7 Different Types of Undercuts in Tree Felling

An undercut is a Read this article fundamental aspect of tree felling, serving as the initial cut made in the tree during the felling process. This cut is not just the first step in bringing a tree down; it’s a strategic move that significantly influences the direction in which the tree will fall. The primary purpose of an undercut is to create a controlled path for the tree’s descent, ensuring both the safety of the feller and the protection of the surrounding environment

Very High Back Cut and Uneven Notch
The Very High Back Cut and Uneven Notch technique is a sophisticated method used in tree felling for situations demanding high precision in the direction of the tree’s fall. This approach involves making a back cut higher up on the tree and creating an uneven notch at the front. It is particularly effective for trees with irregular shapes or significant leans. The higher backcut alters the tree’s center of gravity, providing more control over the fall, while the uneven notch guides the tree more precisely in the desired direction. This technique is invaluable in urban areas or near structures where precision is paramount.

Shallow Notch
The Shallow Notch technique is characterized by removing less wood from the tree, resulting in a shallower cut. This method is advantageous in situations where space is limited or when the tree is naturally aligned to fall in a straight line. By making a shallower notch, the tree feller can ensure a more controlled and predictable fall, especially in confined spaces. This technique is less invasive and can be particularly useful in residential areas or when working close to other trees or structures.

Thick Hinge
Creating a Thick Hinge involves leaving a substantial amount of wood at the hinge point during the felling process. This technique is designed to slow down the tree’s fall, thereby providing the feller with greater control over the descent. It is especially useful in dense forests or in proximity to buildings and other structures where a slow, controlled fall is necessary to avoid damage. The thick hinge acts as a buffer, reducing the tree’s momentum as it falls.

Shallow Notch and Thick Hinge
The combination of a Shallow Notch and a Thick Hinge is a strategic approach used in challenging felling environments. This method merges the benefits of both techniques, offering enhanced control and precision. The shallow notch ensures that the tree does not pivot too aggressively, while the thick hinge slows the fall, allowing for a more measured and controlled descent. This technique is particularly effective in uneven terrains or in areas where other trees or structures could be impacted by the fall.

The Conventional Method
The Conventional Method is the most widely used technique in tree felling. It involves making a standard notch at a conventional depth and angle. This method is versatile and suitable for a wide range of trees, particularly those of average size and in standard felling conditions. It provides a good balance between control and ease of execution, making it a go-to choice for many professional tree fellers.

Very Shallow Notch
The Very Shallow Notch technique is employed when minimal movement of the tree is desired during the fall. This method is particularly useful for trees that are already leaning significantly in the desired direction of fall. By making a very shallow notch, the tree feller can utilize the tree’s natural lean to guide its descent with minimal additional force or direction needed. This technique is often used in sensitive environments where the surrounding area needs to be preserved.

Low Back Cut
The Low Back Cut technique involves making the back cut lower than usual. This method affects the leverage and speed of the tree’s fall and is often used for larger trees or in situations where specific lean issues need to be addressed. By cutting lower on the trunk, the feller can manipulate the falling process, providing more control over how the tree descends. This technique is particularly useful in managing trees with complex leans or in areas where precision is crucial to avoid damage to nearby structures or vegetation.
