The 4 best string trimmers of 2026, reviewed by a pro landscaper

The best string trimmers are a total game-changer for yard work. I’m old enough to remember the extended long-handled swivel grass shears my dad and grandpa used to trim their lawns. I myself have owned multiple weed trimmers, from a screaming two-cycle gas-powered model when I started as a landscaper 30 years ago to a little corded option my wife nabbed for our short-term rental home. When we bought our 1.5-acre property, I upgraded to a battery-powered weed eater, but still keep a two-cycle weed whacker for work in the back acre.

The recommendations here come from my personal experience as a gardening pro. I’ve used these gadgets to trim weeds, of course, but also to keep wild plants contained, tidy up lawn edges around trees and shrubs and cut the grass in ditches. The best string trimmers truly serve multiple purposes; along with a lawn mower (and the occasional application of weed killer), they can make all the difference between a scraggly yard and a manicured one.

Stihl is renowned for producing top-of-the-line power equipment for landscaping, and while it has ventured into the battery-powered market, its true expertise lies in gas-powered models. I selected this string trimmer as best overall for its durability, reliability and ease of use. Plus, my landscape foreman swears by this model, which means a lot since his crews use them day in and day out throughout the season, logging multiple hours trimming and edging lawns and whacking weeds. If it’s the best for them, it’s best for anyone!

Stihl’s proprietary anti-vibration system helps reduce operator fatigue for pros, but it’s a boon for homeowners unaccustomed to extended periods of use. The TapAction line advance feature eliminates the need to stop and advance the string manually, so you can keep working and get the job done fast. Best of all, the relatively lightweight motor and shaft with an easy-to-grip loop handle, provides ample power to knock down established weeds while being nimble enough to trim the lawn near trees, shrubs and flowers.

Ryobi

A budget weed whacker like this Ryobi is the perfect choice for anyone wanting to keep their small yard neat and tidy. This super-light model is easy to wield, and I have found the Ryobi battery technology exceptional, with long run times and quick recharges. (See my electric lawnmower review, where the best overall mower was a Ryobi.) The fact that this string trimmer works with the same battery system as all their other tools makes it an excellent addition to any arsenal of Ryobi cordless drills, saws or sanders.

With ample power for basic weed-eating and lawn trimming, and an easy-to-use, low-noise design, the budget pricing makes it almost too good to be true. Owners of top-of-the-line gas-powered string trimmers might be tempted to buy this Ryobi just to have it handy for quick tasks, avoiding the hassle of firing up a two-cycle engine to whack just a few small weeds. The smaller line diameter does limit this machine to soft-stemmed weeds and grasses, but the pivoting head makes it perfect for cleaning up between the lawn and walkways or planting beds.

ProsGood for edgingA lot of power for the priceRechargeable battery can be used with all Ryobi One+ toolsLightweight and easy to maneuverConsUses a narrower trimmer line, so not suitable for tough weeds Image for the large product module

Milwaukee has been at the forefront of battery-powered tools for years, so it is no surprise that this string trimmer kit came out on top as the best battery-powered model. I highly recommend it because I’ve owned one for several years and have found it powerful, adaptable and easy to use, making it the perfect battery-powered weed whacker for any homeowner. Best of all, this tool is more than a weed eater. The base unit accommodates multiple attachments, including a string trimmer, a hedge trimmer, a pole saw, an edger and a brush cutter, all utilizing the Quik-Lok mechanism, which makes swapping them a snap.

The tool is powered by the long-established M18 Fuel battery system, a leader in the industry. The string trimmer attachment is relatively quiet and has good runtime. With a roughly 0.01-inch-diameter line, it cuts through tough weeds easily. The brush cutter attachment features a blade that rips through woody stems, enhancing this tool’s versatility. All told, this Milwaukee is an excellent choice for any yard, large or small.

Echo

Homeowners with large yards or open fields need a weed whacker designed to knock down wide swaths of tough weeds and tall grasses, and this Echo model is an excellent choice for several reasons. First, it has the largest cutting width of any string trimmer I could find, at a full 20 inches (most other models land between 13 and 16 inches). Second, the pro-grade U-handle with a shoulder strap lets you comfortably swing the trimming head to and fro like a scythe, literally mowing down whatever is in front of you. Finally, the 1.8-horsepower two-cycle gas engine powers a high-capacity speed feed head that keeps cutting until the gas tank runs dry.

