Raise Pre-Folding (from Unfolded)
These steps presume an applicator parked or stored
unfolded, already raised, but on lift-assist locks at rear,
on extended gauge wheels at wing tips, and on parking
stands at hitch.
1. Verify that lock channels are installed on the
lift-assist cylinders (page 50), that wing lock pins are
not in the locking holes (page 50) and that the
hydraulic harness is connected at the hitch
(page 40).
2. Raise the tractor 3-point hitch enough to lift gauge
wheels, coulters, and the parking stand bases off the
ground. Set the hitch circuit to Neutral.
Refer to Figure 25
3.
Set the FOLD / FIELD switch to FIELD. This arrests
fold at field lift.
4. Retract the fold/lift circuit until lift-assist and wing fold
operations each their stops. Set fold/lift circuit to
Neutral. Shut off the tractor engine, leaving the
FOLD / FIELD switch powered-up
a

5. Raise the parking stands (page 42).
a. If the FOLD / FIELD switch is wired directly to the tractor battery, the tractor may be shut off completely. Otherwise leave the ACC
active.

Gradual Crushing Hazard:
Do not rely on hydraulic pressure alone to keep the applicator
raised. Use parking stands (page 42) and locks (page 50)
when working around a raised applicator. The tractor hitch
may settle.
Equipment Damage Risk:
Do not fully fold or fully unfold while lowered. Perform
complete fold and unfold only when fully raised. When
lowered, the wing coulters near the wing pivots may be
damaged by bending or ground dragging.
