  • Patent number: 5564885
    Abstract: An improved and versatile work attachment is provided for a front end loader of the type having hydraulically actuated frame arms for supporting and manipulating a work attachment at the front of the vehicle. The work attachment comprises a scoop or bucket in combination with a laterally extending row of ripper teeth mounted along a lower edge of the bucket and adapted for hydraulic actuation between an upper stored position and a downwardly extending deployed position for ripping earth upon vehicle movement in a reverse direction.
