Unfolding and Folding 2013+ 5-Section
2-Point
Unfolding 5S 2013+ (At Field)
These instructions presume the applicator has just
completed transport, is raised, and transport locks are
installed. It is being unfolded for field use.
1. Remove the wing lock pins (page 46).
Refer to Figure 45
2.
Set the FOLD / FIELD switch to
FOLD / UNFOLD.
3. Extend the fold/lift circuit to unfold the wings
4. Retract the fold/lift circuit slightly to raise the
lift-assist off the lock channels.
5. Set all circuits to Neutral. Shut off the tractor.
6. Remove the lift-assist lock channels (page 44).
Install the spacers (page 38).
7. If wing gauge wheels were extended, crank them to
field height (page 86).
8. Lower the hitch to field height.
Notes about normal unfold:
• Inner wings unfold first. The outer wings are
constrained by the wing latches (page 46).
• 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.
