  • System for controlling movement of a work machine arm
    Patent number: 6915599
    Abstract: A method of controlling the movement of a work machine arm having a series of hydraulic cylinders operatively engaged with the work machine arm includes receiving a signal from an input device to change the position of the work machine arm and determining an extension amount of one or more of the series of hydraulic cylinders. The extension amount of one or more of the series of hydraulic cylinders is changed to effect the change in the position of the work machine arm. The changes in the extension amount of the one or more of the series of hydraulic cylinders are ordered based on a pre-selected priority of movement.
