ABSTRACT:
A vibrating harrow with a supporting frame consisting of at least two beams that are positioned one behind another, extend across the direction of travel, and are equipped with soil-cultivation tines. The beams are mounted on the supporting frame by means of rockers and are moved back and forth across the direction of travel during operation through the intermediary of a drive mechanism by the power source of a tractor or cultivator. In order to provide a very simple and effective suspension for the cultivating tines parallel and at an angle to the direction of travel when obstacles are encountered in the soil, the beams are longitudinal beams with a U-shaped cross-section, the open side of each longitudinal beam faces away from the direction of travel, the rockers are mounted on the upper flank of the beams, the tines are mounted on the lower flank of the beams, and the beams are open at the rear over approximately their total length.
