The Best String Trimmer for 2023
Make your lawn an altar of beauty by removing weeds with ease in no time with the best string trimmers of the year.
Grass and weeds can quickly and easily be eliminated with the help of a gas string trimmer, also known as a weed wacker, when they grow up the side of the shed, encroach on the garden, or climb the fence. This gardening equipment is an excellent investment for any large yard or area with several obstacles, such as trees, lawn ornaments, fencing, garden beds, and tiny constructions. Light trimming in smaller yards can be done with battery-powered trimmers, but the force of gas string trimmers is better suited for chopping through thick grass, weeds, and brush.
Several aspects, including cutting breadth, shaft type, and engine size, should be taken into consideration while deciding on the best gas string trimmer for your yard. The factors listed above, as well as others, were taken into account while selecting the trimmers for this article’s testing. In this review, we will take a look at a few of the top gas string trimmer tools in the market today so you may have an idea of what you need before going shopping.

Who It's For
This string trimmer from trusted brand Ego boasts a 45-minute runtime on a single charge, with a modest 50-minute charging time. Unlike some competitors, this pick includes both the battery required and the charger at the initial buying price, which saves stress and further spending. Additionally, the aluminum shaft can be quickly and easily adjusted, making usage more comfortable for customers of any height. Constructed from materials with an IPX4 water-resistance rating, this device can handle water splashes or jets from any direction. This rating means this pick cannot be submerged and does not qualify as wholly waterproof.
Why It's Great
This pick utilizes a high-efficiency brushless motor. The benefits of this are that brushless motors allow for higher speeds and produce less noise or vibrations. Due to this higher efficiency, there is significantly less friction, and it lasts much longer. This option is also a dual-line trimmer meaning it cuts twice with each rotation. While a single-line trimmer may be easy to spool, a dual-line trimmer cuts faster and offers better performance. With an impressive cutting area of 30cm, the line used with this trimmer is 2.4mm (0.095 in). Generally, line thickness ranging from 2.4 to 3.0mm (0.12 in) will be heavy-duty enough for any garden task.
Potential Flaws
One of the features that this pick prides itself on is its patented power load technology. This automatic, press-and-go feature winds in the wire for immediate use within the trimmer. However, this feature was as swift as we had hoped during testing. On the first attempt, it worked perfectly, but subsequent attempts were more stunted and required some fiddling to get to work. Once strung properly, the trimmer worked like a dream, but the power loading was not as immediate as promised.
Other Features
This trimmer is powered by a 56V ARC Lithium battery, with a patented design that prevents your tool from overheating, allowing it to work longer at full power. Due to this careful design, these batteries boast a shelf-life of 10 years without any notable damage. These lithium batteries are fully compatible with any EGO Power product, meaning they can power your EGO hedge trimmer, lawn mower, leaf blower, and even snow blower!

Who It's For
This option is a previous model of our top pick. As such, it shares many of the same features, such as the power load technology and a brushless motor. However, this pick sports a carbon fiber shaft in place of the aluminum shaft of the ST1511T. The benefit of this is that carbon fiber lasts longer than most other materials and is typically more resistant to dents or scratches. Carbon fiber is also lighter than aluminum and offers twice as much rigidity. The downside of this is that the material is subsequently more expensive. Unlike the ST1511T, this pick has a battery life ranging from 30 to 60 minutes and requires roughly the same 50-60 minutes of charging time. Though this may be frustrating for some due to the long charging time compared to the usage time, testing proves the trimmer to be efficient enough for this pick to stay high on our list.
Why It's Great
With a 38cm (15 inch) cutting area, this pick has a slightly broader reach than its successor.
The ST1521S was the first product with power load technology, saving you time and stress by winding in your line automatically. This pick also shares the same line type and dual line design as the ST1511T, sharing the same benefits of fast cutting without the noise or fumes of other trimmers. Due to the lithium battery being included in the initial purchase and being fully compatible with all other EGO Power+ products, EGO helps you save expenses on replacement batteries which can be expensive in the long run.
