If safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock
switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
• Replace switches every two years
regardless of whether they are operating
properly or not.
Verifying the Interlock Switch
Function
1. Park the machine on a level surface, lower the
cutting units, stop the engine, and engage the
parking brake.
2. Open control panel cover.
3. Locate the wire harness and connectors near
the controller (Figure 38).

6. Turn the key switch to the On position, but do
not start the machine.
Note: The red text on the overlay decal refers
to input switches and the green text refers to
outputs.
7. The "inputs displayed" LED, on the lower
right column of the Diagnostic ACE, should
be illuminated. If the "outputs displayed"
LED is illuminated, press the toggle button,
on Diagnostic ACE, to change LED to "inputs
displayed".
The Diagnostic ACE will illuminate the LED
associated with each of the inputs when that
input switch is closed.
8. Individually, change each of the switches from
open to closed (i.e., sit on seat, engage traction
pedal, etc.), and note that the appropriate LED
on Diagnostic ACE will blink on and off when
corresponding switch is closed. Repeat this for
all switches that you can change by hand.
9. If a switch is closed and the appropriate
LED does not turn on, check all wiring and
connections to the switch and/or check the
switches with an ohm meter. Replace any
defective switches and repair any defective
wiring.
