20-inch Chainsaws Buying Guide

When shopping for a 20-inch chainsaw, there are several factors to consider. Here are some key points to keep in mind:

Power source: Gas-powered chainsaws are usually more powerful, but they’re noisy, heavy, and require regular maintenance.

Electric chainsaws are quieter, lighter, and simpler to maintain, but they may not have as much power or run time as gas-powered ones. On the other hand, they are less demanding.

Engine size: The engine size of a chainsaw is usually measured in cubic centimeters (cc).

Larger engines typically have more power, but they may also be heavier and more expensive.

For a 20-inch chainsaw, an engine size of around 50cc to 60-cc is generally sufficient for most tasks.

Bar length: The bar length of a chainsaw is the length of the metal guide bar that the chain runs along.

A longer bar can reach further, but it may also be heavier and more difficult to maneuver.

A 20-inch bar is a good all-purpose size for most tasks.

Chain type: Chainsaws come in three chain types—full full-chisel, semi-chisel, and low-profile.

Full Chisel chains are for cutting through hardwood such as oak. Semi-chisel chains are for cutting softwood like pine.

Low Profile chains are the best for beginner chainsaw users and are less likely to incur kickback during use.

Safety features: Look for a chainsaw with built-in safety features, such as a hand guard, chain brake, and automatic chain oiler.

These features can help prevent accidents and extend the life of the chainsaw.

Price: Chainsaws can range from around $150 to $200. Consider your budget and how often you plan to use the chainsaw when deciding on a price point.

Brand: Consider the reputation and reliability of different brands when shopping for a chainsaw.

Look for reviews and ratings online or ask for recommendations from friends or professionals in the field.

The main benefit of a 20-inch chainsaw over a 16-inch chainsaw is that the 20-inch chainsaw is more powerful.

20-inch chainsaws will typically run longer before needing to be sharpened than mini chainsaws.

Usually, the 20-inch chainsaw is more expensive than a mini chainsaw, but the increased power and longer run time make up for the increased cost.

We’ve put together a list of the best 20-inch chainsaws based on customer reviews, expert opinions, and tests of how well they work so you can make an informed choice.

Whether you are a professional logger or a casual woodcutter, these chainsaws will get the job done efficiently and safely.
