Traction Neutral Switch; Seat Sensor - Toro Reelmaster 5500-D Service Manual

Traction Neutral Switch

The switch is located on the right side of the transmis-
sion. It uses its normally open contact that is closed by
the switch arm depressing the plunger when the traction
pedal is in the neutral position. When the traction pedal
is depressed in either the forward or reverse direction,
the switch arm releases the plunger on the switch and
its normally open contact opens.

Seat Sensor

The sensor consists of two parts. The reed switch is lo-
cated on the lower bracket of the seat suspension mech-
anism and has a normally open contact. The switch
actuator is located on the upper plate of the seat suspen-
sion mechanism and is made of a magnetic material.
When the operator sits in the seat, the magnetic field of
the actuator is positioned near the reed switch and the
contact in the switch closes. The switch has a electrical
connector that can be accessed when the seat is raised.
1. Raise the seat to get access to the seat sensor wiring
connector.
2. Disconnect the seat sensor wiring connector and
install a continuity tester or ohm meter between the two
leads of the seat sensor.
3. Lower the seat. The continuity tester should show no
continuity.
Note: Make sure the compression spring holds the
seat up off the seat sensor when there is no operator on
the seat.
4. Have the operator sit on the seat, slowly depressing
the seat sensor magnet. The continuity tester should
show continuity as the seat approaches the bottom of its
travel.
