Unfolding
!
DANGER!
Crushing and electrocution hazards. Keep others away during
unfolding operations. Do not walk under wings when unfolding
planter. See Figure 2-7 on page 17 before attempting to unfold
planter. Keep clear of overhead power lines when unfolding
planter or markers.
Unfolding is best achieved on level ground with the tractor
transmission in neutral. Be aware of the clearance re-
quired to unfold the planter.
NOTE: If unfolding planter with hoppers fully loaded, you
will need a tractor with at least 1900 psi hydraulic pres-
sure.
1. Make sure hydraulic selector valve on tongue is in
road position. See Figure 2-8 on page 18.
2. Begin to unfold planter.
3. When wings have cleared the outside hopper on the
center section, switch rear selector valve to field posi-
tion. See Figure 2-12.

4. Raise planter. This will lower the wing gauge wheels.
5. Continue unfolding planter.
IMPORTANT: If the planter has set in the folded po-
sition for awhile, be sure the wing gauge wheels are
fully retracted before beginning to unfold planter. If
wheels are not retracted hopper damage will occur
when unfolding planter. Retract wheels by lowering
planter on transport locks.
IMPORTANT: Make sure wings have cleared outside
hopper on center section before raising the planter. If
raised too soon, gauge wheels will cause hopper
damage.
6. When wing gauge wheels contact the ground, pull
planter ahead a few feet while continuing to lower
planter. This will level wings.
7. Remove the cylinder locks by removing the bent pins
and pivoting the locks off the cylinders. Replace the
bent pin to keep the locks off the cylinder.
8. Position arm wing lock pins as shown, see Figure 2-
13
. If wings are not level, it may be necessary to pull
forward a few feet to lock wing lock pins.

end of the drive shaft. Slide drive shaft together and
reinstall keeper pin.
10. Before operating planter be sure to place tongue hy-
draulic selector valve on tongue in field position. See
Figure 2-14.
