MAINTENANCE
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
properly adjusted. Raise the deck to the highest
(transport) position.
The deck should be adjusted slightly higher in the
rear.
NOTE: To insure accuracy of leveling procedure,
mower deck drive belt must be installed prior to
leveling deck.
1. Wear heavy gloves. Turn each blade tip to align
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 this measurement.
3. Move to the opposite side, check that the
measurement is the same. If adjustment is
required—with a ¾" or adjustable wrench, turn
the lift link adjustment nuts on either side counter
clockwise to lower or clockwise to raise. Adjust
until both side-to-side measurements are equal.

4. Turn either blade to align with the deck in front-
to-rear manner. If the front blade tip does not
measure

/8" to ½" higher in the rear, follow the
front adjustment instructions that follow.
5. With a
5
/8 or adjustable wrench, turn the nuts on
the front suspension linkage. Clockwise raises the
front of the mower, counterclockwise will lower
the front. Adjust nuts until rear of mower deck is
positioned level to
1
/8" higher in the rear than the
side-to-side measurement.
NOTE: This will place the mower deck in a
standard measurement position. Depending on
the type of grass being mowed or environmental
conditions, additional adjustments may be
required to achieve the desired cut.
