The vibrating harrow has a supporting arm (35) which is fastened to a tractor and extends transversely relative to the direction of travel (A) and on which two longitudinal arms (38) extending in the direction of travel (A) are mounted pivotably by means of axles (36). Articulated on the longitudinal arms (38) are implement carriers (40) which extend parallel to the supporting arm (35) and which are likewise connected at their ends, via joints (41), to semicircular arms (42) likewise serving as implement carriers. Working members (44) in the form of rotors having tines projecting downwards are arranged rotatably on the implement carriers (40, 42). During operation, the two longitudinal arms (38) are moved to and fro periodically via an auxiliary shaft (64), a crank mechanism (60, 61) and a rod (59), with the result that the implement carriers (40, 42) likewise move to and fro. This periodic lateral displacement of the implement carriers (40, 42) ensures a uniform tilling of the soil. <IMAGE> |
