Re-phasing Lift System
Over a period of normal use the cylinders may get out of
phase. This will cause some planter sections to run
higher than others. If this is the case, it will be necessary
to re-phase lift cylinders.
Note: Lift cylinders can only be re-phased when planter is
unfolded.
To re-phase cylinders:
1. Raise the implement completely and hold the
hydraulic remote lever on for several seconds until all
cylinders are fully extended. Do this every 8 to
10 times you raise planter out of ground.
2. When all cylinders are fully extended, momentarily
reverse hydraulic remote lever to retract system
1 ⁄
2
inch to maintain levelness.
Folding the Planter
The planter must be raised for folding. The tongue is
raised and lowered during the sequence.
The distance between the tractor and the seed structure
increases by about 10 feet (3 m) during folding. Planter,
tractor, or both will move during this operation.
Pinch Point and Crushing Hazard:
To prevent serious injury or death:
▲ Fold only with planter raised and lock channels installed.
▲ Fold only if hydraulics are bled free of air and fully charged
with hydraulic oil.
▲ Stay away from frame sections when they are being raised
or lowered.
▲ Keep away and keep others away when folding or unfolding
planter.
▲ Fold markers onto cradles before folding planter.