Potential Flaws
The main issue brought up by testing and previous customer feedback is that this pick eats up the line faster than other options, requiring you to have more to hand. Although this option includes some replacement lines, it is not a lifetime supply. Additionally, this product is relatively heavy due to the battery placement, especially if you have a larger area to trim. To get around this, we recommend spending a little more to get yourself the shoulder strap, which helps prevent achy or strained muscles.
Other Features
Another benefit of this pick is its lifetime warranty, as EGO promises durable and reliable usage for years. Due to having service dealers nationwide, you can easily access face-to-face advice should you require it regarding diagnostic checks of your tools.

Who It's For
This option is the pick to choose if you require comfort and ease while you garden. With a handle sporting seven different positions, you can set this trimmer to whichever angle suits you best. Similarly, the head can pivot through six settings spanning 90 degrees, allowing easy reach throughout your garden. You can also trim safely around flowers or lawn ornaments without the risk of damaging them due to the spacer guard included with this trimmer.
Why It's Great
The WG170 is an entire foot longer than the previous WORX GT and promises a motor running at 7600 revolutions per min. This trimmer gets the job done immediately, boasting a full battery within 60 minutes. WORX has patented its Proprietary Command Feed system, which adds a ¼” of the line when you need it without waiting for the trimmer to feed it through automatically. By weighing less than six pounds, this trimmer is intentionally lightweight to prevent muscle strain or fatigue, making it a quality pick for elderly folk who still love to keep their garden tidy. This pick also sports two rubberized wheels, allowing for straighter, neater, and easier mowing when the trimming is complete.
Potential Flaws
Results from various tests concluded that the string included with this trimmer was not strong enough for all gardening purposes. Though perfectly fine for weeding or lighter work, we found that a thicker line was required for the power of this trimmer to demonstrate for us. This pick also suffered from the battery issue of spending more time charging it than using it. Although having batteries compatible with multiple tools from the same brand may save time and money for a loyal customer, this does not remove the time wasted when charging for hours.
Other Features
This pick markets itself as a 3-in-1 tool, and we love the easy way this trimmer changes to a wheeled edger or a powerfully nimble mini-mower. This multipurpose tool saves you money on multiple pieces of equipment, and by spinning at 7600 revs/min, this product guarantees neat, clean cuts.

Who It's For
With a cutting area of 38cm (15 inches), this pick includes a 2.03mm (0.08 in) line, making it ideal for long grasses and weeding. To keep up with competitors, this pick sports a REEL-EASY string head which offers fast reloads - less than 60 seconds - of line typically found on gas trimmers.
Why It's Great
Testing showed that this product has an average of 45-60 minutes of usage time before it requires charging. With a variable speed trigger offering total control to you, this product is at your command. The cutting width can be adjusted from 13 to 15 inches to allow for a longer run time or a wider cutting width.
Potential Flaws
The main problem experienced with this product is the missing items expected to be in the purchase. These items included a battery charger, the battery itself, and a shoulder strap. The price of this pick kept increasing without these items included in the initial purchase. With this and a disappointing lack of assistance when we reached out regarding a replacement thicker line, this pick failed to make our top three.
Other Features
As is popular among string trimmers, the battery powers many Riobi products. Several attachments are also available, offering more reach into the difficult-to-get areas of your garden. Riobi also promises a 5-year tool warranty and a 3-year battery warranty for this product.
Who This Is For
A string trimmer is best for people who need to do a lot of grass trimming and are willing to put in the effort to maintain a tool. They are also a good choice for those who need to trim grass in areas that are difficult to access with a lawn mower, such as along fences or around gardens. Gas string trimmers are generally more powerful than electric models, so they may be a better choice for thicker grass and weeds.
Electric vs gas string trimmers
There are several key differences between electric and gas string trimmers. Electric string trimmers are generally easier to use and require less maintenance than gas models. They are also quieter and produce no emissions, which makes them a more environmentally friendly choice. However, they may not have as much power as gas models and may not be able to handle thick grass and weeds as easily. They also require access to an electrical outlet or a long extension cord, which can be inconvenient if you have a large lawn or if you need to use the tool in areas that are far from an outlet.
