ABSTRACT:
A cutting tool assembly for a log debarker. A cutting tool is provided having an elongated leading cutting edge and a key member. The key member fits into the load carrying slot portion of the head of the tool shaft, and the tool is then secured to the tool shaft head with a plurality of retainer bolts. The tool shaft head is machined at an angle of generally five degrees relative to the axis of an incoming log so as to slant the orientation of the tool and its leading edge. Thus, an incoming log will impact initially a central location of the tool and not its full length. A tensioning device places the tool shaft in tension about a pivot axis and the outermost tip of the tool continually points towards the center line of an incoming log as the tool shaft pivots about this pivot axis. Every other tool is extended a slight distance further towards the incoming log than the adjacent tools by an extension spacer or washer to further reduce the shock loading previously encountered.
