MOWER DECK LEVELING PROCEDURE
There are four(4) slots that will control the attitude or pitch of
the mower deck. The deck should be level or pitched slightly
higher in rear.
1. Place the mower on a smooth level surface with front
casters positioned towards deck. Check tire pressures to
insure the mower has a correct stance. Inflate tires as
required:
Front 16 - 21 lbs maximum (110-145 kPa)
Rear: 8-14 lbs maximum (55-97 kPa)
NOTE: To insure accuracy of leveling procedure, mower deck
drive belt must be installed prior to leveling deck.
2. Wear heavy gloves. Turn each outer blade tip to align
with the deck or in a side-to-side manner.
3. Measure from the floor surface up to the bottom of the
blade tip on the discharge side of the mower deck.
Retain this measurement. Move to the opposite side,
check that measurement is the same. If adjustment is
required, loosen the locknut and move mounting bolt up
or down in slot until both side-to-side measurements are
equal. Retain measurement.
