Abstract
A draft apparatus for a motor grader comprises a draft frame, a circle, a moldboard, a circle drive, a guard, and a seal. The circle comprises a circle gear. The circle is connected to the draft frame for rotation relative to the draft frame about an axis of the circle gear. The moldboard is mounted to the circle for rotation therewith about the axis. The circle drive is mounted to the draft frame and comprises a pinion engaging the circle gear to rotate the circle and the moldboard about the axis. The guard depends from the draft frame so as to provide radial cover of the circle gear and the pinion relative to the axis. The seal establishes a sealed connection between the guard and the circle.
