BRAKE INTERLOCK SWITCH
NOTE:
Use a multimeter to determine when the switch
contacts 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.
1. Engage the parking brake and adjust the brake
switch as required to close the contacts when the
pedal is pressed and to open when the pedal is
released (Figure 2C-10).
Figure 2C-10. Parking Brake Switch
2. Add or remove shims as needed to obtain an air
gap (Figure 2C-11) of 0.09375 to 0.125 in (2 to 3
mm) between the sensing surface of the switch
and brake arm.
Figure 2C-11. Brake Arm Gap
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 an air
gap of 0.09375 to 0.125 in (2 to 3 mm) between
the lift-limit switch and lift arm.
Figure 2C-12. Lift-Limit Switch
NOTE:
Use a multimeter to check for continuity between
the switch wires. Continuity should be available
when the lift arm passes just below 30° from hori-
zontal.
5. Use a multimeter to determine when the switch
contacts are opened or closed.
6. Raise the lift arm manually to 30° above horizon-
tal.
NOTE:
The lift-limit switch sets the point where the switch
turns off the reel drive, not how high the reels rise.
The reels will actually rise to a position slightly
above 30°.
