ABSTRACT:
A convertible garden tiller includes a chassis, a pair of wheels supporting the chassis, an engine mounted on the chassis capable of driving the wheels in a given direction and a plurality of earth working tines. Each tine is generally unidirectional, having a preferred direction of movement through the earth and is disposed on an elongated tine shaft which rotates about a longitudinal axis in response to operation of the engine. The tine shaft is also pivotable 180 degrees about a transverse axis, to selectively rotate the tines in the given direction as well as the second direction. This construction therefore provides that each tine moves through the earth only in its preferred direction of movement. The tiller also includes guide handles which are selectively pivotable from a position above the tines to a position above the wheels for alternately converting from a rear tine mode to a front tine mode. The wheels are driven by the engine when the guide handles are disposed in the rear tine mode and are automatically disengaged from the engine when the handles are pivoted to convert the tiller to the front tine mode. Further, the tines are replaceable with other implements such as an edger, aerator, power rake, snow-thrower or sickle bar.
