摘要
A plow sweep construction comprising a generally horizontal plate is provided. The plate includes front and rear marginal edges extending longitudinally of the plate and the center portion of the rear marginal edge includes an integral rearwardly and upwardly projecting mounting shank portion spaced substantially centrally intermediate the opposite ends of the plate and provided for attachment to and support from a tool support member. The front marginal edge portion defines a substantially horizontal edge facing forwardly and the, blade member, at least for the most part, is transversely rearwardly and upwardly inclined. The mounting shank portion includes a lower end portion merging smoothly into the longitudinal central portion of the blade member and the lower end portion and the longitudinal central portion of the blade member, including the front marginal portion thereof, being forwardly convex. Still further, the front marginal edge portion of the blade member includes generally straight relatively angulated opposite end portions defining a forwardly opening included angle of between 90° and 180. degree. with the preferred included angle lying between 135° and 170°. The portions of the rear marginal edge portion of the blade member on the opposite sides of and adjacent the lower portion of the mounting shank portion are downwardly depressed so as to be generally horizontally disposed.
