The Best Gas String Trimmers in 2020

We don’t disrespect the electric string trimmer or anything, but sometimes, it just doesn’t cut it (pun not intended). Electric trimmers have come a long way in recent years, and they are able to work for an average person’s lawn, but when you have thick weeds or brush, they can struggle.

That’s why the gas powered string trimmer, also known as a weed eater, weed wacker, or brush cutter, is here to stay for now. While filling it up with gas isn’t the best for the environment, the modern gas trimmer manages to have a powerful engine without damaging the environment too much. And while a gas trimmer may be slightly more expensive in some cases, you can find some great ones for not too much.

So that’s why you should check out a gas trimmer. But there are so many to choose from. Which are the best for the job? When you need to cut some grass, you know that grass waits for no one, and you have to pick ASAP. That’s why we’re here to help.

If you’re looking for the best gas string trimmer, read on to look at our top 5 picks.

What Should I Look for When Buying a Gas String Trimmer?

Straight vs Curved

You may notice that some types of weed wacker are available in either a straight shaft or a curved shaft, and you may not have a clue as to what this entails.

Simply put, a straight shaft improves your reach. If you need to reach some weeds that are growing from the walls of your home, a straight shaft can help. Not to mention, a straight shaft is compatible with more attachments. Do you want some blades? Edgers? Clippers? Then buy a straight shaft. Finally, the straight shaft tends to be heavier duty.

A curved shaft is a weedwacker that where the shaft curves down near the end. The curved shaft is more ergonomic, which is good if you find carrying a weed wacker difficult. If you’re vertically challenged, a curved shaft is more convenient. They are also lighter and are good for light to moderate yard work.


A weedwacker spins a line around, which cuts grass, weeds, and brush. However, not all lines are equal. Some are lighter, and others are heavier. What does this mean for you? Simple. If a line is lighter, it can work well for light jobs but may fall short when you have a heavy duty task ahead of you. However, heavier lines are, well, heavier, and may not work with certain gas powered string trimmers.


The engine is what keeps the best gas string trimmers going, so of course, you need to have a good one. When you are looking for a gas powered weed eater, you may notice that they are divided into 4 cycle or 2 cycle, with some calling it a stroke instead of a cycle.

Cycles deal with fuel delivery. Simply put, a 2 cycle engine is powered by a container that is a mix of gas and oil. Meanwhile, a 4 cycle has gas and oil in their own containers.

They both have their own pros and cons. A 2 cycle is lighter, quieter, less expensive, and it’s more convenient to fuel it, but it may not be as good for heavy duty, efficient jobs. Meanwhile, the 4 cycle is the opposite of everything the 2 cycle is.

Also, starting the engine should be easy. With a gas powered string trimmer, you may have to do a little pulling, but it shouldn’t be a tough task.

Easy Start

Okay, let’s talk a little bit about starting the trimmer. A long time ago, string trimmers could be tough to start. You had to choke the engine, but not too much, and no matter how hard you pulled, it never seemed to work. Nowadays, an electric string trimmer requires none of that.

However, a gas one does. Luckily, many modern trimmers use easy start technology, which means that it should start through a couple simple pulls. No having to spend hours pulling it.

Cutting Width

The best gas string trimmers should tell you their cutting width. Depending on the trimmer, the trimmer line may cut more or less depending on how many inches wide it is. Having a larger width can be good if you want to get the job done fast. However, shorter may work better if you need to be more precise.

We should mention that even a slight difference in width can stand out. If you have a lot to cut, one that is an inch more than the competition can save you quite a bit of time.


Gas powered string trimmers can be quite loud, but some are louder than others. After all, you have an engine that has to keep running during your weed wacking journey. While no weedwacker is so quiet you can use it at midnight without waking the neighbors, some are quieter. You may not need to get any ear plugs with these.

Fuel Efficiency

Here’s another one that’s obvious. The gas powered string trimmer should preferably deliver the most power while using the least amount of fuel possible. Not only will the emissions lower, but you don’t have to fill up as much.

There are several factors that can influence fuel efficiency. For example, you may get more mileage if you put the preferred oil in the engine. You may get more if you perform maintenance every once in a while. There are several factors that can make or break this.

Anti Vibration

Even the best gas string trimmers will vibrate, but a powerful string trimmer will have some good anti-vibration properties. With that said, you may need some specialty gloves when carrying these weed eaters. The latest ones have an engine that doesn’t vibrate too much, luckily.


Some of the best gas string trimmers cost a pretty penny. You want a company that will stand by their product and not sell you any junk. A good gas powered weed eater will have a warranty of a year or more and will be able to repair it should something go wrong.


Gas string trimmers are a little more expensive than electric, but there’s one for every budget. Make sure you are purchasing a string trimmer that is right for your budget needs. With that said, you should remember that it is better to get a trimmer that’s more powerful than what you need than a trimmer that is a little underpowered for your yard.

And there you have it. These are some features to look for when you’re searching for a string trimmer. It’s a little more complicated than just looking for a machine that can cut grass.

Which Is Better: Stihl or Husqvarna Trimmer?

When it comes to the best trimmer, you have many brand options. One is the Stihl weed eater and the Husqvarna trimmer. While this is not an article about comparing trimmer brands, we suppose we could take a brief glance at these two pieces of power equipment.


Both trimmers manage to deliver a lot of power without weighing too much. However, the Husqvarna trimmer is a bit heavier. Not much, though. It is 11.11, while the Stihl is 10.6. For most people, this won’t be too much of a difference.


Both have nice handles that are easy to use, but the Stihl is a little better. This is because the Stihl handle can be adjusted through all 360 degrees.

Fuel Tank

A bigger fuel tank means a longer lasting engine. Both have sizable tanks, but the Husqvarna wins by a bit because its tank is a little bigger.

Cutting Width

The Husqvarna has a width a half inch more than Stihl’s 16.5. Even a half inch more can mean less time overall if you’re trying to take down a large area of grass.

The Engine

Both have an engine filled with power, and neither vibrate that much. They manage to have an engine that’s quiet while not sacrificing power. The Husqvarna has slightly more CCs, being 28 as opposed to Stihl’s 27.2.

Both are good, having plenty of engine power, but if you have to get just a single trimmer, we recommend the Husqvarna. It has a bit more for the price.

What String Trimmer Do Professionals Use?

If you’re a professional landscaper or property owner, you need a good string trimmer. While you don’t necessarily need something that costs thousands, you do need to be a bit more mindful of your choice.

In our article, the Honda HHT35SLTAT is probably the best for professional use. This is because it has a powerful engine that can cut through the toughest weeds, and it’s built to last. However, it’s not necessarily the string trimmer. You may find something better.

If you’re a professional, you will need one with a powerful engine that can cut through thick plants. In addition, you want to find a quieter machine that won’t disturb any neighbors. A professional string trimmer should be durable, shockproof, and be backed by a longer warranty so you can send it back should anything happen to it.

What Is the Best 4 Cycle Gas Trimmer?

A 4 cycle trimmer means that the oil and gas are separated. This means that you will have a trimmer that is a little heavier, but may be good for the toughest jobs.

In our post, we say the best one is the Honda HHT35SLTAT. This is a pricier trimmer, but it has the most power and has that 4 cycle performance you expect.

Of course, there are cheaper 4 cycle trimmers that can work well, too. It all depends on your situation and what yard type you need the trimmer for.
