1. Husqvarna 128LD – Best overall

Since 1689, consumers have enjoyed Husqvarna’s quality and innovation. So it’s no surprise that the Husqvarna 128LD is our favorite gas string trimmer.

Buyer’s guide to string trimmers

Wise shoppers know what to look for in a string trimmer, so we explain everything you need to know about the following factors and features.

Gas string trimmers

Gas-powered string trimmers give you the most bang for your buck, and the best gas string trimmers outperform the best electric models. However, gas trimmers are high-maintenance, and they release toxic emissions. They are also louder and heavier than most electric trimmers. 

2-stroke vs. 4-stroke Engine 

Most gas string trimmers have 2-stroke engines, but some have a 4-stroke engine. 2-stroke engines run on a mixture of gas and oil, but (like a car) 4-stroke engines run on straight gas and have a separate lubrication system. 4-stroke engines have more torque and less harmful emissions, but 2-stroke engines are more reliable and easier to maintain.

Engine displacement (cc)

The power of a gas engine is measured by engine displacement (cc).  Engines with higher cc produce more energy at lower engine speeds.

Typical gas-powered string trimmer specs

Engine displacement21 – 42 cc.Cutting width10 – 20 in.Weight10 – 18 lb.Line width.08 – .095Price$125 – $630

Cordless electric string trimmers

Cordless electric string trimmers typically run on lithium-ion batteries. Although they’re lower maintenance than gas engines, lithium-ion batteries need replacing every few years. High-end battery trimmers get pricey, but the best battery trimmers for light-duty tasks are very affordable. Battery models don’t emit harmful fumes, but they have limited runtime.

Power and runtime

Batteries with more amp hours (Ah) run longer on a single charge. The power of a battery is measured by voltage (V). Higher voltage batteries typically require more Ah for the same battery life.

Typical battery-powered string trimmer specs

Voltage12 – 80 voltAmp hours2 – 8 Ah Cutting width10 – 17 in.Weight4.5 – 18 lb.Line width.065 – .095Price$75 – $600

Corded electric string trimmers

Corded electric string trimmers are quiet, lightweight, and don’t emit toxic fumes. Unlike cordless string trimmers, corded models have unlimited runtime. However, they put you on a leash; you must stay close to an outlet. Corded trimmers aren’t great for large yards but are a low-maintenance and cost-effective option for homeowners with small yards. 

Amperage

Corded power tools with more amperage (amp) current electricity faster, thus generating more power. 

Typical corded electric string trimmer specs

Amperage4 – 10 ampCutting width12 – 18 in.Weight4.5 – 11 lb.Line width.065 – .08Price$50 – $130

Cutting swath

The wider the cutting swath, aka the cutting width, the more ground is covered with each pass. Thus, string trimmers with a wide cutting swath quickly finish the job. Gas trimmers tend to have a wider swath than electric trimmers.

Type of trimmer:Gas trimmersElectric trimmersAverage cutting width:17 inches14 inchesTypical range of cutting widths:10 – 20 inches10 – 17 inches

Cutting line

When string trimmer shopping, consider a trimmer’s line diameter and line feed.

Line diameter: Trimmers with a thicker string work best on lawns with dense growth. Homeowners who keep up with lawn care typically need a .065 to .08-inch line diameter, but large or overgrown yards fare better with a line diameter of .08 to .095 inches. 

Line feed: When a trimmer’s string wears out, the system feeds in the new string through a spool. Types of line feed systems include:

  • Bump feed systems are slow but cost-effective because they conserve string.
  • Fixed feed systems are faster than bump feeds but still preserve string. 
  • Automatic feed systems are the quickest but use more line than a bump or fixed feed trimmer. 

Shaft

A string trimmer’s shaft connects its engine/motor to the top of the trimmer and houses the trimmer’s drive system:

  • Straight-shaft trimmers are the most common. They have a longer lifespan, more torque, and better reach. 
  • Curved-shaft trimmers are more affordable, and they give the operator more control. They are better at maneuvering in tight spaces and around obstacles. 

