2. Add or remove shims as needed to obtain correct
air gap between switch sensing surface and brake
arm. (Figure 2C-11).
• Magnetic Switch - 0.098 to 0.125 in. (2.5 to 3 mm).
• Digital (Orange) Switch - 0.125 to 0.157 in. (3 to 4

LIFT-LIMIT SWITCH
The center reel lift arm is equipped with a proximity
switch. The switch turns off the reels when the center
reel rises above 30° over horizontal.
The switch is mounted on the front axle directly behind
the lift arm. If the reels continue to run when lifted, or
do not run when lowered, inspect the switch. Adjust or
replace the switch as needed (Figure 2C-12).
1. Park the tractor on a flat, level surface.
2. Remove the center reel from the lift arm.
3. Place the ignition switch in the OFF position and
remove the ignition key.
4. Add or remove shims as needed to obtain correct
air gap between switch sensing surface and lift
arm. (Figure 2C-12).
• Magnetic Switch - 0.098 to 0.125 in. (2.5 to 3 mm).
• Digital (Orange) Switch - 0.125 to 0.157 in. (3 to 4
mm).
NOTICE
Use a multimeter to determine when the switch con-
tacts open and close. With the ignition switch in the
ON position, one of the switch wires will have current
(12V) available at all times. The other wire will only
have current available when the parking brake is
depressed.
