  • Patent number: 4098344
    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.
