WARNING: Maintaining correct air pressure in the tires is very important. Too little pressure could allow the tire to
rotate off the wheel rim. Too much pressure could cause the tire to burst. Failure to maintain correct air pressure in the
tires could cause problems with mower operation and stability, causing serious personal injury.
REPLACING THE WHEELS
NOTICE: The following tools (not included) are required for replacing the wheels:
◾
Automotive jack
◾
Jack Stand
◾
Wheel chocks
◾
Open-end wrench or adjustable wrench. Required size are 13/16 in (21mm) and 23/32 in (18 mm)
◾
Torque wrench with 13/16 in (21mm) socket
◾
Flat-blade screwdriver
WARNING: If raising the mower, make sure that the mower is properly secured and the parking brake is set before
proceeding. Failure to properly secure the mower could cause it to fall, resulting in death or possible serious personal
injury.
To Replace the Front Wheel (Fig. 43)
Check the wheels at 200 hour intervals. Check that the front wheels
turn freely. If a wheel does not turn freely, replace it.
1. Raise the arm of the wheel that requires replacement using an
automotive jack. Use only recommended jack point shown in
Fig. 43.
2. Use the 23/32 in (18 mm) wrench (not included) to stablize the
screw first and then loosen and remove the nut on the other
side with a 13/16 in (21mm) wrench.
3. Pull the wheel in a forward or downward direction, out of the
yoke (Fig. 44). Replace the front wheel.
4. When installing the new wheel, take care of the nut direction
and tighten it with a torque wrench (see Fig. 43). The
recommended torque for the front wheel nut is 66-70 ft-lb
(90-95 Nm).
