A single control lever is coupled through linkage to effect individual movement of a plurality of valve spools in a hydraulic system and is supported for movement in predetermined paths to effect operation of the controls for the hydraulic system. Movement of the control lever effects operation of the hydraulic system in response to movement of the lever in a predetermined path.
