The 2 in 1 weed eater quickly converts from a lawn trimmer to an in-line edger lawn tool and back again. Save your money and don't buy a separate weed trimmer and edger. The Command Feed spool system gives you line when you want it at the press of a button. The rubberized wheels provide traction and support for even, professional looking lines when you’re using the string trimmer. The head tilts 90° so you can trim on uneven patches of lawn. The adjustable spacer guard keeps protects the tops of flowers and plants. And at only 5.5 lbs. you can get your trimming and edging done without feeling fatigue from it. 2 powerful 20v Power Share batteries are included with this purchase, which you can use on any tool on the WORX Power Share platform.
