When choosing a wedge, what is the recommended size?

The recommended size for a wedge being half the size of the tree diameter is based on the need for effective mechanical leverage when felling a tree. A wedge that is proportional to the tree's diameter allows for proper insertion into the cut, helping to direct the fall of the tree and prevent it from pinching the saw. By using a wedge that is half the size of the tree diameter, the operator ensures adequate support and stability during the felling operation.

This sizing is critical for safely guiding the tree in the intended direction. Choosing a wedge that is too small can lead to insufficient leverage, while one that is too large may not fit properly in the cut or could create excessive strain on the saw, making it difficult to control the felling direction. Understanding this balance is essential for effective and safe chainsaw operation in wildland contexts.
