ABSTRACT:
A soil cultivating machine has a front row of subsoil penetrating tools and a second soil working member or row of members that work the top soil. The tools can be strip-shaped tines, at least some of which have plate-shaped elements pivoted to their lower ends. The elements or tines are connected to an eccentric mechanism that periodically raises and lowers the elements as the machine is operated. The second soil working member can be a row of tined rotors or an elongated further working member that extends transverse to the direction of travel and works the top soil from a direction that is different from the direction of movement of the strip-shaped tines. Intermixing the worked top soil and the subsoil is prevented.
