Features of Husqvarna 450 Chainsaw:

Smart Start technology

At first in our Husqvarna 450 review, let’s discuss its Smart Start Technology. With this, you will not have to worry about the chainsaw spending an unnecessary amount of time to get started. When it comes to starting the engine, the air filter and oil pump actually greatly assist the Smart Start Technology. Having dirt and oil out of the carburetor helps for a clean and smooth operation.

Smart Start Technology reduces resistance by the coil by around 40%. The switches also make it super-efficient at restarting. The combined choke/stop button makes it easy to turn it on and off as well. One of the great things about this chainsaw is you will have most of your starting operations in a single button.

Cutting Equipment

This chainsaw is equipped with an 18-inch guide bar and chain. The chain has a 0.05” gauge, 0.325” pitch, and 72 drive links.

This chain uses narrow kerf technology, so it requires lesser power to make the same length of cut. It is a low kickback chain. The bar has a gentle curve and small nose radius that promote good cutting and help to reduce kickback. The speed of the chain is around 17 meters per second which means the 450 has plenty of cutting speed.

And as always the chain needs to be sharpened and maintained using the appropriate tools.

Few users expressed their concern about the guide bar being attached by a single nut as opposed to two on other products. There was a concern that this will not be sufficient to hold the bar in place, but there was no report of any major issue with this.

Finally, this chainsaw is versatile enough to accept various bar sizes, the recommended lengths are from 13” to 20”.

X-Torq Fuel-Saving System

A regular feature that you will see in the newer models of Husqvarna is the X-torq system. It’s no wonder as it is one of its best features. The X-torq makes the saw both fuel-efficient and eco-friendly.

It was designed to lessen emissions by up to 60%, and you will be able to decrease fuel consumption by 30%, too. With this one, you don’t need to be concern about meeting any air emission standards. Also, it makes the 3.2 horsepower more efficient.

Combine this with the high RPM, and you will have a saw that can cut trees like butter! This system also keeps your air filters free from debris and dust.

This both reduces fumes, making it last longer as you won’t need to do a lot of maintenance like other saws. To put a cherry on the top, you can also visibly see the level of fuel on your saw so more than just having a fuel-saving engine, you can also monitor it yourself.

3-Piece Crankshaft

The next thing we are going to discuss in this Husqvarna 450 review is its durability. If it is your concern, you are more than secure with this one. This saw was constructed with strong metal and hard plastic that will keep it going for a long time. You can surely leave this product alone for months or even years, and still, it will function as if it were new.

Air Injection

Its air cleaning system can be considered as one of the best of its kind. Especially, since tree cutting is all about dust, cleaning and replacing air filters can be such a hassle. The air cleaning system for this saw uses centrifugal motion to keep large dust away even before it touches the air filter.

This is done by having the air going for the carburetor ingestion pass through the starter, and this is what pushes out the debris. This feature makes maintenance limited as well as improve overall engine life. You still might have to clean the air filter though, but it’s only just taking off the cap and washing or wiping it.

Adjustable Oil Pump

Most of the modern saws these days have it so that you don’t have to manually oil your chainsaw every time. This one is no exception. It features an auto oiler that can adjust to fit whatever type of job you are doing.

Safety Features

The Husqvarna 450 rancher doesn’t fall short when it comes to operator safety. To help protect the user as well as the machine, the safety features are included:

  • Reduced kickback guide bar and low kickback chain.
  • Chain brake. This can be manually enabled by pushing the front guard-forward with the left hand. The brake will be operated by inertia in cases of severe kickback.
  • While cutting, bumper spikes on the front of the chainsaw help to provide stability.
  • Hand protection is provided from the chain as well as debris by the rear and front hand guards.
  • Should the chain slip off the bar, a chain catcher on the bottom of the chainsaw will provide protection.
  • Anti-vibration features decrease the possibility of getting conditions associated with the use of power tools, like a white finger.
  • These features will not fully protect the user. Wearing the appropriate protective clothing and correct handling of the saw will minimize the risk.

  • Excellent power
  • Good cutting ability
  • Easy to handle
  • Low vibration
  • Solid construction
  • Efficient engine
  • CARB compliant

  • Owner’s manual is a bit tricky to understand


  • What size chain and bar can be used in this model?

The 450 can take a bar length of 13 inches to 20 inches. This model comes with the maximum size that is the biggest many homeowners will ever need.

  • Is the Husqvarna 450 saw easy to start and stop?

A: Husqvarna has done everything they can to make starting as quick and simple as possible from both warm and cold. Things like an air purge bulb and a combined choke/stop control together with their own Smart Start Technology help to make sure it starts with the least fuss.

  • What does the centrifugal air cleaning system do?

A centrifugal air cleaning system means that all the air going for the carburetor ingestion passes through the starter. This pushes the large debris and dust out even before it reaches the air filter.
