Felling

Felling is the term for cutting down a tree. Small trees up to 6-7 inches (15-18cm) in diameter
are usually cut in a single cut. Larger trees require notch cuts. Notch cuts determine the
direction the tree will fall.
Felling a tree:

Warning: a retreat path (A) should be planned and cleared as necessary
before cuts are started. The retreat path should extend back and diagonally
to the rear of the expected line of fall, as illustrated in fig. 11a

fig 11a

Caution: if felling a tree on sloping
ground, the chain saw operator should
keep on the uphill side of the terrain, as
the tree is likely to roll or slide downhill
after it is felled.

Note: direction of fall (B) is controlled by the notching cut. Before any cuts
are made, consider the location of larger branches and natural lean of the
tree to determine the way the tree will fall.

Warning: do not cut down a tree during high- or changing winds or if there
is a danger to property. Consult a tree professional. Do not cut down a tree
if there is a danger of striking utility wires; notify the utility company before
making any cuts.

General guidelines for felling trees:
Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut
(D). Start making the upper notch cut (C) on the side of the tree facing the felling direction (E).
Be sure you don t make the lower cut too deep into the trunk.
The notch (C) should be deep enough to create a hinge (F) of sufficient width and strength.
The notch should be wide enough to direct the fall of the tree for as long as possible.
