ABSTRACT:
A scraper system for scraping and ripping a support surface includes a frame being pulled behind the vehicle. The frame includes an adjustment beam slidably mounted to a front beam. A pair of mounting ends of the adjustment beam extends from opposing ends of the front beam. The frame includes a pair of side walls. Each of the mounting ends of the adjustment beam has one of the side walls coupled thereto. The adjustment beam is slid with respect to the front beam to adjust a lateral positioning of the side walls with respect to the front beam. A scraper assembly is coupled to and extends downwardly from the frame. The scraper assembly scrapes the support surface to smooth out the support surface. The scraper assembly is coupled to and extends between the side walls of the frame.
