Patrick McMann


Husqvarna chainsaws are a rage among professional users due to their longer runtimes and large-capacity fuel tanks. The company is known for producing powerful and efficient tools and has an excellent reputation for including safety features in its cutting machines.

Among their best medium-sized power tools are Husqvarna 450 and 455 Rancher chainsaws. If you want to purchase one of them and don’t know which to choose, I’ll help you in making this decision. 

In this article, I’ll share the differences between each chainsaw model and their similarities and drawbacks as well. So, let’s get on with the detailed comparison of Husqvarna 450 vs 455 Rancher.

Husqvarna 450 Vs. 455 Rancher – Which to Choose?

The Husqvarna 450 Rancher is a lightweight mid-range gas-powered chainsaw with a 3.2 hp engine, an 18-inch bar, and ergonomic handles. On the other hand, the Husqvarna 455 Rancher is a heavyweight mid-range gas-powered chainsaw featuring a 3.5 hp engine and 20-inch bar. Both cutting machines are ideal for homeowners and commercial users. 

However, their differences don’t only lie in their engines and bar lengths. There are also differences in their power and functionality as well, which I’ll discuss below. So when buying one of them, you can make an informed decision. Here is a detailed comparison of Husqvarna 450 and 455:

1. Size

The Husqvarna 450 Rancher weighs around 11.33 lbs excluding the weight of cutting equipment. It features 11.5 inches in height, 8.9 width, and 16 inches in length. In comparison, the 455 model is heavy, weighing 13.2 lbs, excluding the weight of cutting equipment. It comes with a 41 inches height, 9.5 inches width, and 20 inches length.

2. Engine

The Husqvarna 450 and 455 both boast the proprietary X-TORQ 2-stroke engine, which uses a 50:1 gas and oil mixture. However, both have different engine sizes and power outputs. The 450 has a 50cc X-Torq engine that produces 3.2 hp with a 3.06 cu. inch cylinder displacement. 

While the 455 Rancher cc is 55.5, which means it has a bigger and more powerful X-Torq engine. The large size and power of the engine ensures a slightly larger displacement, 3.5 hp, and a 3.4 cu. inch cylinder displacement. 

Although both 450 and 455 run with a 9000 rpm maximum power speed, the 455 can reach a maximum engine speed of 13,300 rpm. This is an advantage over the 450 when performing heavy-duty cutting tasks.

3. Bar Length

The bar length of a chainsaw determines how deeply and quickly the tool can cut through the wood. Longer bars are ideal for felling trees and cutting thick branches, while shorter ones are good for limbing and pruning. 

In the case of Husqvarna 450 and 455 models, the former comes with an 18-inch bar while the latter has a 20-inch bar. However, the company also offers the 450 model with a pre-installed 20-inch bar. 

The minimum and maximum bar length of the 450 chainsaw supports is 13 and 20 inches. While the 455 model supports a minimum of 13 inches and a maximum of 24-inch bar length. The support for a 24-inch bar length is excellent for felling trees over 18 inches in diameter.

4. Fuel Volume and Usage

The Husqvarna 450 comes with 0.26 liters/0.55 US pint of tank volume, while the 455 supports 0.32 liters/0.7 US pint of oil volume. But as the 450 has less hp than the 455, it consumes less fuel per hour than the 455 and is more fuel efficient. So, you’ll need to refuel less compared to the 455 chainsaw.

Moreover, the 450 model comes with a transparent fuel indicator and flip-up fuel cap, which is absent in the 455. The cap is easy to open, even when facing a vacuum inside the tank. It is specifically designed to enable easy air intake and displace the vacuum by turning it a quarter of the way, effectively breaking the suction force. While the fuel indicator will help you know how much fuel is left in the tank without removing the fuel cap.

On the other hand, the 455 model comes with an adjustable and automatic oil pump to control oil flow to the bar and chain. You can use it to customize the oil flow rate according to your cutting needs, especially during heavy cutting and felling tasks.

The automatic oil pump will keep your chainsaw lubricated regardless of the chain speed. This prevents over and over and under-lubrication, wear and tear, and the engine from overheating. 

In contrast, the 450 has a fixed oil pump that dispenses the oil to the bar and chain at a constant rate and is not adjustable.

5. Cleaning and Maintenance

The Husq 450 Rancher comes with a snap-lock cylinder cover allowing easy cleaning and maintenance. In many chainsaws, removing the cover is a lot of hassle if you want to access the spark plug or its gap, cylinder, or air filter. 

But in 450, the snap cover allows easy accessibility if you want to access the components inside for cleaning or replacement purposes. You can easily remove the cover by popping the snap-locks on each side without needing any tool. However, this feature is not present in the 455 model.

6. Price

When it comes to the price tag of Husqvarna 450 and 455 Rancher chainsaws, the former costs $359.99, while the latter is more expensive at $423.99. However, the $100+ price difference between both models doesn’t come as a surprise, as the 455 model comes with advanced features and ergonomics.

Note: Prices may vary depending upon the marketplaces you choose to purchase the chainsaw models.

Similarities Between the Husqvarna 450 and 455 Rancher 

Similar to the differences between Husqvarna 450 and 455 Rancher, both models share many identical features. Check out the similarities between both beastly chainsaws:

1. X-TORQ Engine

Both 450 and 455 models come with a powerful Husqvarna proprietary X-TORQ engine which is fuel efficient by up to 20% and reduces emissions by 60%

In addition, the X-TORQ technology boosts cutting power by increasing torque over a wide rpm range. This means you’ll get maximum cutting power at various speeds.

