Unfolding
Unfold the planter for adjustments, field operations,
maintenance, parking and storage.
1.
Unless the planter was folded, with the currently
hitched tractor, only a short time ago, check for
evidence of oil leaks. Check the ground at hitch
connections, hose fittings and under cylinders.

Bystanders could be crushed under the wings or caught in the
wing fold mechanisms. To avoid serious injury or death, keep
all persons well away during planter unfold.
2.
Be aware of vertical and horizontal clearances
needed to unfold the planter.
3.
Put tractor in Park with parking brake engaged.
4.
Verify that the wing lock pins are not installed in the
lower lock holes (page 22).
5.

that the rear of the center row units are off the
ground.
