SECTION6: MAKINGADJUSTMENTS
WARNING: Shut the engine off, remove
the ignition key and engage the parking brake
before making adjustments. Protect your
hands by using heavy gloves when handling
the blades.
Levelingthe Deck
NOTE: Check the tractor's tire pressure before
performing any deck leveling adjustments. Refer to
Tires on page 25 for information regarding tire pressure.
FrontTo Rear
The front of the cutting deck is supported by a stabilizer
bar that can be adjusted to level the deck from front to
rear. 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:
• Park the tractor parked on a firm, level surface and
place the deck lift lever in the top notch.
• 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 distance necessary for
proper adjustment and proceed, if necessary.
• From the front of the tractor, loosen the hex lock nut
on each end of the deck hanger rod, and turn away
from the inner hex nuts. See Figure 10

NOTE: Some models have an extruded hanger
bracket with a pivot cup, and only one hex nut and lock
nut. Adjust using the same procedure.

• Tighten the inner hex nuts front against the front
hanger bracket to raise the front of the deck; loosen
the hex nuts to lower the front of the deck. See
Figure 10.
• Retighten the two lock nuts against the inner hex
nuts when proper adjustment is achieved.
Sideto Side
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
outside 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 bolt on the left
deck hanger bracket. See Figure 11.

• Raise and lower the left side of the deck by using a
wrench to turn the adjustment gear. See Figure 11.
• The deck is properly leveled when both blade tip
measurements taken earlier are equal.
• Retighten the hex bolt on the left deck hanger
bracket when proper adjustment is achieved.
