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.
