Removal (Fig. 7)
1. Park machine on a level surface, lower cutting deck,
stop engine, engage parking brake and remove key
from the ignition switch.
2. Drain oil from planetary wheel drive/brake assembly.
CAUTION
When removing front wheel, use correct jacks
and supports. Make sure machine is parked on a
solid, level surface such as a concrete floor.
Prior to raising machine, remove any attach-
ments that may interfere with the safe and prop-
er raising of the machine. Always chock or block
wheels. Use jack stands to support the raised
machine. If the machine is not properly sup-
ported by jack stands, the machine may move or
fall, which may result in personal injury.
3. Chock rear wheels and jack up front of machine (see
Jacking Instructions in Chapter 1 -- Safety). Support ma-
chine with suitable jack stands.
4. Tilt the cutting deck upright to allow front wheel re-
moval (see Operator's Manual).
5. Remove front wheel assembly.
6. Remove four (4) flange head screws that secure
brake assembly to planetary assembly (see Brake As-
sembly Removal in this Chapter).
7. Support hydraulic wheel motor to prevent it from fal-
ling. Remove two (2) cap screws that secure wheel mo-
tor to planetary assembly.
8. Support planetary assembly to prevent it from falling.
Loosen and remove flange head screws that secure
planetary assembly to frame. Remove planetary as-
sembly from machine.
Installation (Fig. 7)
1. Inspect gasket between brake and planetary assem-
blies. Replace as needed.
2. Position planetary assembly to machine. Install
flange head screws that secure planetary assembly to
frame. Torque screws from 75 to 85 ft- -lb (101 to 115
N- -m).
3. Secure brake assembly to planetary assembly with
four (4) flange head screws (see Brake Assembly Instal-
lation in this Chapter). Torque screws from 75 to 85 ft- -lb
(101 to 115 N- -m).

4. Secure hydraulic wheel motor to planetary assembly
with two (2) cap screws. Torque screws from 75 to 85 ft- -
lb (101 to 115 N- -m).
5. Install front wheel assembly.
Failure to maintain proper lug nut torque could
result in failure or loss of wheel and may result in
personal injury.
6. Lower machine from jack stands. Torque wheel lug
nuts from 85 to 100 ft- -lb (115 to 135 N- -m).
7. Pivot the cutting deck down (see Operator's Manu-
al).
8. Make sure drain plug is installed in bottom of brake
assembly (Fig. 8). Fill planetary wheel drive/brake as-
sembly with SAE 85W--140 gear lube. Capacity is
approximately 16 fl. oz. (0.47 l) per wheel.
9. Check for proper brake operation.
