ABSTRACT:
A soil working implement for use in forming a raised soil bed is disclosed. The implement includes a carriage assembly and a plowing tool mounted for rotation on the carriage assembly. The plowing tool includes a cylindrical rim and an array of soil digging teeth rigidly secured to the rim and projecting radially with respect thereto for moving soil laterally relative to the line of travel of the implement. Each tooth is characterized by an inclined face slanting away from the direction of rotation of the rim and converging to form a cutting edge which is canted at an oblique angle with respect to the line of travel. A plurality of the plowing tools are mounted along a rotatable shaft which extends transversely with respect to the line of travel of the carriage assembly, and the cutting edges of the teeth in adjacent pairs of the plowing tools are oppositely canted with respect to each other for lifting and laterally displacing soil toward or away from the common center line of travel of the adjacent pair of tools. A method of tilling soil for farming a row crop in a field which can be carried out by the apparatus of the invention is also disclosed.
