4-11 OPENERS – HYDRAULIC OPERATION
4-11.1 The grain drill openers are raised and
lowered through a hydraulic lift system. Fully
retract all cylinders to raise the openers.

4-11.2 Raise the openers when transporting.
4-11.3 During planting operation, always raise
the openers before turning. Failure to raise
the openers while turning can generate enor-
mous side loading which could damage the
openers.
4-11.4 Never back up the Grain Drill with the
openers in the ground. This can plug and
possibly damage the openers.
