Front Reels Down Sensor (Serial Number Below 230000000)
On machines with serial numbers below 230000000,
the front reels down sensor consists of two parts. The
reed switch is located on the left end of the carrier frame
and has a normally open contact. The switch actuator is
located on the left lift arm and is made of a magnetic ma-
terial. When the front reels are lowered, the magnetic
field of the actuator is positioned near the reed switch,
and the contact in the switch closes. The switch has an
electrical connector attached to the carrier frame.

Front Reels Down Switch (Serial Number 230000001 and Above)
On machines with serial numbers 230000001 and
above, the front reels down switch is a normally open
(NO) proximity switch located on the front carrier frame.
The switch closes when the lift arm is in the lowered
position. As the lift arm is lowered, a bracket on the lift
arm comes close to the switch, causing the switch to
close and complete the circuit.
This switch can be tested using the “Input Checks” fea-
ture of the ACE Diagnostic tool.
The switch can also be tested manually.
1. Disconnect the switch wire connector and install
continuity tester or ohm meter between the two switch
leads.
2. With the lift arm in the lowered position the tester
should show continuity. With the lift arm in the raised
position, the tester should show no continuity.
Adjustment
1. Move the lift arm toward the switch (rearward) as far
as it will move.
2. Move switch bracket to lowest position in its adjust-
ment slot.
3. Adjust gap between switch and lift arm flag to .0625”
(1.6 mm).
