8 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling
8.6.3
Conventional Notch
For a conventional notch:
The felling notch determines the direction of the tree's fall.
Make the felling notch perpendicular to the line of fall you
have determined, close to the ground.
Be aware of conditions such as wind, limb and foliage
structure, tree lean, the slope of the terrain and other
factors that could alter the direction of fall.
Cut down at a 45° angle to a depth of approximately 1/5 to
1/4 of the trunk diameter.
Make a horizontal cut that meets the bottom of the first cut.
Remove the resulting 45° piece. The size of the wedge will
vary by tree size. The larger the tree, the larger the wedge.
This model chain saw is not intended for felling large
diameter trees.
8.6.4
Open-faced Notch
For an open-faced notch:
The felling notch determines the direction of the tree's fall.
Make the felling notch perpendicular to the line of fall you
have determined, close to the ground.
Be aware of conditions such as wind, limb and foliage
structure, tree lean, slope of the terrain and other factors
that could alter the direction of fall.
Cut down at a 50° angle to a depth of approximately 1/5 to
1/4 of the trunk diameter.
Make a second cut that meets the bottom of the first cut
from below at a 40° angle.
Remove the resulting 90° piece. The size of the wedge will
vary by tree size. The larger the tree, the larger the wedge.
This model chain saw is not intended for felling large
diameter trees.
