Abstract
An apparatus for controlling the torque associated with a power train of a machine having a work implement is disclosed. A plurality of position sensors sense the position associated with the work implement and responsively produce respective position signals. A controller modifies the desired engine speed in response to the angular position of the work implement and regulates the speed of the engine at the modified desired engine speed to control the power train torque.
