Rollbacks are truck beds that roll back and tilt so tractors and equipment can be driven or pulled onto the bed with the winch. Bed lengths range from 22 to 28 feet and load capacity varies up to 30,000 pounds, depending on the size of the truck. Hydraulics power the rollback and winch systems. These units are versatile for hauling small to medium-sized tractors and equipment. State and federal regulations must be observed as well as safe loading practices.
