Hydraulic Hose Hookup
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 28
To distinguish hoses on the same hydraulic circuit,
refer to plastic hose label. The hose under an
extended-cylinder 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 20.
