Every cut a tree feller makes tells a story, not just of timber removed, but of the relationship between operator, machine, and wood. Understanding tree felling cut types is the foundation of safe, efficient, and professional forestry work. The path you choose through the trunk determines how the tree settles on the ground, how easily it can be processed, and the level of risk involved. Mastering these techniques transforms a dangerous chore into a precise craft, where control and foresight dictate the outcome. This guide breaks down the essential methods used in the field today.
Why Cut Selection Matters Beyond the Obvious
The choice between a hinge and a directional notch is rarely about aesthetics; it is a calculated decision based on physics and environment. Selecting the wrong tree felling cut type can result in the tree falling backwards, splitting vertically, or catching on surrounding obstacles. Professionals assess wind direction, snow load on branches, the health of the tree, and the quality of the wood before the first incision is made. The goal is to manage energy, ensuring the tree falls exactly where you want it, the first time, every time. This precision minimizes waste, protects equipment, and keeps the worksite safe for everyone involved.
The Three Fundamental Felling Cuts
At the core of the practice are three primary structural cuts that dictate the movement of the tree. These are not just slices; they are strategic removal of wood to control tension and compression. The hinge, the back cut, and the directional cut work together to create a balanced release. Understanding the role of each component is essential for anyone looking to move beyond basic techniques and into advanced forestry methodology.
Hinge: The Active Pivot
The hinge is the living wood left behind to act as a hinge, controlling the direction and speed of the fall. It must remain intact and flexible until the tree is mostly down. A well-executed hinge provides the necessary tension to pull the tree over in the desired arc. Key factors include the thickness of the hinge, which should be about 10% of the tree's diameter, and its placement, which must be absolutely level to prevent the tree from twisting off track.
Back Cut: The Release
The back cut is the final severing of the tree, made after the directional notch is established. This cut is lower than the apex of the hinge and is responsible for releasing the tension built up in the wood. The critical rule is to never cut all the way through to the hinge; leaving a small portion of wood, often called the "holding wood," prevents the stump from splitting and maintains control. Precision here is vital to ensure the hinge does not pinch or collapse prematurely.
Directional Notches: Steering the Fall To guarantee the tree falls in the intended direction, a directional notch is created before the back cut is made. This notch acts as a face that pulls the tree over. The shape and angle of this notch are the primary tools a feller uses to combat unpredictable forces like wind or the tree's natural lean. Open-Faced Notch The open-faced cut is the most popular method for modern tree felling due to its high success rate. It involves removing a precise wedge of wood, typically between 45 and 60 degrees, facing the intended direction of fall. This wide opening provides excellent visibility of the hinge and allows for quick correction if the tree begins to fall unevenly. It is the go-to tree felling cut type for handling large trees or difficult terrain. Conventional Notch Also known as a Humboldt notch, this method uses a 90-degree facing cut followed by a horizontal back cut. While it requires less initial cutting than the open-faced style, it offers less margin for error. The narrow hinge is more susceptible to pinching if the tree settles before the back cut is complete. This traditional tree felling cut type is still valuable in specific scenarios, particularly when conserving the amount of wood wasted in the notch is a priority.
