  • Patent number: 4811794
    Abstract: A garden tilling apparatus has a frame with movable arms extending out of the frame and soil-working tines connected to the forward-most portion of the movable arms. Inside the frame, a crankshaft is mounted coupled to the arms and the arms pivotally attached to the frame. A drive mechanism mounted on top of the frame rotates the crankshaft which in turn reciprocates in an elliptical manner the soil-working tines which engage the soil. Handles extend upwardly from the rear of the frame so that one operator may move and use the apparatus to till the soil.
