The best weed wackers and string trimmers are must-have garden tools because they make it easy to keep your lawn neat by cutting grass and weeds in places your mower can't reach. They’re great for tidying up edges and corners, making your yard look well-kept without much hassle.

The best weed eater we've tested is the powerful Kobalt KST 2580-06, which works like a gas-powered plaything, but without the fumes, racket, and weight. But, if you prefer one that's light and quiet, not to mention a good value, check out the Dewalt String Trimmer DCST925M1.

If you’re looking for the power of a gas string trimmer without the fumes, racket, and weight, then the Kobalt 80-volt is the one for you.

Best Weed Wacker and String Trimmer
Kobalt KST 2580-06

If you’re looking for the power of a gas string trimmer without the fumes, racket, and weight, then the Kobalt 80-volt is the one for you. While all of the best weed wackers we tested cut through most reasonable underbrush, the Kobalt electric string trimmer is one of the few that cut through everything in one pass. Long grass, bittersweet vines, small saplings, even bamboo—it shredded it all.

All that power and the massive 80-volt battery that drives it doesn’t seem to come with additional weight or balance problems. At just over 11 pounds, the Kobalt 80-volt string trimmer is right in line with the rest of the lawn care tools we tested. In terms of balance, it is easy enough to get in and around objects while keeping a level cutting height. It is also maneuverable enough to turn on its side to edge around driveways or walkways, making it a great choice for landscaping pros and novices alike.

This said, this is a large weed wacker, not meant for tight spaces, so if most of your work involves tight quarters, then you may want to choose a smaller option. If you’ve got a lot of areas to cover, however, then the Kobalt 80-volt string trimmer is a great choice at a solid price.

Pros

  • Powerful

  • Well balanced

  • Versatile

Cons

  • Large

The DeWalt is the lightest and quietest of the larger weed wackers that we tested.

Best Value Weed Wacker and String Trimmer
DeWalt DCST925M1

As the lightest and quietest of the larger weed wackers that we tested, the DeWalt 13-inch cordless trimmer is very easy to use. The low weight only comes with a minor sacrifice in power. While it didn’t cut through thick underbrush quite as quickly as some of the others, it could get through some heavy-duty growth, particularly for the relatively low price.

This said, the design of the spinning cutter head lends itself to getting bound up. Several times while I was cutting through longer growth, particularly bittersweet vines, strands wrapped around the spinner head, slowing or even stalling the trimmer. This was the only weed wacker where this happened.

Another drawback of this trimmer is the very small shield. My legs were under constant assault from clippings, dirt, and rocks, far more so than any of the other devices I tested. However, if you’re wearing jeans like you should be, then this shouldn’t be a problem.

The DeWalt trimmer works with a much broader set of battery-powered tools. If you’re already invested in the DeWalt lineup, then this is a great trimmer for the price.

Pros

  • Lightweight

  • Quiet

Cons

  • Binds up easily

  • Small shield

This Ego string trimmer is the best battery-powered option we've tested.

Best Battery Weed Wacker and String Trimmer
Ego Power+ ST1500-S

At 56 volts, the Ego is one of the most powerful battery trimmers that we tested. And it shows. This is another machine that cuts through just about anything without hesitation. When it comes to pure cutting power, it’s comparable to the Kobalt.

That said, when the string starts to fray and shorten, there’s a much greater reduction in cutting power than the other weed wackers. This isn’t a huge problem—tapping the machine on the ground to extend the string is easy enough—but it does make for a few moments of frustration as you’re working.

The other, and more important, issue with the trimmer is the balance. I never found a comfortable position on the shaft for the handle. No matter how I held it, the cutter head kept dipping forward, making for uneven trimming and a pretty ugly end result in a lot of places. A previous reviewer with a smaller body frame had tried this model and found it well-balanced, so this may be more connected to my body size and shape than the design of the weed wacker.

Pros

  • Powerful

Cons

  • Quick reduction in cutting ability

  • Unbalanced

If you need the best gas-powered string trimmer, the Husqvarna 128LD is our favorite.

Husqvarna 128LD

This is an absolute monster of a trimmer. If you put it in front of something, it’ll cut it. I brought this into my backwoods to cut back some ivy and underbrush, and I didn’t even really have to pay attention to what I was cutting. Everything I touched just disappeared. For heavy-duty trimming, it’s hard to beat the reliability of a solid gas weed wacker, particularly since you don’t have to worry about battery life.

