Unfolding, Continued ...
Machine Damage Risk:
Raise hitch before unfolding. If hitch is not raised, wing locks
will remain in transport hooks. Wings will not unfold, and
machine damage is possible.
8. Set CFM Marker/Fold switch to Fold. LED above
switch blinks continuously.
9. Activate (normally Retract) tractor hydraulic circuit to
unfold wings.
10. Operation is complete when the tongue lock
engages.
Machine Damage Risk:
Do not operate planter when unfolded unless tongue lock is
engaged. When unlocked, the pull bar system experiences
excess loads. The openers may be damaged by not tracking
straight forward.
11. When fully unfolded, set Marker/Fold hydraulic
circuit to Neutral.
12. For imminent lowered operations, remove lift
cylinder locks (see “
page 30).
13. Set hitch height to planting position
Machine Damage Risk:
Unfold and fold slowly. Adjust hydraulic flow to take a
minimum of 60 seconds to unfold or fold. Wings are massive,
and damage can occur if they reach the end of travel at high
speed. At lower speeds you also have time to check for hose
pinching or kinking, as well as react to anything unexpected in
the sweep arc.
