Abstract
An elevating scraper having a four-wheeled tandem running gear. The elevator is divided into parallel loading paths to accommodate a drive line between the paths. Thus the scraper is particularly suited for towing by a tractor having a power takeoff at the rear. The construction also features a knock-down assembly for minimum utilization of shipping space.
