ABSTRACT:
A rotatable tilling device for tilling ground material, the device consisting of a rotatable shaft having an upper end, a lower end, and having an axis of rotation extending from its upper end to its lower end; a plurality of ground tilling tines, each ground tilling tine having an upper end and a lower end; and, upper and lower tine mounting structure capable of attaching the ground tilling tines to the rotatable shaft so that they span between the tine mounting structure, so that upon rotation of the rotatable shaft the ground tilling tines orbit about the axis of rotation, so that on contact of the rotatable shaft with ground material, the ground tilling tines also contact the ground material, and so that the ground tilling tines may flexibly bend between the upper and lower tine mounting structure; the upper and lower tine mounting structure fixedly attaching the ground tilling tines to the rotatable shaft.