2. Starter Features

The Smart Starter system also allows for a fast start without minimum fuss in the 450 and 455 models. These cutting machines also have separate choke/stop controls to prevent accidental engine flooding. When you pull the choke, the stop switch resets automatically. 

The choke function increases fuel in the carburetor, while the stop switch shuts the engine off. Both functions work in tandem to save time by providing a quick start and shut-off. There’s also a decompression valve present in both 450 and 455 that reduces the cranking effort when starting the chainsaws.

3. Vibration Control

Chainsaws are usually quite uncomfortable to use because they vibrate a lot. But the Husqvarna 450 and 455 Rancher features a LowVib technology to reduce vibration by placing dampeners between the engine and chassis. So, it’s way more comfortable to hold the machine even during long cutting tasks.

4. Air Cleaning System

Starting a chainsaw after a long time can be challenging. But the Husqvarna 450 and 455 Rancher models come with Air Purge technology that removes unwanted air from the fuel system and carburetor. This feature makes it easy for the cutting machine to start even when it has been sitting for a long time. 

In addition, the 450 and 455 are equipped with a centrifugal air cleaning system that releases large dirt particles before the air filter can trap them. This prevents the air filter from getting clogged, thus requiring less frequent cleaning. 

Both cutting machines also come with a quick-release filter that allows for easy cleaning and replacement. 

5. Chain Tensioning System

With both 450 and 455 models, you won’t have to stop the cutting tools to adjust the chain tension. These chainsaws come with a tensioning system mounted on the side of the crankcase, making for a quick adjustment.

6. Reduced Oil Consumption

The Husqvarna 450 and 455 Rancher are energy-efficient models when it comes to oil consumption. When the engine is idle, the oil pump disengages to reduce oil flow. In addition, both models are CARB-compliant, which means they meet the emission standards set by California Air Resources Board.

7. Increased Felling Precision

If you’re a homeowner or a professional tree feller or even an arborist, the Husqvarna 450 and 455 will help you cut trees and limbs precisely. Both models have etched felling marks to ensure the trees don’t fall in the wrong direction.

8. Kickback Safety Feature

As a chainsaw operator, you already know that accidents like kickbacks can happen when operating the cutting tool. But that’s not the case with Husqvarna 450 and 455 Rancher. Both models come with an inertia-activated chain brake that stops the chain rotation as soon as it detects kickback.

9. Durable Crankshaft

Both 450 and 455 chainsaws come with a three-piece crankshaft that is durable enough to withstand the most demanding conditions. It also ensures the cutting machine runs smoothly during heavy cutting tasks and reduces wear and tear on the engine.

10. X-Cut Chain

The X-Cut chain used in Husqvarna cutting machines is its proprietary chain that has been manufactured and vigorously tested over two years in the company’s lab. Both the 450 and 455 Rancher models carry this durable chain, which can withstand various types of cutting, including heavy-duty cutting jobs.

11. Warranty

Like all Husqvarna power tools, the 450 and 455 Rancher models also have a 2-year warranty. They also have an EPA 2 certification, which means they emit significantly fewer pollutants and offer improved fuel efficiency and longer engine life.

Moving forwards, I’ve compiled a list of pros and cons of Husqvarna 450 and 455 Rancher chainsaws. So you can know clearly which model is for you and which is not suitable for your cutting needs and preferences.

Frequently Asked Questions

What bar size can you use in Husqvarna 450 Rancher?

You can use a minimum of 13-inch bar and a maximum of 20-inch bar in the 450 Rancher model. But it comes with a standard 18-inch bar. However, you can change the bar size to a different one if required.

Is the Husqvarna 450 Rancher chainsaw easy to start and stop?

Regarding starting and stopping, Husqvarna has taken measures to ensure the 450 Rancher is easy to start in various environmental conditions, whether cold or warm. 

The company has incorporated features such as an air purge bulb, a combined choke/stop control, and Smart Start Technology. These features work together to minimize resistance and simplify the starting process.

What’s the difference between Husqvarna 450 and 450 Rancher?

When comparing the Husqvarna 450 and 450 Rancher models, the most significant difference lies in the starting mechanism. With the regular Husqvarna 450, the stop switch does not revert to its original position after stopping the machine, which may require additional steps for restarting.

Is the Husqvarna 455 heavy?

The Husqvarna 455 Rancher weighs 13.2 lbs (5.9-6 kg) without any cutting equipment attached. This weight is considered reasonable for a heavy-duty chainsaw. 

However, the same weight can become challenging when performing tasks like limbing. This is because the cutting machine is continuously used for extended periods in limbing, making it quite heavy and potentially fatiguing for the user.

Is the Husqvarna 455 Rancher CARB compliant?

Yes, the Husqvarna 455 Rancher is CARB-compliant. It comes with the proprietary X-TORQ engine by Husqvarna, specifically designed to reduce emissions by 60% and reduce oil consumption by 20%.

Husqvarna 450 vs 455 Rancher: Final Verdict

Hopefully, now you know everything there is to know about the differences between both Husqvarna 450 and 455 Rancher chainsaws. If you are a heavy chainsaw user and perform heavy-duty cutting and tree felling, the 455 will be perfect for your needs. 

But you must have great upper body strength to hold it for prolonged periods as it’s a heavy tool. On the contrary, if you want a cutting machine for personal or home cutting tasks like limbing and pruning, the 450 Rancher will serve you best. 

Both are great tools independently as they are CARB-compliant and have reduced oil consumption and safety features to prevent kickbacks. But before buying one of them, consider your preferences, your cutting needs, and most importantly, your budget.
