The 9 Best Weed Whackers to Keep Your Lawn in Tip-Top Shape, According to Reviews

Also known as string trimmers or weed eaters, weed whackers are endlessly useful tools for keeping your lawn and garden in tip-top shape. A good one will help you trim back not only weeds, but also grass where your lawn mower might not be able to, like up a sharp incline, against the sidewalk, or even around that limited edition garden gnome you just acquired. You can use them to edge along your flower beds, too. There are a few choices to make when shopping for the best weed whacker for your needs, so here's what to consider while making your selection.

In terms of power, they typically come in two main varieties: gas and electric. A gas version offers more power, while an electric model is quieter, more lightweight, and generally easier to use. Electric, battery-powered trimmers are a good option for home use, because they're more maneuverable than gas options or corded electric models.

You can also choose between a curved or straight shaft. The curved shafts can feel better-balanced and easier to use but may have less torque, while the straight ones will have a longer reach and can more easily do double duty as edgers. A straight shaft also puts less strain on the interior mechanisms of the weed whacker, and is more likely to be able to handle different attachments.

You'll also want to look for good handling and a weight that won't strain your lifting capacity, as well as good battery life if you're choosing a battery-powered pick, of course. It's also useful to have an easy way to replace the string, as well as a wide guard to keep you from getting smacked by high-speed grass trimmings.

Best Echo Weed Whacker

Another gas-powered option, the SRM 225 is billed by Echo as its most popular straight-shaft gas trimmer.

Best Value Weed Whacker

Get the benefits of Black+Decker’s expertise at a budget price point. Reviewers express concern about the rate at which this trimmer goes through string due to its auto feed system and the fact that its port can’t fit a three-prong extension cord, but they like its low, easily maneuverable weight and powerful cutting abilities.

Buy It: Black+Decker ST86000 String Trimmer & Edger ($47, Amazon)

Best Corded Weed Whacker

More than 9,000 Amazon reviewers have given this Greenworks model a 4.5-star average rating, which is extra impressive given its low price tag. Using a corded model means you can run as long as you’re plugged in, and you carry slightly less weight thanks to the lack of fuel tank or battery pack. Just make sure you’ve got an extension cord long enough to reach the edge of your lawn.
