Bucking
Bucking is the sawing of a log or fallen tree into smaller pieces.
There are a few basic rules which apply to all bucking
operations.
• Keep both hands on the handles at all times.
• Support logs if possible.
• When cutting on a slope or hillside, always stand uphill.
Keep in mind that the wood is heavy and that it will bend and
pinch the saw if improperly supported. The trunk will weaken at
the point where you make the cut unless the tree is lying on
perfectly flat ground or supported as shown. If you make the
cut with the tree on the ground, don’t let the saw’s chain dig into
the earth; it is harmful for the saw, and you stand a good
chance of being struck by flying debris.
To cut the trunk, use the bucking and two-cut sequence shown.
The first cut should be no deeper than one-third the trunk
diameter.
