Husqvarna 455 Rancher 20 in. 55 cc gas chainsaw review

Husqvarna 455
ReviewSpecificationWhere to buy
The Husqvarna 455 promises to be a groundbreaking chainsaw in the Husqvarna series, equipped with new technologies and very much improved power and performance, which should make it one of the best tools for professional woodcutters and landowners.

Let’s see if the 455 actually delivers these promises, buy comparing the pros and cons of using it.


Light and easy to use

Like most of its predecessor chainsaws in the Husqvarna series, the 455 is very easy to use. It starts with no problems and you can even start it without using the pressure valve – although it’s probably advisable that you use it for safety measures. You shouldn’t have problems starting in even in cold or hot weather conditions.

The low vibration on the 455 makes it very easy to work with it for long periods of time – you won’t feel a thing and can forget about the numb arms you generally get when using a heavier chainsaw.

As you would probably expect from a Husqvarna, the 455 is very light and this makes it very easy to maneuvre.

Good power for most uses

The Husqvarna 455 offers a fairly decent amount of power for its weight, and altitude won’t affect that. It can cut through most wood types at very high speed so it gets the job done quickly. If however the saw is shutting down from time to time, you should tighten the chain a little bit.


Chain problems

Most of the Husqvarna chainsaws have some chain problems eventually, and the 455 is no exception to that rule. If you use the chain for a longer period of time, the chain brake can lock up and you will have to remove the spring holding the brake in the locked position. If you overuse it a little bit, you will have to change the chain pretty often. So you may consider simply changing the chain from the very beginning if you know you’ll use it a lot.

Components may fail rather soon

Husqvarna chainsaws are lighter because they use plastic covers. And the plastic is one of the first things that will fail. This means that you’ll have to be extra careful with it. The choke handle for example is made out of plastic, so the trigger may break very easily.

The fuel mixture may pose some issues if the mix is not fresh gas from the tank and mixed with the oil right before filling it with the mix.

You can also expect oil to leak a lot when the chainsaw is idle, but that’s normal with a Husqvarna chainsaw.

A good investment for some!

The power and overall performance seems to be indeed improved compared to the previous chainsaws in the Husqvarna series, but some professional woodcutters will still find that it needs more adjustments to become a very useful tool. Others, on the other hand, will have their needs met by the 455, especially if they don’t have many needs.
