Field Fold Stop
Adjustment
During field fold (FOLD / FIELD switch in FIELD), the
inner wing sections are intended to stop 5 to 10°
above wings-level relative to the center section
. The
stopping point is controlled by an proximity sensor
at
each center/wing hinge. If a wing does not stop in this
range, adjust the proximity sensor.
1. Verify that the misalignment is not caused by air in
the hydraulic system. Do not use the proximity
sensor adjustment to compensate for hydraulic
problems.
2. Move the applicator to a solid, level surface. Raise
and fold (page 55). Install lift-assist lock
channels (page 47) and parking stands (page 40).
3. Set the FOLD / FIELD sensor to FOLD. Extend the
fold/lift circuit to unfold until the inner wings stop.
4. Set the FOLD / FIELD sensor to FIELD.Retract the
fold/lift circuit until the wings stop at “gull wing” (field
lift, page 50). Set the circuit to Neutral. Shut off the
tractor.
5. Check the sensor to actuator (
-
) gap at the
affected wing pivot. With the actuator near the
marked region on the sensor, the gap must be
1
/
8
to
1
/
4
inch (3.2 to 6.3 mm)
If the gap is not correct, correct the gap at the current
sensor height.
6. To adjust the sensor, loosen the bolts that fasten the
sensor
to the bracket.
•
To lower the angle at which the wing stops, raise the
sensor.
•
To raise the angle at which the wing stops, lower the
sensor.
7. Secure the bolts. Fold and unfold to test.
