Openers - Hydraulic Operation - Landoll 5531 Operator's Manual

OPERATION AND MAINTENANCE
Openers – Hydraulic Operation
1. The Grain Drill openers are raised and lowered
through a hydraulic lift system. Fully retract all
cylinders to raise the openers. Likewise fully extend
all cylinders to lower the openers. The cylinders must
be fully extended to insure consistent planting depth
and engage seed drive clutches. Do not operate the
opener hydraulics in the "float" position.

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