The present invention relates to an earth-working plough that includes a frame (5) which carries shares and moldboards for working formed ridges, and a rubber block (4) disposed between frame and a lower moldboard (3). The invention is characterised in that there is provided between the front attachment of the lower moldboard (3) and the land side (5) of the frame a joint which enables vertical movement to occur between frame and lower moldboard (3), i.e. vibratory movement of the moldboard in a vertical direction occurring when ploughing.
