Abstract: A grading machine includes a machine body, a grading blade supported by a circle, a drawbar connecting the grading blade and the circle to the machine body, and a circle drive system. The circle drive system includes a circle drive motor and a gear box. The gear box is configured to engage with and rotate the circle relative to the drawbar around a circle axis. The circle drive motor includes an axis of rotation that is perpendicular to the circle axis, and the gear box includes an axis of rotation that is parallel to the circle axis.

Abstract: The present disclosure is directed to systems and methods for operating a grading machine. The method includes (i) receiving information indicating a current position of a moldboard of the grading machine; (ii) determining if the moldboard is moving toward an avoidance zone, and the avoidance zone is defined by a distance from a scarifier of the grading machine; and (iii) in response to a determination that the moldboard is moving toward the avoidance zone, adjusting at least one operating parameter of the moldboard or the scarifier of the grading machine.

Abstract: A motor grader including a frame and a scarifier system coupled to the frame. The scarifier system includes a first pin member and second pin member both coupled to the frame and interconnected to one another. The scarifier system also includes a first and second arcuate drawbar arms in spaced relation and coupled to the first pin member and a carriage. An actuator is coupled to the first arcuate drawbar arm and the second pin member to rotate the carriage about a pivot axis of the first pin member.

Abstract: A carriage for a scarifier system of a machine includes a body portion having a leading edge, a trailing edge, and a first height. The body portion includes a first surface and a second surface spaced apart from the first surface, such that the first height of the body portion is defined between the first surface and the second surface. The body portion further includes a first side surface connecting the first surface and the leading edge. The body portion includes a second side surface connecting the second surface and the leading edge. At least one of the first side surface and the second side surface includes a beveled profile. The carriage also includes a plurality of shank attachment portions fixedly coupled to the body portion. Each shank attachment portion extends from the second surface of the body portion. Each shank attachment portion defines a second height.

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.
