Abstract

A walk-behind garden tiller having power driven ground wheels and a single row of tines which are driven at relatively high speed in a direction counter to that of the drive wheels such that during tilling the tines cut upwardly through the untilled soil at the working face with each pass of the tines penetrating and severing a relatively thin uniform layer of soil, resulting in improved power efficiency and easier control of the tiller when operating in adverse soil conditions. A tine shield overlies the tines for confining flying and turbulent soil during tilling to the immediate area about the tines. The tine shield has a forward extension which defines an extended cavity in front of the tines within which a quantity of partially tilled soil directed upwardly and forwardly by the counter-rotating tines can accumulate for re-working and more thorough pulverization by the tines as the machine proceeds along its forward movement. The illustrated shield extension terminates in a downwardly and forwardly tapered lip for directing such partially tilled soil impinging upon the underside of the shield extension onto a continuously formed mound of partially tilled soil in front of the tines.
