When Was The Gas Powered Chainsaw Invented [Some COOL Facts]

Stihl patented the first gas-powered chainsaw in 1926, but the official manufacturing date was 1927. The Dolmar Chainsaw company began replicating the gas-powered chain saws for market production.

These gas-powered chainsaws are equipped with more power than electric units. It was maximized in the 1930s and was deployed to meet the wood and timber demand in World War II.

As time progressed, alongside the industrial revolution, the chain saw design also improved and was replaced with aluminum and steel components to achieve lighter weight.

Sometimes, when you intend to choose a chainsaw for massive, heavily loaded jobs regularly, you’ll have to advance from just a 14- or 16-inch chainsaw.

A 20-inch chainsaw is suitable for producing across-diameter logs and branches and can be a handy tool for anybody who lives on a ranch or in the county.

Of course, if you don’t know how to select the right chainsaw for your needs, so much force throughout your chainsaw can make it more challenging to handle.

Some COOL Facts About Chainsaws You Need to Know

Top Best 20-inch Chainsaws on the Market

Here are the models of the best 20-inch chainsaws on the market. Please look at our in-depth evaluations to see which saws consumers think are the best in the business for any project you’re working on.

1. Husqvarna 460 Rancher 20-in Gas Chainsaw

Husqvarna keeps producing exceptionally reliable and innovative tools, which should be no surprise.

A robust 60.3 cc engine powers the 460 Rancher’s massive 9000 RPM blade speed, and with 3.4 Nm of engine power behind the 20-inch bar, this chainsaw could handle any job you throw at it.

An automatic chain oiler aids in the delivery of lubricating oil to the bar and chain, allowing for uninterrupted cutting.

Inertia-operated chain brakes, a swift side-mounted chain over-tightening system, a speedy air purifier for easy cleanup, and a patented technology LowVib motion reduction framework round out the 460 Rancher’s long list of features.

2. Echo CS-590 20 Timber Wolf Chainsaw

 

The Echo CS-590 Timber Wolf is our runner-up throughout the race for the ideal 20-inch chainsaw.

It’s an effective chainsaw that almost matches the Husqvarna 460 in nearly every way — except for a pair of glaring issues that hold it back.

Because of a well-designed decompression valve, the CS-590’s two-stroke motor (typically) begins quickly, including on freezing-cold days. The industrial chain will see you through several months of work. It is ideal firewood saw because of its ability to run flawlessly through cut after cut.

The CS-590 is non-returnable and does not come with a money-back guarantee. The blade guard’s plastic is thin and brittle, and it isn’t worth sacrificing safety. It’s also simple for the engine to flood, so initially, proceed with caution.

Highlighted Features

Engine Displacement (cc)	59.8

3. Poulan Pro-20″ 50cc 2-Cycle Gas Chainsaw

Poulan Pro, a well-known sub-brand of Husqvarna, provides formidable resources at a fraction of the price of one’s orange parent. Poulan’s PR5020 20-inch chainsaw model is a remarkably lightweight option to other big chainsaws, which still packs a decisive blow.

The PR5020’s 50cc engine places it near the bottom of the power spectrum for 20-inch chainsaws. However, a patented OxyPower engine technology that generates more power from less fuel can easily stay competitive with more giant engine chainsaws.

The only real disadvantage? The PR5020 is heavy to use. A weight of 17 pounds can easily cause fatigue, mainly in the hands and shoulders of even the strongest laborers. We’re glad its reducing vibration system works well because otherwise, the added weight could’ve been a deal-breaker.

Highlighted Features

Item Dimensions LxWxH	12 x 16 x 11.8 inches
Brand	Poulan Pro
Power Source	Gas Powered
Item Weight	17 Pounds
Cylinder displacement	51 cm³

Criteria To Check When Buying A 20-Inch Chainsaw

Budget

You can spend hundreds of dollars on an all-singing, all-dancing saw, but it’s pointless when you’re not going to use that to its full potential. After all, if you purchased a Ferrari, you wouldn’t limit your pace to 30 mph! Most of the finest chainsaws, particularly for the occasional user, can be purchased for less than $200.

