TEXT VERSION OF TITLE SLIDE:
Title: Dangerous Results of Incorrect Felling (continued)
Type: Text and Image Slide
Content:
Dutchman
- The seat that interferes with the smooth closing of the notch
- Caused when one of the notch cuts is made too deep and extends beyond the endpoint of the other notch cut, known as "Bypass"
Kickback
- When a falling tree hits the ground or other object it can bounce back causing the log to move back over the stump with
great force. This is the main reason you should never stand or retreat directly behind the tree.
- Increased chance of kickback by not making the back cut above the notch on a conventional or Humbolt notch.
Stalled Tree
- A tree that has just begun to fall but is stopped by its own stump. This is almost as dangerous as a lodged tree
and requires a machine to push it over.
- Caused by a Dutchman Notch.
