Abstract: The earth handling components of a scraper of the kind having a hoeing apron mounted on powered articulated linkage are actuated by means of a single operator''s control lever which may be pivoted forwardly, backwardly or to either side and which may be lifted or depressed or rotated in either of two directions, wherein each motion operates a different one of a plurality of electrical switches which control solenoid valves operating fluid jacks coupled to the several scraper components. Ten different scraper component movements may be initiated by appropriate positioning of the single lever, either individually or in certain selected combinations.
