Marker Operation
Optional marker attachments are available from
your Great Plains dealer. Before operating mark-
ers, make sure hydraulics are properly bled as
described under “Marker Adjustments”, page 38.
Dual markers equipped with a sequence valve are
powered off the same hydraulic circuit. The mark-
ers cycle in the following sequence:
1. right up, left up
2. right down, left up
3. right up, left up
4. right up, left down
You can adjust marker folding speed. Refer to
“Marker Adjustments”, page 38, and adjust folding
speed to a safe rate. Folding markers at high
speed can damage markers.
Transporting
Loss of Control Hazard:
Towing the drill at high speeds or with a vehicle that is
not heavy enough could lead to loss of vehicle control.
Loss of vehicle control could lead to serious road ac-
cidents, injury and death. To reduce the hazard, do not
exceed 20 mph. Check that your tractor has enough
ballast to handle the weight of the drill. Refer to your
tractor operator’s manual for ballast requirements.
Loss of Control Hazard:
Failure of hydraulic cylinders during transport will
cause drill to drop suddenly, which could lead to seri-
ous road accidents, injury or death. To prevent an ac-
cident, always install cylinder locks before
transporting drill.
Before transporting the drill, follow and check
these items:
Lock Cylinders. Cylinder locks (1) are located on
both hydraulic cylinders. With drill fully raised
swing lock up over rod of cylinder and snap into
place, see Figure 10.
NOTE: The cylinder locks can be engaged or dis-
engaged only after the drill is fully raised.
