ABSTRACT:
A simple pullthrough-type device is disclosed for simultaneoulsy delimbing single or amassed groups of several felled trees. A base and interconnected vertical support cooperatively mount a lower fixed delimbing jaw below a pivotally movable upper delimbing jaw, both carried by the vertical support and extending over the base. The upper delimbing jaw carries a pivotally depending delimbing element to aid in maintaining tree contact during the delimbling process. All delimbing portions of both jaws are provided with knives on their tree contacting surfaces to cut limbs from trees that are reciprocatably moved forwardly and rearwardly through the jaws by separate tree moving apparatus such as either a crawler tractor or a wheeled skidder equipped with either a grapple or chokers.
