ABSTRACT:
This cultivator includes a base, which is carried by a pair of ground wheels, and a motor mounted to the base above a pair of auger assemblies. The motor shaft extends rearwardly of the base and the auger assemblies include elongate shafts rotatively mounted within sleeves attached to the base. The motor shaft and the auger shafts are connected at their rear ends by a chain and sprocket drive assembly which provides counter-rotational motion in the two auger shafts. The forward ends of the auger shafts are each provided with a screw and spaced radial tines of progressively increasing length.
