The WORX WG157E Cordless Grass Trimmer functions as both a trimmer and an edger. This lightweight tool easily converts from a trimmer to a walk behind edger in seconds, requiring no additional tools. The WG157E features a single line auto feed system, ensuring easy use, fast trimming, and extended running time. Its long shaft design allows for comfortable trimming in awkward or hard to reach areas. A built in Flower Guard helps prevent damage to flowers or ornamental lawn fixtures. To convert, simply turn the head 180 degrees to switch from trimming to edging mode.
