The present invention concerns a rear clod-crusher which comprises a frame 1 which can be connected to the adapter of a tractor or similar working machine, for example to a three-point attachment or the like; a cutter disc 2 which includes a vertical shaft 3 which is mounted on the frame so as to rotate in relation to the latter; a power device 4 for pivoting the cutter disc in relation to the frame; and locking members 5 for locking the cutter disc in relation to the frame. The rear clod-crusher further includes a directional coupling 6, with a free direction and a blocked direction, which is arranged between the vertical shaft 3 and the frame 1 and which is connected to the power device 4 for converting its impact movement to the rotary movement of the vertical shaft in the free direction of the directional coupling. <IMAGE>
