Unfolding the Planter
!
WARNING
To prevent serious injury or death:
▲ Fold only if hydraulics are bled free of air and fully charged
with hydraulic oil.
▲ Stay away from frame sections when they are being raised
or lowered.
▲ Keep away and keep others away when folding or unfolding
planter.
Unfold planter on level ground with tractor in neutral.
1. Switch drive line clutches off.
Refer to Figure 20
2.
Set electronic valve selector switch in tractor to
“FOLD” to activate fold cylinder hydraulics.
3. Activate lift hydraulics. Raise planter until lift hydrau-
lics are fully raised.
!
CAUTION
Be sure planter’s lift hydraulics are fully raised before unfold-
ing or machine damage WILL occur.
Refer to Figure 21
4.
Raise 3-point hitch to release wing hooks.
5. The fold system uses rephasing cylinders. It is nec-
essary to rephase cylinders so wing gauge wheels
run in their fully rotated positions in front of planter.
To rephase fold cylinders:
Move and hold lever in fold direction for 30 seconds.
This causes wings to push against the tongue trans-
port hooks
.
Refer to Figure 22
6.
Reverse fold lever until wings clear transport hooks
by a few feet.
7. Lower 3-point hitch to planting position. See page 13
and page 28 for correct hitch height and depth con-
trol settings.
!
CAUTION
Failure to lower the 3-point before unfolding WILL result in
opener or seed delivery system damage.
8. Unfold planter fully to planting position.