Weight 

Lightweight trimmers are more ergonomic. Gas trimmers are typically the heaviest, while corded electric trimmers are the lightest. 

FAQ about string trimmers

1. Is a string trimmer the same as a weed eater? 

Weed Wacker, Weed Eater, and Whipper Snipper are all string trimmer brand names. The terms are often used interchangeably. Sometimes they are also called weed trimmers or grass trimmers. 

2. What’s better than a string trimmer?

A brush cutter is more potent than a string trimmer and is best for heavy-duty jobs.

3. What are the risks of string trimmers?

Follow proper safety precautions to avoid injuries from a string trimmer’s thrown debris, loud noise, and sharp edges. 

4. What’s the best lawn mower?

String trimmers are good for cutting down grass and weeds in tight spaces where a mower can’t reach, but you can trim your whole lawn a lot faster and with more precision with a lawn mower. Ideally, you’ll have one of each. 

The best lawn mowers include:

● Toro TimeMaster 21199 (Best self-propelled gas lawn mower)
● Ego Power+ LM2114 (Best battery push mower)
● John Deere S140 (Best lawn tractor)

5. What are the best leaf blowers?

Removing leaves and other debris is another important aspect of keeping a pristine lawn. You can clean up leaves much more efficiently with a leaf blower than with a rake. We recommend adding a high-quality leaf blower to your lawn care arsenal. 

The best gas-powered leaf blowers:

Handheld: Echo PB-2520
Backpack: Schröder SR-6400L
Walk-behind: Yardmax YF1565

The best battery-powered leaf blowers:

Handheld: Ego LB6504
Backpack: Worx Nitro WG572

When to call a lawn care pro

If you want a pristine lawn with dense green growth, consider hiring a lawn care pro. Routine mowing and edging is affordable, and many crews will also help with bushes, landscaping, and lawn treatments. You don’t even have to be home for most appointments, so you can enjoy your day without worrying about the lawn.

Automatic |12 lb 13 oz

The Ego Power+ Powerload with Line IQ ST1623T is the string trimmer that has and does it all. Best-in-class grass, heavy weed, and detail trimming? Check. Top-notch comfort, ergonomics, and battery performance? Check. Automatic line feed and no-fuss maintenance? Another check. This trimmer packs a punch with its 56V battery and 16-inch cutting path and is capable of handling the toughest and largest jobs in your yard while still being nimble enough to edge around a sidewalk or garden wall. Its two power speeds help control the amount of power that it can unleash, and the Powerload line feed and automatic line adjustment make for a hassle-free experience.

The downsides to the Ego Line IQ are minor when compared to its performance. It retails at a premium price point, as one would expect for such a high-performance machine. The Ego batteries, although leading the pack in runtime and compatibility across the Ego brand, are also quite heavy. The sling, purchased separately, can make a big difference in distributing the weight of this nearly 13-pound trimmer. If you're looking for a serious weed-eating machine capable of transforming and maintaining your yard, with the latest bells and whistles to make that job a breeze, the Ego Line IQ should be your go-to choice. If strong battery life is essential but you'd like to avoid the heavier weight associated with it, check out the Makita XRU15PT 36V. It's a couple of pounds lighter than the Ego, with a longer-lasting battery, although we should note it has a smaller cutting path.

If you're looking to stretch your dollar with a string trimmer purchase, check out the Black+Decker LST136. We were impressed with this small machine's abilities as its work stood up to considerably more expensive models that we tested. Despite its size, it performed remarkably well in all of our weed-eating tests — even thicker weeds. The LST136 is also one of the lightest trimmers we tested and collapses to half the size of other full-size models. The six different power settings help meet a variety of weed-trimming scenarios, and it boasts a healthy runtime. We loved the rotating head for edging along sidewalks.

