<p>An improved blade assembly for a tree harvester shear. The blade assembly comprises a horizontally oriented primary blade member which is narrow relative to its length, and a plurality of vertically oriented secondary blade members or splitter bars which are welded or otherwise fastened to the underside of the primary blade. The plural splitter bars, the narrow primary blade, and the open spaces formed behind the primary blade and between the splitter bars combine to reduce friction and relieve stresses in the cut log, resulting in significantly reduced butt end damage. The above construction also serves to provide a rigid blade assembly with little tendency to climb as it moves through a tree trunk. Accordingly, shear blade damage is minimized.</p> |
