Apparatus for deep plowing highly compacted soil

Apparatus for loosening compacted soil in a field to a desired depth greater than approximately thirty inches, said apparatus comprising:

• a main beam extending generally in the direction of travel;
• a transverse beam mounted intermediate the ends of said main beam and extending transverse of the direction of travel;
• a first plow point;
• means including a first curved shank for mounting said first point plow on the unplowed side of said transverse beam;
• a second plow point, means including a second curved shank for mounting said second point plow to said main beam, said second point plow having a chisel at the nose thereof, first and second forward wings extending laterally and toward the rear and inclined rearwardly and upwardly to lift and fracture soil, first and second soil lift plates respectively behind said first and second wings for further lifting soil passing over said first and second wings, and first and second rear wings located behind said first and second forward wings respectively and extending laterally thereof for further working soil beyond the lateral reach of said forward wings and adjacent the bottom of said fracture profile;
• said apparatus forming along a first swath a first trough of loosened soil to the desired depth and thereafter successively forming a plurality of troughs of loosened soil adjacent said first trough, each successive trough being formed immediately adjacent a previously formed trough and having a transverse vertical fracture profile of unplowed soil in the general shape of a parallelogram having sides inclined upwardly and toward the unplowed ground, each successive swath being formed by pulling said first point plow located on the unplowed portion of said successive trough and at a depth of approximately one-half said desired depth to loosen soil in the upper portion of said fracture profile, and by further pulling said second point plow located to the rear of said first point plow at said desired depth to loosen the remaining soil in the lower portion of said fracture profile.
