G. Screw the slotted nut back on the threads of the gear-
box output shaft to keep from losing the nut and to
protect the threads on the shaft.
H. Remove the two bolts holding the PTO clutch assem-
bly on the gearbox input shaft. Slide the PTO clutch
assembly off the input shaft.
I. Remove bolts and locknuts securing gearbox to
frame. Remove gearbox.
DO NOT HAVE ANYONE HOLD THE WHEEL WHEN
HITTING THE END OF THE PULLER SCREW WITH A
HAMMER. The wheel may jump off the shaft and
could cause injury!
ROTATING CUTTING TEETH
——————————————————
The cutting teeth on the outer edge and side of the cut-
ting wheel do the majority of the work.
It is recommended that when these teeth become dull,
that you exchange them with teeth that are located further
towards the center of the wheel. This will spread the wear
among the teeth and keep the “sharper” teeth in the main
cutting area of the wheel.
The number of stumps that can be ground before
replacing teeth depends on several factors:
a. Any foreign objects contacted?
b. Abrasive soil conditions.
c. How deep stumps are cut below ground?
d. How large are the stumps?
e. How dry is the soil? (Dry, hard soil will cause more
wear than moist soil.)
CUTTING WHEEL & GEARBOX
REMOVAL
——————————————————
A. Raise stump grinder using both the hydraulic lift
cylinder and the 3 pt. hitch. Follow normal shutdown
procedure before dismounting from the power unit.
B. Lower the jack stand and pin securely.
C. Lower the tractor 3 pt. hitch first and then the hydraulic
lift cylinder so the stump grinder is on the ground or
shop floor. This will position the bottom of the wheel
just slightly above ground or floor level.
D. Remove the side shield from the cutter wheel housing.
E. Remove the cotter pin and slotted nut. (Use a large
block of wood against the edge of the cutting wheel to
break the slotted nut loose.)
F. Use a good three (3) arm wheel puller to pull the cut-
ting wheel off the tapered splined output shaft of the
gearbox.
NOTE: Once you have tension on the wheel with the
wheel puller, a sharp rap with a hammer will “pop” the
wheel off.

INSTALLATION
——————————————————
A. Raise stump grinder using both the hydraulic lift
cylinder and the 3 pt. hitch. Follow normal shutdown
procedure before dismounting from the power unit.
B. Lower the jack stand and pin securely.
C. Lower the tractor 3 pt. hitch first and then the hydraulic
lift cylinder so the stump grinder is on the ground or
shop floor. This will position the bottom of the wheel
just slightly above ground or floor level.
D. Attach gearbox to frame using bolts and nuts.
E. Install cutting wheel onto gearbox securing with
castellated nut and flat washer. Torque nut to 350
ft./lbs. Wear heavy work gloves to protect hands from
sharp edges.
F. Install cotter pin to retain nut. It may be necessary to
slightly loosen nut to install cotter pin.
G. Slide PTO clutch assembly on the the gearbox input
shaft. Install the two bolts and tighten.
NOTE: The two bolts need to align with the groove in
the gearbox input shaft. It may require moving the
PTO clutch assembly forward or back to get proper
alignment.
H. Fill gearbox with oil to proper level.
I. Replace the side shield on the cutter wheel housing.
Tighten these nuts securely.
