Unfolding (Parking, Storage, Service)
To unfold, off field, for parking, storage or servicing,
unfold with the center section fully raised.
1. Hitch to a suitable tractor (page 36).
2. Retract the fold/lift circuit to fully raise the applicator
lift-assist.
3. Raise the tractor 3-point hitch.
4. If lift-assist lock channels are not installed, set
circuits to Neutral. Shut off the tractor. Remove
spacers (page 43). Install lock channels (page 50).
Re-start the tractor.
5. Remove the wing lock pins (page 50).
Refer to Figure 33

7. Extend the fold/lift circuit to unfold the wings.
8. Set all circuits to Neutral.
9. Shut off the tractor.
10. Unless using blocks or stands under wings, fully
extend wing gauge wheels (page 91).
11. Deploy parking stands at desired or maximum
height.
12. Start the tractor. Lower the 3-point hitch until the
applicator rests on the parking stands at front.
13. If wings stop above horizontal, move switch to FIELD
position, and Extend fold/lift to further unfold.
14. Extend until the gauge wheels contact the ground or
the wings stop. Set the fold/lift circuit to Float.
Notes about normal unfold:
• Inner wings unfold first. The outer wings are
constrained by the wing latches (page 50).
• Outer wings unfold last. The wing latches release just
before the inner wings are level.
• Wings do not unfold to below wings-level.
Machine Damage Risk:
Set the switch to UNFOLD. If set to PARK or FIELD, the
wings may unfold to below level and drag inward on the
ground.
