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 directly in tapered bores in the tool holders. The tines are secured to the tool holders by bolts threaded into the upper ends of the tines and are provided with break sections, to protect the tool holders.
