and jack has been removed the hydraulic hoses may be
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 trac-
tor 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 hid-
den 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 con-
nector 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 tractor manufacturers
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 con-
nections 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
fertilizer meter outlets to the fertilizer opener towers and all
seed meter outlets to seed opener towers, see Figure 2-1.
If any hoses appear to be rubbing on sharp edges or are in
danger of getting pinched use cable ties to secure in a safe
location. Secure hoses to metering box outlet tubes using
2 1/2” air hose band clamps and tighten securely. Be sure
that placement of outer clamps does not interfere with op-
eration of metering box calibration door latch clamps, refer
to Figure 2-2.
Hydraulic Hose Hook-up
!
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.
Refer to Figure 2-3:
Connect the 2 hoses for the fold circuit to the quick cou-
plers nearest to the outside of the cart. If the drill is
equipped with an auger the diversion valve should be in
the fold circuit.
Connect the 2 hoses for the lift circuit to the quick couplers
nearest to the center of the cart.
