Our 10 Best 20-inch Chainsaw Reviews:

Here are the detailed reviews on top 20-inch gas and electric chainsaws-

1. Husqvarna 20” 455 Rancher Gas Chainsaw

To kick off this review is the Husqvarna 20 Inch 455 rancher gas chainsaw. This chainsaw is a decent option for landowners or homeowners who don’t need a pro-level saw. It comes equipped with a powerful 2-cycle 55.5cc X-Torq® 3.5 hp engine that produces excellent power while consuming less fuel with reduced emission levels. It starts easily owing to its Smart Start® system. Compared to its predecessor, the 450 rancher, this chainsaw has more power but comes equipped with a smaller fuel tank.

The Husqvarna 20 Inch 455 rancher gas chainsaw uses a 20” bar and chain for all its cutting activities. However, the chain that comes with it is a safety chain that offers safety at the cost of its cutting efficiency. Whether you are new to chainsawing or not, you should know that it’s the bar and chain that determine if a chainsaw can go through a large piece of wood in one pass.

If you aren’t new to handling chainsaws, we advise you to replace the equipped chain with a new chain, Oregon, or a Woodlawn Pro for a more powerful cutting experience. If you are a novice, you should understand how to use the chainsaw before changing the chain. However, safety is provided with the equipped inertia-activated chain brake, which stops the chain dead in its track once engaged.

There’s a side-mounted chain tensioner that enables you to adjust the chain tension at any time, even while working. Know that too much tension will cause the chain to stretch or the bar to creep. And if the chain is too loose, the clutch will allow the chain to run while idling. To prevent these from happening, ensure there’s enough slack in the chain to move the chain about 5/16″ from the bar at mid-span, but not enough to lift the chain completely free of the slot on the bar.

The Husqvarna 20 Inch 455 rancher gas chainsaw features an automatic oiler that is supposed to ensure the bar and chain are lubricated always. But, it doesn’t supply sufficient lubrication, which results in chain and bar wear. This chainsaw may leak oil due to one reason or the other. However, to prevent it from leaking oil, when you are done using it open the oil fill cap and release the pressure. Doing this will stop any oil leaks. Thanks to the quick-release air filter, carrying out maintenance is very easy. Additionally, Husqvarna includes a bar cover and a 2.6 ounces oil/fuel mix bottle in the package. However, you’d have to buy the bar and chain oil separately.

This chainsaw ergonomic handle and low vibration system make it comfortable to use for long hours. Considering the weight of the Husqvarna 20 Inch 455 rancher gas chainsaw (13.2lb), it is a bit underpowered. We say this because it has the same weight as the older version (the 460 Rancher) but less power, making it a bit lacking in the power-to-weight ratio area. Although, the 460 Rancher is more expensive. But, if you rate power output more in a chainsaw, go for it because of its higher power output.

Benefits

  • It is a powerful workhorse.
  • It is not difficult to start.
  • The engine produces enough power for various cutting operations. 
  • Comfortable to use for long hours.
  • It features a Smart Start® system technology that reduces pull force by 30%, making it easy to start.

Drawbacks

  • Poor power-to-weight ratio.
  • The equipped chain decreases cutting efficiency.
  • The auto-oiler doesn’t supply enough oil to the bar and chain, plus it is not adjustable.

2. Poulan Pro 20” PR5020 Gas Chainsaw

The Poulan Pro 20” PR5020 Gas Chainsaw is a runner-up to the Husqvarna 455 rancher gas chainsaw because of a slight difference in the engine displacement. It operates with a 50cc 2-cycle 2.8 Hp engine equipped with OxyPower technology for excellent cutting power, fuel efficiency, and fewer fumes.

For those who may not know, the Husqvarna Group is the parent company of Poulan Pro. So both the PR5020 and 455 rancher chainsaws share similarities in terms of design and functions with different names. That said, you won’t experience any issues with starting the Poulan Pro 20” PR5020 gas chainsaw because of its Effortless Pull Starting (EPS) feature that reduces pull force by 30% and the purge & integrated choke/stop controls.

