Key Concepts: Chainsaws and Wood Processing
Before we dive into the specifics of the Stihl chainsaw, let’s cover some essential concepts.
Green Wood vs. Seasoned Wood
- Green Wood: This is freshly cut wood with a high moisture content (often 50% or higher). It’s heavier, harder to split, and doesn’t burn efficiently.
- Seasoned Wood: This is wood that has been allowed to dry, typically for 6-12 months. Seasoned wood has a moisture content of 20% or less, making it lighter, easier to split, and burns hotter and cleaner.
Types of Logging Tools
- Chainsaw: The workhorse of wood processing, used for felling trees, bucking logs, and limbing.
- Axes and Mauls: Used for splitting logs into firewood. Axes are lighter and better for smaller logs, while mauls are heavier and designed for larger, tougher logs.
- Wedges: Used to assist in felling trees and splitting logs.
- Cant Hooks and Peaveys: Used for rolling and moving logs.
- Skidding Winches: Used to drag logs out of the woods.
Understanding Wood Species
Different wood species have different properties that affect their suitability for firewood and other uses.
- Hardwoods: Generally denser and burn longer and hotter than softwoods. Examples include oak, maple, ash, and beech.
- Softwoods: Burn faster and produce more smoke than hardwoods. Examples include pine, fir, and spruce.
Data Point: Oak, a popular firewood choice, has a BTU (British Thermal Unit) rating of approximately 27 million per cord, while pine has a BTU rating of around 20 million per cord. This means oak produces significantly more heat per volume.
