Hydraulic Hose Hookup
High Pressure Fluid Hazard:
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.
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.
Refer to Figure 12
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.
Current Style Color Coded Hose Handles
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.
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 95.
