5. To even the deck turn the adjustment
gear, located
immediately
behind the hex cap screw, clockwise
(rear-
ward) to lower the left side of the deck. Turn the gear
counter-clockwise
(toward front) to raise the left side of
the deck. See Figure 6-6.
6. The deck is properly
leveled when both blade tip mea-
surements,
as described
earlier, are equal.
7. Retighten the hex cap screw in the left deck adjust-
ment bracket when proper adjustment
is achieved.
FrontToRearDeckLeveling
The front of the cutting
deck is supported
by an adjustable
front deck hanger rod. This rod can be adjusted to set the
front to rear pitch of the deck. The front of the deck should
be approximately
1/4-inch lower than the rear of the deck.
Adjust if necessary as follows:
NOTE: The deck should first be leveled side to side. Check
the side to side level of the deck and adjust if necessary.
1. With the tractor parked on a firm, level surface, move
the deck to the mid height position
(third or fourth
notch) using the deck lift lever. Carefully rotate the RH
blade (nearest the discharge chute) so that it is parallel
with the tractor frame.
2. Measure the distance from the front of the blade tip to
the ground and the rear of the blade tip to the ground.
The front measurement
taken should be approximately
1/4" less than the rear measurement.
Determine
wheth-
er the front of the deck has to be raised or lowered.
3. Working
at the front of the tractor, loosen the two hex
lock nuts at the front of the deck hanger rod. Thread
the lock nuts away from the hex nuts behind them.
Refer to Figure 6-7.
4. Use a open end wrench to turn the inner hex nuts to
adjust the front of the deck. Turn the hex nuts clock-
wise to raise the front of the deck, or counterclockwise
to lower the front of the deck. Adjust the hex nuts
evenly so that the deck hanger rod is at the front of
both slots in the hanger bracket on the front of the
deck. See Figure 6-7.

Retighten
the two hex lock nuts when properly
adjusted.

Deck Gauge Wheel Adjustment
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.
The deck gauge wheels should neither contact the ground,
nor be high off the ground, when the deck is moved to the
desired height setting. If you change your cutting
height
during the mowing
season, the gauge wheels should be
checked and adjusted as necessary. Adjust the gauge
wheels as follows:
•
Place the tractor on a flat surface and move the deck to
the desired mowing
height using the deck lift lever.
•
Check gauge wheels distance from the flat surface
below. If the gauge wheels contact the ground, they
must be raised. If the gauge wheels are higher than 1/2"
above the ground, they should be lowered.
•
Remove the hex flange lock nut and shoulder bolt
securing one of the front ball wheels to the front index
bracket. Reposition the ball wheel to align with the one
of five index holes that places the wheel 1/4" to 1/2"
above the ground. Secure the ball wheel to the index
bracket with the shoulder bolt and flange lock nut. Note
the index hole used and secure the other ball wheel in
the same position. See Figure 6-8.
