This is a lawn mower designed in the 1950’s by Anzani an engine manufacturer. The Art Deco style Mower was one of the first mowers specifically designed as a ride on machine for the domestic, as opposed to professional, market. The mower had a very basic design with a streamline appearance.  The roller of the rear chassis section supported and provided stability for the rider who sat on a bicycle seat, this layout gives the impression of a tricycle, especially on the Lawnrider where the front roller was very narrow, however reasonably stable.
