Abstract
Earthmoving machines and earthmoving implements are difficult to operate to achieve maximum implement power and to control the implement under changing working conditions. The instant apparatus is designed to maximize implement power by automatically sensing and responding to variables related to implement power and to control the implement by automatically sensing and responding to the longitudinal angular velocity of the machine. The apparatus includes a mechanism for moving the implement in response to sensed variables related to implement power, a transducer for sensing the longitudinal angular velocity of the machine, and a control for modifying the implement position in response to the sensed angular velocity of the machine.
