Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. 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
Refer to Figure 10
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.

To run drill on tractors with open-center hydraulics or on
tractors with fixed-displacement hydraulic pumps, you must
install a Great Plains kit, part number 194-143A. If you are
not familiar with your tractor hydraulics, consult your trac-
tor dealer.
Note: If your tractor has only two remote valves, you must
install a double-selector valve to combine the trans-
port-lift and opener-lift circuits. See “Two Outlet
Hydraulic Kit” on page 91.