Engine Power And Size

Engine size for gasoline-powered saws is evaluated in cubic centimeters. The higher the CC, the more Chainsaw-engine power is produced, but the trade-off is increased weight.

Engines can be as small as 23cc and as large as 120cc, but most property owners will be perfectly alright with something between 30cc and 45cc.

The power of an electric chainsaw motor is measured in Amps. An 8 amp engine will generate approximately 1.3 bhp, while a 15 amp motor will generate about 2.4 bhp.

Durability

Stihl, Husqvarna, and Echo are mostly just several of the identities that stand out in quality. However, don’t be a brand enslaved person. Many companies are now producing excellent saws, and indeed the leading brands produce the occasional ‘turkey.’

The review sites will warn you of any issues with quality and dependability and will figure you in the path of good saws while trying to steer you away from bad.

Handling And Maneuverability

You can consider your age and general physical fitness. You might be capable of lifting an 11-pound weight with ease. However, using an 11lb saw for several minutes is one thing.

Moreover, using it continuously over 30 minutes when weariness sets in is quite another. As a result, you risk getting a mishap when you choose a saw that you can’t handle properly.

Safety Features

There are numerous ways to get injured while using a saw. While the safety measures included in today’s machines will help, they can never totally protect you from injury and accident.

You must study the manufacturer’s operating handbook whether there is anything you must do.

Don’t just skim through it; read it well and pay attention to what it says. Even if you’ve used a saw before, there are differences in the characteristics and features of different kinds and models that you should be aware of.

Frequently Asked Questions (FAQs):

Can I Use My Chainsaw In The Rain?

When you use your chainsaw throughout the rain, you’re more likely to get an electrical shock, especially if it’s corded. Even though you’re using a wireless chainsaw, cutting in the shower puts your blades at risk of rusting.

How Big Of A Tree Can A 20 Inch Chainsaw Cut?

An 18-inch-diameter tree would be taken down with a 20-inch chainsaw.

What Should You Avoid With A Chainsaw?

When using a chainsaw, be careful not to overheat it. Cutting into the dirt can weaken the cutters and wear the chain and bar. Instead of using the required lubrication, load the Chain Lubrication Reservoir with old motor oil. A chain that is either loose or too tight eats out the driving gear and the chain and bar.

You might burn out the centrifugal gear in seconds if you push the throttle aggressively when the brake is engaged.

Wait and ensure the kickback brake isn’t upon whether the chain doesn’t rotate when you squeeze the trigger. It’s better to stop and sharpen the razor when it starts creating sawdust instead of chips.

Regular engine oil will combust with it, but a 2-cycle lubricant is intended for lubricating and igniting with the gas.

If the air filter is clogged, don’t use your chainsaw, allowing dirt and dust to enter the combustion chamber. Filters are inexpensive, but just a new chain saw motor is not.

How Many CC Chainsaw Do I Need?

Chainsaw engines are distinguished by their power, measured in cubic centimeters (cc). A 65-cc engine produces additional capacity, convenient for cutting through thorny trees. Meanwhile, smaller engines with only 31 cc seem to be everything you want to cut your hedges or cut thin wood boards.

When selecting the best chainsaw, consider the engine power of the tool concerning the primary duty for which it will be used.

What Work Am I Using A Chainsaw For?

Selecting the perfect chainsaw comes down to what you want to do with it in the end. Your job will determine the sort of chainsaw you buy.

Heavy work: If you’ll be down trees for several hours, invest in a professional chainsaw with a 65-110 cc engine and a 16- to the 20-inch guide bar.

For moderate work, slashing logs for firewood require only a 55 cc engine and a 16-inch guide bar. Hence, you may pick a chainsaw with a 31 to 34 cc engine if you wish to prune hedges or branches. A pole saw, which includes a retractable pole, a tiny motor, and an eight-inch bar, is also available.
