[Travis Gearig] explains the benefits of the pull scraper systems. "Pull scrapers work a lot better as far as regular dirt, not wet dirt and rock. You don't have to have a dozer pushing like with a rubber-tire scraper. You cut the dozer out, and you reduce fuel consumption," he notes. "[PuIl scrapers] are more efficient for hauling up to 3,000 or 4,000 ft. After that, a lot of times, we will get trucks in there."
