<p>A boom assembly for a delimber having an operator boom with first and second ends and a connector boom having first and second ends. Pivot means pivotably connect the second end of the operator boom to the first end of the connector boom, the connector boom aligned with the operator boom. A delimber boom, having a delimbing head at one end, is mounted near the one end to the connector boom at its second end. The delimber boom extends rearwardly from the connector boom and at a slight angle, when the boom assembly is viewed from above, to the connector boom. The delimbing head is mounted on the bottom of the delimber boom and the boom assembly includes at least two butt plates, each movably mounted on the bottom of the delimber boom. The butt plates are spaced apart longitudinally and spaced from the delimbing head toward the other end of the delimber boom. Operating means, associated with each butt plate on the delimber boom, selectively move the butt plate between an operative position where it is generally transverse to the delimber boom and aligned with the delimbing head to receive the butt end of a tree being delimbed by the delimbing head, and an inoperative position where it is out of the way of the butt end of a tree being delimbed. The invention also covers a delimber using the delimbing boom, and a method of using the delimber.</p> |
