Abstract

A hand-held power driven cultivator incorporating a pair of ground working implements or tillers mounted on a pair of laterally spaced vertical shafts depending from a motor and drive train enclosing housing. The tillers are counter-rotated and include interdigitating tines which engage and move the earth forwardly. A barrier freely surrounds each tiller supporting and driving shaft, and completely encloses the shaft between the tiller and the overlying housing. A scraper blade is associated with each barrier and includes a scraping edge spaced slightly from the barrier so as to enhance the ability of the barrier to repel or prevent the accumulation of weeds, roots, debris, and the like. Support and manipulation of the housing is provided for by an elongated handle including an upper fixed hand grip and power switch, and a lower adjustable hand grip.
