Conventional Cut
Felling notch (C) – determines the 
direction of the fall
For a conventional cut:
N Properly place felling notch 
perpendicular to the line of fall, 
close to the ground.
N Cut down at approx. 45° angle to a 
depth of about 1/5 to 1/4 of the trunk 
diameter.
N Make second cut horizontal.
N Remove resulting 45° piece.
Open-face Technique
Felling notch (C) – determines the 
direction of the fall
For an open-face cut:
N Properly place felling notch 
perpendicular to the line of fall, 
close to the ground.
N Cut down at approx. 50° angle to a 
depth of approx.1/5 to 1/4 of the 
trunk diameter.
N Make second cut from below at 
approx. 40 degree angle.
N Remove resulting 90° piece.
Making Sapwood Cuts
N For medium sized or larger trees 
make cuts at both sides of the trunk, 
at same height as subsequent 
felling cut.
N Cut to no more than width of guide 
bar.
This is especially important in softwood 
in summer – it helps prevent sapwood 
splintering when the tree falls.
