10. Push a 5/32” x 1-1/2” (4mm x 40mm) cotter pin
through the gap, coming up from the bottom. Bend
both ends of the cotter pin down around the hinge
loop. See Figure 4.16.
11. Confirm that the grass door pivots freely, fits properly
against the grass bag, and closes fully.
12. Test run the mower in a safe area and check all of
the safety features before returning it to service. Do
not put an unsafe mower into service.
Front Wheels
All of the wheels (drive and non drive) are held on with
nylock nuts.
To remove/replace a wheel:
1. Loosen the nut that secures each wheel that is to be
removed, using a 9/16” wrench.
2. Lift and safely support the mower so that the wheel or
wheels to be removed are off the ground.
3. Remove the wheel nut. See Figure 4.17.
4. Slide the wheel off of the axle. Capture the washers
on the front wheels, if they are present.
5. The front wheels may have special double-beveled
washers between the wheel and the nut.
See Figure 4.18.
6. Install the wheel by following the previous steps in
reverse order.
NOTE: Service wheels may not need the washer. Check
the fit of the wheel on the axle to see if the washer
is needed.
NOTE: Apply a small amount of a dry lubricant such as
graphite or PTFE (Tefflon) to the axle shaft before
sliding the wheel on.
NOTE: Apply a small amount of releasable thread locking
compound such as Loctite® 242 (blue) to the lock
nut or replace it with a new one.
NOTE: Tighten the wheel nuts to a torque of 80-100 in lbs
(9-11 Nm)
