ABSTRACT:
The present invention relates to an earthworking implement or attachment adapted to be connected to and powered by a prime mover such as a tractor, front-end loader, or the like. More particularly, the earthworking implement of the present invention is designed to spread and level dirt and soil material in one operation, and thereafter to appropriately generally tamp, pack or compress the dirt or material to a desired density which may customarily be done in layers. Structurally, the earthworking implement or attachment of the present invention comprises a frame structure having a ground engaging roller, sometimes referred to as a tamping roller, rotatively mounted therein, with the frame structure having a blade disposed forwardly thereacross. A driven counterweight assembly is also on the frame structure and when driven the counterweight assembly imparts a vibratory-massaging action causing the roller to tamp, compress, or massage the dirt or soil being passed thereover. To perform a leveling or spreading operation, the frame structure of the immplement is rotated about the axis of rotation of the ground engaging roller to a point where the lower portion of the blade is in a proper position to spread or level dirt or soil material. To accommodate the tamping operation, the frame structure is pivoted with respect to the ground engaging roller about the axis of rotation thereof to a position where the lower edge of the blade substantially clears the ground surface line and consequently as far as spreading and leveling is generally inoperative.
