ABSTRACT:
Three booms (20,30,50) form an articulated boom structure that is mounted on a pivotable base (10). The booms (20,30,50) are extendible into a position in which they extend one from another and are generally parallel to each other. The booms (20,30,50) may be folded into a position in which a workhead (74) attached to the outer boom (50) is positioned to work in the area on the ground near the base (10). The booms (20,30,50) fold into a Z-shaped configuration and may be pivoted to move the workhead (74) in a vertical line reaching to a height of about 40 feet. A rotary cutter (90) is carried by the workhead (74). Opposing jaws (84,86) are carried by the workhead (74) and third boom (50), respectively, and function, when the workhead (74) is pivoted, to grasp debris or to perform a digging operation. The jaw (84) may also be used as a rake. A shroud (82) on workhead (74) prevents debris from flying away from cutter (90) in unpredictable directions.
