Parking Brake Switch - Toro Reelmaster 2000-D Service Manual

Parking Brake Switch

The parking brake switch is a normally open proximity
1
switch that is mounted on a bracket at the base of the
parking brake lever (Fig. 23). The parking brake lever is
used as the sensing plate.
When the parking brake is engaged, the brake lever is
moved away from the brake switch and the switch
opens. This open switch prevents the cutting units from
operating.

The Standard Control Module monitors the operation of
the parking brake switch. If the ignition switch is in the
ON position and the parking brake is not applied, the
Module brake off input LED should be illuminated.
Parking Brake Switch Test
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
