All 18 String Trimmers We Recommend
Best Cordless String Trimmers
Cordless weed wackers give you the most flexibility since you’re not tethered by a cord. Although they are heavier than corded string trimmers since they have a battery pack, they do give decent power and run-time.
Best string trimmer for: Large gardens
Best Electric Weed Eaters
If you don’t want to worry about charging batteries between use, a corded (or electric) weed eater is a better option. They are also lighter than cordless weed eaters since they don’t have the bulky battery pack attached.
Best string trimmer for: Small to medium-sized gardens
Black + Decker BESTA510
Best Gas Powered String Trimmers
Gas-powered string trimmers are a much more heavy-duty option for professionals or homeowners with long, thick weeds to clear. These are a popular option for their impressive power, making quick work of overgrowth.
Best string trimmer for: Thick weeds and tall growth
Best Walk-Behind Weed Eaters
Walk-behind weed eaters look like a push lawn mower but cut like a weed trimmer. They are designed for the thickest overgrowth that would be difficult to maneuver through with a handheld string trimmer.
Best string trimmer for: Thick weeds, tough terrain
Best 3-in-1 Weed Wackers
If you’re looking for a much more lightweight tool for keeping your small lawn manicured, a 3-in-1 weed wacker gives better functionality. You can mow, trim, and edge your lawn using one tool.
Best string trimmer for: Trimming weeds, mowing & edging
Black + Decker MTC220
Black + Decker MTE912
Black + Decker MTD100
Best Brush Cutters
Unlike other string trimmers, a brush cutter has steel blades like a hedge trimmer. This is the tool for you if you’re a professional landscaper or have a lot of overgrowth or shrubs to clear.
Best for: Thick weeds, small trees, and shrubs
Best Battery Powered Weed Eater
Battery weed eaters are best for anyone who wants a portable, easy to handle trimmer for their garden. Here are some things to keep in mind:
- Lithium-ion battery: The best cordless string trimmers have lithium-ion batteries for extended life.
- Straight shaft: These are most common, allowing you to get under fences or in hard to reach corners. However, curved shafts are available for large, open spaces.
- 2-in-1 capability: Some battery powered weed wackers have 2-in-1 capability, meaning it can also be used as a lawn edger.
- Trimmer line: Look for trimmer line between 0.060” and 0.095” thick for the best performance.
Best Battery Powered Weed Eater Reviews of 2021
Greenworks 21302 13-Inch 40V Cordless String Trimmer/Edger
Best cordless string trimmer
The impressive 40V battery and decent cutting path size make this a good weed eater for most moderate weed trimming.
1 Greenworks 21302 Review
Are you looking for a powerful weed wacker with the flexibility to move around unobstructed by a cord? The Greenworks 21302 is our best in class pick. This lightweight electric weed eater has a decent 40V battery giving about 30 minutes of run time. And the 13-inch cut path makes this a good size for medium-sized gardens.
The best feature of the Greenworks 21302 battery powered string trimmer is the 90-degree pivoting head with an edging wheel. This 2-in-1 string trimmer allows you to get two jobs done at once. The downside is the trim feed can be a little difficult to thread.
Overall, if you want a powerful, cordless weed eater for standard lawns, the Greenworks 21302 is your best option.
Worx WG163.8 GT 3.0 20V PowerShare 12″ Cordless String Trimmer & Edger
Less powerful, more functional
The telescopic shaft and pivoting head make this a multi-functional weed trimmer & edger.
2 Worx WG163.8 Review
The Worx WG163.8 is by far the most popular cordless weed trimmers on the market. Slightly smaller than our best pick with a trim width of 12 inches, this weed eater also has a pivoting head that converts it into a lawn edger. However, it only has a 20V battery, so it is best suited to light weed maintenance.
The Worx WG163.8 battery string trimmer has some additional features though which make it good value for money. The front handle is adjustable to give the most comfortable grip. Plus, the shaft telescopes out to reach high hedges or tough spots behind trees and shrubs.
