Abstract
Apparatus for deep plowing highly compacted soil includes successively forming troughs of loosened soil immediately adjacent a previously formed trough. After each pass the plow leaves a trough of loosened soil having a transverse vertical profile (called a 'fracture profile') in the general shape of a parallelogram with sides inclined upwardly and toward the unplowed ground. Each successive trough is formed by pulling a first set of point plows located on the unplowed side of said successive swath and at a depth of approximately one-half the desired depth to loosen soil in the upper portion of the fracture profile. A second point plow located to the rear of the first plows and at the desired depth is pulled approximately midway of the bottom of the fracture profile to loosen the remaining soil in the lower portion of the fracture profile.
