ABSTRACT OF THE DISCLOSURE A felling, delimbing and cutting grapple for a multi- function tree harvester. The grapple frame consists of two support arms joined by a pin, the angle between the support arms being set by a hydraulic actuator. One of the support arms carries an upper delimbing cutter rigidly mounted to the arm, while the other arm carries an upper delimbing cutter on a hinge mounting, this delimbing cutter being guided by the upper delimbing cutter. The lower delimbing cutters are separately mounted on the support arms and by means of the hinge pins and they are driven by the hydraulic actuators and their postitions may be set through the hydraulic actuators or through suitable machine elements, thus permitting the cutters to be set at a distance from the trunk held in the feed rollers during a delimbing operation.
