I. ABSTRACT OF THE DISCLOSURE. A soil tillage machine has a straight pull-type main frame. Attached to the main frame are standards to which novel deep tillage knives are attached. A pair of wings are attached to the lower part of the narrow knife shaped main blade. The wings slope downwardly at an angle of approximately 10% relative to a line parallel to the soil surface. The front portion of the wing bottom lies in a plane parallel to the soil surface. The back portion of the wing bottom lies in a plane parallel to the top surface of the wing. When the tillage machine is pulled through the soil, The wings on the knives lift and fracture the soil the entire width of the machine, breaking up any hard pan. This lifting action aerates the soil with minimal displacement and mixing of surface soil. The tillage machine can be used both before and after planting of crops.
