.~.~> Scraper adjustable about vertical axis of annular support {1}
DEFINITION
Classification: 172/791
(under subclass 781) Apparatus comprising three or more actuators, each operable independently of the others to adjust the position of the scraper relative to the vehicle frame extending between the front and rear ground supports, and acting between the frame and scraper.
(1) Note. If a single power source, such as an engine power take off or hand wheel, is connected by clutches to end elements, such as shafts, links or the like, so that a plurality of such elements can each be moved independently of each other to adjust the position of the scraper, then these are considered to be plural, independently operable actuators corresponding in number to the number of independently movable adjustment points.
