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.
Parking Brake Adjustment
If the tractor does not come to a complete stop when the control levers are moved
fully outward 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 service dealer to have the brake
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 RH and LH drive control levers fully outward into the park brake engaged
position.
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 handle or the
deck lift pedal
and knob, raise
the deck to the

provides the most
horizontal run of
the belt between
the deck idler
pulleys and the
PTO pulley on the

to grasp the belt at the front of the PTO pulley.
c. Pull the left side of the belt rearward and downward while manually
turning the PTO pulley to the right until the belt rides out onto the
edge of the lower sheave of the pulley.
Note: If pulling the right side of the belt, turn the pulley left.

deck lift knob is spring-assisted
and under tension. Injury can
occur if spring-assisted deck lift
is released suddenly. Always use
the multi-tool to secure the deck
lift in place.
5. On tractors equipped with the
deck lift knob, use the deck lift
pedal and deck lift knob to place
the deck in the lowest position
and use the multi-tool (a) to lock
the deck lift components in place
as shown in Figure 44. On
tractors with a deck lift
handle, lower the deck
into the lowest position.
