Abstract:
The invention refers to a hydraulic control system for controlling operation of a work attachment of a work machine, comprising a controller configured to output a work attachment control value controlling the operation of the work attachment, an operator input device configured to output a command signal depending on the amount of actuation of the operator input device for setting the work attachment control value, a save input device configured to generate a save command signal upon actuating the save input device and a mode select input device configured to select a first mode and a second mode, wherein the controller is configured to save a constant work attachment control value, wherein the constant work attachment control value is the work attachment control value as set by the command signal upon receiving the save command signal.
