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 an 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 an 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 an 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 fingers when rolling the belt off
the PTO pulley.
3. Release belt tension:
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.
b. Remove the idler spring from the wireframe
spring hook on the right side of the center of
the deck. See Figure 45.
4. Roll the belt off the PTO pulley:
a. 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.
b. Sitting behind the tractor facing forward, reach
beneath the tractor 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.
d. While still holding the PTO
belt (a) downward, continue
turning the PTO pulley (b)
until the PTO belt (a) is
rolled off the PTO pulley (b).
Refer to Figure 46.
e. Lower the deck into the
lowest mowing position.
WARNING: The deck lift
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. Do not attempt to use the deck lift
pedal while the deck is locked with the multi-tool in this way.

Install the deck on the tractor as follows:
nOTE: To line the brackets up properly, it may be necessary to place a small block of
wood under each side of the deck.
5. Use the deck lift pedal and deck
lift knob to place the deck in the
lowest position and use the multi-
tool to lock the deck lift
components in place. There are a
pair of alignment holes by the rear
wheel on the left side of the tractor
(one on the frame and one on the
deck lift arm) as shown in Figure
47. Ensure tool is fully inserted
properly, locking the deck lift arm
in place to the frame.
6. Remove the two bow-tie pins from
the deck rods that secure the front
center lift link brackets on the
frame to the front-center lift
brackets on the deck and pull the
front end of the rods out of place.
See Figure 48.
7. Remove the deck stabilizer bar at
the rear of the deck:
a. Remove the bow-tie cotter
pin on the right side of the
bar connecting the bar with
the bracket on the deck. See
Figure 49.
b. Remove the bow-tie cotter
pin on the left side of the bar,

bracket on the frame. See
Figure 50.
8. Remove the bow-tie pin from
the bottom clevis end of each
deck height adjust rod. There is one at the front and one at the rear on each side of
the deck. See Figure 51 (left side shown).
9. Carefully maneuver the deck out from beneath the tractor.
1. Carefully manuever the deck under the tractor from the right side, lining up the deck
hanger rods and the deck lift rods on the tractor removed in the previous section with
appropriate bracket connections on the top of the deck.
2. Once the deck is under the tractor, move the deck to the lowest mowing position.
