ABSTRACT OF THE DISCLOSURE A tree-processing unit is disclosed. The unit comprises a tubular member detachably secured to the boom support of a conventional motorized equipment, an elongated boom extending through both ends of the tubular member, guide means located within the tubular member for guiding and supporting the boom through the tubular member, and hydraulically-operated means mounted on the tubular member and on the front end of the boom for gripping and delimbing a felled tree. In accordance with one feature of the present invention, the hydraulic lines interconnecting the hydraulically-operated means located at the front end of the boom and the tubular member, are maintained in a tight condition all the time to prevent tangling of the lines with the equipment and other obstacles on the working site. In accordance with a second feature of the present invention, the guide means located within the tubular member includes a plurality of roller bogeys having rollers partially encircling a portion of the outer surface of the boom for guiding the boom through the tubular member. In accordance with a third feature of the present invention, the tubular member is hingedly mounted on the boom support, so as to permit pivotal of the boom support about its horizontal axis to a position substantially parallel to the boom and so reduce the height of the boom above ground to a minimum to permit transportation of the motorized equipment on a trailer under bridges and other overhead obstacles. In accordance with a fourth feature of the present invention, two pairs of jaws are pivotally mounted, one on the tubular member and the other on the front end of the boom, for gripping and delimbing felled trees. The jaws of each pair are mounted in a longitudinally offset position and means are provided for interchanging the relative position of the jaws, so that both jaws can be easily seen by an operator seated at the operator control station, whether this control station is located on the right hand or on the left hand of the boom.
