Safety Interlock System and 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 your authorized
service dealer.

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 a normally 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.