This said, there are two significant drawbacks to all of that power—volume and fumes. Like all 2-cycle engines, the Husqvarna is loud, and it puts out a significant amount of exhaust. If you can live with this and need more power than most electric trimmers will give you, then the Husqvarna is an excellent option.

Pros

  • Professional level power

Cons

  • Gas-powered

  • Loud

If the only thing that matters is raw power, then a gas trimmer is what you’re looking for, and the Echo is a solid choice. Just about anything it touches gets cut. It’s actually a case of sometimes seeming too powerful—when I went to cut a piece of bamboo with it, it didn’t just cut the bamboo. It sent the pieces flying about 10 feet. Getting in and around my shed, it’s strong enough that it can damage the wood as well. For most homeowners, a gas trimmer is simply more power than you need.

Beyond the question of power, this had a few small quirks. First is the balance. To use it comfortably, the motor compartment rests against my elbow. And that gets hot. Not painfully hot, but enough to notice. The second drawback is the volume. Gas trimmers are very loud, and the motor only sits about two feet from your ear. Finally, like all 2-stroke engines, this one is very smelly, especially on startup.

Pros

  • Powerful

Cons

  • Gas powered

  • Too powerful

  • Uncomfortably balanced

How We Tested the Best Weed Wackers and String Trimmers

The Tests

We put the trimmers to work on both short and tall grass, as well as tougher roots and weeds, seeing how quickly, efficiently, and consistently they tackled each job and maneuvered around edges and obstacles without running out of battery or breaking a string.

We assembled each trimmer, taking note of how clear the manual instructions were, how much set-up was required, and how easy it was to install a new string. We looked at safety features, such as locking power switches and trimmer guards.

We also assessed how comfortable each unit was; if the weight was evenly distributed from top to bottom, if the controls were accessible, where the handles were situated, and if the shafts could be adjusted for better reach.

What To Know About the Best Weed Wackers and String Trimmers

While a gas string trimmer is generally preferred by professionals, an electric or batter-powered weed wacker (pictured here) makes more sense for at-home use.

While a gas string trimmer is generally preferred by professionals, an electric weed wacker makes more sense for a small yard and at-home use. Electric weed wackers come in corded or battery-powered versions, each with their own pros and cons, depending on what you're looking for. In addition, be sure to keep an eye out for amperage—averaging between 3.5 and 7.5—which generally affects the price, and assess how much power you really require for the size of your space.

Types of Weed Wackers and String Trimmers

Corded trimmers are generally lightest and least expensive, and they start with the push of a button. Unfortunately, they almost always require extension cords, which can be frustrating to wrangle while you’re working.

Battery-powered models offer the mobility of gas, without pull-starting, fueling, and fumes, but are heavier and more expensive than corded, and have a battery life with a run time between 30 and 60 minutes before needing a recharge.

As far as cordless trimmers, you'll want to look for options with a top-mounted motor, which tend to be better balanced (making them easier to handle) than models with motors mounted down near the cutting line.

Choosing The Best Weed Wacker

Lightweight, balanced, and low vibration models will always rate higher on our list since they make maneuvering around the yard easier. The ideal model string trimmer will also come equipped with spools, which make it easy to load a new line.

Whether you opt for a corded or cordless weed wacker, selecting a cutting swath (10 to 16 inches) that makes sense for what range you need is important in setting yourself up for success. If you're doing heavy-duty work in large areas you'll be better off with a large straight shaft, but if you're cleaning up smaller areas with light trimming a curved shaft is a better bet.

Be sure to select a cutting swath (10 to 16 inches) that makes sense for what range you need.

We also found that thicker strings and dual nylon lines are most effective for tougher weeds and unruly yards, while trimmers with swivel heads assist with creating clean edges and finishes in tune with your ideal landscape design

Choosing between corded and cordless tools isn't something we take lightly. Though it might sound like a simple convenience factor to some, using the right tool is important in getting the job done right, and safely. When it comes to string trimmers quiet motors or engines are obviously preferred, not only because you'll be hanging around directly above it but also to decrease noise pollution.
