A roller (6A), located in a rearward chamber in the body, is mounted in openings (23) in the sides of the body and wheels (5) are mounted in openings (24) at the front of the body.

  • Patent number: 4574568
    Abstract: A collecting box for collecting debris from a garden tool, for example a lawn mower or a lawn raker, has a lightweight, self-supporting collecting box body and, on each side of the body, a tubular fastening member for fastening the collecting box to the garden tool. The fastening members extend at least one third of the way along the sides of the body with a view to preventing the body being subjected to high stresses, and the ends of the fastening members project from the body and can be inserted into sockets in the tool. An intermediate length of each fastening member is exposed to provide a handle for carrying the box.
