Tree delimber

摘要

A portable support structure defines a generally horizontal path along which an elongated log may be longitudinally shifted and mounts an upwardly opening tree trunk supporting and guiding crotch structure therefrom as well as a pair of curvilinear limb stripping blades mounted for movement toward and away from each other and defining a tree trunk encircling cutting opening therebetween generally coaxial with the aforementioned path. Log presence sensing structure is spaced along the path from the blades and mounted from the support structure for movement between upper and lower limit positions and resiliently yieldable motion transmitting structure is operatively connected between the log pressure sensing structure and the blades for swinging the latter toward and away from each other responsive to down and up movement, respectively, of the log pressure sensing structure.
