A modern twist on a classic chore, the Worx 12” – 20V Grass Trimmer and Edger saves you time and money. Switch modes in seconds, so you don’t have to walk back to the garage to grab a separate edger—don’t even buy a separate edger in the first place! Now that you’ve got this 2-in-1, you don’t have to. Twin rubber edging wheels will help make your lines straight and smooth, and allow you to push along easier. As part of the Power Share platform, it uses the same batteries as every other tool, outdoor power and lifestyle product in that family. The adjustable flower guard keeps plants and lawn ornaments safe. Get right up close without worrying about accidentally cutting anything valuable. The 12” cutting diameter is large enough for wide, sweeping passes over larger patches of grass, but narrow enough to make it maneuverable around landscaping features. And the DNA2 DoubleHelix string we use in our trimmers is specially engineered to reduce drag and withstand snapping, so it spins faster with less strain on the motor and absolutely tears through grass for a clean, professional look. At only 5.3 lbs with the battery attached, it’s easy and comfortable to use for long stretches. And without a cord to get caught on, you’re free to roam all over the yard. Battery-powered lawn & garden tools are quieter, cleaner, and more cost-effective than gas. This powerful, modern trimmer & edger has everything you need to get a lawn with a professionally-landscaped look.

We didn't cut any corners with the WORX 22” – 20V Cordless Power Share Hedge Trimmer. The D-Grip Front Handle lets you easily hold it up high, or from any angle. And at just 5.3 lbs you won’t get fatigued trimming your bushes. As part of the Power Share platform, it uses the same batteries as every other tool, outdoor power and lifestyle product in that family. The Dual-Action Hardened Steel Blades slice though twigs and branches so smoothly that it reduces much of the vibration that comes with many hedge trimmers. With a 22” reach you’ll get long, smooth tops and the 3/4” diameter of each blade catches scraggly sticks to the sides. Comes with a charger and a 2.0Ah, 20V Max Lithium Power Share battery you can use to power this or any other WORX 20V Power Share tool.

The Worx 12” – 20V Grass Trimmer/Edger makes it easy to achieve straighter edges along your lawn and driveway and neater areas around trees and bushes and the side of the house. It’s light (only about 5 lbs), simple to use (just pull the trigger and go), and saves you money (rechargeable batteries are more cost-effective than gas or electric weed eaters). Plus, it’s two tools in one. And all you’ve gotta do is pull the shaft and rotate the head to transition between trimming and edging modes. The flower guard prevents you from trimming anything you don’t want to damage, like flowers, plants or lawn ornaments. But it flips up for when you do want to get really close to an object, like the side of the deck. The 12” cutting diameter is wide enough that you can make nice, even passes across larger patches, but still nimble enough to get in-between bushes and trees. The cutting line diameter is 0.065”, which is the same gauge that’s popular among professional landscaping crews. And that line is the specially designed DNA2 DoubleHelix aerodynamic trimmer string. Its unique oval shape cuts through the air and grass with less drag for a faster rotational speed that puts less strain on the motor. And with over 100 lbs of tensile strength, it lasts longer than trimmer string from other brands. This tool is so much more than a weed wacker, the Worx 12” – 20V Grass Trimmer/Edger is a modern machine full of features and performance that make it easy to use, easy to love.

Changing the game of lawn care, one yard at a time, the GT Revolution is 3 lawn manicuring tools in one. Converts almost instantly from a trimmer, to an in-line wheeled edger, to a mini-mower, so you get a professional-looking lawn that’s easier to maintain and costs less time and money. This is so much more than a weed-eater. It’s a Revolution. At less than 6 lbs, and with a telescoping shaft, 7 handle, and 6 rotating head positions, almost anyone can comfortably use the Revolution. The shaft is a full foot longer than the original GT, and the grips are ergonomically designed to give the user a firm handle on each of the three functions. And when you want to switch from trimmer to edger or mini-mower, it’s just a push of a button and a turn of the head. No tools needed. It’s powerful, too! Spinning at 7600 revs/min and running on the same 20V 4.0 Ah Powershare battery that powers our chainsaws, the GT makes nice, clean cuts. The patented Command Feed system gives you fresh line whenever you need it—no bumping or auto-feed. With an extra spool holder right on the handle, if you do run out of line in the field, you can just pop in your extra spool without a trip back to the shed.
