Older Color Hose Ties
On older drillsm 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 “
