The front of the deck should
be
between 1/4-inch and
3/8-inch lower than the rear
of
the deck. Adjust if
necessary
as
follows:
•
•
•
•
•
With the tractor parked
on
a firm, level surface,
place the deck
lift lever
in
the top notch (highest
position) and rotate the blade nearest the discharge
chute so that
it
is parallel with the tractor.
Measure the distance from the front of the blade tip
to the ground and the rear of the blade tip to the
ground.
The first measurement taken should
be
between
1/4" and 3/8" less than the second measurement.
Determine the approximate
C&stance
necesiary for
proper adjustment and proceed, if necessary, to the
next step.
Locate the two
lock nuts
on
the opposite side of the
stabilizer bracket.
See Figure 13A. Tighten the lock
nuts to raise the front of the deck; loosen the lock
nuts to lower the front of the deck.

If the cutting deck appears to
be
mowing unevenly, a
side to side adjustment can
be
performed. Adjust if
necessary as
follows:
•
With the tractor parked
on
a firm, level surface,
place the deck
lift lever in the top notch (highest
position) and rotate both blades so that they are
perpendicular with the tractor.
• Measure the distance from the outside of the left
blade tip to the ground and the distance from the
o(Jtside
of the right blade tip to the ground. Both
measurements taken should
be
equal. If they're not,
proceed to the next step.
• Loosen, but do NOT remove, the hex cap screw
on
the left deck hanger bracket. See Figure 13B.

Balance the deck by using a wrench to turn the
adjustment gear (found immediately behind the hex
cap screw just loosened) clockwise/up or
counterclockwise/down. You
will need
an
adjustable wrench for this step.
The deck is properly balanced when both blade tip
measurements
taken. earlier are equal.
Retighten the hex cap screw
on
the left deck hanger
bracket when proper adjustment
is
achieved.
