Abstract
There is provided a felling head for attachment to a boom. The felling head includes an upper part and a lower part. The upper part has at least one brace portion and a grapple adapted to clasp a tree trunk against the brace portion. The lower part includes a circular saw blade mounted in a plane perpendicular to the longitudinal axis of a tree clasped between the brace portion and the grapple. The leading edge of the circular saw blade projects beyond the location of the brace portion by a distance at least as great as the diameter of a tree being felled so that such tree can be cut through by the saw blade before the tree comes into contact with any other part of the felling head, including the brace portion.
