The boom includes a base portion and a movable portion. The base portion is configured to be supported by the frame, and the movable portion is supported for sliding movement relative to the base portion in a direction parallel to a longitudinal axis of the base portion. The boom includes a wrist portion pivotably coupled to the movable portion at a pivot joint. The cutting device is supported on a distal end of the wrist portion. The fluid actuators are coupled between the base portion and the wrist portion.
