Seat Switch - Toro Groundsmaster 300 Series Service Manual

Seat Switch (Fig. 6, 7)
The seat switch is a normally open (N.O.) switch that
closes when the operator is on the seat. If the PTO
switch or traction switch is open and the operator raises
off the seat, the engine will stop.
1. Raise the seat to get access to the seat switch wiring
connector.
2. Disconnect the seat switch wiring connector and
install a continuity tester or ohm meter between the two
leads of the seat switch.
3. Lower the seat. The continuity tester should show no
continuity.
NOTE: Make sure the compression spring and pin holds
the seat up off the seat switch when there is no operator
on the seat.
4. Have the operator sit on the seat, slowly depressing
the seat switch. The continuity tester should show con-
tinuity as the seat approaches the bottom of its travel.
(See Replacing Seat Switch in Repairs section of this
chapter for replacement and adjustment procedures.)
