ELECTRICAL SYSTEMS
KeyChoice™ Reverse Operating
System Switch

Purpose

This switch is used in the KeyChoice™ Reverse
Operating System circuit. When turned to the ON
position, it allows the operator to mow in reverse.

How It Works

The switch is basically an on/off switch spring loaded to
return to off position. When turned to the ON position
with the PTO engaged, it activates circuits in the
KeyChoice™ Reverse Operating System reverse
module and allows the operator to mow in reverse
(Figure 252).
Figure 252

Testing

1. Disconnect the switch from the circuit.
2. With a mulitmeter, check the continuity across the
two terminals.
3. Turn the key to the "ON" position and hold, since
the switch is spring loaded. There should be
continuity across the two terminals.

Reverse Switch
(Hydrostatic Models)
Purpose
This switch works in the KeyChoice™ Reverse
Operating System circuit when the mower (PTO) is
engaged.

Location

The switch is located in the right rear corner of the
tractor. To obtain access to the switch, remove the
rear panel. The switch is mounted to the bottom of the
cruise control bracket (Figure 253).
How It Works
MBC-422X
This single pole plunger type switch has two terminals.
When the unit is shifted in reverse while the mower
(PTO) electric clutch is engaged, the reverse switch
opens and will stop the electric (PTO) clutch, unless
the KeyChoice™ switch has been operated.
Testing
1. Disconnect the switch from the wiring circuit.
2. With a multimeter, check the continuity across the
terminals. There should be continuity.
