The Back Cut |
|
|
The
back cut is the third and final cut and is made on the opposite side of the notch.
The back cut disconnects almost all of the tree from the stump leaving a
hinge that helps to control the
tree's fall. |

1. Starting Point
Important - begin on the opposite side of the
notch at the same level as the notched corner |
|
|
2. Angle of Attack
Important - cut flat along a horizontal plane |
|
|
3. Ending Point
Very important - stop
at the point that will leave a hinge width that is 1/10 the tree's diameter |