However, if the gas runs dry in it and it quits, you may experience some trouble starting it back after refilling. So ensure you don’t allow the gas to run dry before you refill it. Also, prime it before each start to avoid struggling unnecessarily. With the 20” equipped bar and chain, you’ll be able to cut through tree limbs and little logs min one pass. It also includes a chain catcher and a chain brake for user safety.

Poulan Pro put in tremendous efforts when designing this PR5020 gas chainsaw to eliminate the complaint of its predecessors about the automatic chain tensioner. So, they changed the auto-tensioner back to manual adjustment and made it more durable. What this means is that you can adjust chain tensioning using a wrench. Plus, the wrench clips into the machine’s back, so it’s always on standby whenever you need to adjust the chain tension.

This Poulan Pro chainsaw ergonomic design and excellent power to weight ratio offer premium comfort and easy handling. Its oversized front and rear handles coupled with the vibration system make it super comfortable to use, especially for people with weak upper bodies. The only maintenance needed is the cleaning of the air filter and spark plug or replacements of both, which is very easy to do because of the tool-free access design. Also, it comes with a case and is backed by a Poulan Pro 2-year warranty.

Benefits

  • It has an excellent power-to-weight ratio.
  • Ergonomically designed for user comfort.
  • It comes with a case and has a Poulan Pro 2-year warranty.
  • To carry out maintenance is easy and straightforward.
  • It comes with a chain brake and a chain catcher for user safety.
  • It features an EPS technology that reduces pull force by 30, making it easy to start.

Drawbacks

  • It weighs 23.3lb, which is quite heavy for a chainsaw.
  • You may experience difficulty starting it back if the gas runs dry and it quits.

3. ECHO 20 in. CS-590 Timber Wolf Gas Chainsaw

The ECHO 20 in. timber wolf gas chainsaw is specially made for farmers, homeowners, ranchers, and lawn owners with a large expanse of land filled with trees. When compared with the other two chainsaws above, its cutting power is superior. This is not surprising because ECHO equipped it with a rugged 59.8cc professional-grade, 2-stroke engine. The engine has a digital ignition with a decompression valve that makes starting it a breeze with few pulls.

With its 20” bar and chain, it will pass through hardwood trees like oak, spruce, birch, beech, and hemlock of 30 – 36 inches in diameter in one pass. Safety is assured with the dual-post chain brake that stops the chain immediately after you activate it. However, this chainsaw runs lean right out of the box and will require some proper tuning to work at its best. If you don’t have any experience tuning a saw, meet a professional or someone with vast knowledge of tuning chainsaws.

Furthermore, the ECHO 20 in. timber wolf gas chainsaw features a large 21.8 (fl. oz.) fuel tank so it can run for hours. The fuel tank is translucent for quick fuel level checks. Engine oil is supplied to the chain constantly with the aid of the automatic, adjustable, clutch-driven oiler for reduced oil consumption and longer run time.

Maintenance is minimal thanks to the G-Force engine air Pre-Cleaner™ filter that extracts dirt and debris from the engine, allowing for long intervals between maintenance. The air filter is a two-piece filter for maximum and easy cleaning. Plus, accessing it is easy because it is a tool-less process.

This ECHO 20 in. timber wolf gas chainsaw has an oversized, ergonomic, anti vibration handle for smooth handling and user comfort. It weighs 13.2lbs ((Excl. Cutting Equipment), making it a little heavy. However, its power-to-weight ratio balances it. ECHO has a 1-year commercial warranty and a 5-year consumer warranty on it. All you have to do is log on to their website after purchasing to register your chainsaw for the warranty. 

Benefits

  • The equipped motor produces exceptional cutting power.
  • It features a digital ignition starting system with a decompression valve for easy starting with 1-3 pulls.
  • ECHO has a 1-year commercial warranty and a 5-year consumer warranty on it. 
  • It has an anti vibration handle for smooth handling.

Drawbacks 

  • It runs lean right out of the box, so it will require some proper tuning to work at its best.

