Actually it's no different performance wise to a standard "Scott Bonnar" as they don't need much power to cut....but some guy who was into street customising cars for shows decided to wave his magic chrome wand over his mower....
Why....well, who knows...its not as though you would want to actually use it as any worth it had would be lost...and some aspects are less than ideal from a practical viewpoint...
I guess it would be a great centrepiece to a man cave to look at over a few dinks??