Although it is a less powerful option, the Worx WG163.8 is still sufficient for light to medium trimming and a good option for anyone looking for a multi-functional string trimmer for garden projects.
Greenworks 21342 12-Inch 24V Cordless String Trimmer/Edger
Budget-friendly cordless weed eater
Lightweight and a fairly small battery, this string trimmer is best for small trimming and edging jobs.
3 Greenworks 21342 Review
If you need a weed trimmer but your budget is tight, the Greenworks 21342 is a decent yet affordable option. It has a 24V motor and a 12-inch cutting path, making it optimal for light trimming and small spaces. However, this cordless weed eater won’t live up to thick thatch or shrubs.
If you struggle to carry larger models, the Greenworks 21342 is also very lightweight so won’t cause fatigue. This one also has a telescopic handle and because it is lighter, it’s suited to hedge trimming too. But with the 25-minute runtime, it is suited to small projects.
Though this is a budget option, it’s a decent weed trimmer and sufficient for most light trimming and edging work.
Best Corded Weed Trimmer
Electric string trimmers are environmentally friendly with enough power for regular weeding. Although they give unlimited run time, they are best suited to small to mid-sized gardens due to the cord restrictions.
- Motor: The larger the motor, the more powerful the string trimmer. The most powerful are around 10 amps.
- Lightweight: Without a battery attached, electric weed eaters are the most lightweight.
- Cutting swath: Sizes range from 10” up to 18” depending on the size of your lawn.
- Unlimited run time: With no battery to charge or fuel to top up, you have unlimited use.
- Extension cord needed: For larger areas, you will need a reliable extension cord.
Best Corded Weed Trimmer Reviews of 2021
Greenworks 21142 18-Inch 10-Amp Corded String Trimmer
Powerful, unlimited run time
The impressive 10-amp motor makes this corded string trimmer as powerful as some gas-powered options.
1 Greenworks 21142 Review
Do you want a powerful string trimmer with unlimited run time? The Greenworks 21142 has an impressive 10-amp motor and substantial 18-inch cutting path. This is sufficient for large lawns and will quite easily cut through most thick weeds.
Weighing 13lbs, this is a lightweight electric grass trimmer. However, if you have large areas to cover, a harness may be necessary to prevent fatigue. You can also convert the Greenworks 21142 string trimmer into a saw, cultivator, or leaf blower by purchasing the additional accessories which is a bonus.
With a powerful motor and quality construction, the Greenworks 21142 is the best corded weed eater for most gardeners.
BLACK+DECKER BESTA510 Electric String Trimmer with Auto Feed
Lightweight, less powerful
This medium-sized weed eater has a less powerful motor suited for regular, light trimming and edging.
2 Black + Decker BESTA510 Review
If you don’t need a grass trimmer as powerful as our best in class option, the Black + Decker BESTA510 is a good option. The 6.5-amp motor is still sufficient for everyday weed trimming and grass edging, and the 14-inch cutting path is suited to medium-sized projects.
Because this is a smaller weed eater, it’s also less than half the weight of our best pick. This makes it a good option for anyone who would struggle to carry the larger option.
Overall, this is a great value string trimmer. The lightweight design and smaller motor make it suited to infrequent trimming and grass edging.
Greenworks 21212 13-Inch Electric Corded String Trimmer
Best for small yards
With the smallest motor and cutting path, this weed eater is best for small lawns.
3 Greenworks 21212 Review
With a 4-amp motor and 13-inch cutting path, the Greenworks 21212 is the smallest corded string trimmer. However, it comes with a telescopic pole which makes it a useful tool for large hedges that need trimming.
Although this one is heavier than our best value pick, it’s still light enough for most light weed trimming and edging work. And can be lifted easily enough for high trimming.
If you have a small yard to maintain and want an affordable weed eater for odd jobs, the Greenworks 21212 is a great choice.
