In 2014, Honda's British Touring Car Championship partner modified a HF 2620 lawn tractor and broke the land speed record for mowers, running 116 mph. But only a year later, a Norwegian named Per-Kristian Lundefaret took his modified Viking T6 all the way up to 133.57 mph. Honda couldn't let this stand forever.
The prototype retains a fairly stock look thanks to its front cowl, grass box, and body panels. Even more crucially, this mower can still cut grass, with revisions done to the cutter deck to house the chain running to the rear tires, and two batteries powering electric motors that spin carbon-fiber blades... That's right, it's got carbon-fiber blades.