Gas string trimmers are generally more powerful than electric models and can handle thicker grass and weeds with ease. They are also a good choice for larger lawns or for areas that are difficult to access with a lawn mower. However, they are louder and produce emissions, which can be a concern if you have close neighbors or if you are concerned about the environment. They also require regular maintenance, such as changing the oil and spark plug and keeping the fuel tank full.
Do I really need a string trimmer if I have a lawnmower already?
It is not necessary to have a trimmer in addition to a lawnmower, but a trimmer can be a useful tool to have for certain tasks. A trimmer is typically more portable and can be used to trim grass and weeds in areas that are difficult to access with a lawnmower, such as along fences, around garden beds, and under bushes. It can also be used to cut down tall grass and weeds that may not be evenly distributed across the lawn. If you have a lot of these types of areas on your property, a trimmer can be a useful tool to have in addition to a lawnmower.
Curved shaft vs straight shaft
A curved-shaft trimmer has a shaft that is bent in an arc shape. This makes the trimmer shorter and more compact, which can make it easier to handle and maneuver. Curved-shaft trimmers are generally lighter in weight and less expensive than straight-shaft trimmers, making them a good choice for small lawns or for people who do not need a heavy-duty tool. A straight-shaft trimmer has a shaft that is straight and typically longer than a curved-shaft trimmer. This can make the trimmer more stable and easier to reach under bushes and other hard-to-reach places. Straight-shaft trimmers are generally more powerful and durable than curved-shaft trimmers, making them a good choice for larger lawns or for people who need a more heavy-duty tool.
Why You Should Trust Us
There are a few key factors that were considered when evaluating the selected string trimmers. The power of a string trimmer was measured with higher cc or horsepower ratings meaning that the trimmer is more powerful and can handle tougher grass and weeds. The cutting path was also considered as a wider cutting path means that you’ll be able to cover more ground in a shorter amount of time. The weight of the trimmer was an important consideration as lighter trimmers will be easier to maneuver and less tiring to use. Trimmers with easy-to-use starting mechanisms that don’t require a lot of effort to start were also highly preferred.
How We Picked
Performance
Performance is an important consideration when getting a string trimmer because it can affect the effectiveness of the tool and your satisfaction with it. If the trimmer has poor performance, it may struggle to cut through thicker grass and weeds, or it may not run smoothly, which can be frustrating to use. On the other hand, a trimmer with good performance will be able to tackle a variety of grass and weed types with ease and run smoothly, making the job of trimming your lawn or garden more efficient and enjoyable. Performance is also relevant in terms of the overall durability and lifespan of the trimmer. A trimmer with good performance is likely to have a longer lifespan because it is not being strained to its limits and is running smoothly, whereas a trimmer with poor performance may break down more frequently or need more frequent repairs.
Easy to operate
When it comes to choosing a string trimmer, ease of operation is an important factor to consider. Some trimmers may be more user-friendly and easier to operate than others, depending on their design and features. Here are a few things to consider when looking for an easy-to-operate string trimmer:
- Weight: A lighter trimmer may be easier to handle and maneuver than a heavier one.
- Ergonomic design: Look for a trimmer with an ergonomic design that is comfortable to hold and use for an extended period.
- Adjustable handle: An adjustable handle can help you find the most comfortable and natural grip position, making the trimmer easier to operate.
- Easy starting: Some trimmers may have features such as a choke lever or a primer bulb that makes starting the engine easier.
- Easy line replacement: Some trimmers may have a bump head system that allows you to easily advance the line by tapping the cutting head on the ground, rather than manually replacing the line.
Size
Size is an important factor to consider when choosing a string trimmer, as it can affect the portability and maneuverability of the tool. Here are a few things to consider when it comes to size:
- Shaft length: A shorter shaft may be easier to maneuver in tight spaces, whereas a longer shaft may be more stable and easier to reach under bushes and other hard-to-reach places.
- Cutting width: A trimmer with a wider cutting width may be able to tackle larger areas of grass and weeds more quickly, but it may also be bulkier and harder to maneuver in tight spaces.
