Hydraulic Hose Hookup
!
WARNING
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,
see a doctor immediately. Any fluid injected into the skin must
be surgically removed within a few hours or gangrene will
result.
Refer to Figure 22
To distinguish hoses on the same hydraulic circuit, refer
to plastic hose label. The hose under an extended-cylin-
der symbol feeds a cylinder base end. The hose under a
retracted-cylinder symbol feeds a cylinder rod end.
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.
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.
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 Kit” on page 14.
Hydraulic Operations
Consult the Operator’s Manual for unfolding and lowering
instructions. Pay strict attention to the step ordering.
IMPORTANT !
Both Opener and Transport Lift circuits must be raised
and locked up before folding, or implement damage will
result.
IMPORTANT !
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.
