To Replace the Rear Wheel (Fig. 45)
The rear wheel for zero turn mower is a driving wheel. When it is
damaged, mower performance will be greatly affected. Replace it
immediately.
1. Restrain the movement of front wheels with wheel chocks.
2. Lift the affected side of the mower with an automotive jack at
the jack point shown in Fig. 44.
3. Insert the jack stand underneath the mower's frame. Lower
the automotive jack until the mower frame rests on the jack
stand.
4. Use a flat-blade screwdriver (not included) to pry and remove
the hubcap on the rear wheel.
5. Use the 13/16 in (21 mm) socket wrench (not included) to
loosen the four lug nuts (one turn for each nut).
6. Remove the four lug nuts on the rear wheel. Check the four
lug nuts and if they are in good condition, save them for
reassembly. Otherwise, replace them at the same time.
7. Pull the wheel off from the wheel studs. Replace the wheel.
8. When securing the new wheel, ensure the proper orientation
of the lug nuts – the tapered end against the wheel hub.
Finger-tighten the lug nuts (Fig. 46).
9. Lower the mower by reversing the steps 2 & 3. Tighten the lug
nuts in the order shown in Fig. 45 using a torque wrench. The
recommended torque for the rear wheel lug nuts is 74-76 ft-lb
(101–103 N m).
WARNING: Particular attention must be given to tightening the
wheel nuts, especially the drive-wheel lug nut. Failure to correctly
torque these items may result in the loss of a wheel, which can
cause serious damage or personal injury.
LUG NUTS ONLY - It is recommended that these be checked after
the first 2 hours of operation, initially, every 100 hours and following
removal for repair or replacement.
