Abstract
A feller head for a tree felling apparatus comprises a first forward projection adjacent a tree trunk receiving recess. A chain saw is mounted within the first projection and extends away from the first projection in the direction of the recess. A motor for powering the chain saw is operatively connected to the chain saw within the first projection. There is a mechanism for slidably moving the chain saw along a curved path within the projection. The path is convex in the direction of the recess.