Unfortunately, the design of the Black+Decker 136 also makes it tiring to use for extended periods. It extends larger than other collapsible models, but we still had to hold it closer to our body than we would have preferred, and the trigger grip grew tiring over time. It also has one of the larger guards, which can get in the way when making detailed cuts. However, the guard is quite effective at stopping plant and weed debris from getting thrown back at you. Ultimately, if you don't need a serious beast of a weed-eater, this is one of our favorite budget options for a cordless trimmer. If budget allows, we recommend looking at the Ryobi 40V HP Brushless Whisper RY402110VNM as a worthy alternative. Boasting the best battery life out of all the models tested to go along with an exceptionally quiet motor, the Ryobi Brushless Whisper is worth taking a look at for those prioritizing battery and noise.

Not powerful enough for thick weeds and shrubs

Large guard can get in the way

Shorter battery life

Button |7 lbs

The Craftsman V20 Weedwacker is an excellent, effective tool for keeping your small or medium-sized yard looking great, as well as light-duty brush clearing. It's lightweight and easy to break out for quick jobs or cleaning up what your mower missed, and replacing the spring when it runs out is a simple and easy process. The spool head will receive a lot of abuse as it's dragged and bumped against the ground, and Craftsman even offers a very affordable replacement.

For bigger jobs where thick grasses and brush have really taken over, the light and relatively quiet V20 does not have enough power. It does a better job of maintaining the yard rather than transforming it. During testing, the battery life averaged only 35 minutes. Although this isn't very long, it should suffice for edging along smaller lawns. While the guard effectively shielded us from debris, it is a little too large for detailed work. There are certainly more powerful models with even longer battery life, but we feel this string trimmer is the best choice for the average homeowner on a budget. If you're still trying to keep budget in mind but need something with a bit more power we suggest looking at the Ryobi 40V Expand-It. Thanks to a 40v battery the Ryobi boasts an impressive amount of power from an electric trimmer. While it does not offer the same level of comfort and ergonomics as pricer models, it can tackle larger jobs just as effectively.

For the versatile and highly capable string trimmer that does it all with ease, look no further than the Makita XRU15PT 36V. The ability to cut down both light tufts of grass and the most resistant weeds and plants is highly impressive. This machine handles detailed work with ease, helping to straighten lawn edges quickly and effectively. Cycling through the three different speed settings enables the user to operate the trimmer at its ideal speed for the job at hand. It's easy to use and comfortable to wield, thanks to its ergonomic grip. In addition, it has a long runtime and is exceptionally quiet compared to some other models.

Considering all the attributes, our complaints with this model are relatively minor. However, they are worth noting. For instance, we had to reference the instructions to figure out how to replace the line after it had run out. Once we did, the process was about as easy as it could be. Although there is more weight to handle on this trimmer, the weight is so well-balanced with the ergonomic grip that we didn't find it to be an issue. Lastly, we felt like the cutting path isn't as large as other models, despite boasting a potential 15-inch path. Overall, the Makita 36V balances all-around performance with ease-of-use and ergonomics that make it a model we'd keep reaching back for in our own yards, and we can easily recommend the Makita for a versatile pick. For those who find themselves cutting large areas and dense vegetation a powerful trimmer such as the Ego Power+ 15-Inch w/ Rapid Reload ST1502SA may be suited best. While it does not boast the versatility of the Makita, it excels in high weeds. At a much friendlier price point, this is a great option if you know the majority of your trimming is focused around denser areas and less so in finer grass.

Why You Should Trust Us


To say we put each string trimmer through its paces would be an understatement. We implemented over 120 individual tests between the 10 trimmers in the review, running each through the same 11 tests to comparatively assess aspects ranging from weed-eating power to noise levels. This allows us to rank each in accordance with its performance in each metric and make specific recommendations for the unique needs of homeowners or anyone looking to improve their yard. We paid retail price for each model to ensure an unbiased assessment of these string trimmers.

Our string trimmer testing is divided across four different metrics:
  • Performance (35% of overall score weighting)
  • Ease of Use (35% weighting)
  • Battery (20% weighting)
  • Noise (10% weighting)

Our string trimmer testing is divided across

Our expert string trimmer testing and review team is comprised of a powerhouse trio of yard-tool testers, Hale Milano, Michelle Powell, and David Wise. Hale is a veteran tester on everything from cordless leaf blowers to stud finders and no stranger to battery-powered yard tools. Living in the woods, Hale has plenty of experience working to maintain a — somewhat — pristine yard and lawn. Michelle has made a career of evaluating products side-by-side, comprehensively testing and scoring the smallest details, and differentiating factors on everything from coffee grinders to cordless power tools. David has formal training as a mechanical engineer with extensive experience in lithium batteries and electrical power systems, which he gained from working on electric vehicles and underwater robots.

