If you want to keep your lawn looking neat and tidy, you’re likely to need a trimmer.

These trimmers do not have a lead, so you’re not tied to a power outlet and you can enjoy superb performance with the power to make short work of your yard tasks.
Our research team reviewed 22 gas string trimmers to assess the functionality offered and how they operate in a typical yard. We’ve created a list of our top picks and our editor’s choice, the Husqvarna 129C offers a fantastic balance of powerful engine with an impressive 17 inch cutting swath and lightweight. However, we’ve also ranked other gas string trimmers at different price points to ensure a top pick for everyone.
Our team has deliberated for hours to find the best gas string trimmer. Whether you have a small yard that needs a little tidying or have a larger landscaping design that requires more precise trimming, we’ve assessed the performance and functionality of each machine, so you can have complete confidence in your purchase. First and foremost, we assessed the engine of each machine, which not only determines the power output and durability, but also impacts the weight of the machine. We’ve also looked at the trimmer line diameter and cutting swath, which impact the precision and coverage offered. However, we’ve also considered the weight of each unit and the manufacturer support offered, including the warranty. We’ve presented our findings as a simple overview table with a list of detailed reviews, but we’ve also included a buying guide to assist you in making your final purchase decision.

Things to Consider
A trimmer is an essential tool for keeping your yard neat and tidy. However, with so many different models, it can be confusing to make your purchase decision. So, here we’ve created a buying guide with the features to look for, things to consider and the answers to some common questions to help you make your final choice.
Gas string trimmer vs. electric string trimmer
The two main types of string trimmer are gas or electric. Mains operated electric models have the advantage of running on electricity, so you don’t need to worry about fueling up, you just plug them in and you’re ready to go. However, the disadvantage to this is that you need to deal with the lead. The lead can be highly awkward and is likely to get in the way as you’re trying to trim your lawn. It can not only severely limit the distance you can move, but is also potentially dangerous as you are at risk of a shock if you inadvertently trim the lead.
This is where a gas string trimmer has the edge. Gas versions don’t have a lead to worry about and they are typically far more powerful. If you start to run out of gas, you just need to simply top it up and you can keep going. While gas string trimmers tend to be a little noisier, they do offer power and mobility, making them an essential tool for all your trimming and edging needs.
Features to consider when purchasing a gas string trimmer
With so many gas string trimmers on the market, it can be tricky to choose the best one for your specific requirements. Here we’ll explore some of the key features to consider to help you narrow down the options and choose the best model.
The engine is the heart of the trimmer and the most crucial part of the machine. The engine determines not only the speed of your grass trimmer, but also its toughness.
The capacity of gas string trimmer engines is measured in ccs like a car engine, with the smallest capacity at 15cc, but they can range in size up to approximately 50cc.
While a smaller engine may use less fuel and be lighter, they will also tend to have a lower speed and output.
Another aspect of trimmer engines to consider is the number of cycles. Two-cylinder engines use a mixture of gas and oil, while four-cylinder models have different compartments for fuel and lubricant.
The choice of engine in your string trimmer needs to be carefully considered. While there are powerful smaller engine models like the Echo GT-225, many models with this size of engine will lack the power to tackle tough garden trimming. However, larger engines can also increase the weight and vibration of the machine, which can lead to getting tired faster during operation.
There are two basic choices of string line; single and double. Single line string trimmers tend to be the cheapest and easiest models to use. All of the power goes to a longer string, which means that they tend to operate at higher RPMs.
Dual lines refer to two shorter strings that are located under the shield. While these still quickly rotate, they do not operate at the same high RPM rates. This means that you’re not as likely to feel the stinging sensation of cut grass and weeds whipping at your legs as you’re using the trimmer. Dual line string trimmers also tend to more evenly cut the surface grass, creating a neater finish that can even up the look of your lawn.
The cutting swath refers to the size of the cutting path. This becomes important when you have a lot of space to cover or odd shaped areas in your yard. The cutting swath of gas string trimmers can be as small as a 10-inch radius, but there are models such as the Craftsman WS205 that has a 17-inch radius.
You will need to assess the optimum cutting swath for your yard. While it may be tempting to opt for the largest possible, if you have lots of odds shapes in your yard, you may prefer the precision of a smaller cutting swath.
The length of the trimmer shaft is a crucial factor in weight distribution and maneuverability. Longer shafts ease turning from one position to another, it will also keep the fumes at a longer distance.
Some models also feature a detachable shaft, which makes them easier to store and transport.
However, one of the most obvious things that you’re likely to notice about trimmer shafts is the shape. Some have a curved shaft, while others are straight.
Some gardening experts argue that the shaft indicates the position of your back as you’re using it. So, you’ll need to stand upright with a straight shaft, but you’ll need to bend over if you’re using a curved shaft trimmer.
Generally, curved trimmers tend to be less expensive, but they can be more challenging to use, particularly if you’re taller, as you may find that you need to stoop, which will put you at risk of a serious backache.
Handles and vibration
Another thing you need to consider is that there will be vibration with any tool equipped with an engine. Therefore, you need to ensure that your gas string trimmer needs to have a decent handle to ensure that you can comfortably handle it when it is running.
Many models are equipped with ergonomic handles, so you can easily maneuver the trimmer, but it is also a good idea to look for a model with a shoulder strap to ensure optimum balance.
Heads and attachments
Many models such as the Craftsman WS2200 are compatible with multiple heads and attachments. This increases the versatility of your trimmer as it can be used in place of multiple tools in your yard. However, if you just need a basic trimmer, it may not be worth paying a premium for this compatibility.
Since you’re likely to spend more than a few minutes trimming and edging your landscaping, you need to ensure that you choose a gas string trimmer that is a comfortable weight.
As we discussed above, the size of the engine can impact the weight of the unit, but this is not always the case. There are models with a small engine that are not lightweight. You need to choose a model that you can comfortably carry even for an extended period. You can also reduce the impact of the trimmer weight by choosing a model with a shoulder strap.
A warranty provides an assurance that a product is an excellent quality with no defects that will compromise the performance. If your product is under warranty and a fault does develop, you won’t need to face a hefty repair bill, as the manufacturer will repair or replace the item. Therefore, it is a good idea to choose a product that is supported by a decent warranty.
Whether you have a two-cycle engine that requires a mixture of gas and oil or a four-cycle engine that has separate compartments for the fuel and oil, you will need to check the manufacturer recommendations for the grade of gas that should be used. While some models may operate efficiently with ethanol 10% fuel, other models may suffer from carburetor issues if you use this type of fuel.
You’ll need to follow the manufacturer’s instructions for changing the trimmer line, but again, the best models are designed to make this process easier.
As you can see, there are some fantastic gas string trimmers on the market. From the straight shaft Craftsman WS2200 with WeedWacker head that is compatible with other accessories, to the Echo GT-225, which is supported by an impressive five-year warranty and is highly durable to cope with any rocks or garden obstacles.
However, the stand out as the best gas string trimmer has to be our editor’s choice, the Husqvarna 129C. This impressive machine has lower exhaust emissions and reduced noise output, but it is the Smart Start system which makes this machine superb. This system makes it easy to start up, so you won’t waste your energy getting the machine started and can concentrate on getting your lawn trimmed and edged.
