Unfolding The Planter
The distance between the tractor and the seed structure
decreases by about 10 feet (3 m) during unfolding.
Planter, tractor, or both will move during this operation.
Crushing, Pinch-Point and Overhead Hazards:
To prevent serious injury or death:
▲ Unfold only on hard level ground. Allow ample room.
▲ Allow no one on or near the planter during unfolding.
▲ Stay clear of the wing sweep arcs. The sweep arcs of the
wings have numerous pinch and crush points in the mecha-
nism. Coulters and row openers are sharp.
▲ Allow no one near planter during unfold. The seed structure
usually moves forward during unfolding.
▲ Do not unfold with planter lowered.
▲ Unfold only with markers resting in transport cradles.
▲ Unfold only if hydraulics are bled free of air and fully
charged with hydraulic oil.
Prepare Hitched Tractor and Planter
Move planter to level ground.
If tractor movement is not desired, put tractor in Park
and/or set parking brakes, or telescoping movement
of planter may cause tractor to move backward.
On the CFM (Clutch Folding Module), set the
following switches to OFF (down):
Prepare Transport Hooks
Refer to Figure 15
The transport hooks
, behind/above wing pivots,
prevent the frame from fully lowering when the planter is
fully folded. To clear the hooks, the frame is fully raised.
Refer to Figure 14
Set CFM Lift/Hitch switch
to “Lift” to enable lift
Set CFM Marker/Fold switch
to “Fold” to enable
fold cylinder hydraulics.
Activate lift hydraulics. Raise planter until lift
hydraulics are fully raised. This raises the wing
above the hooks
Planter Damage Risk:
Be sure planter’s lift hydraulics are fully raised before
unfolding or frame and/or hook damage WILL occur.
