ADC2350/E Older Style Hoses with Color Ties
Only trained personnel should work on system hydraulics!
Great Plains hydraulic hoses are color coded to help you
hookup hoses to your tractor or drill outlets. Hose
connections are also passed through to a rear panel
when the air cart leads the drill. Hoses that go to the
same remote valve are marked with the same color tie.
Refer to Figure 17
To distinguish hoses on the same hydraulic circuit, refer
to plastic hose label. The hose under an
extended-cylinder symbol feeds a cylinder base end. The
hose under a retracted-cylinder symbol feeds a cylinder
rod end.
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 (Yellow) to this circuit.
Sump First and Last
Seals in the hydraulic fan motor can be damaged if the
return line is pressurized. Always connect the SUMP
hose first and disconnect it last. The sump hose has a
larger (1.06 inch) quick-connect coupling.
ADC2350/E Hydraulic Hookup
The cart fan uses only the Extend/Base side of the
Yellow circuit, but both sides (plus sump) are passed
through to the trailing drill.

The hose & large connector labeled sump refers to high
volume hydraulic motor return and should always be
connected to the port on the tractor capable of handling high
volume low pressure return oil. DO NOT connect this line to
low volume case drain lines or low volume sump lines on the
tractor. See tractor manufacturer’s recommendations for high
volume hydraulic motor return.