Echo, like Stihl, is a brand trusted by professional landscapers. Known for durability and reliability, their machines stand up to daily use, making them the perfect choice for any property owner with multiple acres of land. I love this model especially for the U-handle, but also because I know I can rely on the engine platform to run all day if need be and, with proper maintenance, perform perfectly for years to come.

The first thing to think about is what type and how many weeds you need to whack on a regular basis. How — and how often — will the weed trimmer be used? For some, this may mean owning more than one, while for others it means finding the very best fit for their yard. Here are specifics to look for when shopping:

✓ Line diameter and cutting width: Line diameter refers to the thickness of the string being used in the trimmer. You’ll see 0.065-, 0.08- and 0.095-inch diameters most often; the thicker it is, the better the string line can tackle tough weeds and the longer it will last before more needs to be re-fed. As for cutting width, the wider it is, the faster the job gets done.

✓ Weight and horsepower/voltage: Power isn’t everything, and anyone who has wielded a weed whacker for more than 15 minutes knows that lightweight maneuverability is more important. That said, most homeowners can get away with electric string trimmers that operate on an 18-volt battery. If you’re buying a gas-powered model, you’ll need to balance horsepower with maneuverability.

✓ Engine type: Are you going gas or electric? Gas packs power, but usually these string trimmers are heavier and louder; you’ll also have to deal with gas fumes. Some areas are starting to phase out gas-powered lawn tools, so you should check local guidelines to make sure you can use one if that’s your preference. Electric string trimmers come in either corded or battery-powered versions. We prefer battery-powered options because you aren’t limited by cord length, and newer battery systems are pretty powerful. That said, batteries and chargers cost extra, and you’ll need to recharge them.

✓ Line advance: Another crucial consideration novices don’t consider is how difficult it is to install or feed the string line that does the cutting. This is especially important when tackling weeds with tough stems, which can quickly whittle away the string, so it needs to be replenished often. I look for auto- or bump-feed models that extend the line when you bump the weed trimmer’s head on the ground.

✓ Adaptability: Does the model have an interchangeable head? Some of the best weed whackers allow multiple tool heads to be installed on the main unit, such as a blade instead of a string, an edger, or even a hedge trimmer. This turns your weed whacker into an all-in-one landscaping tool platform, so if it’s important to you, make sure the machine you get has an interchangeable head.

✓ Longevity and maintenance: Gas-powered weed whackers require yearly or even monthly service, requiring a bit of know-how to clean the air filter, change the spark plug and engine oil (or, if it is a two-cycle engine, mix the gas with oil). Battery-powered whackers are simpler. I consider them plug-and-play with minimal maintenance, but unlike a gas trimmer, they require a lead time to charge and may not have sufficient runtime between charges to finish the job. In contrast, a gas trimmer can be immediately refueled.

How we chose these string trimmers

I’ve owned multiple weed whackers over the years, including commercial-grade gas-powered models, a corded electric type and a battery-powered platform since moving to California, where two-cycle gas models are banned. I’ve also observed what features and models my landscape crews prefer, since they use this tool daily.

I used this knowledge and familiarity to research the most popular brands and identify those that met my criteria for best overall, best budget, best battery-powered, and best for a large yard. I also checked out brands I was less familiar with to see if there were new products and innovations available.

String trimmer FAQs What’s the difference between battery weed eaters and gas weed eaters?

The only difference between a battery and a gas weed eater is the power source. They both have similar cutting widths, string diameter and accessories. But it is important to remember that gas trimmers typically have more cutting power than most battery trimmers. Run times are also longer with gas, and there is no need to wait for a battery to recharge. Another important difference between the two types is noise. Gas-powered weed whackers are much louder than battery-powered, and two-cycle gas trimmers are even louder than four-cycle trimmers.

Is a string or blade better?

Choosing between a string or a blade trimmer depends on the type of plants to be trimmed. For fields with tall weeds, a blade is preferred because it cuts through tough stems more effectively than a string line. Some blade trimmers can even cut through woody stems with no problem. String trimmers are best at knocking down soft-stemmed weeds and trimming lawns. They also let you safely trim near structures and walkways without damage.

Is there a difference between a weed eater and a weed wacker?

Nope! These machines go by many different names: weed eaters, weed whackers, string trimmers, weed trimmers, and sometimes even by different spellings (weed whacker vs. weed wacker). The bottom line is that they are all the same basic tool that uses rapidly whirling string (usually made of nylon) to cut weeds and grass where a mower typically can’t reach.