Best Gas String Trimmer
Although gas weed trimmers are the most powerful, they are also the loudest and heaviest to handle. Here are some things to keep in mind when choosing the right one:
- Price: Since gas weed trimmers have gas-powered engines, they are the most expensive category.
- Motor size: The larger the motor, the more powerful. 28cc is a good size for most heavy-duty jobs.
- Body harness: Since gas string trimmers are heavy, you should consider one with a body hardness to take some of the weight and make large jobs easier.
- Translucent fuel tank: The best gas weed eaters have a see-through tank so you can easily see when it needs topping up with gas.
Best Gas String Trimmer Reviews of 2021
Husqvarna 324L 4-Cycle 18″ Cutting Path Gas String Trimmer
Cuts through thick thatch
The heavy-duty motor and large cutting width make this weed eater powerful enough for the toughest jobs.
1 Husqvarna 324L Review
The 25cc 4-cycle motor and wide 18-inch cutting path mean this gas string trimmer will cut through the thickest thatch and overgrowth with ease. You will burn through string quickly, but the tap-and-go feature allows you to release new string mid-project without stopping. This is great if you have a large area to cover.
It is extremely loud, but that is expected for a heavy-duty gas weed eater. And although it does have a mudguard, it can fling debris quite far with the power it puts out, so safety goggles are recommended.
Even so, the Husqvarna 324L is easily one of the best gas weed trimmers on the market and will make quick work of thick weeds.
Husqvarna 128LD 17″ Cutting Path Detachable Gas String Trimmer
Powerful, great value
The large motor and touch-and-go feature are impressive for the price of this gas weed trimmer.
2 Husqvarna 128LD Review
This gas-powered weed wacker is the smaller sibling of our best in class pick. The motor is slightly less powerful at 28cc 2-cycle, and the cutting width is a touch smaller at 17 inches. However, this is still powerful enough for tough weeds and brush.
Like our best in class pick, the Husqvarna 128LD has the touch-and-go feature which lets you renew the string without stopping. If you’re working on tough weeds, this is a great feature to save time.
If you want the power of gas string trimmer at a good price, the Husqvarna 128LD is a good option and will live up to most weed and brush jobs.
Remington RM25S 25cc 2-Cycle Straight Shaft Gas Powered Weed Wacker
Best for beginners
With a less powerful motor and low price point, this is a good starter weed eater.
3 Remington RM25 Review
If you’re new to gas weed trimmers and want something affordable to try out, the Remington RM25 is a great budget option. The 25cc 2-cycle engine won’t live up to professional landscaping, but it’s powerful enough for most homeowner weed issues.
The handle adjusts to give you the best grip and control for different types of projects. And the 16-inch cutting width still gets large areas trimmed quickly. However, this is the heaviest gas weed eater of all three picks, so you’ll probably need a harness for extended projects.
For the budget price point, the Remington RM25 is a decent weed wacker for beginners.
Best String Trimmer Mower
A walk behind string trimmer easily cuts through thick weeds, long grass, and most stubborn brush. And because you’re pushing, not carrying, it’s an easier tool to use.
- Self-propelling: If you find pushing a lawn mower difficult, a self-propelled string trimmer is a less strenuous solution.
- Gas-powered: This gives the most powerful output and there’s no need to worry about running over cables.
- Never kill engine: disengage the cutting head without killing the engine to easily remove branches or rocks in your way.
- Multi-terrain: Large wheels mean walk-behind weed wackers can easily traverse rocky terrain, unlike lawn mowers.
Best String Trimmer Mower Reviews of 2021
EARTHQUAKE 28463 M205 4-Cycle Viper Engine Walk Behind String Mower
Best for tough, uneven terrain
If you have a large plot with waist-high weeds and grass, this walk-behind weed eater will make short work of it.
1 EARTHQUAKE 28463 Review
Do you want a powerful yet quiet tool for trimming down tough weeds and brush? A walk-behind weed eater is a less strenuous alternative to a regular gas-powered string trimmer. And when it comes to the best string trimmer mower, the Earthquake 28463 is a popular choice.
