The 8-in-1 all-purpose Worx Aerocart (WG050) features unrivaled versatility, effectively eliminating the need for a traditional wheelbarrow. The all-new Wagon Kit (WA0228) takes those capabilities to the next level by transforming your Aerocart into a wagon cart/hay wagon, complete with a resting seat, tool tray and cup holders. The Aerocart Wagon Kit’s (WA0228) included Garden Seat provides you with an ideal resting spot when it’s time for a break. It also doubles as a seated work position for tasks such as gardening, painting and sanding. Load up your Aerocart (WG050) and let the wheels go to work for you. When used in Wagon Cart mode, loading/unloading materials becomes easier and you won’t need to worry about balancing your load on one wheel. Need to haul oddly-shaped materials that won’t fit in a traditional wheelbarrow. Need additional space for more objects. Simply lift the extension arms and insert the Aerocart handles into the Hay Wagon Clips to maximize your capabilities. Please Note: The Worx Aerocart WG050 is sold separately and not included with the Wagon Kit Attachment.

Never pay for the cost of spools over the lifetime of your qualifying Worx trimmer. That’s how excited we are about the DNA2 DoubleHelix cutting line. We want you to have as many as you need, and to tell others about its aerodynamic design, which makes for cleaner cuts. Sharper cuts encourage growth, so you’re going to have the healthiest lawn on the block. Each spool comes pre-wound, so you can just pop it into your trimmer and get to work. Each spool contains 10 feet of string, and so each 6 pack we send has 60 feet of line. Trim and edge as much as you want, we’ll make more. This DoubleHelix line is only 0.065” thick yet has over 100 lbs of tensile strength. That thin diameter means it can be spun faster, and its solid construction tears through thicker grass. These spools are compatible with over 25 of our 20V and 32V trimmer and edger models. It even works with one of our 40V trimmers. So go ahead, order more spools, you’ve earned them.
