Made of rugged, cold-tolerant UHMW polymer (the same material used on the runners of dog sleds in the Alaskan Iditarod race), this push-pull scraper will give you the wear of two to three ordinary scrapers. Its unique design lets you push dense materials such as shell corn or pull grain from corners. The 18" x 8" blade is chemical resistant and does not rust or break. Handle sold separately (#CF818PP).
