Abstract: A method and apparatus for controlling movement of a work implement movably connected to a work machine. Movement of the work implement is controlled by manual and automatic control valves that are associated with “manual” and “automatic” modes of operation. The manual and automatic control valves are connected between hydraulic motors for controlling movement of the work implement and a hydraulic fluid supply. Each of the manual and automatic control valves governs hydraulic fluid flow to the hydraulic motors. A pressure sensing device is associated with the manual control valves to detect operator modulation of the manual control valves and thereby alter operation of the automatic control valves in the “automatic” mode on the same side of the implement.
