Servicing Electrical System
FUSE
Fuses can be found by lifting the operator's seat. Most of the fuses are in the main
power distribution module (PDM) to the right of the battery (see Figure 42 for fuse
layout and Figure 43 for fuse assignments). These are standard mini type (ATM)
plug-in automotive fuses. Always use the same capacity fuse for replacement. Two
additional fuses, the Electronic Power Steering (EPS) and Alternator, are in single
MAXI fuse holders near the main PDM.
If you have a recurring problem with blown fuses, have the mower's electrical system
checked by an authorized service dealer.

Safety Interlock System & Switch Operation Checks
The following operational checks should be made daily:
PTO SWITCH
1. Sit in the operator's seat. With the drive pedals in the neutral position and the
parking brake engaged, engage the PTO switch by pulling up on the knob and
try to start the engine. The engine should not start. If it does, the PTO switch
must be replaced. See your authorized service dealer.
2. If the engine does not start, disengage the PTO by pressing the knob down and
start the engine. Now engage the PTO and the blades should rotate.
3. If the blades do not turn, the PTO switch must be replaced, the seat switch
must be replaced or the electric PTO clutch must be repaired. See your
authorized service dealer.
PARKING BRAKE SWITCH
1. Sit in the operator's seat. With the drive pedals in the neutral position and the
PTO disengaged, release the parking brake and try to start the engine. The
engine should not start.
2. If it does, the parking brake switch must be repositioned or replaced. See your
authorized service dealer. If the engine does not start, engage the parking
brake and start the engine.

SEAT SWITCH
1. With the drive pedals in the neutral position, the parking brake engaged and
the PTO disengaged, start the engine. Now release the parking brake and raise
up off the seat. Release the operator's seat and the engine should stop. If the
engine does not stop, the seat switch must be replaced. See an authorized
service dealer.
2. With the drive pedals in the neutral position, the parking brake engaged and
the PTO disengaged, sit in the operator's seat and start the engine. Engage the
PTO and the blades should start to rotate. Raise up slightly off the operator's
seat and the blades should stop. If the blades do not stop when you dismount
from the operator's seat, the seat switch must be replaced. See your authorized
service dealer.
ELECTRIC PTO CLUTCH
1. This clutch operates when the engine is running, the operator is in the
operator's seat and the PTO is engaged. This electric clutch is normally a trouble
free device. If a problem develops and the blades do not turn, first check the
25 amp fuse, then investigate the wiring harness and the connections to the
seat switch, the PTO switch and the electric blade clutch. Then check the seat
switch, the PTO switch and finally the electric blade clutch. If the PTO clutch is
still not working properly, see an authorized service dealer.

2. Reinstall the tires using the four lug nuts. See Figure 44. Torque the lug nuts (a)
to 65-70 ft-lbs.
