Field Fold Stop Adjustment
This applies to 2013+ 2-Point 5-Section applicators only.
Refer to Figure 58
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 angled 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
adjustment to compensate for hydraulic problems.
2. Move the applicator to a level surface. Raise and fold
(page 49). Install lift-assist lock channels (page 49)
and parking stands (page 31).
3. Set the FOLD / FIELD switch to FOLD. Extend the
fold/lift circuit to unfold until the inner wings stop.
4. Set the FOLD / FIELD switch to FIELD. Retract the
fold/lift circuit until the wings stop at “gull wing” (field
lift, page 49). Set the circuit to Neutral. Shut off the
tractor.
5. Check the sensor-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 incorrect, correct it, at the current sensor
height. Fold and unfold to see if further adjustment is
required.
6. To adjust the sensor, loosen the bolts securing the
sensor
to the bracket. Do not adjust the
actuator position.
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.
