Barber chair

One technique that can reduce the chance of creating a barber chair is to use a bore cut.

A severely leaning tree which is greater than 12 inches on the stump can "barber chair" by splitting prematurely during the felling cut so that the butt of the main tree trunk pivots upward toward the chainsaw user's head, if special felling techniques are not used.

Figure 4-6 A shows a tree that barber chaired when the back cut was too low. Figure 4-6 B shows why it's called a “barber chair”.

This is because the trunk can “barber chair” before it falls.
