About The Husqvarna 4 Stroke Trimmer

So let’s get down to business:

The Husqvarna 4 Stroke 324L is is a gas trimmer with a 4-stroke engine that runs on pure gas, there is no need to mix oil and fuel.

It has a straight shaft and a dual bump feed line using a 0.095 inch diameter line.

The cool thing is:

It uses Husqvarna’s Smart Start and air purge system to remove air from the carburetor so it starts more easily. It has a Honda engine and uses the T35 Husqvarna trimmer head.

Excluding the cutting equipment it weighs in at 11.24lbs.

The Good


This really does have a lot of power.

It goes through even the thickest of weeds without any problems whatsoever and never bogs down.

If you have a large area to clear then this can get through pretty much anything in the minimum of time. It is a delight to use in that respect.

It’ll blow your mind.

A lot of this is down the the quality engine. It is not made by Husqvarna, but is a Honda GX25 engine, that is surrounded by Husqvarna shrouds.

Honda are known for their reliability and this engine runs perfectly and is also quiet and very fuel efficient.

So this is a 4-stroke engine.

Essentially that means a couple of things – it takes four steps to create power – with each step being more concentrated in comparison to a 2-stroke engine.

Think about it this way:

With four stroke engines the torque is much nearer the base of the unit meaning you barely have to apply any gas to get a good amount of power. Just above idle will provide you with plenty of power to trim.

And another benefit of 4-stroke engines?

They run purely on standard gasoline, you don’t have to mix gas and oil, which makes things a lot easier. Simply put in the gas and you are good to go.

Even better:

Also with 2-stroke engines the smell of 2-stroke gas inevitably seeps into your clothing, so you don’t have that issue easier.

This is nicely made – it is pretty much all steel and metal, with just a couple of plastic pieces. It is a quality commercial style unit with the (previously mentioned) great Honda engine detached and built onto the shaft.

And you know what?

It is also easy to assemble, start and use – there is almost no resistance on the recoil. Small details like the soft grip, adjustable handle make it really comfortable to use and elevate it above most other gas trimmers on the market.

But you’re probably wondering…

Do I have to constantly refill the string?

Well it uses a T35 Husqvarna trimmer head which is huge and holds so much string, I’d estimate maybe up to 40 or 50 foot of line, which is pretty much unparalleled and means you don’t need to stop to fill it up as much.

And one final thing:

It also edges really well.

Quite often with two stroke engines they bog down when you flip them over to edge, whereas this works flawlessly when you do so – the engine keeps purring away and you can easily and quickly tidy up your yard.

It is great!

The Not So Good

A word of warning:

The guard on this is not perfect – it doesn’t protect you from the grass you cut.

In fact the chances are that, as you will probably be using this to cut down substantially overgrown grass and weeds, you could be left covered in grass at the end of it all. It could definitely do with improvement.

What’s more:

The string is also quite close to the top of the trimmer head, and this makes cutting grass in really tight spots a little more of a problem. It isn’t a big problem, but something to be aware of.

Where the air filter cover sits with the main plastic frame is not as well protected as it should be. I had some issues with the clips breaking off – so this could be made more secure.

Also as you are not mixing fuel there is no tinge to the fluid in the fuel tank. The fuel tank is also made of solid white plastic.

My point is this:

A combination of these two factors means you have no idea how much fuel is left in the tank unless you open it and look every time. A slightly transparent fuel tank would make this a lot easier.

Price wise it is also at the higher end of the market – although there is a reason for that – namely the power and quality you get!

Great string trimmer

This really is one of the most powerful string trimmers on the market. If you have a large yard and lots of thick weeds to cut down I strongly recommend this.

It is perfect for land or commercial use, it starts easily, is well balanced, quiet considering the power and has a 4-stroke engine so no worrying about mixing oil and gas.

It literally goes through pretty much any weed or heavy grass like a hot knife through butter and you have the peace of mind of knowing it uses a top quality, ultra reliable Honda engine.

It is a bit more expensive, but you get so much for your money and it is so rewarding to feel it effortless cut through months of overgrown weeds and grass with the minimum of fuss!

  1. Hey Steve,

    I have been thinking about buying an edge trimmer. I have only used one a couple of times and it belonged to my brother. Being a lady I found the line trimmer heavy and very hard to start.
    I noticed your article mentioned that I can attach a harness to this model, so my arms and back don’t get so tired. But I still worry that it will be too hard to start and I will have wasted my money. I live on my own so I don’t have any muscular men to do this kind of thing for me.
    Will I, as a 58-year-old woman be able to start this Husqvarna 4 stroke trimmer? Your thoughts would be appreciated.

    Kind regards

    • Hi Karen, 

      I’d say you’d be able to start it, but I guess my main question is do you need a gas powered string trimmer? You could go for a battery or electric power unit if your yard isn’t too large? They are generally lighter and easier to use. 

      My Best Weed Eaters 2018 list should be a good starting point!

  2. Hi, Steve. Great review on the Husqvarna trimmer. I’ve not used a gas trimmer for my yard, but it’s pretty small. I almost wish I had a bigger yard so I could justify the trimmer, because it sounds really good. And you’re right, Honda makes great engines. And regular gas? That’s another plus. The time may come, though. I’ll recommend the Husqvarna to my friend, who has a landscaping business.

  3. I just bought mine and I brought to work at my restaurant in Colorado Springs(Amandas Fonda) sits on a river bank and I knocked all the weeds less than 30 minutes ….this is a great piece of equipment and made well.

  4. Linked your website to my desktop. Refreshing to read experience-based, objective reviews! I admit a personal bias of my own – I love the Honda engine – but I am open to new information, pro or con, and will continue to follow your columns and Q&A. Great job!
