The optional Leaf Catcher is perfect when you need to haul big loads of lightweight, bulky materials like leaves and grass clippings with the Neuton Garden Cart. Made of heavy-duty nylon mesh with a steel frame, the Leaf Catcher extends the sides of the cart to increase the capacity 4 times — for up to 20 cubic feet! Installs quickly without tools, using the pockets built into the Garden Cart frame.
