Abstract

A frame including a plurality of transversely extending groundengaging members each having a lower surface parallel and in a plane with the lower surface of the remaining members and upstanding beams adjacent the forward edge thereof adapted to be connected to the central link and lift arms of a three-point hitch so that through movement of one of the arms or the central link the orientation of the plane through the lower surface of the ground-engaging members can be altered to make any desired angle with the surface of the ground.

Claims

1. Apparatus for leveling soil and the like comprising:

a. a frame including a plurality of elongated ground-engaging members each having a generally rectangular cross section fixedly attached together in parallel spaced-apart relationship with the longitudinal axes of said members extending generally transverse to the direction of motion, each of said members having their respective lower surfaces positioned parallel and in a plane with similar surfaces on the remaining members;

b. a forwardmost scraper member encompassing a substantially larger cross-sectional area than said ground engaging members attached to the forwardmost point of said frame in general parallel spaced-apart relationship with said ground engaging members and having an inverted U-shaped cross section for providing some scraping action, the lower edges of said scraper member lying generally in the plane of said lower surfaces of said ground engaging members;

c. upstanding connecting means rigidly attached to said frame for attaching said frame to a three-point hitch connected to draft means so that the position of said frame can be changed to place the plane of said lower edges in any desired orientation relative to the ground;

d. a retaining shoe attached to each end of each ground-engaging member and said scraper member to prevent soil from escaping around either end thereof.

2. Apparatus for leveling soil as set forth in claim 1 wherein the upstanding connecting means includes a generally vertical central beam fixed adjacent the lower end to the frame and constructed for attachment to the central link of a three-point hitch and further includes a beam on each side of said central beam affixed adjacent the lower ends to the frame and angling generally upwardly and forwardly of said apparatus for attachment to the vertically adjustable lift arms of the three-point hitch.

3. Apparatus for leveling soil as set forth in claim 1 wherein the upstanding connecting means is constructed for attachment to a three-point hitch of the first category.
