  • Patent number: 4249612
    Abstract: A travel attachment for rotary tillers is disclosed. The travel attachment comprises a fulcrum attached to a frame of the tiller, and a control bar longitudinally movable along the fulcrum including a lower end engagable with the ground. The upper end of the control bar is laterally movable by hand, and when the lower end of the control bar is engaged in the ground and the upper end is moved forward, a central portion of the bar engages the fulcrum forcing the fulcrum and tiller forward. A depth attachment attached to a forward end of the frame includes a horizontal foot of planar configuration with a forward portion curving upward in an arcuate manner. The foot is supported on the ground forward of the tiller and a vertical distance between a bottom surface of the foot and the bottom extension of the tiller blade determines the depth to which the earth will be tilled.
