SERVICE AND MAINTENANCE
Leveling the Deck (Side-to-Side)
1. Park the tractor on a firm, level surface.
2. Ensure that all tires are properly inflated.
3. Place the deck lift knob in a middle mowing position and rotate both outside
blades so that they are perpendicular with the tractor.
4. 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.
5. Locate the
adjustment
nuts on top of
the deck lift
rods on the left
and right side
of the tractor.
There is one
on each side at
the front of the
deck between
the platform
and lower
frame tube,
and one at each side of the rear of the deck near the front of the rear wheel.
See Figure 42.
6. Remove the end cap from front deck lift rods and save for later re-
installation.
7. Rotate either the left side (front and rear) or right side (front and rear) nuts
clockwise to raise the deck height or counter-clockwise to lower the deck,
depending on the needed adjustment. Adjust each nut equally.
Note: Make adjustments in quarter-turn increments, and remeasure blade distance
on both sides frequently.
Leveling the Deck (Pitch/Front-to-Rear)
The front of the deck should be between ⁄⁄” (3-9 mm) lower than the rear of the
deck. Adjust if necessary as follows:
1. Park the tractor on a firm, level surface and place the deck lift knob in a
middle position.
2. Ensure that all tires are properly inflated.
3. Ensure side-to-side level.
4. Rotate the blade nearest the discharge chute so that it is parallel with the
tractor.
5. 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 ⁄⁄”
(3-9 mm) less
than the second
measurement.
6. Determine the
approximate
distance necessary
for proper
adjustment
and proceed, if
necessary.
a. Remove
the end
cap on
both front deck height adjust rods and save for later re-installation.
See Figure 43.

b. Rotate both front nuts clockwise to raise the front deck pitch or
counter-clockwise to lower the front deck pitch, depending on the
needed adjustment. Adjust each nut equally. See Figure 43.
Note: Make adjustments in quarter-turn increments, and remeasure front-to-rear-
deck pitch blade distance frequently until proper pitch is achieved.
c. Reinstall the end caps onto the deck rods.
Adjusting the Deck Wheels
WARNING
Keep hands and feet away from the discharge opening of the cutting deck.
Note: The deck wheels are an anti-scalp feature of the deck and are not designed to
support the weight of the cutting deck. The deck wheels should be approximately
⁄⁄” (6.35-12.7 mm)above the ground when the deck is set in the desired height
setting. To adjust the deck wheels see the Assembly & Set-Up section for instructions.
Lapbar Drive Control Lever Stop Adjustment
When the lapbar drive control levers are both fully extended forward to the full-
speed position and the tractor drifts left or right, the lapbar drive control lever stop
adjustment can be adjusted to sync the wheel speeds. To perform the adjustment,
proceed as follows:
1. Identify the side that
the tractor is drifting to
and adjust the opposite
lapbar drive control
lever. If the tractor
drifts right, adjust the
left lapbar drive control
lever down (decrease
speed) and vice versa.
2. Locate the lapbar drive
control lever stop
adjustment bolts (a)
on the front of the seat
frame. See Figure 44.
Note: The multi-tool (if equipped) can be used to make this adjustment.
3. To decrease the forward speed, turn the lapbar drive control lever stop
adjustment bolts (a) clockwise. To increase the forward speed, turn the
lapbar drive control lever stop adjustment bolts (a) counter-clockwise. Turn
the lapbar drive control lever stop adjustment bolts (a) in the necessary
direction ⁄-turn at a time. After turning the lapbar drive control lever stop
adjustment bolts (a), check the adjustment by driving the tractor.
4. Continue the adjustment until the wheel speeds are in sync and the tractor
drives straight with the drive control levers fully extended forward in the
full-speed position.
Note: Make sure the bolts extend through the nuts on the frame to engage
the locking feature.
Service
Electrical System
A fuse is installed to protect the tractor’s electrical system from damage caused
by excessive amperage. Always use the same capacity fuse for replacement. If the
electrical system does not function, check for a blown fuse.
If you have a recurring problem with blown fuses, have the tractor’s electrical
system checked by your authorized service dealer.
Relays and Switches
There are several safety switches in the electrical system. If a function of the safety
interlock system described earlier is not functioning properly, have the electrical
system checked by your authorized service dealer.
