Re-phasing Fold System
In typical use during a single planting operation, it is nor-
mal for the fold cylinders to get slightly out of phase,
resulting in uneven folding and unfolding of the
YP3025A.
Every few planting days, re-phase the cylinders with this
procedure:
1. Raise, unfold and fold the planter completely, and
hold the fold hydraulic lever or switch in Extend for
several seconds after the planter reaches full folding,
or until all cylinders are fully extended.
2. When all cylinders are fully extended, reverse
(Retract) the control to unfold and return to planting.
