Abstract
A tree felling unit includes a stand on which a clamping device powered by a hydraulic cylinder is pivotally mounted such that the tree to be felled can be clamped against the stand. Also, pivotally mounted on the stand for engaging the tree at about the same level are a chain saw powered by a hydraulic motor and a shearing knife powered by a hydraulic cylinder. The shearing knife performs its shearing movement in the direction against the feed direction of the chain saw.
