Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Check all hydraulic lines and fittings before applying pressure.
Relieve pressure before disconnecting hydraulic lines. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Fluid escaping from a very small hole
can be almost invisible. Use 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. If hydraulic fluid is injected into the skin or eyes, seek
immediate medical assistance from a physician familiar with
this type of injury. Within a few hours gangrene can start to
develop. DO NOT DELAY.
Color Coded Hose Handles
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.
Check Drill Level
These items are set and verified at the factory or by your
dealer, but need to be checked prior to first use.

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.
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 “
