  • Bucket and thumb combination as a quick decoupling attachment
    Patent number: 5813822
    Abstract: A two-part implement combination for attachment to an excavator arm in which both implement parts share a common axis of rotation relative to one another and relative to the excavator arm and are independently movable. This allows a bucket and thumb combination to be quickly coupled or decoupled as a unit from an excavator arm without sacrificing independence of movement and a common rotational arc.
