Row Unit Operation
IMPORTANT: Do not back up with row units in
the ground. To do so will cause severe dam-
age and plugging.
For information on row unit adjustments, refer to
page 26. For more information on troubleshooting
row unit problems, see “Troubleshooting”, page
45.
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. Starting
with both markers folded, the folding sequence is:
1. Activate lever - Right unfolds; left stays
folded.
2. Reverse lever - Right folds up; 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 38, and adjust folding
speed to a safe rate. Folding markers at high
speed can damage markers.
