Hydraulic Hose Hookup
!
WARNING
Escaping fluid under pressure can 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 suspected leaks. Wear protective gloves and
safety glasses or goggles when working with hydraulic
systems. If an accident occurs, see a doctor immediate-
ly. Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
IMPORTANT: To run drill in the field on trac-
tors with open-center hydraulics or on trac-
tors with fixed-displacement hydraulic
pumps, you must install a Great Plains kit,
part number 194-143A. You can set up drill
and bleed hydraulics with either an open- or
closed-center system.
Great Plains hydraulic hoses are color coded 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 plastic hose holder. Hose under extended-
cylinder symbol feeds cylinder base ends. Hose
under retracted-cylinder symbol feeds cylinder
rod ends.
1. Connect opener-lift hoses to circuit designat-
ed 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 com-
bine the transport-lift and opener-lift circuits. Re-
fer to Two Outlet Hydraulic Kit, Great Plains Part
Number 194-122A, in the operator’s manual.