The 150cc 4-cycle viper engine is powerful enough to cut through almost anything. And the 14-inch chunky wheels mean it can easily roll over long grass, thick thatch, or rough terrain without getting stuck.
Overall, if you have a large, overgrown garden with even the toughest weeds, the Earthquake 28463 commercial weed wacker is the tool for the job.
TAZZ 35258 One-Piece Steel Deck Walk-Behind String Mower/Trimmer
Equally powerful, great value
With many of the same impressive features as our top-rated walk-behind, this offers great value for money.
2 Tazz 35258 Review
The Tazz 35258 has many of the same features as our best in class. It features a heavy-duty 158cc 4-cycle engine as well as a 22-inch cutting path to make large lawns quick and easy. It also features the 14-inch wheels to help traverse uneven, rocky terrain without getting jammed.
Just like our best pick, the Tazz 35258 also has a never-kill engine, meaning you can keep the motor running when the string trimmer is disengaged. This saves a lot of effort starting the engine back up every time you have to move a branch or rock from your path.
For anyone looking for a great value push weed eater that’s powerful enough for thick, uneven brush, the Tazz 35258 is a great option.
Southland SWSTM4317 Outdoor Power Equipment Wheeled String Trimmer
Best for small areas
With a smaller engine and compact design, this walk-behind weed eater is designed for smaller gardens.
3 Southland SWSTM4317 Review
If you have a smaller yard or less invasive weeds, the Southland SWSTM4317 is a budget-friendly walk-behind weed trimmer. The smaller 43cc engine won’t cut through tall grass or thick thatch as easily, but it’s still powerful enough for unruly grass and overgrowth.
What makes this walk-behind stand out is the 30-degree swiveling trim head. This allows you to get tight alongside fences or under thick trees with much more ease. The Southland SWSTM4317 is also more compact than our best in class and value picks, so is easier to push and transport.
Although not as powerful as our other picks, this is the best walk-behind string trimmer for moderate overgrowth and smaller areas.
Best Weed Trimmer Mower Combo
If you don’t want multiple lawn care tools cluttering your shed, a string trimmer mower edger combo is a convenient option.
- 3-in-1 functions: As well as mowing and trimming, you can create clean, crisp lawn lines along flowerbeds, patios, and other areas (also known as edging).
- Corded vs cordless: 3-in-1 tools come with or without cords. Which you get will depend on whether you want unlimited run time or more power.
- Removable deck: If you already have a weed eater, you can purchase a removable deck that will convert it into a lawn mower.
- Adjustable height: The deck has an adjustable height to customize to long or short grass.
- Foot peddle release: An easy foot peddle releases the string trimmer to easily convert back to weed wacking after mowing.

Although the compact mower isn’t powerful enough for large, overgrown lawns, it does give an efficient option for tidying up or mowing small yards up to 1,200 square feet.
Though this isn’t a powerful enough option for extremely overgrown yards or professional landscapers, it’s a lightweight, compact option for infrequent gardeners.
BLACK+DECKER MTE912 3-in-1 String Trimmer/Edger & Lawn Mower
Best corded 3-in-1 weed eater
Offering unlimited run time and more powerful output, this string trimmer mower combo is good for small yards.
2 Black + Decker MTE912 Review
Made for smaller gardens, the Black + Decker MTE912 is recommended for lawns up to 750 square feet. Unlike our best in class pick, this 3-in-1 weed wacker is corded. Although this gives less flexibility, it offers unlimited run time and a more consistent performance.
The 6.5-amp motor is powerful enough for small lawns and moderate weed growth. However, even a corded 3-in-1 string trimmer isn’t powerful enough for thick brush.
If you prefer corded lawn tools for the best performance and unlimited run time, the Black + Decker MTE912 is our top choice.
BLACK+DECKER MTD100 Lawn Mower Removable Deck for String Trimmer
String trimmer deck piece
If you already have a weed eater, this deck will convert it into a lawnmower, saving you money.
