It's powered by a 4.8-amp electric motor that spins the line at 9,500 rpm. An automatic line-feed system eliminates the need to bump the trimmer against the ground every time the line breaks.

Here are both. Black & Decker's Grass Hog automatic feed string trimmer/edger is a great buy for the gardener who needs to whack weeds regularly. Its powerful 4.2 amp motor provides superior trimming of heavy weeds, grass, and overgrowth. You can use this trimmer to whack the most unruly weeds or to simply maintain and trim long grass and sparse dandelions. The 12-inch cutting path and 10,000 rpm get the job done fast. No wonder it's called the Grass Hog! This Black & Decker is easy to maneuver and can be used to trim weeds in hard-to-reach places where other trimmers fail. It will also challenge thicker weeds, but watch out for vines, which can get tangled up above the cutting spool., Black & Decker definitely keeps the consumer in mind by offering convenience and comfort while trimming. Perhaps the best feature of this trimmer is its auto-feed string: you'll never need to bump the trimmer head while trimming to get more string (though you may need to refill the string more often). An adjustable, textured top handle provides firm gripping and maximum control. Weighing about 6 pounds, this string trimmer is not too heavy, even for longer jobs. We like that the vibration in your hands after a long trimming job is minimal and that this trimmer doubles as an edger. The Groom 'N' Edge button rotates the trimmer head 180 degrees to convert the trimmer to an edger and back again. In seconds, you can turn the head, and you'll hear the snap when it's in place. An edge guide provides precise trimming and edging around sidewalks and driveways and does a good job of keeping you at a safe distance from rocks or even the side of your deck or house. The cord retention system prevents accidental cord disconnection, which is especially useful when you're hard at work in the yard and the cord is extended., This string trimmer, as well as most other electric trimmers, is best suited for small yards that are accessible with an extension cord. Because electric trimmers are generally lighter and more comfortable, they are easy to handle. If you're looking to whack unruly weeds on your otherwise well-maintained yard, this electric trimmer is a less-powerful yet sufficient alternative to more expensive gas-powered trimmers. Be sure to wear hand, eye, and foot protection when operating any trimmer. A 30 day no-risk satisfaction guarantee and full two-year warranty are included.
