Check Operation Of Interlock Switches - Toro GroundsmasterR 4300-D Service Manual

Check Operation of Interlock Switches

CAUTION
The interlock switches are for the protection of
the operator and bystanders and to ensure cor-
rect operation of the machine. Do not bypass or
disconnect switches. Check the operation of the
interlock switches daily for proper operation. Re-
place any malfunctioning switches before oper-
ating the machine.
Interlock switch operation is described in the Traction
Unit Operator's Manual. Your Groundsmaster is
equipped with a TEC controller which monitors interlock
switch operation. Information on the controller is de-
scribed in the Traction Unit Operator's Manual and in the
Component Testing section of this Chapter.
Electrical System
The interlock system used on your Groundsmaster in-
cludes the seat switch, the traction neutral switch, the
parking brake switch, the mow/transport switch and the
PTO switch. Testing of individual interlock switches is in-
cluded in the Component Testing section of this Chap-
ter.
NOTE: Use the Diagnostic Display (see Special Tools
in this chapter) to test TEC controller inputs and outputs
before further troubleshooting of an electrical problem
on your Groundsmaster.
