Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Relieve pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Escaping fluid under pressure can have sufficient
pressure to penetrate the skin, causing serious injury. 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.
Color Coded Hose Handles
Refer to Figure 11
Great Plains hydraulic hoses now 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.
1. Connect opener-lift hoses to circuit designated for
hydraulic-motor control.
2. Connect transport-lift hoses to tractor remote valve.
3. Connect fold hoses to tractor remote valve.
4. Connect marker hoses to tractor remote valve.

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 tractor
dealer.
Note: If your tractor has only two remote valves, you
must install a double-selector valve to combine the
transport-lift and opener-lift circuits. See “Two
Outlet Hydraulic Kit” on page 98.
