Abstract A rotary broom attachment for a motor grader which has a mold board and means to adjust the mold board for vertical elevation, side shift and rotary position about vertical and horizontal axes. The rotary broom is mounted behind and parallel to the mold board and has independent adjustment and control means for side shift and vertical positioning of the broom relative to the mold board. Sensors are used to signal automatic shifting of the broom vertically or in side shift to avoid interference with the motor grader structure as well as obstacles in the path of the broom. The downward pressure of the broom is controlled by the proportional lift applied thereto by a hydraulic lift means.
