OPERATION AND MAINTENANCE
Hydraulic Row Markers (Option)
1.
The Seeder Hitch may be equipped with optional
hydraulic row markers. This will require a fourth
tractor remote to operate the markers.
DANGER
DANGER
2.
To operate the markers, unfold the seeder so that it is
in planting position. Never attempt to fold/unfold the
markers with the seeder in folded or transport
position.
3.
With both markers in the raised position, slowly
engage the marker hydraulics. One marker will
extend. Reversing the hydraulic lever will raise that
marker.
4.
Slowly engage the marker hydraulics again and the
opposite marker will extend.
5.
Reverse the marker hydraulics again and that marker
will rise.
6.
The marker unfold/fold process will then repeat itself.
CAUTION
7.
Insure that the marker hydraulic system is full of oil
before attempting to fold or unfold the markers. If a
hydraulic component is removed, repaired, or
replaced the system must be purged of air before
folding/unfolding the markers. To purge the system of
air, unpin the rod end of both marker cylinders. Align
or prop the cylinders into position so that the rod will
not interfere with anything during its travel. Slowly
engage the tractor hydraulics fully extending and
retracting both marker cylinders. Repeat several
times until the action of both cylinders is positive and
immediately responsive. Do not loosen or crack any
fittings. Reconnect the rod end of both cylinders.
To prevent injury or death, stay clear of markers
while folding/unfolding. Hydraulic failure can
allow markers to raise or fall suddenly.
To prevent injury or death from electrocution:
stay away from power lines while transporting,
folding, or unfolding markers. Electrocution can
occur without direct contact of power lines.
Marker blades are very sharp, use gloves when
working around marker blades.
