The lawn-cutting implement in question is Honda's latest, greatest and nuttiest. Dubbed the Mean Mower, it features a 999-cc four-cylinder from a Honda Fireblade motorcycle that produces 189 horsepower. It's connected to a six-speed manual transmission and Honda will attempt to hit 150 mph with it at a later date. An older version of the Mean Mower hit 117 mph. There's also no suspension, so here's to the poor guy who suffered for our collective amusement.
Now, we're not entirely sure why the Mean Mower stops in the middle of its hillclimb. Perhaps the aforementioned driver spotted some road-lining grass in need of a trim and pondered letting the Mean Mower do its more natural thing. After all, it does have functioning carbon fiber grass-cutting blades.
Look for more videos of interesting vehicles racing up the Goodwood hillclimb. They're bound to be cars, though, and will probably not be as amusing as a lawn mower. With or without bananas.
