Sthil PolyCut: Efficient Wood Processing Tips (5 Pro Techniques)

Wood processing, whether for lumber, firewood, or other uses, involves a series of steps from felling the tree to preparing the final product. Each step presents its own challenges, requiring specific tools and techniques. The Stihl PolyCut, often used on brushcutters and trimmers, offers a unique solution for certain tasks, particularly those involving smaller diameter wood and precision cuts.

Key Terms and Concepts:

• Green Wood: Freshly cut wood with high moisture content. It’s heavier and harder to split than seasoned wood.
• Seasoned Wood: Wood that has been dried to reduce its moisture content, making it lighter, easier to burn, and less prone to rot.
• Diameter at Breast Height (DBH): A standard measurement of tree trunk diameter taken at 4.5 feet (1.37 meters) above the ground. It’s used to estimate tree volume and age.
• Kerf: The width of the cut made by a saw blade or chainsaw chain.
• Brushcutter: A powerful tool, often gasoline-powered, used for clearing brush, weeds, and small trees. The PolyCut head is an attachment commonly used with brushcutters.

1. Precision Felling of Saplings and Small Trees

While a chainsaw is the go-to tool for felling larger trees, the PolyCut excels at precisely felling saplings and small trees up to about 4 inches in diameter. This is particularly useful in forest thinning operations, clearing overgrown areas, or selectively removing unwanted trees.

Step-by-Step Guide:

1. Assess the Tree: Before felling, assess the tree’s lean, branch distribution, and any potential hazards (e.g., power lines, obstacles). Determine the desired felling direction.
2. Clear the Area: Remove any brush, debris, or obstacles around the base of the tree to ensure a clear working area.
3. Stance and Grip: Maintain a stable stance with your feet shoulder-width apart. Grip the brushcutter firmly with both hands, keeping your elbows slightly bent.
4. Cutting Technique: Start cutting at the base of the tree, making a notch on the side facing the desired felling direction. This notch should be about 1/3 of the tree’s diameter.
5. Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of uncut wood to control the felling direction.
6. Felling: As you complete the back cut, the tree should begin to fall in the desired direction. Step back and away from the falling tree.
