The Worx Nitro WG186 40V PowerShare Cordless Attachment-Capable Driveshare 15” String Trimmer was designed to give any lawn or property professional-looking landscaping results. Driveshare is the Worx system of lawncare attachments (sold separately) that turn your String Trimmer into a Hedge Trimmer, Brush Cutter, Pole Saw, or an Edger. Save money and space by purchasing the Driveshare system rather than 5 separate tools. You gain the capability of an entire lawncare detailing system when you start using Driveshare. But what truly sets the Nitro 40V String Trimmer apart from your average battery-operated trimmer is its gas-like performance. This isn’t your standard 20V cordless trimmer. We’ve doubled its potential, and when paired with two high-capacity PowerShare PRO batteries, you’ll enjoy power comparable to gas-powered trimmers without the expense, fumes, or mess. The cutting line length is 20 ft., and the line diameter is 0.095 in. The specs of this String Trimmer are comparable with commercial-grade outdoor power tools. The Driveshare attachment trimmer system was engineered to provide functionality that’s perfect for property owners with larger, more complex lawns.
