Abstract
667,904. Rotary harrows. SONNAILLON, R. Feb. 15, 1950 [Feb. 28, 1949], No. 3867/50. Class 6(i) The teeth 4 of a rotary harrow 5 are cleaned by hoop-like members 1 arranged loosely between the teeth so that they roll along the ground during working, eccentrically of the harrow axis. The hoops may be independent of one another and of circular or polygonal shape, but preferably they are formed as half-hoops secured at their ends to jointing bars 2<SP>1</SP> and interconnected at intervals by longitudinal bars 2. The device is assembled on the harrow by bolts 3 passing through the jointing bars. The hoops are generally, but not necessarily, of smaller diameter than the .harrow.
