Abstract
A control system for the hydraulically powered auger of a self-loading auger scraper that has an ejector operated by a hydraulic cylinder. One manual control valve starts and stops the auger in conjunction with loading. A second manual control valve powers the ejector cylinder and simultaneously operates a valve to start the auger independently of the first manual control valve.
