Abstract: An excavating device for scraping away the high shoulder material on the road sides. The device includes a rotating drum on which are permanently attached tooth-supports arranged in a helix. On the supports are fastened spikes and teeth, different types for different terrain. Scraped earthen material can be dispersed or windrowed and by arranging the supports on opposite helixes or by reversing rotation, the material can be dispersed or windrowed right or left of the rotating drum. A frame is employed to support the rotating drum, and the drum can be articulated to various working positions by hydraulic cylinders. A retractable hood is located above the rotor and movable deflectors are provided for material flow control. Tracer wheels facilitate control of the desirable digging depth.

Abstract: A ditch digging and/or cleaning apparatus designed to cut a multitude of ditch profiles includes a rotating drum on which are permanently attached tooth supports. On these supports are fastened spikes and teeth, different types for different terrain. Removed ditch material can either be dispersed to the right or windrowed to the left of the rotating drum, over the far side bank or the road side bank of the ditch, by rotatably positioning the drum.A frame is employed to support the rotating drum, to position it to the various working positions and to connect it to the carrier vehicle. This frame consists of a fixed section that connects to the carrier vehicle and a rotatable section that supports the rotating drum. Also included are fixed and movable deflectors that direct the material flow to the desired direction. This frame can be attached on tractor pulled and powered carriers, or on self propelled extending boom carriers.
