Shaft-driven vibrating harrow with a transmission case, in which at least one swashblade drive is arranged for driving the harrow bars extending transversely relative to the direction of travel in to-and-fro movements, there being mounted in a transmission case the drive rocker for the to-and-fro drive of the harrow bars, which rocker is mounted in the transmission case on the underside of the forked rocker by means of a bearing. In order in a constructively simple way to obtain a substantially quieter running of the vibrating harrow, especially of the vibratory drive, there is arranged in alignment with the forked rocker (5) rotating to and fro about a vertical axis a further bearing (7) for mounting the forked rocker (5) on or in the transmission case (4). <IMAGE> |