Weight
Weight is an important factor to consider when choosing a string trimmer, as it can affect the portability and maneuverability of the tool. A lighter trimmer may be easier to carry and handle, especially if you have to lift it over fences or into tight spaces. It may also be less tiring to use for extended periods of time. On the other hand, a heavier trimmer may be more stable and have more power, which can help tackle thicker grass and weeds. It may also be more durable and have a longer lifespan. Overall, the weight of a string trimmer is a matter of personal preference and the specific needs of your lawn or garden.
Overall build and design
The overall build and design of a string trimmer can affect its durability, performance, and ease of use. Here are a few things to consider when looking at the build and design of a trimmer:
- Material: Look for a trimmer that is made with high-quality materials such as aluminum or stainless steel, as these materials are more durable and resistant to corrosion.
- Engine: A trimmer with a reliable and well-made engine is more likely to perform well and have a longer lifespan.
- Cutting head: The cutting head should be sturdy and able to handle the wear and tear of regular use. Some cutting heads allow you to easily change the line size, which can help tackle different types of grass and weeds.
- Ergonomic design: Look for a trimmer with an ergonomic design that is comfortable to hold and use for an extended period of time.
- Adjustable handle: An adjustable handle can help you find the most comfortable and natural grip position, making the trimmer easier to operate.
Type of shaft
There are two main types of shafts used in string trimmers: curved and straight. The type of shaft can affect the maneuverability, reach, and stability of the trimmer. A curved-shaft trimmer has a shaft that is bent in an arc shape. This makes the trimmer shorter and more compact, which can make it easier to handle and maneuver. Curved-shaft trimmers are generally lighter in weight and less expensive than straight-shaft trimmers. A straight-shaft trimmer has a shaft that is straight and typically longer than a curved-shaft trimmer. This can make the trimmer more stable and easier to reach under bushes and other hard-to-reach places.
Price
It is generally a good idea to set a budget before shopping for a trimmer and to look for a tool that offers the features and performance you need at a price that is within your budget. Keep in mind that the cheapest option may not always be the best value, as cheaper trimmers may not be as durable or reliable as more expensive ones. On the other hand, a more expensive trimmer may not necessarily be the best choice if it has features or capabilities that you do not need.
Engine size
The size of the engine in a string trimmer can affect its performance and power. A larger engine typically produces more power and can handle thicker grass and weeds more easily than a smaller engine. However, a larger engine may also be heavier and less portable than a smaller one. In general, the size of the engine you need will depend on the size of your lawn and the types of grass and weeds you need to trim. If you have a large lawn with thick grass and weeds, a larger engine may be necessary to effectively trim the area. On the other hand, if you have a small lawn with mostly thin grass and weeds, a smaller engine may be sufficient. Keep in mind that a larger engine may also use more fuel and require more maintenance than a smaller one. Consider the trade-offs between power and fuel efficiency when deciding on the size of the engine you need.
Other features
There are many additional features that you may want to consider when choosing a string trimmer:
- Adjustable handle: An adjustable handle can help you find the most comfortable and natural grip position, making the trimmer easier to operate.
- Easy line replacement: Some trimmers may have a bump head system that allows you to easily advance the line by tapping the cutting head on the ground, rather than manually replacing the line.
- Line size: The size of the line used in the trimmer can affect its performance. Thicker lines can handle tougher weeds and grass, but they may also require more power from the engine.
- Anti-vibration technology: Some trimmers may have features that reduce vibration, which can make them more comfortable to use for extended periods of time.
- Noise level: Trimmers can be loud, so you may want to look for a model with a lower noise level if you are concerned about disturbing your neighbors or if you will be using the trimmer in a residential area.
How We Picked
-
Performance
Performance is relevant when getting a string trimmer because it determines how well the trimmer will be able to cut grass and weeds. If the trimmer has poor performance, it may struggle to cut through thicker grass and may require more passes to get the job done. This can be frustrating and can extend the amount of time it takes to complete the task. On the other hand, if the trimmer has good performance, it will be able to efficiently cut through grass and weeds, making the job quicker and easier.
