Abstract: A blade positioning system for a work machine. The system may have a blade control which has a blade position sensor, and the blade control may adjust a blade of the work machine to a fixed position relative to a wheel. The system may also have a steering control that has a wheel position sensor, and the steering control may steer the work machine. The controller may monitor the blade position sensor and the wheel position sensor to determine a present position of the blade and the wheel prior to the repositioning of the wheel, and adjust the blade position as the wheel is repositioned to maintain the fixed position of the blade relative to the wheel.

Abstract: A system for extracting a motor grader from a location with reduced traction includes the motor grader having articulated front and rear frames supported on front and rear wheels, respectively, and a blade extending from the frame toward the surface underlying the grader. A plurality of blade articulation structures are adapted to articulate the blade relative to the frame. A plurality of sensors are provided and a steering mechanism, power source and control system having a controller. The controller is configured to receive the plurality of signals and perform an extraction procedure to reposition the motor grader. The extraction procedure includes automatic execution of a sequence of operations including a plurality of modification of an articulation angle of the front and rear frames, a steering angle, a position of the blade, a disposition of the blade, propulsion of one or more of the wheels, and direction of propulsion.
