Unfolding The Planter
The distance between the tractor and the seed structure
decreases by about 10 ft (3m) 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.
▲ Do not allow anyone to be 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. The seed structure usually
moves forward during unfolding.
▲ Do not unfold with planter lowered, or machine damage
will result.
▲ 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
1. Move planter to level ground.
2. 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.
3. On the CFM (Clutch Folding Module), set the follow-
ing switches to OFF (down):
MASTER switch
and Fert.Pump .
Prepare Transport Hooks
The transport hooks, which prevent unfolding during
transport, open automatically only when the planter is
fully raised.
Refer to Figure 12
4.
Set CFM Lift/Hitch switch to “Lift” to enable lift cyl-
inder hydraulics.
5. Set CFM Marker/Fold switch to “Fold” to enable
fold cylinder hydraulics.
6. Activate lift hydraulics. Raise planter until lift hydrau-
lics are fully raised. This prepares the transport
hooks to disengage during unfolding.