In total, we conducted eleven tests for each string trimmer that were divided among four weighted rating metrics. Each of these metrics — Performance, Ease of Use, Battery, and Noise — are weighted proportional to their importance to overall string trimmer performance. The score for each metric is determined by the performance of each trimmer in the tests composing each metric.


Value


If you're shopping for a bargain weed eater, then two models stand out: the Black+Decker LST136 and the Craftsman V20 Weedwacker. These typically cost about half as much — or even a little less — than our top-scoring models, the Ego Line IQ and the Makita 36V, and both are solid string trimmers, costing about the same.

The Black+Decker LST136 is perfect for clearing small areas of your yard.The Craftsman V20 is perfect for light-duty work around the yard.

Both the Black+Decker and Craftsman are collapsible models that are great for your average suburban yard.


The Black+Decker 136 model is a bit more powerful than the Craftsman V20, and it also has a longer battery life. Deciding between the two will likely come down to whether or not you already have tools with compatible batteries. Both are lightweight and great for quick clean-up tasks. While neither is up to snuff for professional operations, both are worthy of consideration for the average homeowner.

Performance


Weed-eating performance composes the greatest share of a product's overall score. To rank and compare the weed-eating skills of each string trimmer, we looked at the effectiveness of each model when it came to trimming plain grass and sections of a yard, how each handled dense and hard-to-cut vegetation, as well as how much precision you have for trimming edges and cleaning up around delicate obstacles.


The Ego Line IQ is the best of the best when it comes to eating weeds. It is exceptionally effective at eliminating weeds, cutting through pretty much any grasses, weeds, shrubs, and bushes we pitted them against smoothly and effectively. Its variable squeeze trigger and two selectable speeds tackle tall grass and dense weeds with ease, even cutting through burly stalks and stems without showing any sign of a struggle.

Dense, thick, and high weeds are no problem for this Ego, and the automatic line feed keeps the string length topped off perfectly.

The Black+Decker 136, snagged second place thanks to its outstanding performance as a precision edging machine. The pivoting head and wire guard enabled hassle-free crisp lines along our driveways and sidewalks, while still holding the trimmer normally.

Also scoring well across all of our performance tests was the Makita 36V. Although it did not stand out in any one particular test, we had no qualms with its performance in any of them, and it earned its place among the leaders with ease. We did find the Makita quite enjoyable to use in close quarters. Its slow speed settings enabled nimble and controlled cuts around sprinklers, lawn ornaments, and flower beds without damaging them.

We liked that this tool has plenty of power to cut lots of plants at once, as well as a slow speed for more precise use.

Ease of Use


Like the performance metric, ease of use also constitutes 35% of the total score for each string trimmer. Here we compared the weight and guard design of each trimmer, as well as how comfortable and balanced they are to hold. We also compared the ease of replacing and feeding the line and noted if there was a shoulder strap attachment.


The Ego Line IQ, again, earned the top score in this metric. It is exceptionally well balanced, even with the large four amp-hour battery installed, making it easy to carry one-handed and to wield through fields of grass. If you have a sling, attaching it to the included sling attachment point relieves the arms of all the weight and holds the trimmer head at a consistent height. We found this very useful when trimming sections of the lawn to keep the cutting height even. The guard is also significantly better than most. It kept debris from flying back, although we still wore safety glasses, and it also did not block our view when making detailed cuts.

The Ego Line IQ's guard is the perfect blend between blocking debris and a clear field of view.

By far, the nicest feature we tested during our ease of use metric was the Powerload and Line IQ technology found in the Ego Line IQ trimmer. As with other models, simply feed the new line through both eyelets to replace the trimming line. Then, with the Powerload, simply press the wind button, and it will automatically spool the line until about eight inches are left on each end. The automatic line feed then keeps the trimming line set at about seven and a half inches, dispensing more as needed.

