PRODUCT CARE
NOTE: Continue to check the front-to-back leveling as
you make the side-to-side adjustment as the side-to-side
adjustment can affect the front-to-back level. If necessary,
adjust front-to-back.
5. When proper adjustment is achieved, re-tighten the jam nuts
(b). Tighten to 57 ft-lbs (77 N-m). See Figure 32 on page 25.
LEVELING THE DECK PITCH/FRONTTOREAR
The front of the deck should be between 1⁄16-1⁄4” (2-6 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. 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 1⁄16-1⁄4” (2-6 mm)
less than the second measurement.
4. Determine the approximate distance necessary for proper
adjustment and proceed, if necessary.
5. To raise the front of the deck, remove the end cap, loosen
the outer jam nut (a) then tighten (thread inward) the inner
nut (b) against the front hanger bracket. See Figure 33. When
proper adjustment is achieved, re-tighten the outer jam nut
(a) and replace the end cap.

6. To lower the front of the deck, remove the end cap, loosen
the outer jam nut (a) then loosen (thread outward) the inner
nut (b), away from the front hanger bracket. See Figure 33.
When proper adjustment is achieved, re-tighten the outer
jam nut (a) to 57 ft-lbs (77 N-m) and replace the end cap.
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 1⁄4-1⁄2” (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 section
for instructions.
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.
PARKING BRAKE ADJUSTMENT
If the tractor does not come to a complete stop when the control
pedals are in the neutral position, engaging the parking brake,
or if the tractor’s rear wheels can roll with the parking brake
engaged (and the hydrostatic relief valve open), the brake is in
need of adjustment. See your authorized dealer to have the brake
properly adjusted.
DECK REMOVAL
Remove the tractor deck from the tractor as follows:
1. Move the tractor to a level surface, disengage the PTO, stop
the engine, place the drive pedals in the neutral position and
engage the parking brake.
2. There are two methods for removing the belt, to remove the
belt by releasing belt tension go on to Step 3, to remove the
belt by rolling the belt off the PTO pulley skip ahead to Step 4.
WARNING
Use caution to avoid pinching your fingers when rolling
the belt off the PTO pulley.
3. Releasing belt tension with the idler pulley:
a. Using the deck lift pedal and knob, raise the deck to the
position that provides the most horizontal run of the belt
between the deck idler pulleys and the PTO pulley on the
bottom of the engine. See Figure 34 on page 27.
b. Working from the middle of the tractor, pivot the idler
bracket (a) and movable idler pulley (b) rearward just far
enough to lift the belt up and over the spindle pulley.
See Figure 34 on page 27.
