FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method isused to fell large
trees. A notch iscut onthe side of the
tree inthe desired direction offall. A_er
a felling cut is made on the opposite
side oftree. the tree will tend to fail in
the direotion ofthe notch.
NOTE: If tree has large buttress roots,
remove them bef_a making the notch.
NOTCH CUT AND FELLING TREE
• Make notch cut by cuttingthe top of
the notch5rat. Cut through 1/3ofthe
diameter ofthe tree. Next complete
the notch by cutting the bottom. See
illustration. Once notchis cut, remove
the wedge of wood from the tree.
• After removing the wood, make the
foiling cut on the opposite side of the
notch. This is done by making a cut
about two inches higherthan the cen-
ter of the notch. This will leave
enough uncut wood between the fell-
ing cut m',dthe notchto form e hinge.
This hinlgewill help prevent the tree
from faiSngin the wrong direction.

Notching Undercut - Make the notch
1/3 the diameter of the tree, perpendic-
ularto the directionof fail as illustrated.
Make the lower horizontal notching cut
first. This w_l helpto avoid pinching of
eitherthe saw chain or the guide bar
when the second notch is being made.
Falling Back Cut - Make the felling
back cut at least 2 inches (50.Smm)
higher than the hodzentai notchingcut
as illustrated. Keep the fellingback out
parallel to the horizontal notching cut,
Make the felling back cut so enough
wood is left to act as a hinge. The hinge
wood helps the tree from twisting and
falling in the wrong direction. Do not out
through the hinge.
As the feeling cut gets dose at the hinge
the tree shouldbegin to fall. ffthere is

NOTE: Before felling cut is complete,
use wedges to open the cutwhen
necessary to control the direction offall.
To avoidkickback and chain d_ge,
use wood or plastiowedges, but never
steel or iron wedges.
• Be a_ertto signs that the tree is ready
to fall;cracking sounds, widening of
the felling cut, or movement in the up-
per branches.
• As tree starts to fall,stop saw, put it
down, and get away qulcldy on your
planned retreat path.
• Be extremely cautious with pmtJaily
fallen trees that may be poorly sup-
ported. When e tree doesn't feJl oom-
_letely, set the saw aside and pull
own the tree with a cabkl winch,
block and teolde, or tractor. Do not
use your saw to cut down a partially
fallen tree.
