  • Rotary tiller attachments for facilitating turning
    Patent number: 5095996
    Abstract: A conventional rotary tiller having an engine, an axle with two wheels, a set of tines, handlebars, and an attachment that facilitates turning. The attachment comprises a turntable which is mounted to the tiller opposite the tines in such a way that it remains out of contact with the ground during normal cultivation operations. Turning the tiller is accomplished by pivoting the tiller about the axle onto the turntable, and then rotating the tiller on the turntable to a new direction. The tiller is then pivoted back to resume normal operations in the new direction.
