In the 1970s, a professional skills competition for forestry workers was created that tested five disciplines based on their daily work: tree felling, chain fitting, bucking by combined cuts, precision bucking and limbing.
In this article, we present some basic information about precision bucking.
Precision bucking: Knowing when to stop
Contestants must cut off a disc measuring 30 to 80 mm in thickness from two trunks sawing from the top down and at right angles to the longitudinal axis of the tree trunk. Contestants try to cut off the disc as completely as possible without damaging the board underneath, which would disqualify that attempt. The task is made more difficult by a layer of wet sawdust that covers and obscures the contact zone between the trunk and the baseboard.
The competition focuses on how well participants can handle a chain saw. They are evaluated on their speed, accuracy and safety in each discipline. A few tenths of a millimetre often mean the difference between victory and defeat.
STIHL supports the World Logging Championships at both the national and international levels.
