Best 20 Inch Chainsaw Reviews With Comparison & Buying Guide

Chainsaws come in various sizes from small electric models to large gas-powered chainsaws. The size to buy depends on what you need a chainsaw for. If you just want something for pruning a small electric chainsaw will do just fine.

But when you have to tackle heavy-duty tasks such as felling trees and cutting firewood, you need something with a little bit more oomph. A 20-inch chainsaw becomes an invaluable tool for felling trees and cutting wood.

This brings us to the all-important question, which is the best 20-inch chainsaw? We decided to test a variety of 20-inch chainsaws with the aim of compiling a list of the best. We narrowed down to the following five.

Of the five, the Echo CS-590 Timberwolf was our top pick. This chainsaw is powerful and can accept chains of between 16 and 27 inches. Thus you can use it for a wide variety of tasks.

Second on our list is the Husqvarna 20 Inch 455 Rancher Gas Chainsaw, which is also powerful and can handle a multitude of cutting tasks. However, our top two picks should not dissuade you from reviewing the other options on the list.

But what got us interested in this chainsaw was its versatility. It can accommodate chains of 16 inches to 27 inches. This means you can use it for almost anything.

The Husqvarna is not a small chainsaw, and neither is it lightweight. Some people will find it a bit too bulky. However, if you need something that can handle felling trees, this is the right chainsaw.

A powerful 55.5 cc 2-stroke engine powers it. This is the kind of engine you find on chainsaws designed for felling trees. With such a powerful engine, its emissions must be a nightmare to the environment, right?

Wrong, with the use of x-torq technology, this chainsaw has minimal emissions. More importantly, this chainsaw has low vibrations which means you can use it for longer.

Factors to consider when buying a 20-inch chainsaw

So what are some of the things you should consider when shopping for a 20-inch chainsaw? The most important are;


While gas-powered chainsaws are powerful, their power output varies. Some are more powerful than others. The amount of power needed will depend on the kind of tasks you will be handling. A 50 cc engine will be sufficient for felling large trees.

The more powerful the engine, the more heavy-duty tasks it can handle.

Anti-vibration system

Gas-powered chainsaws are large, bulky and as already stated powerful. As such, they can cause fatigue when used for long periods. To minimize fatigue, the best chainsaws often feature anti-vibration systems.

This system absorbs the vibrations caused by the chainsaw as it cuts through wood. Anti-vibration systems will come in handy, especially if you have a lot of cutting to do.

Spring-assist start

Starting a gas-powered chainsaw is done by pulling a cord. The amount of energy required to pull this cord varies from a chainsaw to chainsaw. Ultimately, though it can take some time. And here is where a spring-assist start comes in handy.

This assist reduces the force required to start a gas-powered chainsaw. As such, for home use consider a chainsaw with a spring-assist start. Such a chainsaw will only need 2-3 pulls of the cord to start.

Chain brake

One thing you have to watch out for when using a chainsaw is kickback. This happens when the chain comes in contact with something hard like a rock. This causes it to jerk backward and can cause injuries.

A chain brake stops this by shutting off the machine when there is a violent backward push by the chainsaw. This is an important safety feature to have in a chainsaw meant for home use.


It is essential to ensure the chain is well tensioned. To do this, you need to be able to adjust the tensioning of your chainsaw easily. Having a side-tensioning that allows you to tension the chain without removing the cover is excellent.

Frequently Asked Questions

Can I change my chainsaw chain?

In most chainsaws, you can swap out the chain and bar for another, on condition that the parts match. It is essential to check what size chain and bar your chainsaw can accommodate before swapping out the default chain and bar.

Why do chainsaw chains stretch?

One of the major reasons why a chain stretches is if it’s not getting enough oil. Another is when you have a worn-out sprocket.

Can my chainsaw overheat?

Yes, chainsaws do overheat especially during the summer months. Proper maintenance of your gas-powered chainsaw is therefore essential.


20-inch chainsaws are designed for heavy-duty work. They are bigger and bulkier than an average 16 or 18-inch chainsaw. Most in this category are gas-powered due to the longer chain and bar.

The best 20-inch chainsaw is determined by how well it runs and can cut down larger trees or logs.
