ABSTRACT:
A field breaking or tilling implement. The implement is mounted or located at a lower end of a shank which is adapted to be drawn behind a tractor. At the lower forward end of the shank is located a chisel point adapted to be pulled through the soil at a position just below a sub-surface hard pan soil layer. Extending rearwardly from the shank is a plow extension which mounts a plow member in spaced relation from the shank. The plow member is located directly behind the chisel, and serves to lift and break the soil. A method of tilling is also disclosed in which a plow member is pulled through the soil directly behind a chisel member.
