Seat Switch

Purpose

The seat switch is a part of the safety interlock system.
If the engine is running and the operator vacates the
seat with the PTO engaged and/or the handles pulled IN,
the engine will shut off.

Location

The seat switch is attached to the seat base, accessible
by flipping the seat up into the service position.
To remove the seat switch, first disconnect the harness
connection from the switch. Then rotate the switch
counterclockwise and remove switch from the seat base
(Fig. 151).

How It Works

With the ignition switch ON, and the seat switch closed,
it supplies voltage to the Brake Actuator Module (pin 7)
and the hour meter (Fig. 152).

Testing

1. Disconnect the harness connection from the seat
switch.
2. With a multimeter set to the Ohm or Continuity
setting, check the continuity between the two switch
terminals:
- When the seat is vacated, the switch should
be OPEN and there should be NO continuity
between the two switch terminals.
- When the seat is occupied, the switch CLOSES
and there should be continuity between the two
switch terminals.
