Weighing nearly 25,000 pounds, Ashland Industries CS18-HD pull-type scraper is the heaviest-duty offering in the 18-cubic-yard class. It matches tractors with 325 or more horsepower and transfers load to the tractor for improved traction. Lift cylinders are mounted higher to keep out of dirt and rocks. Its four 23.5x25 tires are set back from the bowl, allowing dirt to fall through to the ground without plugging. The 16-inch-diameter, 7/8-inch-thick front pipe is elevated to allow a 22-inch clearance between the front section and the ground. Estimatedlist price: $76,215.
