Our garden tiller is a twist tiller. Extra long handles reduce the effort of twisting. Does a better job with only a fraction of the effort of older designs. Garden tillers utilizing claws twisted into the ground are a great idea! The sharp, angled claws dig into the ground to break up the hard, packed soil. Like all Yard Butler tools the versatile Twist Tiller has solid steel construction. Yard Butler guarantees all Yard Butler tools for life against any defects in manufacturing or materials.
