Abstract: A ripper tooth means is disclosed in combination with a wheeled vehicle having a pair of forwardly extending arms, a frame secured to and extending between the arms, and a horizontal shaft removably mounted on the frame. The ripper tooth means is comprised of an elongated arm means having upper and lower ends and a longitudinal axis. A ripper tooth element is mounted on the lower end of the arm means. A sleeve element having a longitudinal axis extending at right angles to the longitudinal axis of the arm means is mounted on the upper end of the arm means. The sleeve element is slidably mounted on the horizontal shaft. A stop element is mounted on the sleeve element and is adapted to engage a portion of the frame upon limited rotational movement of the arm means with respect to the frame.
