Adjusting The Mower Deck - Craftsman Z6100 Operator's Manual

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 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, 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
suspension linkage. Clockwise raises the front
of the mower, counter clockwise 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 position 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 get the desired cut.
