An agricultural machine has a frame and a rear tilling member connected to the remainder of the machine by a linkage that has at least four pivots. Driving means from a prime mover p.t.o. is connected via at least one eccentric and the linkage to reciprocate the tilling member in horizontal and vertical movements to work the top soil. Tines fixed to a supporting beam, that is pivoted to the rest of the frame, are also moved by the driving means in advance of the tilling member to work the top soil and subsoil. |
