Adjust the Gauge Wheels
The axle bolts for the gauge wheels were mounted in the
LOW cut position. To change the position of the gauge
wheels, move the axle bolts as follows.
IMPORTANT: Before you adjust the gauge wheels,
you must do the following. Make sure the mower
housing is level. Make sure the height of cut is set at
the height you want for your lawn. Mow a short dis-
tance on a flat level area and look at the area that was
cut. If the mower housing does not cut level, see
"Level the Mower Housing."
WARNING
Before you make an inspection, adjustment 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. Remove the gauge wheels (12) and axle bolts (11)
(see Figure 3).

2. Mow a short distance on a flat level area to check
the level of cut and the height of cut. Look at the
height of cut position number 3 on the lift lever (1)
(see Figure 17).
3. Look at each gauge wheel bracket (13) (see Figure
3). There are 3 holes in each bracket and is a number
next to each hole. The number for the height of cut
position on the lift lever indicates the correct hole to
use on each gauge wheel bracket.
NOTE: Wheel bracket hole number 1 is equal to lift
lever position number 1. Wheel bracket hole number
2 is equal to lift lever position number 2. Wheel
bracket hole number 3 is equal to lift lever position
numbers 3, 4, 5 and 6.
4. Assemble the axle bolts (11) to the gauge wheel
brackets (13) using the correct hole in the bracket
as indicated.
NOTE: If the height of cut position is changed by the
lift lever, you must move the gauge wheels to the
correct hole to keep a level height of cut.

Level the Mower Housing
If the mower housing is level, the blade will cut easier and
the lawn will look better.
Before you make an inspection, adjustment 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 incorrect, the mower housing will not
cut level. Make sure the tires are inflated to: Front
Tires 0,97 BAR (14 PSI), Rear Tires 0,69 BAR
(10 PSI).
3. Move the lift lever (1) to the lowest cut position (2)
(see Figure 17).
The lift lever is spring loaded. Make sure the lift
lever is locked in the lowest cut position.
Figure 17
4. Loosen the left and right adjuster knobs (1) (see
Figure 18). Push down on each side of the mower
housing. Make sure both sides of the mower housing
are sitting on a flat surface. Also, make sure the lift
links are loose and can easily move up or down.
5. Push down on the lift links (2) and tighten the left and
right adjuster knobs. Make sure the adjuster knobs
are tight. If necessary, use a wrench to tighten the
adjuster knobs.
6. Raise the lift lever (1) (see Figure 17).
7. Mow for a short distance. If the height of cut is not
level, repeat the above steps.
