Release Wing Locks
Refer to Figure 13
A pair of inverted hooks
on the tongue tube engage
locks on each wing when the planter is folded.
Prior to unfolding, this lock system must be released by
raising the tongue. Raise the 3-point hitch to disengage
the wing lock.
Re-Phase Fold Cylinders
5. The fold system uses re-phasing cylinders. It is
necessary to re-phase cylinders so wing gauge
wheels run in their fully rotated positions in front of
planter. To re-phase fold cylinders:
Move and hold lever for Marker/Fold in Fold direction
(typically Extend) for 30 seconds. This causes wings
to push against the tongue transport hooks
.
Partially Unfold
Refer to Figure 13
6.
Reverse fold circuit lever until wings clear transport
hooks
by a few feet.
Lower Tongue
7. Lower 3-point hitch or hydraulic tongue to planting
position. See page 19 and page 123 for correct hitch
height and depth control settings.
Fully Unfold
Refer to Figure 14
8.
Unfold the planter fully to planting position. Unfolding
is complete when the large roller bushing on top of
the tongue is engaged by the tongue safety latch
.
Planter Damage Risk:
Do not plant if the tongue latch is not fully down over the
roller. Frame and opener damage is likely if the planter is
operated with the latch open.
