LEVELING THE DECK (FRONT TO REAR)
NOTE: Check the tractor's tire pressure before performing any
deck leveling adjustments. Refer to 'Tires' for information re-
garding tire pressure. Always level the deck side to side before
front to rear.
The front of the deck should be between 1⁄4-3⁄8" 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 handle in a middle position.
2. Rotate the blade nearest the discharge chute so that it is
parallel with the tractor.
3. 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 1⁄4" and 3⁄8" less than
the second measurement.
4. Determine the approximate
distance necessary for proper
adjustment and proceed, if nec-
essary.
5. Using a wrench, raise or lower
the front of deck by turning lock
nut on the front deck lift rod.
See Figure 24.
6. The deck is properly leveled when the front tip of the blade
is 1⁄4" lower than the rear tip. Retighten the hex bolt on the
left rear deck hanger links when proper adjustment is achieved.
ADJUSTING THE FRONT GAUGE WHEELS
WARNING: Keep hands and feet away from the discharge
opening of the cutting deck.
The front gauge wheels on the mower deck are an anti-scalp
feature, and should not ride on the ground. The front gauge
wheels should be approximately 1⁄4-1⁄2" above the ground
when the deck is set in the desired height setting.
Using the lift handle, set the deck in the desired height setting
then check the gauge wheel distance from the ground below. If
necessary adjust the front gauge wheels as follows:
1. Visually check the distance between the front gauge wheels
and the ground. If the gauge wheels are near or touching the
ground, they should be raised. If more than 1⁄2" above the
ground, they should be lowered.
2. Remove the lock nut securing
one of the front gauge wheel
shoulder screws to the deck.
Remove the gauge wheel and
shoulder screw. See Figure 25.
3. Insert the shoulder screw into the one of four index holes in
the front gauge wheel bracket that will give the gauge wheel
a 1⁄4-1⁄2" clearance with the ground.
4. Note the index hole of the just adjusted wheel, and adjust
the other front gauge wheel into the respective index hole of
the other front gauge wheel bracket.

DRIVE CONTROL LEVER STOP ADJUSTMENT
When the drive control levers are both fully extended forward
to the full-speed position and the tractor drifts left or right, the
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 trac-
tor is drifting to and adjust the
opposite drive control lever. If
the tractor drifts right, adjust
the left control lever down (de-
crease speed) and vice versa.
2. Locate the drive control lever
stop adjustment bolts on the
front of the seat frame. See Fig-
ure 26.
3. To decrease the forward speed, turn the bolt clockwise. To
increase the forward speed, turn the bolt counterclockwise.
Turn the bolt in the necessary direction 1⁄4-turn at a time. After
turning the bolt, 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.
SERVICE
BATTERY REMOVAL
The battery is located beneath
the seat frame. To remove the
battery:
1. Remove the hex washer screw
securing the battery hold down
bracket to the frame. Then flip
the battery hold-down bracket
up to free the battery. See Fig-
ure 27.
2. Remove the hex cap screw and nut securing the black nega-
tive battery lead to the negative battery post (marked NEG).
Move the cable away from the negative battery post.
3. Remove the hex cap screw and nut securing the red positive
battery lead to the positive battery post (marked POS).
4. Carefully lift the battery out of the tractor.
5. Install the battery by repeating the above steps in the reverse
order.
WARNING: Always connect the positive lead to the battery
before connecting the negative lead. This will prevent sparking
or possible injury from an electrical short caused by contacting
the tractor body with tools being used to connect the cables.
SERVICING 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.