3 Black + Decker MTD100 Review

It’s compatible with most 12-inch trimmer/edgers by Black + Decker, but make sure to check your model before purchasing.

Best Brush Cutter Reviews of 2021
Husqvarna 336FR 966604702 Bike Handle Pro Brushcutter
Best for professionals
The powerful engine and adjustable handlebar make this a heavy-duty tool for cutting through most overgrowth.
1 Husqvarna 336FR Review
Do you need a weed eater that can handle the thickest weeds, shrubs, and small trees? The Husqvarna 336FR brush cutter is a heavy-duty tool for the job. Unlike a string trimmer, a brush cutter is fitted with steel blades that easily cut through branches, shrubs and most overgrowth with ease.
The Husqvarna 336FR has a powerful 34.6cc engine and is fitted with a handlebar for added control. It comes with both a brush and saw blade for use on lawns and tree branches or thick thatch. It is a heavy tool, but comes with a harness which shifts most of the weight to your back for better comfort.
Though the Husqvarna 336FR is overkill for most gardens, this brush cutter is an effective tool for professional landscapers.
Craftsman WS235 2-Cycle Straight Shaft Gas Powered Brush Cutter & String Trimmer
Best for homeowners
With a smaller engine and no additional handlebar, this is a less powerful brush cutter for non-professionals.
2 Craftsman WS235 Review
The Craftsman WS235 is less powerful than our best in class option, and more suited to homeowners who have dense overgrowth. The 27cc engine is powerful enough for most thick brush, however, the Craftsman brush cutter doesn’t have a second handlebar. This can make it slightly harder to control when working with thick weeds.
Whereas our best in class pick comes with a harness, the Craftsman WS235 comes with a shoulder strap. But because this is a lighter tool, this is sufficient for longer projects.
Overall, if you’re a homeowner looking for a powerful enough tool for thick weeds and brush, this Craftsman brush cutter is a good option.
TrimmerPlus BC720 Brushcutter with J-Handle for Attachment Capable String Trimmers
Brush cutter add-on
Easily convert your attachment-capable string trimmer into a brush cutter for tougher jobs.

If you already own an attachment-capable weed wacker, the TrimmerPlus BC720 is an add-on that converts it into a brush cutter. This add-on comes with a steel blade head, J-bar and shoulder strap to fully convert your attachment-capable weed eater into an impressive brush cutter.
Although this isn’t as powerful as our other options, it’s a budget-friendly way of getting the power of a brush cutter for larger jobs such as cutting through dense overgrowth or taking down small, young trees. As with any add-on feature, check the model of your string trimmer to ensure they are compatible.
String Trimmer Buying Guide
What is a string trimmer?
A string trimmer is a gardening tool used to get rid of weeds, long grass, and unwanted overgrowth. You might have heard the terms weed wacker, weed trimmer, grass trimmer or weed eater, these are all the same thing so the terms are used interchangeably.
How do weed eaters work?
The head of the tool has a nylon cord that spins at high speeds to cut through grass and weeds. These cords vary in thickness depending on the toughness of the weeds.
The nylon does wear down over time and needs to be replaced. This needs to be done manually (known as a manual feed) in some weed wackers, whereas others have automatic feeds which push out new cord when needed (known as a bump feed).

- Greenworks weed wackers: these are some of the most popular weed eaters available. Greenworks offer both corded and cordless weed eaters at a range of price points. Most popular for their cordless grass trimmers, Greenworks feature long-life batteries and a good run time for most gardeners.

Weed wacker vs brush cutter: what’s the difference?
A string trimmer has a nylon cord that cuts weeds and grass. On the other hand, a brush cutter has a steel blade. This makes it much more powerful and better for tough jobs like cutting through dense brush or shrubbery.
You can buy multi-functional tools that can switch between a nylon string cutter and a steel blade. This allows you to use it for a range of jobs, regardless of the thickness of overgrowth.
