ABSTRACT:
A walk-behind garden tiller having power driven ground wheels and a single shaft 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, resulting in improved power efficiency and easier control of the tiller when operating in adverse soil conditions. For cutting and breaking long vegetation that is carried upwardly by the counter-rotating tines and for guiding such vegetation under the tine shaft so that it does not become entangled about the tine shaft or otherwise clog or impede operation of the tiller, a sloughing device is mounted transversally to and forwardly of the tine shaft. In one embodiment, the sloughing device is a plate disposed in a vertical plane on the longitudinal axis of the machine, and in another embodiment the sloughing device is a rotary disc.
