ABSTRACT:
A tilling machine has a frame with a row of tines or rotatable tined soil working members in a row that extends transverse to the direction of travel. A drive is connected to rock the tines or rotate the tined members during operation. The same drive has an eccentric that links an elongated tilling member to the machine at the rear of the tines. The tilling member is pivoted to the frame and movable through a closed but non circular path by the eccentric and elongate elements of the tilling member are moved through a renoform path to both work and level ground previously worked by the tines. Adjustments to change the working levels of the tines and/or the tilling member can be made by rearranging the linkage connections to the frame.
