1. Starting Point
Important -- begin at any height as long as you
allow enough room for the undercut |
|
|
2. Angle of Attack
Important -- cut downward at an angle of 45 degrees |
|
|
|
3. Ending Point
Stop when the cut reaches 1/4 to 1/3 of the trunk's
diameter or when the cut reaches 80% of the tree's diameter at
breast height |
