Abstract

A garden tiller tine assembly for use with a tiller assembly which includes a drive shaft having a longitudinal axis of rotation includes a rotary blade aligned at a predetermined angle with respect to the axis of rotation. The planar body of the rotary blade is angled at a dihedral angle with respect to a plane normal to the axis of rotation. Upon rotation of the tine assembly about the axis of rotation, the rotary blade oscillates laterally from side to side along the axis of rotation to cut a wider path through the soil than conventional rotary blades.
