Great Plains Mfg., Inc.
Shaft Monitor Operation
To operate the optional shaft monitors, turn the shaft mon-
itor switch on the control console to the on position. If ei-
ther seed-cup shaft stops for 20 seconds, an alarm will
sound. A light on the control console will designate the
failed shaft.
The 20-second delay is to prevent nuisance alarms when
turning at the end of the field. If the shaft alarm sounds, re-
member you have traveled for 20 seconds without seed-
ing.
Electric Clutch Operation
A mechanical jaw clutch on each gauge-wheel-arm pivot
turns seeding on and off as the drill is raised and lowered
in the field. Optional electric clutches allow you to turn
seeding off while the drill is lowered. A clutch for each
drive shaft allows you to control each drill box indepen-
dently. The clutches are controlled through the in-cab con-
trol console.
For regular field operation, turn the electric-clutch switch-
es on the control console to the on position. This will acti-
vate the magnet on each clutch and allow the clutch shafts
to rotate. The mechanical jaw clutches will continue to
control seeding.
To shut off seeding in one or both boxes while the drill is
lowered, turn one or both switches to the off position.
Transporting
!
CAUTION!
This implement should never be towed faster than 20 mph.
Before transporting, check and practice the following
items.
Fold Drill. Transport the drill in folded position with trans-
port-lock cylinders extended. Refer to Folding the Drill,
page 16.
Loaded Boxes. This drill can be transported with boxes
loaded with grain, but only with extreme caution. The ad-
ditional weight reduces maneuverability and increases
stopping distance.
Stopping Distance. Keep the weight of this drill in mind.
Allow sufficient stopping distance at all times. Reduce
speed prior to making any turns or other maneuvers. In-
crease stopping distance if transporting with loaded box-
es.
Bystanders. Check that no one is in the way before mov-
ing. Do not allow anyone to ride on the drill.
Tractor Requirements. Check that the towing vehicle is
large enough to control the drill on the road. Refer to Trac-
tor Requirements, page 15.
Clearance. Know drill dimensions in transport position
and follow a route that provides adequate clearance from
all obstructions. Refer to “Specifications and Capaci-
ties,” page 43.
Tires. Check that all tires are properly inflated as listed on
Tire Inflation Chart, “Appendix,” page 44.
Road Rules. Comply with all federal, state and local laws
when transporting on public roads.
Warning Lights. Always use warning lights when trans-
porting the drill.
Watch Traffic. Be prepared for sudden maneuvers from
following vehicles.
Markers. Always transport optional markers folded flat.
Make sure the second marker section rests securely on
the transport carrier.
Parking
Perform the following steps when parking the drill. Refer to
Storage, “Maintenance and Lubrication,” page 34, for in-
formation on long-term storage preparation.
1. Raise, lock and fold the drill in the transport position.
Refer to Folding the Drill, page 16.
2. Park the drill on a level, solid area.
3. Securely block the tires to prevent rolling.
4. Remove the jack from its storage stob. Pin it on the
stob on the left side of the tongue. If the ground is soft,
place a board or plate under the jack.
5. Extend the jack until tongue weight is off the drawbar.
6. Unplug the hydraulic lines from the tractor. Do not al-
low hose ends to rest on the ground.
7. Unplug the control-console cable from the tractor. Un-
plug the drill light cable from the tractor.
8. Remove hitch pin and safety chain from tractor draw-
bar.
