HOW TO LEVEL THE MOWER HOUSING
If the mower housing is level, the blade will cut easier and the lawn
will look better.
WARNING: Before you make an inspection, adjust-
ment, or repair to the unit, disconnect the wire to the
spark plug. Remove the spark plug wire to prevent
the engine from starting by accident.
1. Make sure the unit is on a hard flat surface.
2. Check the air pressure in the tires. If the air pressure is incor-
rect, the mower housing will not cut level. The correct air pres-
sure is shown on the side of the tire.
IMPORTANT: On models equipped with gauge wheels, the
gauge wheels must be removed to correctly adjust the
level of the mower housing.
3. Some models have gauge wheels on the mower housing. If
equipped, remove the gauge wheels.
4. Open the
cover.
5. Move the
lift lever
to the LEVEL ADJUSTMENT position
(Figure 31).
WARNING: The lift lever is spring loaded. Make sure
the lift lever is locked in the LEVEL ADJUSTMENT
position.
6. Loosen the left and right
adjuster knobs
(Figure 32). Push
down on each side of the mower housing. Make sure both sides
of the mower housing are setting on a flat surface. Also, make
sure the lift links are loose and can easily move up or down.
7. Push down on the
lift links
and tighten the left and right
adjust-
er knobs
(Figure 32). Make sure the
adjuster knobs
are tight.
If necessary, use a wrench to tighten the
adjuster knobs.
Tighten to a torque of 10 foot pounds (13,5 N
−
m).
8. Raise the
lift lever
from the LEVEL ADJUSTMENT position to
a CUTTING HEIGHT position (Figure 33).
9. Close the
cover.
10. If equipped, install the gauge wheels.
11. Attach the spark plug wire to the spark plug.
12. Mow for a short distance. If the height of cut is not level, repeat
the above steps.
CAUTION: Do not operate with the mower housing in the
LEVEL ADJUSTMENT position. If you operate in the LEVEL
ADJUSTMENT position, the mower housing and blades can be
damaged.
