What is the first cut you make when felling a tree?

The first cut made when felling a tree is the undercut, also known as the notch cut. This cut serves as the initial step in the felling process and is crucial for determining the tree's direction of fall. The undercut creates a notch on the side of the tree facing the intended direction of fall, providing guidance for the tree’s path and reducing the risk of unexpected movements.

Making the undercut involves cutting a section of the tree away at an angle, typically forming a 70-degree angle with the ground, to help direct the tree's weight as it falls. This cut also creates a pivot point, which ensures that the tree falls smoothly and predictably. Proper execution of the undercut contributes significantly to safety and effectiveness during tree felling operations, as it helps manage the tree's center of gravity and promotes a controlled fall.

Using other cuts such as the backcut, hinge, or wedge cut without first making the undercut might lead to an uncontrolled fall, or the tree might not fall in the desired direction. Thus, understanding the function and importance of the undercut is vital for safe and effective chainsaw operation in wildland environments.
