DEWALT is known for quality power tools that work as hard as you do, and their lawn care products are no exception. Weed eaters can make trimming your yard a snap and come with lots of options. String trimmers are the most common and simplest form of weed eater. You can choose gas-powered or battery-powered, corded or cordless, depending on your preference. A lightweight design is always helpful. Although weed eaters are safe to use, they can pose safety hazards by flinging debris, so it is important to wear eye protection while operating. Children should never be allowed to operate weed eaters without supervision.
