Openers - Hydraulic Operation - Landoll 5530 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.
Do not operate the opener hydraulics in the "float"
position.
2. The 40' Grain Drill uses a rephasing hydraulic lift
system for the openers. When lowering the openers,
fully extend the opener cylinder and hold briefly in the
extended position. This allows oil to rephase, or flow
through the hydraulic cylinders thus keeping all
cylinders working in unison.
4-12
3. If the opener bars are not operating at the same
heights, fully extend the opener cylinders and hold
for several seconds until the opener bars are even
and raise and lower in unison.
4. Raise the openers when transporting.
5. 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.
6. Never back up the Grain Drill with the openers in the
ground. This can plug and possibly damage the
openers.
