ABSTRACT:
A method and apparatus for marking and severing a tree trunk, such apparatus including a grapple for grasping a tree and a severing device spaced therefrom for severing the tree. A marking device is located at a position on the side of the grapple device opposite to that of the severing device and in selected spaced relation with the latter to effect a mark on the tree wherein a subsequent severing operation is to be effected. The spacing between the marking and severing device indicates the length of log to be severed. The marking device is actuated automatically upon effecting a severing operation such that during severing the mark is effected and which may be subsequently utilized visually to indicate appropriate positioning for the subsequent severing operation. Alternatively, automatic means may be utilized to detect the mark and such automatic detection actuating suitable means to effect the desired severing operation. Stripper arms are included on the device for removing limbs from the tree as it is propelled endwise by a tree propelling means consisting of feed rolls or the like.