The runner-up was the Makita 36V. We loved the included shoulder strap, something other models require you to purchase separately. The balance on the Makita, even without the sling, is exceptional, and the molded rubber grips provide a secure way to control the trimmer. The guard is too small to effectively block much debris from spraying backward, although it did enable us to trim in tight corners with precision.

We found the Makita XRU15PT string trimmer to be exceptionally well-balanced and easy to use.

This trimmer employs a bump feed to dispense more string, but it's a little more difficult to replace the string than some of the other models. There aren't alignment indicators on the spool, which forced us to consult a manual, but it was straightforward once we became familiar with the process. This minor drawback should only be an issue once or twice, after which you'll get the hang of it.

It took us a little bit of effort to figure out how to swap the string on the Makita model the first time.

The Craftsman V20 and the Black+Decker 136 both scored well regarding convenience and ease of use. Line replacement on these models is straightforward - we didn't even need the manual for the Black+Decker, although you do need to remove the head of the trimmer to do so.

Replacing the spool and line on the LST136 is straightforward, though keeping the line wound tightly is a little tricky.

The Black+Decker 136 and Craftsman V20 are both very simple to pick up and use right away. Both are very lightweight, making them easiest to handle and finesse in tight areas around obstacles. They're fairly comfortable to use, even without a shoulder strap. We did not find them as well balanced as full-size models, though, and wouldn't recommend them for larger jobs.

The Craftsman V20 is a compact trimmer that is perfect for basic yard trimming tasks.

Both of these models collapse down to roughly half the size of other models; it is helpful for storage, but they're not as comfortable to use for long periods.


An honorable mention in our ease of use metric is the Ryobi 40V HP Brushless Whisper RY402110VNM. This is a well-balanced, although heavy, full-size trimmer. We wish that it had a sling to balance the heavy weight but found that its design kept it at the perfect height for trimming grass. It also has a larger-than-average guard that stopped quite a bit of debris from flying backward at us.

The Ryobi is a heavier but well-balanced trimmer and very pleasant to use.

Battery


Our next metric focused on the battery system of each string trimmer, and this accounts for 20% of each product's final score. We based the bulk of this score on the maximum runtime for each product and the time it took to recharge the battery from empty. We measured the runtime for these weed eaters when they were not actually eating weeds, so you will probably get lower numbers if you're chewing through dense vegetation or particularly stubborn weeds.


The Ryobi 40V Whisper cut down the competition in our run time test, with its massive six amp-hour battery powering the trimmer on high for over two hours.

The Greenworks 14-inch 40V and the Makita 36V lasted for around 90 minutes before the batteries gave out, and they both have a series of different speed settings. Determining which battery system is best for you depends on whether or not you have any other devices that run on compatible batteries that you can use to prolong the run time.

You have three different speeds to choose from with the Makita XRU15PT, which allows you to save battery power for the thick brush jobs that need it.

Noise


Our final metric focused on the amount of noise that each string trimmer generated while in use. This metric accounted for 10% of the overall score. To determine scores, we used a sound level meter to measure the noise from each string trimmer at ear level. Since the sound can vary depending on the weeds you are trimming, our sound test was not during actual cutting. We also rated the pitch of each trimmer. Most trimmers have a louder start-up sequence as the line begins to spin; we took our decibel readings once each unit steadied out.


The Makita 36V took home the top spot in this metric. Our meter recorded 83.6 decibels when this model was in use. After its initial start-up, the Makita is incredibly pleasant and quiet to use.

In addition to being very powerful, the Makita is also one of the quieter models out there.

The Craftsman V20 registered slightly quieter than the Makita 36V at only 81.5 decibels and was one of the quietest of the trimmers we tested. However, it suffered from an annoying, high-pitched whine that cost it the top spot. The Black+Decker LST300 had opposite characteristics that landed it close to the Craftsman overall in noise. It tested at 83.1 decibels but had a very pleasant and low pitch.
