2. Check the air pressure in the tyres. If the air
pressure is incorrect, the mower housing will
not cut level. The correct air pressure is:
Front Tyres 1,38 BAR (20 PSI), Rear Tyres
0,97 BAR (14 PSI).
3. If equipped, remove the gauge wheels.

5. (Figure 19) Loosen the left and right ad-
juster knobs (1). Push down on each side of
the mower housing. Make sure both sides of
the mower housing are setting on a flat sur-
face. Also, make sure the lift links (2) are
loose and can easily move up or down
6. Push down on the lift links (2) and tighten
the left and right adjuster knobs (1). If
necessary, use a wrench to tighten the ad-
juster knobs (1)
7. (Figure 18) Raise the lift lever (1).

is not level, repeat the above steps.
Where To Lubricate (Figure 16)
Lubricate the areas shown
with engine oil.
Apply grease with a brush to
the areas shown.
Models with grease fittings:
Lubricate with grease gun.
NOTE: Apply grease to the steering gear as-
sembly.
CAUTION: If the unit is operated in dry areas
that have sand, use a dry graphite spray to
lubricate the unit.
Check The Tyres
Check the air pressure in the tyres. Tyres with too
much air pressure will cause the unit to ride rough.
Also, the wrong air pressure will keep the mower
housing from cutting level. The correct air pres-
sure is: Front Tyres 1,38 BAR (20 PSI), Rear
Tyres 0,97 BAR (14 PSI).
