ABSTRACT:
A long wearing deep tillage sweep includes a central point member having a leading tip and attached to a shank at an angle to the horizontal of approximately 30 degrees. A pair of wings having the shape of a parallelogram are fixed to the lower, forward portion of the point with the sides of the wings parallel to the forward direction of travel and with the leading and trailing edges extending outwardly from the member and parallel to the surface of the ground when the shank is in the normal field-working position. The top surface of the wings has a shallower angle than the point surface, which, together with the horizontal leading and trailing wing edges, reduces soil disturbance. The wings are closely adjacent the tip of the point member so that the angle of the resultant force on the sweep closely approximates that of a straight point alone and the depth of tillage is more consistent than tools having wings offset a greater distance from the leading tip. The leading portions of the wings are hardened, and the wings and point include upwardly and rearwardly directed rear walls which provide a self-sharpening effect as the leading edges wear.
