Make ADC2350/E Hydraulic Connections
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Relieve pressure before disconnecting hydraulic lines.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Use a piece of paper
or cardboard, NOT BODY PARTS, to check for leaks. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. If an accident occurs, seek immediate
medical attention from a physician familiar with this type of
injury.
Current Style Color Coded Hose Handles
The air cart itself consumes hydraulic power for one or
two circuits, and has a low pressure sump return line.
When the cart leads the drill, the cart also passes
through three circuits necessary for drill operations.
Refer to Figure 16
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.
To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip. Hoses with an
extended-cylinder symbol feed cylinder base ends.
Hoses with a retracted-cylinder symbol feed cylinder rod
ends.
For hydraulic fan and drive motors, connect the hose
under the retracted cylinder symbol to the pressure side
of the motor. Connect the hose under the extended
cylinder symbol to the return side of the motor.
The fan motor further requires hookup of a third line,
which returns hydraulic fluid from the fan motor case.
Make sure all tractor levers are in neutral or float, or
tractor hydraulics are off, before making connections.
Fan Priority
If your tractor has a priority circuit for hydraulic motors,
connect the fan (Black) to this circuit.
ADC2350/E Hydraulic Hookup
The cart fan uses only the Extend/Base side of the Black
circuit, but both sides (plus sump) are passed through to
the trailing drill.
For CTA implements, some tractors require an auxiliary flow
kit to prevent damage to the hydraulic pump. Contact a factory
trained service technician before hooking to cart and CTA
implement.
