Back to the Chainsaws: Applying Metrics to Bar Length Decisions
Now, let’s bring this back to the original question: which fits best, a 16-inch or 20-inch bar on your Stihl chainsaw? The answer lies in understanding how bar length impacts the metrics we’ve discussed.
- Time Per Task: A longer bar can speed up felling larger trees, but it also requires more power from the saw. If your saw isn’t powerful enough, the longer bar will actually increase your time per task.
- Wood Volume Yield Efficiency: A longer bar can potentially lead to more efficient cutting of larger logs, but it also increases the risk of kickback if you’re not experienced. A kickback can lead to wasted wood and potential injury.
- Fuel Consumption: A longer bar generally requires more power and therefore more fuel.
- Equipment Downtime: Using a bar that’s too long for your saw can put extra strain on the engine, leading to increased wear and tear and potentially more downtime.
Therefore, the best bar length depends on several factors:
- The Power of Your Chainsaw: A longer bar requires a more powerful saw. Check your chainsaw’s manual for the recommended bar lengths.
- The Size of the Trees You’ll Be Cutting: If you’re primarily cutting small trees and firewood, a 16-inch bar is likely sufficient. If you’re felling larger trees, a 20-inch bar might be necessary.
- Your Experience Level: A longer bar is more challenging to control and increases the risk of kickback. If you’re a beginner, start with a shorter bar and work your way up as your skills improve.
Here’s my recommendation:
- For General Firewood Cutting and Small Trees (Under 12 Inches Diameter): A 16-inch bar is typically sufficient and offers better maneuverability and control.
- For Felling Larger Trees (12-20 Inches Diameter): A 20-inch bar may be necessary, but only if your saw is powerful enough and you have the experience to handle it safely.
- For Trees Over 20 Inches Diameter: Consider a larger chainsaw with an even longer bar.
Don’t just take my word for it. Track your own metrics!
Before making a decision, I recommend conducting a simple experiment. Use your existing chainsaw with its current bar length to process a cord of wood. Track your time per task, fuel consumption, and wood volume yield efficiency. Then, if possible, borrow or rent a chainsaw with a different bar length and repeat the experiment. Compare the results to see which bar length performs best for your specific needs and conditions.
