ABSTRACT:
A control system for the hydraulically powered conveyor, such as an 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.
