Do not disconnect safety switches. They are for the operator's
protection. Check the operation of the interlock switches daily for
proper operation. Replace any malfunctioning switches before
operating the machine.
Your Groundsmaster is equipped with two (2) Toro Electronic Controllers
(TEC) which monitor interlock switch operation. If all of the interlock switches
necessary to allow a specific machine operation are not in their desired position,
an Operator's Advisory will appear on the Info- Center Display (see
Advisories (page 3–16)).
The interlock system used on your Groundsmaster includes the seat switch, the
traction pedal position sensor, the parking brake switch, the cutting deck position
switches, the mow/transport switch and the PTO switch.
Use the InfoCenter Display to test the various interlock switches (TEC inputs and
outputs) before physically testing the switch and its circuitry (see
Display (page 6–9)). Physically testing individual interlock switches is included in
the Testing (page 6–56).
