Adjusting the Mower Deck

Leveling deck
Adjust the deck while the mower is on a level
surface. Make sure the tires are inflated to
the correct pressure. See Technical Data /
Transmission. If tires are under or over inflated,
the deck cannot be correctly adjusted. Raise the
deck to the highest (transport) position.
The deck must be adjusted slightly higher in the
rear.
NOTE: To insure the precision of the leveling
procedure, the mower deck drive belt must be
installed before leveling the deck.
1. Wear heavy gloves. Turn each outer blade tip
to align with the deck side-to-side.
2. Measure from the floor surface up to the
bottom of the blade tip on the discharge side
of the mower deck. Record the measurement.
3. Move to the opposite side, check that
measurement is the same. If adjustment is
required—with a 3/4" or adjustable wrench,
turn the lift link adjustment nuts on either
side counter clockwise to lower or clockwise
to raise. Adjust until both measurements are
equal.
4. Turn either blade to align with the deck front-
to-rear. If the front blade tip does not measure
1/8" to 1/2" higher in the rear—with a 5/8" or
adjustable wrench, turn the nuts on the front
