Abstract: A computer-implemented method for automatically adjusting a moldboard of a motor grader can include receiving one or more identifiers corresponding to a configuration of the motor grader, and determining, based on the received identifier(s), a first orientation of the moldboard. If the first orientation is not within an operating threshold, the method can further include selecting, based on the one or more identifiers, at least one of a plurality of actuators of the motor grader; and actuating the selected actuator(s) to move the moldboard from the first orientation to a second orientation within the operating threshold.

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.

Abstract: A technique is directed to methods and systems of an implement lock-out on lever-controlled machines. A lock-out system can monitor the position of an implement and lock-out the implement control(s) when the implement is within a threshold distance to parts of the machine. The lock-out system can generate an implement lock-out to slow, stop, or reduce the force of a hydraulic valve(s) controlling the implement. The lock-out system can use inputs such as electronic fence blade position system data, articulation angles, wheel lean angles, steering angles, ripper positions, mode selection or similar data to determine to generate the implement lock-out. The lock-out system can generate the implement lock-out by a flow supply shutoff to the implement while maintaining pressure to the steering valve. The lock-out system can send visual or audible notifications to alert the operator of the implement's proximity to the machine or of an implement lock-out.

Abstract: The present disclosure is directed to systems and methods for operating a grading machine. The method includes (i) receiving information regarding material on a surface, and the grading machine is configured to travel on the surface and move the material on the surface; (ii) determining a set of parameters for operating the grading machine, and the set of parameters include an articulation angle of the grading machine and a moldboard angle of a moldboard of the grading machine; and (iii) positioning a snow wing and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard.

Abstract: In a motor grader, a total drawbar position may be determined based on signals from various sensors on a drawbar-circle-moldboard (DCM) assembly. The sensors can include rotational sensors for one or both lift arm angles, and one or both yoke primary angles in combination with sensors detecting lengths of the lift cylinders. The sensor information may be used to calculate roll, pitch and yaw angles of the drawbar relative to a frame of the motor grader.

Abstract: A technique is directed to methods and systems for detecting the presence of a machine operator. In some implementations, an operator presence system monitors a machine to determine whether an operator is present in an operating machine. The operator presence system collects input data from sensors or devices on the machine and determines whether the operator is in the operator seat. During operation, if an operator is determined to not be in the operator seat, the operator presence system can generate and send notifications (e.g., visual or audible warnings) to alert the operator to sit in the operator seat.
