2094236 9206580 PCTABS00011 A device (1) for working the ground comprises a frame (2) and a plurality of discs (6). Each disc is rotatably mounted on a lying shaft (5) which is provided on the free end of a pivotable standing shaft (4). In order to prevent jamming of the discs (6) by earth thrown up by adjacent discs (6), each standing shaft (4) is placed on the concave side of its associated disc (6). The lying shafts (5) are inclined relative to the ground, thus providing an improved ''digging'' working of the ground. The slope of the shafts (5) relative to the ground can be varied by pivoting a part (26) bearing the standing shafts (4) relative to a fixed part (25) of the frame (2).