-
Ease of Operation
Ease of operation is relevant when getting a string trimmer because it determines how easy it is to use the trimmer. Ease of operation can be affected by several factors, such as the weight of the trimmer, the position of the controls, and the power of the engine. A lighter trimmer will be easier to handle and maneuver, while a trimmer with well-placed controls will be more comfortable to use. An engine with sufficient power will be able to cut through grass and weeds more easily, making the job quicker and easier.
-
Overall Design and Build
A trimmer with a well-designed and sturdy build is likely to be more reliable and last longer than one that is poorly designed and poorly built. Additionally, a trimmer with a good design will be more comfortable and easier to use, which can make the task of cutting grass and weeds more enjoyable. The type of shaft is also relevant when getting a string trimmer because it can affect the performance and ease of use of the trimmer. There are two main types of shafts: straight and curved. A straight shaft is generally longer and more flexible, which can make it easier to reach and maneuver around obstacles. A curved shaft is generally shorter and less flexible, but it may be more comfortable to use for some people.
-
Cost-Effectiveness
A cost-effective trimmer provides a good balance between price and performance, offering good value for the price. On the other hand, a trimmer that is not cost-effective may be overpriced for the performance that it offers, or it may be prone to problems and repairs, which can add to the overall cost of ownership. When considering cost-effectiveness, it is important to consider the upfront price of the trimmer, as well as any ongoing costs, such as fuel and maintenance. Comparing the prices and features of different trimmers can help you find one that offers the best value for your money.
Care and Maintenance
Safety instructions for use
Here are some safety instructions to follow when using a string trimmer:
- Wear protective gear: Always wear eye protection and sturdy shoes when using a string trimmer.
- Follow the manufacturer’s instructions: Read the owner’s manual carefully and follow all instructions for proper use and maintenance of the trimmer.
- Check for damage: Before using the trimmer, inspect it for any damage or wear and tear, and repair or replace any damaged parts.
- Use the correct fuel mixture: Use the correct fuel mixture as recommended by the manufacturer to ensure optimal performance and reduce the risk of engine damage.
- Start the engine carefully: Follow the manufacturer’s instructions for starting the engine, and be sure to keep your face and hands away from the muffler and other hot parts of the engine.
- Hold the trimmer securely: Always keep a firm grip on the trimmer with both hands and maintain control of the tool at all times.
- Be aware of your surroundings: Keep a lookout for obstacles and be aware of your surroundings while using the trimmer. Avoid overhanging branches, power lines, and other hazards.
How to clean and how often
It is a good idea to clean your string trimmer regularly to keep it in good working order and extend its lifespan. Here are some steps to follow for cleaning your trimmer:
- Allow the trimmer to cool: If the trimmer has been in use, allow it to cool down before attempting to clean it.
- Remove any debris: Remove any grass clippings, dirt, or other debris that has accumulated on the trimmer.
- Clean the air filter: Remove the air filter and gently tap it to remove any dirt or debris. If the filter is very dirty, you may need to wash it in soapy water and allow it to dry completely before replacing it.
- Clean the spark plug: Use a spark plug wrench to remove the spark plug, and clean it with a wire brush or sandpaper.
- Clean the cutting head: Use a small brush or toothbrush to remove any grass clippings or debris from the cutting head.
- Wipe down the exterior: Use a clean cloth to wipe down the exterior of the trimmer, removing any dirt or grime.
It is a good idea to clean your string trimmer after each use, or at least once a week if you use it frequently. This will help to keep it in good working order and extend its lifespan.
Where and how to store when not in use
When storing your string trimmer, it is important to choose a dry, well-ventilated area that is out of reach of children and pets. Here are some additional tips for storing your trimmer:
- Clean the trimmer: Be sure to clean the trimmer before storing it to remove any dirt, grass clippings, or other debris.
- Protect the trimmer from the elements: If you will be storing the trimmer outdoors, consider covering it with a tarp or storing it in a shed or garage to protect it from the elements.
- Store the trimmer upright: Store the trimmer upright to prevent the fuel from leaking out of the carburetor.
- Disconnect the spark plug: To prevent the trimmer from accidentally starting, disconnect the spark plug and store it separately from the trimmer.
By following these storage tips, you can help to ensure that your string trimmer stays in good working order and is ready for use when you need it.
