Leveling the Mower Deck
When correctly adjusted the mower deck should be level side to
side, and the front of the deck should be approximately 1⁄4" lower
than the rear of deck.
NOTE: Check the tractor's tire pressure before performing any
deck leveling adjustments. See the tire side wall for proper
inflation pressures.
Side to Side Leveling
1.
If the cutting deck appears to be mowing unevenly, a side to
side adjustment can be performed. Adjust if necessary as
follows:
2.
With the tractor parked on a firm, level surface, place the deck lift
handle in the top notch (highest position) and rotate both
outer blades so that they are perpendicular to the tractor
frame.
3.
Lower the deck to the middle height position.
4.
Measure the distance from the outside left blade tip to the
ground and the distance from the outside right blade tip to
the ground. The measurements should be equal. If they're
not, proceed to the next step.
5.
Comparing the two measurements, determine whether the
left side of the deck must be raised or lowered.
6.
Loosen, but do not remove, the hex cap screw on the left
deck hanger bracket. See Figure 6-6.

7.
Level the deck by using a wrench to turn the adjustment
gear (found immediately behind the hex cap screw just
loosened) clockwise to raise the left side of the deck, or
counterclockwise to lower the left side of the deck. See
Figure 6-6.
8.
The deck is properly leveled when left and right blade tip
measurements are equal.
9.
Retighten the hex cap screw on the left deck hanger
bracket when proper adjustment is achieved.

1.
The front of the deck should be approximately
rear of the deck. Adjust if necessary as follows:
2.
With the deck raised off of the ground, rotate the outer blades so
that they are parallel to the frame of the tractor.
3.
If the side to side leveling was done correctly, measuring just the
right blade should be acceptable to attain the correct back
to front pitch of the deck.
4.
Measure the distance from the front tip of the blade to the
ground and the distance from the rear tip to the ground.
The front distance should be approximately 1⁄4" less than
the rear. If it is not, proceed to the next step.
5.
From the front of the tractor, loosen the outer hex nuts on the
deck front hanger rod and turn them away from the inner
nuts. Refer to Figure 6-7.

6.
If the front of the deck was too low, turn the inner hex nuts
clockwise against the hanger bracket to shorten the front
hanger rod and raise the front of the deck. Refer to Figure
6-7.
7.
If the front of the deck was too high, turn the hex nuts
counterclockwise to lengthen the front hanger rod and
lower the front of the deck.
NOTE: The deck front hanger rod should be at the front of
the slots of the front deck bracket. If one side of the rod is
not at the front of its slot, turn the inner hex nut on that
side until rod just touches the front of the slot. Then re-
measure and re-adjust the front hanger rod as necessary.
8.
When the correct pitch of the deck is acquired, secure the inner
hex nuts with a wrench and tighten the outer hex nuts
against the inner hex nuts to lock them in the adjusted
position.
