ABSTRACT:
A cultivating machine has subsoil tines and corresponding plate-shaped elements are pivoted to the lower portions of the tines. A driving mechanism, including at least one eccentric is connected to one or more of the elements or tines and the elements are caused to pivot up and down at their working depths to only partially raise the subsoil. The driving mechanism can also be connected to a further soil working member with soil engaging bars positioned to oscillate and work the topsoil.
