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 inch
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
If the cutting deck appears to be mowing unevenly, a side to side
adjustment can be performed. Adjust if necessary as follows:
1.
With the tractor parked on a firm, level surface, place the
deck lift handle in the top notch (highest position) and
rotate both blades so that they are perpendicular to the
tractor frame.
2.
Lower the deck to the middle height position.
3.
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.
4.
Comparing the two measurements, determine whether the
right side of the deck must be raised or lowered.
5.
Loosen, but do not remove, the hex screw on the left deck
hanger bracket. Refer to Fig. 6-5.

6.
Level the deck by using a wrench to turn the adjustment
gear (found immediately behind the hex screw just
loosened) clockwise to lower the left side of the deck, or
counterclockwise to raise the left side of the deck. See Fig.
6-5.
7.
The deck is properly leveled when both blade tip
measurements taken earlier are equal.
8.
Retighten the hex cap screw on the right deck hanger
bracket when proper adjustment is achieved

Front to Back Leveling
The front of the deck should be approximately 1⁄4" lower than the
rear of the deck. Adjust if necessary as follows:
1.
With the deck raised off of the ground, rotate the outer
blades so that they are parallel to the frame of the tractor.
2.
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.
3.
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.
4.
If the front of the deck was too low, turn the flange lock
nuts clockwise against the hanger bracket to shorten the
front hanger rod and raise the front of the deck. Refer to
Fig. 6-6.

5.
If the front of the deck was too high, turn the flange lock
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 flange lock 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.
