Abstract
One embodiment is a work machine including an actuator coupled with a chassis, a suspension coupled with the actuator, and a tool mount coupled with the suspension. A grading tool assembly is coupled with the tool mount. A wireless receiver is coupled with the suspension. An electronic controller in operative communication with the receiver and the actuator is structured to adjust the actuator in response to a signal received by the receiver effective to simultaneously adjust the position of the receiver and the force applied to the suspension. A grading indicator is coupled with the suspension and provides a visually perceptible indication of a current state of grading relative to a desired state of grading.
