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: 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 with a motor shaft, a gear box, a gear coupling, and a braking mechanism. The gear box is configured to engage with and rotate the circle relative to the drawbar around a circle axis. The braking mechanism is positioned between the circle drive motor and the gear coupling and is configured to selectively engage the motor shaft.
