  • Patent number: 4572301
    Abstract: An improved tractor pulled earth mover is shown. The improved earth mover is a two-bladed earth scraper having two parallel blades mounted between two supporting side plates. The side plates define a level of ground with respect to which the earth grader is dragged. The side plates have a supporting structure including a mounting for a standard three point hitch for a tractor to permit manipulation, application, dragging and removal of the earth grader. Between the two side plates are located two parallel rigidly mounted blades having three settable depths found specifically advantageous for grading respectively loose sand, coarse aggregates such as rocks, and compacted dirt. The invention discloses a particularly advantageous geometric relationship between the blades and among the blades for optimum grading effectiveness.
