Lawn mowers are not built for speed, but that doesn't mean there isn't room for improvement. A couple of gearheads with too much spare time and a wild imagination came up with the ultimate mower. Start off with your standard Briggs 5hp lawnmower and then strap on a tank of nitrous. After 60 shots, the engine can't take the strain and explodes under the pressure. They try it a few more times with the same results. Somethings just weren't meant to be.
