Husqvarna 450 18-inch 50.2cc 2-Cycle Gas Chainsaw Review

When it comes to a quality chainsaw, sometimes your projects require extra power and a more professional quality power tool.

Lightweight, small chainsaws are great for small jobs, but what about when you need to tackle something larger, or you just need the power? A chainsaw that combines professional quality, an affordable price, and ease of use is my ultimate chainsaw.

Quick Summary


Plenty of power for homeowners with land to care for. Very easy to start for a gas chainsaw, and won't vibrate like crazy - so can be used by people of all ages. It's a bit pricey, but the general consensus is that it's worth it.  

Things to consider before buying a gas-powered chainsaw

Gas-powered chainsaws tend to provide more power and torque than comparable electric chainsaws. It is hard to duplicate the power of a durable, powerful engine that has tons of added features that can easily compete with electric models.

When considering a gas-powered chainsaw, it is important to consider the amount of power and cutting radius you need. It helps to have some idea of what you intend to use the saw for as it will help you determine how powerful and how large of a saw is necessary for the project.

It is also helpful to look for gas-powered chainsaws that combine power with efficiency. There are gas-powered chainsaws on the market that guzzle fuel and put out noxious, unpleasant emissions. It is recommended to look for more fuel-efficient brands and those that have added emissions protection. With ever increasingly strict environmental standards, this can end up being a very important sticking point.

Husqvarna 450 18-inch 50.2cc Gas Chainsaw

Husqvarna is a well-known and well-trusted manufacturer of various lawn and garden tools ranging from lawnmowers to chainsaws. The 450 line of chainsaws offers a combination of efficiency and power, making it one of my top choices for a gas-powered chainsaw.

The 450 offers exceptional power and a wide, 18” cutting radius, making it a great saw for a variety of projects large and small. Check out the job it does on these ash trees:

The X-Torq patented technology reduces emissions and increases fuel efficiency, while also adding to the stability of the saw. It allows for less vibration, which makes the saw easier to wield and produces a cleaner, more efficient cut.


  • Lightweight - perfect balance between weight and power

  • Reduced emissions - environmentally friendly

  • LowVib technology which reduces vibration


  • Instruction manual is not user friendly

  • Not enough power for prolonged usage

Features and benefits

Husqvarna's 450 line comes with a variety of features and added technologies that bridges the gap between gas and electric chainsaws. It has features designed to reduce vibrations, fuel consumption, and emissions, which are often a big selling points for electric chainsaws.

Low emissions high-efficiency engine

With a powerful 3.2 horsepower engine, you might not think that would make for the most efficient engine, but the X-Torq technology is designed to reduce emissions and increase efficiency, lowering fuel consumption.

With the X-Torq technology, emissions are reduced by upwards of 60%. You also use about 30% less fuel, which reduces the operating costs of this powerful saw, in addition to the harmful emissions many comparable saws emit.

Durable engine

The engine is designed with a 3-piece crankshaft which provides a more durable engine that can stand up to the daily wear and tear you put it through.

Centrifugal air-cleaning system

A clogged air filter is a big hassle; it requires you to stop, take the saw apart, and clean or replace the filter. With some saws, you can end up doing this with almost every use. The 450 has a centrifugal air cleaning system that helps keep debris from reaching the filter. This increases its performance as well as reduces the amount of maintenance required.

Smart start

One of the biggest complaints with gas-powered chainsaws is that they can be difficult to start. Pull starts require a lot of strength and a degree of luck. The cord in the 450 model has reduced resistance, making it far easier to start with ease, without a bunch of trial and error.

The choke/stop control makes the engine far more likely to start up the first time and you run a far smaller risk of flooding the engine than with models that do not utilize this starter mechanism.

LowVib technology

The LowVib technology dramatically helps reduce vibration, making for cleaner cutting lines. Vibration is also known to tire out the user far faster than models that have less vibration. With the 450, you get the benefits of reduced vibration making it much less of a strain to operate the saw.


The handle is asymmetrical, allowing for a better and more precise grip.

Low kickback

The 450 has an inertia activate chain brake that is designed to improve the safety of the saw. With this feature, there is a lower risk of injury that is associated with the strong kickback that some gas-powered chainsaws have.

Top Alternatives

While the 450 is an excellent model, it is a little on the pricey side, which can make it prohibitive for some budgets.

There are quality alternatives that have similar features, but at a smaller price tag. These saws do not have all the features and benefits of the 450 model, but they may still be perfectly suited for your needs as well as your budget.

The ultimate decision on which saw is the best value will need to take into consideration your requirements as well as budget.

Makita EA3201S35B 32cc 14-inch Chainsaw

This is another great gas-powered option that might be a good choice for someone who doesn't need quite the level of power or cutting radius as the Husqvarna we reviewed.

At about half the price, this saw also has an easy-start function that makes it easier to start than traditional pull cords. The engine is not as powerful and the cutting radius is not as wide as the Husqvarna, but it is known for being lightweight with enough power for most basic yard and cutting jobs.

Surpass 20" Gas Chainsaw

This is another high-quality gas powered option that has a smaller price tag than the Husqvarna we reviewed earlier in this piece.

This saw has a more powerful engine and a wider cutting radius than the other saws we have reviewed here. It has a powerful engine that has technology that keeps the engine cool and running optimally. O

ne of the biggest differences between this model and the Husqvarna is that it does not come with nearly the number of special features that make the tool easier to wield.


The best kind of chainsaw, in my humble opinion, is one that wonderfully blends power, performance, and ease of use. There are features of the 450 that make this one of my favorite chainsaws.

The X-Torq technology reduces vibrations, emissions, and fuel consumption. The LowVib technology makes the saw easier to wield and manage. The heavy-duty motor and all metal aspects make it durable and long-lasting.
