摘要： A method and apparatus for harvesting trees includes provision for removing the limbs from a tree and cutting the delimbed tree into logs. The method and apparatus can operate on standing trees or felled trees. In the performance of the delimbing and cutting operation, the tree is gripped at one end with a gripper-shear mechanism. If the tree is standing, the shear cuts the tree at the base of the tree. In both operations, namely, where the apparatus is working on a standing or on a felled tree, a delimbing mechanism is moved along a first length of the tree to delimb that first length of the tree while the tree is supported by the gripper-shear mechanism and the delimbing mechanism. The gripper-shear mechanism is subsequently moved to a position adjacent to the delimbing mechanism so that the gripper-shear mechanism is positioned a predetermined length from one end of the tree. The gripper-shear mechanism is then actuated to cut the tree so that a log having a predetermined length is produced thereby.
