MAINTENANCE
Removing and Reinstaliing the Wheels
The mower’s wheels are secured to the wheel shaft
by a clevis pin and a clinch pin. Removing the wheels
is a simple matter. Occasionally, especially when
you’re mowing taller vegetation, you might find that
this vegetation tends to wrap around the wheels. To
remove this vegetation, take the wheel off by following
the instructions below. Then pull the vegetation off
and reinstall the wheel.
NOTE
If you had a difficult time removing the clevis pin
or the wheel, inspect the wheel shaft, clevis pin,
and inside surface of the wheel hub for corro­
sion or dirt. Clean any dirt away from these
areas. If there is any corrosion, use a fine grade
of sandpaper to remove it. Then apply grease to
the wheel shaft and clevis pin to prevent further
corrosion and to make future wheel removal
easier.
A CAUTION
Before removing or reinstalling a wheel, shut the
engine off, allow it to cool, disconnect the spark
plug wire and prevent it from touching the spark
plug, and reinstall the plastic blade protector on
the front of the blade. For electric start models,
also remove the Engine Ignition key from the key-
switch.
Failure to do this could result in personal injury
or property damage.
To remove a wheel;
1. Prop up the mower so that the wheel is supported
off the ground. Do this by placing a 5 or
6 -inch thick
block of wood beneath the mower.

2. Move the quick release pin’s round wire bail over
the wheel hub.
3. Insert your finger in the round wire bail. Pull the
pin out of the wheel hub. A small twisting motion
while you pull is helpful.
4. Carefully slide the wheel outward until it is off the
wheel shaft.
To reinstall the wheel:
1. Align the wheel hub with the wheel shaft and slide
the wheel onto the wheel shaft.
2. Rotate the wheel on the wheel shaft until the holes
in the wheel hub align with the hole in the wheel
shaft.
3. Insert the quick release pin through these holes.
4. Move the quick release pin’s round wire bail over
the wheel hub.