4. Craftsman CMXGSAMY426S 20-Inch Gas Powered Chainsaw

Next on the list is the Craftsman CMXGSAMY426S 20-inch gas chainsaw. It is best for homeowners or ranchers advanced in age who do minor wood cutting occasionally and desire a top-notch level of handling and comfort in their chainsaws. Compared to the chainsaws already reviewed above, it produces the least power. But, its handling & comfort are of no match. If you rate power output in a chainsaw more than comfort and handling, this chainsaw is not for you. However, if you want to comfortably cut small/medium size woods or do limbing, trimming, and pruning for long hours, then it is worthy of your consideration.

This Craftsman CMXGSAMY426S 20-inch gas chainsaw comes equipped with a 46cc full-crank high output 3.3 HP engine that produces enough power to cut through wood seamlessly. Thanks to its Easy Start technology, it starts under five pulls. It may not have as much power output as the other chainsaws. But it can still do some heavy cutting thanks to the heavy-duty 20” low-kickback bar and chain that goes through wood quickly and easily. You have the aid of an inertia-activated chain brake for safety and bucking spikes for steady control.

Craftsman built it with a heavy-duty, pro-grade chassis, strong enough to withstand the rugged cutting activities with no-fault. Its full-wrap aluminum handle and its phenomenal 5-point anti-vibration system make it balanced and comfortable to operate. Plus, its power-to-weight (17.7lb) ratio is top-notch.

This chainsaw has an auto oiler for supplying oil constantly to the bar and chain. However, the oiler is not effective and may leak oil due to excess supply. The only maintenance you will be doing is cleaning or replacing the air filter and spark plug, which is simple considering there are no tools involved. When you buy this chainsaw, it comes with a durable carrying case and 2-cycle engine oil. Craftsman has a 2-year warranty on it.

Benefits

  • Handling and comfort are top-notch.
  • It features a full-wrap aluminum handle and a 5-point anti-vibration system.
  • It comes with a durable carrying case and 2-cycle engine oil.
  • It comes with a 2-year warranty.

5. Blue Max 8901 2-in-1 14-Inch/20-Inch Combination Gas Chainsaw

You may be hearing of the Blue Max brand for the first time, but this brand manufactures chainsaws that can stand up to that of popular brands like Craftsman, Poulan Pro, to mention a few. We will be reviewing one of their masterpieces, the Blue Max model 8901 2-in-1 14-inch/20-inch combination gas chainsaw. This chainsaw is in close competition with the Craftsman CMXGSAMY426S but has an edge because it’s cheaper. If you need a chainsaw to do a few cutting jobs around your yard once in a while, or as a backup to your pro-saw, then buy this chainsaw.

It functions with a 45cc high-performance Blue Max single cylinder, 2 stroke engine that delivers 35% higher performance than chainsaws with 45cc engines. This engine features a quick start (CDI) ignition system for quick starting with fewer pulls. However, right out of the box, it doesn’t start easily. But after running it for one hour or two, it becomes easy to start henceforth.

From the name, you can tell it comes with two bars and chains of different lengths (14” and 20”) to meet a wide variety of cutting applications. The chains have a 30-percent increase in chain teeth for reduced cutting time. Plus, the equipped low-kickback chain brake helps stop the chain at the nick of time to prevent accidental injury.

The Blue Max 8901 2-in-1 14-inch/20-inch combination gas chainsaw has a well-thought-out design with user comfort in mind. It features a large anti-vibration handle with slip-resistant for easy handling and maneuvering, especially for a novice. With a weight of 18.19lb, you will experience only minimal fatigue when using it for hours. To ensure cutting efficiency is at its peak, Blue Max included an auto oiler that supplies oil steady to the chain. As with all auto-oiler systems, this one isn’t so efficient too.

This Blue Max chainsaw is EPA approved. It comes with a tooth file, carb screwdriver, and tension adjustment wrench for manually adjusting the chain tension while in operation. Be informed that the required fuel mix for this chainsaw is 20:1. And to help you get the mix correctly, Blue Max included a fuel mix bottle with simple markings. One major setback with this chainsaw is that it tends to loosen while in operation. Although, this isn’t serious because all you have to do is tighten it back. But, we must say it is a bit inconvenient.

Benefits

  • It comes with two chains and bars (14” and 20”), making it multipurpose.
  • It is cheap compared to chainsaws in its category.
  • It starts with ease and has EPA approval.
