Checking the
Safety-Interlock Switches
Service Interval: Before each use or daily
The machine has interlock switches in the electrical
system. These switches disengage either the traction
unit or the PTO whenever you leave the seat. If you
disengage the PTO and engage the parking brake
before you leave the seat, the engine continues to run.
1. Drive the machine slowly to a large, open area.
Lower the mower deck, shut off the engine, and
apply the parking brake.
2. Sit on the seat and press the traction pedal. Try
to start the engine. The engine should not start.
If the engine starts, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
3. Sit on the seat, start the engine, and engage
the PTO. While sitting in the seat with the
PTO engaged, rise from the seat. The PTO
should disengage after a slight delay. If the
PTO engages, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
4. Sit on the seat, engage the parking brake and
start the engine. Move the traction pedal out of
the N position. The InfoCenter should
EUTRAL
display "traction not allowed" and the machine
should not move. If the engine does move, there
is a malfunction in the interlock system that
should be corrected before beginning operation.
