ABSTRACT:
A machine for cultivating the soil has a main transverse beam carrying a transverse tool-shaft driven to drive wobble bearings on the tool-shaft, thereby to oscillate a plurality of tool holders having lever arms guided for transverse swinging movement in the beam. The tool holders mount the tines by substantially U-shaped elements of spring metal, each having its arched portion pointing in the direction of travel with the lower free limb connected to a tine and the upper free limb connected to a lever. The U-shaped elements are configured at the arched portion to have a width such as to have the forward portions of the elements in the direction of travel sweep in their transverse rocking movement a virtually continuous area extending over substantially the entire width of the main beam.
