The Ultimate Buying Guide for Your Next Chainsaw
Choosing the right chainsaw makes tough jobs easier. Whether you are clearing storm debris or cutting firewood, this guide helps you pick the best ‘20 Chainsaw’ model for your needs.
Key Features to Look For
Modern chainsaws offer many features. You should check these first:
1. Engine Power and Type
- Gas-Powered: These are strong. They work well for big trees and heavy use. Look at the engine size (measured in CCs). Bigger CCs mean more power.
- Electric (Corded or Battery): These are lighter and quieter. Battery models offer great freedom but need good battery life (measured in Amp-hours or Ah).
- Power Rating: For simple yard work, 35cc or 40V batteries work fine. For serious cutting, aim higher.
2. Bar and Chain Length
The bar is the long metal piece the chain wraps around. The length matters for what you cut.
- Shorter Bars (10–14 inches): Good for pruning small branches and light work. They offer better control.
- Longer Bars (16–20 inches): Necessary for felling medium to large trees. Most homeowners need a 16-inch bar.
3. Safety Features
Safety is non-negotiable. Always check for these:
- Chain Brake: This stops the chain instantly if the saw kicks back. This is a must-have feature.
- Chain Catcher: This small piece catches a broken or derailed chain.
- Anti-Vibration System: This reduces shaking, making the saw easier to hold for long periods.
Important Materials That Matter
The materials used affect how long your chainsaw lasts and how it performs.
Engine Components
Gas engines need strong parts. Aluminum or magnesium casings resist wear better than plastic. High-quality steel is used for the crankshaft.
Bar Material
Look for bars made from tough, heat-treated steel. Some bars are made with a special nose sprocket that reduces friction, making cutting smoother.
Chain Quality
A good chain stays sharp longer. Look for chains made from hardened chrome steel. Dull chains make your work much harder.
Factors That Improve or Reduce Quality
Not all chainsaws cut the same, even if they look similar.
Quality Boosters
- Tool-Less Chain Tensioning: This feature lets you tighten the chain without needing a screwdriver or wrench. It significantly speeds up maintenance.
- Automatic Oiling: The saw should automatically drip oil onto the bar and chain while running. This keeps the parts cool and working well.
- Easy Start Systems (Gas Models): A reduced-resistance starter spring makes pulling the cord much easier.
Quality Reducers
- Excessive Plastic: Too much plastic housing on a powerful saw can lead to overheating or breaking under stress.
- Poor Balance: A poorly balanced saw feels heavy on one end. This causes operator fatigue quickly.
- Flimsy Chain Brakes: If the brake mechanism feels weak or loose, it might not stop fast enough in an emergency.
User Experience and Use Cases
Think about what you plan to do with the saw.
Light Use (Trimming, Small Firewood)
If you only use your saw a few times a year, a lighter electric or smaller gas model (under 40cc) works perfectly. They are easier to handle.
Medium Use (Felling Small Trees, Regular Firewood)
For regular weekend chores, you need a mid-range gas saw (40cc–55cc) or a high-power, high-Ah battery model. Comfort features like good handles become very important here.
Professional/Heavy Use
Professionals need durable, powerful gas saws (55cc+). They prioritize engine longevity and rapid refueling/maintenance access.
10 FAQ About Buying a ’20 Chainsaw’
Q: What is the most important safety feature?
A: The chain brake is the most important safety feature. It stops the chain fast during kickback.
Q: Should I buy gas or electric?
A: Buy gas if you need maximum power for large, frequent cuts. Buy electric if you prefer less noise and easy starting for smaller jobs.
Q: What does CC mean on a gas chainsaw?
A: CC stands for cubic centimeters. It measures the engine size, which tells you how much power the saw has.
Q: How long should the bar be for cutting firewood?
A: For most standard firewood cutting, a 16-inch bar gives you a good mix of power and maneuverability.
Q: What is “kickback”?
A: Kickback happens when the tip of the bar hits something hard, causing the saw to suddenly jump up and back toward you.
Q: How often should I sharpen the chain?
A: You should check the chain sharpness often. If you notice you have to push the saw instead of letting the saw do the work, it needs sharpening.
Q: Does bar oil come with the saw?
A: Usually, the saw comes with a small bottle of engine fuel mix, but bar and chain oil must be bought separately. It is necessary for operation.
Q: What is anti-vibration?
A: Anti-vibration systems use rubber mounts to absorb the shaking from the engine, protecting your hands and arms.
Q: How do I know if the battery life is good?
A: Look for a battery capacity listed in Amp-hours (Ah). Higher Ah means the battery lasts longer before needing a recharge.
Q: Can I use a long bar on a small saw?
A: You should not. Using a bar that is too long makes the small engine work too hard, which can damage the saw quickly.
