20” Chainsaw Use and Power

20-inch chainsaws, in particular, are incredibly useful tools to have. These are highly versatile due to engine power and can be used for a wide variety of jobs to save you time and money both with landscape maintenance, as well as property care. The power provided from the engine support not only a 20-inch bar and chain, which is considered a commercial size for professional sized jobs but also many smaller bar lengths as well to make them work in more compact cutting situations.

Because of the power required for a chain of this length, these saws are powered by a gas engine, generally of a 46cc engine displacement or higher. These 2 stroke engines are easy to maintain and clean, as discussed further in more detail below. Perfect for large log cutting, tree removal, firewood cutting, construction work, and log milling, a 20-inch option provides all the power you need without becoming too heavy or cumbersome to handle for long periods of time.

How Chainsaw Sizes Differ

Different sizes of chainsaw

If you are wondering about the differences in chainsaw size and what sort of jobs they can handle, it’s important to understand the large variations found in chainsaw models to see where a 20-inch saw belongs. Bar and chain lengths of a saw can vary anywhere from 10 to 59 inches and may be powered with either an electric or gas engine. Smaller options are generally used for small cutting jobs and carving and are more likely to be more widely available in both electric and gas version.

20-inch saws fall on the side of a more professional length and are usually the smallest size used commercially. But as mentioned above, they are also highly versatile, especially for homeowner use. These saws are still a bit more compact overall and easy to handle, but still, have the power to rip through some seriously heavy job loads.

Choosing A 20” Model

Consider a few things prior to purchasing a 20” chainsaw. This is a powerful tool and sometimes bigger is not always better, but the versatility of this size is often a selling point. Ask yourself the following:

What am I using my chainsaw for?

A 20-inch saw is a hefty bit of machinery power-wise, and if you aren’t planning on doing much more than cut firewood and other simple tasks, it may be too large for what you need it for. Using a saw that is too big for your job can be a safety hazard. But if you have a wide range of jobs you would like to tackle, including heavy cutting, then the ability to change out bar lengths and take advantage of its versatility may be worth considering.

Do I have experience with chainsaws?

As mentioned, this is a power saw. If you have never used a chainsaw before, or are not very adept at their use, you may want to take a quick safety course and handle larger saws so you know what to expect.

Do I know how to maintain my saw?

Just like above, if you are unable to break down and put your saw back together, you probably won’t be running it for very long since regular maintenance is a must. Knowing how to tighten your chain and adjust the carburetor if needed is also handy knowledge for keeping your saw at its best.
