• Felling with Finesse:
  • Planning is Paramount: Before making a single cut, I assess the tree, the terrain, and the surrounding environment. I consider the tree’s lean, wind direction, and potential hazards.
  • The Notch: A properly executed notch is crucial for controlling the direction of the fall. I typically use a 70-degree open-face notch.
  • The Hinge: The hinge is the uncut wood between the notch and the back cut. It acts as a guide, controlling the speed and direction of the fall. I aim for a hinge that’s about 10% of the tree’s diameter.
  • The Back Cut: The back cut should be slightly above the notch and leave enough wood to form the hinge.
• Bucking for Efficiency:
  • Log Length Optimization: I determine the optimal log lengths based on the intended use of the timber. For firewood, I typically cut logs to 16-18 inches. For lumber, I consider the dimensions of the intended boards.
  • Spring Pole Awareness: Be aware of spring poles, which are branches or small trees that are bent under tension. These can snap back violently when cut.
  • Cutting Techniques: Use appropriate cutting techniques to avoid pinching the saw. Wedges can be used to prevent the log from closing on the bar.
• Data-Backed Insights: Studies by the U.S. Forest Service have shown that proper felling techniques can reduce timber waste by up to 20%. Furthermore, optimizing log lengths can increase lumber yield by 10%.
• Personalized Story: I once underestimated the lean of a tree and nearly had it fall in the wrong direction. Luckily, I was able to correct my mistake before it was too late. The experience taught me the importance of careful planning and attention to detail.
