ABSTRACT:
A device for delimbing trees includes two pairs of opposing curved limb-stripping levers including curved cutting blades for engaging and encircling the trunk of a tree to remove limbs therefrom, and a bottom cutting blade positioned to remove limbs from a lower portion of the tree. The bottom cutting blade is movably mounted so as to move in response to forces imposed on the bottom cutting blade by a tree being pulled through the device. In one embodiment, the bottom cutting blade is vertically movable and is biased upward by a spring device. In another embodiment, the bottom cutting blade is pivotally mounted so as to be pivotable forward and rearward, and an impact tool is arranged to periodically transmit impact forces to the bottom cutting blade in a forward direction so as to drive the blade through a limb.
