Abstract

A rotary broom attachment (2), for a motor grader which has a mold board (4) and means (8) to adjust the mold board for vertical elevation, side shift, and rotary posi­ tion about vertical and horizontal axes, is mounted behind and parallel to the mold board and has independent adjust­ ment and control means (28, 29) 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 struc­ ture as well as obstacles in the path of the broom. The down­ ward pressure of the broom is controlled by the proportional lift applied thereto by a hydraulic lift means.
