Unfolding the YP4425A Planter
The distance between the tractor and the seed structure
decreases by 12 feet (3.7 m) during unfolding. Planter,
tractor, or both will move during this operation.
Crushing, Pinch-Point and Overhead Hazards - To prevent
serious injury or death:
▲ Fold only on hard level ground. Allow ample room.
▲ If it is desired that the tractor not move, make sure tractor is
in Park and/or has parking brakes set, otherwise the
telescoping movement of the planter is likely to result in
tractor movement.
▲ 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
mechanism. 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.
