Abstract
In accordance with one or more aspects, a circle drawbar for a motor grader has a drawbar frame having two elongated members, and a circle frame that has a surface defined by an inner and outer diameter. The circle frame has a circle gear located radially inward of the inner diameter, allowing the circle frame to be rotatable relative to the drawbar frame around an axis of the circle gear. A platform having a top, bottom, and an edge depends from the drawbar frame and covers the circle gear. A debris remover is connected to the platform and removes debris from the surface of the circle frame as the circle frame rotates.
