Operating Instructions
Electric Clutch Operation
This unit is equipped with an electric clutch mounted on
each drive. This allows the operator to selectively shut
off one side of the drill at a time to accommodate point
row seeding.
The control box is mounted in the tractor cab and has
two on/off toggle switches with red indicator lamps.
This unit is also equipped with an electric clutch switch
that automatically shuts off seeding to both sides
whenever the unit is raised out of the ground.

Opener Operation
Do not back up with openers in the ground. To do so will cause
severe damage and opener plugging.
For information on opener adjustments, refer to “Opener
Adjustments,” page xxxvi. For more information on
troubleshooting opener problems, see “Troubleshooting”,
Marker Operation
Optional marker attachments are available from your
Great Plains dealer. Before operating markers, make
sure hydraulics are properly bled as described under
“Marker Adjustments”, page xliv.
Dual markers equipped with a sequence valve are
powered off the same hydraulic circuit. Starting with both
markers folded, the folding sequence is:
1. Activate lever - Right unfolds; left stays folded.
2. Reverse lever - Right folds; left stays folded.
3. Activate lever - Left unfolds; right stays folded.
4. Reverse lever - Left folds up; right stays folded.
5. Sequence repeats.
You can adjust marker folding speed. Refer to “Marker
Adjustments”, page xliv, and adjust folding speed to a
safe rate. Folding markers at high speed can damage
markers.
