Abstract: The apparatus for tilling soil provides a significant reduction in energy consumption. The apparatus includes one or more sweeps which are effective for subtilling the soil as it is moved therethrough. One or more tillers are provided ahead of the sweeps, sufficiently near the path of travel of the outermost ends or tips of the sweep blades so as to disturb or loosen the soil directly in the path of the ends of the blades. By positioning the tillers relative to the sweep tips in this manner, energy consumption may be significantly reduced in comparison to subtilling devices having coulters or other tillers positioned ahead of the center of the sweeps.

Abstract: A method for anchoring and straightening a wall which extends below the ground including the steps of forming a hole in the ground at a distance from the wall, forming an opening in the wall from one side of the wall at a level below the ground, driving a shaft through the opening in the wall until one end thereof extends into the hole in the ground, securing an anchoring device to the end of the member in the hole, attaching a wall plate to the other end of the shaft by threading a nut onto the other end of the shaft and tightening the nut so that the wall plate is forced against the wall to thereby straighten and anchor the wall.
