Abstract
A method and apparatus for processing and harvesting trees in which the stem of a tree is encircled by instrumentalities mounted on an elongate member positioned adjacent the stem and the upper portion of the stem then exerts leverage about a fulcrum defined by the encircling instrumentalities to bias a butt end portion of the stem upwardly into engagement with an overlying guide mounted on the member adjacent cutting instrumentalities. Tree stems are processed by being advanced relative to the elongate member toward an automotive vehicle from which the elongate member is supported, while maintaining upward biasing of the stem into engagement with the overlying guide. The tree stem may be processed either into longwood or into shortwood sticks, with the processing beginning either from a growing tree which is harvested in accordance with this invention or from a previously felled stem which is lying on the ground.
