Abstract

A mobile tree-processing machine which includes a platform pivotally mounted on a mobile undercarriage for slewing about a vertical axis and having one or more tree-processing units mounted thereon operative to delimb, debark and/or sever whole trees fed thereto by a boom-and-grapple assembly and propelled through the processing units by feed means consisting of driven feed rollers. The leading end of the processed tree, emerging from he last of the processing units, actuates a cutter mechanism severing selected lengths which are directed by a deflector assembly onto an off-feed conveyor assembly which conveys the processed logs in sequence from the machine, depositing such processed logs at a position removed from the machine onto a suitable supporting surface. The off-feed conveyor, in one instance, is attached to the platform on which the processing units are mounted, and in another instance is independently mounted on the undercarriage for pivotal movement about a vertical axis independent of pivotal movement of the processing assembly.
