Honda’s U.K. division joined up with its British Touring Car Championship partner Team Dynamics and tore apart a Honda HF2620 Lawn Tractor before revamping the whole thing with a custom-fab chassis and a 1000cc engine from a Honda VTR Firestorm motorcycle. For good measure, the team took the suspension and wheels from an ATV to cope with the extra grunt.

Of course, this is a lawn mower we’re talking about. Guinness, sticklers that they are, required that the Mean Mower be able to actually cut grass. So Team Dynamics created a custom cutter deck out of fiberglass and installed a fuel tank, high-capacity oil cooler, and secondary water cooler for the radiator in the mower’s grass bag to preserve as much of the look of the original tractor as possible.
