Abstract

The soil scraper of the present invention is adapted for use with a tractor or vehicle having a three point hitch. The device includes an elongated frame having a three point hitch receptacle mounted on its forward end and having an elongated scraper blade pivotally mounted to its rearward end. The scraper blade pivots about a horizontal axis and power means are provided for controlling the pivotal movement of the scraper blade about this horizontal axis. The frame has a length of at least five feet between the scraper blade and the three point hitch receptacle. The device can be used for scraping out the bottom of drainage ditches or other areas where it is desired to achieve the scraping action without placing the vehicle in the vicinity of the area being scraped.

Claims

1. A soil scraper and leveler for use with a tractor having a three point hitch comprising:

an elongated frame having a longitudinal axis and forward and rearward ends,

three point connection means rigidly mounted on said forward end of said frame and including a pair of spaced apart lower attachment members and an upper attachment member for permitting detachable connection of said forward end of said frame to said three point hitch;

an elongated scraper blade pivotally mounted to said rearward end of said frame for pivotal movement about a horizontal axis extending transversely to said longitudinal axis of said frame;

extensible power means connected to said frame and to said scraper blade for causing said blade to pivot about said horizontal axis;

said frame having a length of at least five feet between said scraper blade and said three point connection means and extending in spaced relation above said scraper blade;

said power means being elongated and including a first end pivotally connected to said frame at a point located forwardly of said scraper blade and spaced rearwardly from said connection means, said power means having a second end pivotally connected to said scraper blade;

said blade being arcuate in cross section with a concave surface facing forwardly, a convex rearward surface facing rearwardly, an upper edge, and a lower edge, said horizontal pivotal axis of said scraper blade being located along a midportion of the blade below said pivotal connection of said power means to said blades whereby extension of said power means will cause said lower edge of said scraper blade to move forwardly toward said forward end of said frame, and retraction of said power means will cause said lower edge of said blade to move rearwardly;

said rearward end of said frame including a pair of downwardly extending frame arms, each of which includes a lower end, said blade being pivotally mounted to said lower ends of said frame arms to form said horizontal pivotal axis.

2. A soil scraper and leveler according to claim 1 wherein said frame arms extend both downwardly and forwardly.

3. A soil scraper and leveler according to claim 2 wherein said pivotal connection of said power means to said scraper blade is located adjacent said upper edge of said blade.
