11. Set hitch height to planting position (“Raising/Low-
ering Tongue” on page 18).
Raising/Lowering Planter
Refer to Figure 20
Planter raising/lowering relies on the four lift cylinders
at the mainframe and wing end gauge wheels.
The planter must be raised for folding and unfolding.
The planter will not lower if transport locks are installed.
See “Lift Cylinder Lock-Up” on page 29.
Note: When unfolded, if one or both markers are extend-
ed, they may drag or shove if left extended during
raise or lower operations. To avoid this, fold mark-
ers prior to raise or lower.
Machine Damage Risk (Hydraulic Hitch Only):
Do not lower planter while folded unless cylinder lock chan-
nels are installed on cylinders. Without lock channels, lower-
ing when folded causes the front center transport wheels to
contact the inside wing row units. Damage WILL occur.
Machine Damage Risk:
Do not lower while any planter folding operations are under-
way or partially complete, with either hitch.
Machine Damage Risk:
Always raise the planter for any reverse/backing operations.
