Cutting Unit Down Sensor(s)
The cutting unit down switch is a normally open (NO)
reed switch located on the left front lift arm that closes
when the liftarmis inthe loweredposition. Asthe liftarm
is lowered, a bracket on the lift arm comes close to the
switch, causing the reed switch to close and complete
the circuit.
This sensor can be tested using the “Input Checks” fea-
ture of the ACE Diagnostic tool.

Move the lift arm toward the switch as far as it will
move.
Note:
When the Enable/Disable switch is in ENABLE,
the controller uses inputs from this switch to turn the
cutting units on and off. When raising the cutting units
with the Enable/Disable switch in ENABLE, the cutting
units lift part way to a “turn around” position.
