Abstract
A wheel that has an alternating tooth structure for improved entry into the soil and movement therethrough for efficient soil lifting and flow, self cleaning and balanced operation. The wheel includes a central hub, four equally spaced spokes extending radially therefrom to a circular flange from which radially extending rearwardly curved, from the direction of travel, teeth extend to work the soil. A tooth of the teeth has a rearward surface that is tapered from one lateral surface to the other and rearwardly to move the soil to one side of the wheel and the adjacent tooth has a rearward surface that is similarly but, oppositely tapered but also rearwardly, to move the soil to the other side of the wheel with the teeth alternating in this sequence around the circumference of the flange.
