE: The amount of material removed may vary
depending on tractor size and hardness of wood.
5. Start cutting wheel on left edge of stump and slowly
activate side cylinder to begin grinding. Cutting
wheel can pivot 55-degrees from side to side.
6. With pass across stump completed, activate side
cylinder to the left, lower top cylinder to remove
more material, and activate side cylinder to the
right. Continue this process until stump is removed.
NOTE: If stump is too large to remove in one pass,
reposition tractor and start operating procedures over.
NOTICE
■ Top cylinder must be completely raised to
avoid driveline damage before raising 3-point lower
lift arms.
When finished grinding stump, disengage PTO, raise
top cylinder, and raise stump grinder off the ground
with the 3-point lower lift arms.
