Important Safety Information
Important Safety Information
For your safety and to develop a better understanding of
your equipment, thoroughly read the Operator’s Sections
of this manual before operation.
Safety Notations
The SAFETY ALERT SYMBOL indicates that there is a
potential hazard to personal safety involved and extra
safety precautions must be taken. When you see this symbol, be alert and carefully read the message that follows it.
In addition to design and configuration of equipment; hazard control and accident prevention are dependent upon
the awareness, concern, prudence and proper training of
personnel involved in the operation, transport, maintenance and storage of equipment.
Watch for the following Safety Notations throughout
your Operator’s Manual:
!
DANGER!
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury. This signal word
is limited to the most extreme situations.
WARNING!
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION!
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used
to alert against unsafe practices
Safety Rules
These rules and instructions
must be reviewed at least annually
by all operators!
Most accidents are the result of negligence and carelessness, caused by failure of the operator to follow safety precautions. Even though your implement is designed with
many built-in safety features, the following precautions are
mandatory to prevent such accidents.
Make sure everyone that uses this machine has read the
Operator’s Manual and understands how to operate it
safely.
This Operator’s Manual is considered a part of the imple-
!
ment and should remain so when loaned or sold.
Prior To Operation
1. Do not stand between tractor and implement during hitching.
2. Do not stand between cart and implement during hitching.
3. Do not operate without safety chain properly attached to
tractor.
4. Make sure hydraulic lines are attached to the correct ports.
5. Handle and apply chemically treated seeds according to
manufacturer's recommendations.
CAUTION!
Some illustrations in this manual may show shields or cover
panels removed for clarity. Never operate unit without all
shields and cover panels in place.
During Operation
1. Do not allow anyone to operate this machine who has not
been properly trained in its safe operation.
2. Do not let children operate the implement.
3. Never dismount from a moving tractor
4. Put tractor in park turn off engine and remove key when
making any adjustments to the implement
5. Do not leave the tractor or the implement unattended with
the engine running.
6. Never allow passengers.
7. Travel slowly over rough terrain and be alert to holes and
gullies.
8. Loose fitting clothing should not be worn as it may catch in
moving parts.
9. If a hydraulic leak develops, correct it immediately. Escaping hydraulic oil can have extremely high pressure. A
stream of high pressure oil may easily penetrate the skin as
with modern needle-less vaccination equipment - but with
the exception that hydraulic fluid may cause blood poisoning. It is imperative that the connections are tight and that
all lines and pipes are in good condition. If an injury is
caused by the escaping hydraulic fluid, seea doctor at once!
Use a piece of cardboard or wood to detect leaks of hydraulic oil under pressure. Be sure to relieve all hydraulic pressure before disconnecting any lines or pipes between the
implement and the tractor hydraulic system.
10. Keep all guards and shields in place.
11. Do not turn tractor too tight; implement may ride up on
wheels causing machine and bodily damage.
DANGER!
Contact with overhead power lines can cause severe electrical
burns or death from electrocution. Make sure there is enough
clearance between all air drill components and overhead power
lines. Do not use loading auger near power lines. Do not climb
on walkboard near power lines.

Section 2 Operating Instructions
Section 2 Operating Instructions
General Description
The seed metering mechanism of this drill is powered by
the cart tire and is driven at a rate proportional to distance
driven. This ensures that the rate applied in pounds per
acre remains constant as ground speed is varied. The
pounds per acre rate is adjustable and can be set using
the gearbox, speed change sprocket and hi-low gears on
the meter. The metering device is driven through an electro-magnetic clutch which will not engage unless the fan
motor is running at high speed and the implement is lowered past an adjustable height switch. This prevents the
primary seed hoses from being plugged by seed being
metered into them without the fan running and also allows
the seed to be shut off automatically when the drill is lifted
on head lands. The seed bins are sealed and held at the
same pressure as the meter chambers so that metering is
controlled mechanically and not by air flow fluctuations.
The metered seed is carried by air through the primary
hoses to the distribution towers on the implement. These
towers then divide the air and seed into individual rows
and it is carried to the openers in the secondary hoses.
Prestart Checklist
• Lubricate the drill as indicated in the Lubrication portion
of the “Maintenance and Lubrication” section starting

Attaching the Drill to the Tractor
NOTE: The tractor must be of adequate size to pull
the drill. When determining size of tractor keep in
mind the soil, terrain, row spacing and type of opener.
Recommended Minimum Tractor Size
For standard openers:
34’ Implement - 180 HP
45’ Implement - 240 HP
For double shoot:
34’ Implement - 225 HP
45’ Implement - 300 HP
CAUTION!
The tractor, or towing vehicle, must have adequate unladen
mass to control the drill when towing. Do not exceed 20 miles
per hour.
Minimum vehicle weight - loaded drill:
up to 20 mph maximum - 45,000 lbs.
up to 10 mph maximum - 22,000 lbs.
Minimum vehicle weight - empty drill:
up to 20 mph maximum - 28,000 lbs.
up to 10 mph maximum - 14,000 lbs.
DANGER!
You may be severely injured or killed by being crushed between
the tractor and the drill. Do not stand or place any part of your
body between the tractor and drill while hooking up the drill.
Back the tractor drawbar up to the drill until the holes in the
drill tongue and the tractor drawbar are in line. Use the jack
to make height adjustments. Be sure that the hitch is properly adjusted for level operation, refer to Hitch, Safety Chain,
and Jack in the “Cart Assembly and Setup” section on
page 9. Install the drawbar pin and the pin retainer clip. Remove the jack and store on the stob on the tongue center rail
in horizontal position. Attach the safety chain on the drill to
an anchor on the tractor capable of pulling the unit.
NOTE: The tractor must have at least 3 sets of hydraulic outlets and be capable of supplying 15-30 gallons per minute at 2000 psi.
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, and
wear heavy gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with this type
of injury. Foreign fluids in the tissue must be surgically removed
within a few hours or gangrene will result.
NOTE: The SAE o-ring and JIC 37˚ flare type hose
connections do not require sealant for reconnecting.
They do not require high torque for a good seal.
IMPORTANT: When using sealant on pipe threads the friction between the threads is reduced; therefore, be certain
not to overtighten or damage to the components may occur.

connected. See your Great Plains dealer if you require
new quick coupler ends for your hoses.
Make sure that each pair of hoses connected to your tractor outlets are from the same circuit (lift, fold, or fan)
Hook up the electric clutch cable to the clutch harness on
the tractor.
If the tractor does not have a clutch harness installed it
must be installed now. Attach the switch box solidly to the
tractor in a convenient location not exposed to rain. Attach
the power leads to a 12 volt D.C. power supply, polarity is
not critical. Be sure that the wire is safely routed where it
will not be pinched or rubbed through. Before drilling any
holes always check on the back side to make sure no hidden components will be damaged by the drill.
Safety Lights
The light package your drill comes equipped with requires
that your tractor be wired for the standard 7-pin electrical connector which will work with the tractor’s flashers and signals.
All that should be necessary is to plug in the connector.
If your tractor is not equipped with this connector please
consult your dealer for installation to tractormanufacturers
specifications.
Attaching 2250 Air Drill Cart to
Great Plains 34’ or 45’ Implement
Follow instructions in the implement manual to connect
the implement hitch to the cart. Be sure all pin retainers
are in place and all fasteners are tight. When all hitch connections have been made the 2 1/2” primary hoses can be
connected. Attach the hoses left to right on the meter in
the same order as towers are installed on implement.
Leave enough slack so that the implement may be fully
raised, lowered, folded and unfolded without binding.
When connecting double shoot drills be sure to connect all
