Front to Back Leveling.
The front of the deck should be approximately 1/8 to
1/4 inch lower than the rear of the deck. Adjust if nec-
essary as follows:
• With the deck raised off of the ground, rotate the
blades so that they are parallel to the frame of the
tractor.
• 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.
• 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 1/8 to 1/4 inch less than the rear. If it is not,
proceed to the next step.
• From the front of the tractor, on the rearward side
of the front hanger rod bracket, locate the two
hex jam nuts on the deck front hanger rod. See
Figure 29.

• Loosen the two hex jam nuts and turn them away
from the backside of the front hanger rod bracket.
• If the front of the deck was too low, turn the hex
flange nuts on the ends of the front hanger rod
clockwise to raise the front of the deck. See
Figure 29.
• If the front of the deck was too high, turn the hex
flange nuts counterclockwise to lower the front of
the deck.
IMPORTANT: 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 hex flange nut on the that side
until rod just touches the front of the slot. Then
re-measure and re-adjust the front hanger rod as
necessary.

• When the correct pitch of the deck is acquired,
tighten the hex jam nuts against the front hanger
rod bracket.
ADJUSTING THE GAUGE WHEELS
The cutting height of the mower deck can be set in
any of six height settings using the deck lift handle of
the tractor. The deck heights range from 1-1/2 inches
to 4 inches. The deck gauge wheel position should be
approximately 1/4 to 1/2 inch above the ground when
the deck is set in the desired height setting.
WARNING: Keep hands and feet away
from the discharge opening of the
cutting deck.
NOTE: The deck gauge wheels are an anti-scalp
feature of the deck and are not designed to support the
weight of the cutting deck.
Using the lift handle, set the deck in the desired
height setting, then check the gauge wheel and if
necessary adjust as follows.
• With the deck set at the desired height, visually
check the distance between the gauge wheels
and the ground. If the gauge wheels are near or
touching the ground, they should be raised. If the
gauge wheels are too high, they should be
lowered.
• Remove the lock nut securing one of the gauge
wheel shoulder screws to the deck. Remove the
gauge wheel and shoulder screw. See Figure 30.
