Release Wing Locks
Refer to Figure 15
A pair of inverted hooks
on the tongue tube engage
locks on each wing when the planter is folded. This
lock system must be released prior to unfolding.
7. This step is slightly different depending on hitch type .
Release Wing Lock with 3-Point Hitch
a.
Raise the 3-point hitch to disengage the wing
lock. Continue at step 8.
Release Wing Lock with Hydraulic Hitch
Refer to Figure 14
a.
Set CFM Lift/Hitch switch to Hitch.
b. Raise hydraulic tongue to disengage wing lock.
Re-Phase Fold Cylinders
8. The fold system uses re-phasing cylinders. It is nec-
essary 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 15
9.
Reverse fold circuit lever until wings clear transport
hooks
by a few feet.
Lower Tongue
10. Lower 3-point hitch or hydraulic tongue to planting
position. See page 16 and page 126 for correct hitch
height and depth control settings. If hydraulic tongue,
set CFM Lift/Hitch switch
to Lift.
Certain Machine Damage:
Failure to lower the tongue before unfolding WILL result in
opener or seed delivery system damage.
Fully Unfold
Refer to Figure 16
11. Unfold 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
.
Do not plant if this latch is not fully down over the roller.
Frame and opener damage is likely if the planter is operated
with the latch open.
