Take a standard Honda HF2620 lawn tractor, add a 1000 cc Honda Firestorm engine, and top it off with the steering rack from a Morris Minor: this is Honda’s Mean Mower.

Honda UK, in partnership with the Honda-powered BTCC title-winning Team Dynamics, has developed one of the most insane vehicles with four wheels and an engine. The Honda Mean Mower has a power-to-weight ratio of 532 hp per tonne (this is metric folks), uses a sequential transmission, is powered by a 1000 cc motorcycle engine, and has the ability to go 130 mph (that’s as close as makes no difference to 210 km/h).

Underneath the unchanged skin is a completely fabricated chromoly steel chassis and the lawn machine still has the ability to cut grass, though the clipping bag is now used to house the fuel tank, oil cooler and a secondary radiator.

No word yet on when Honda will create a 87 hp rake to clean up the mess left behind.

Introducing Honda’s New Fire Spitting 1000cc 109HP…… Lawn Tractor! #meanmower

Innovation, pushing boundaries and creating extraordinary pieces of engineering is what Honda is all about. So when Honda (UK) teamed up with their title winning British Touring Car Championship (BTCC) partner, Team Dynamics, to create what is believed to be the world’s fastest lawn mower, you know it’s going to be special.

Meet Mean Mower…
The brief for Project Mean Mower was very straightforward. To build a super-fast mower which retained its original look, but, crucially, could still cut grass. The staggering result is a machine capable of reaching an estimated 130mph and 0-60 in just four seconds with an ear splitting roar reaching 130db.

Mean Mower has already been put through its paces by reigning BTCC champion and Honda Yuasa Racing driver Gordon ‘Flash’ Shedden – check out the video here http://bit.ly/MeanMower

The Birth of Mean Mower
Team Dynamics re-engineered a Honda HF2620 Lawn Tractor from the ground-up, adding an all-new fabricated chassis, custom-made from 4130 chromoly, to provide a strong, safe but very light platform. A 1000cc engine from a Honda VTR Firestorm was used, along with a bespoke suspension and wheels from an ATV.

Every effort has been made to retain as much of the look of the original mower as possible. The cutter deck was custom-made in fibre-glass, to reduce weight, while, in a stroke of pure genius, the grass bag provides a happy home for the fuel tank, a high capacity oil cooler and a secondary water cooling radiator.

The ability to still cut grass was also a key element of the brief, and the super-fast mower still can, admirably, thanks to two electric motors on the cutter deck, spinning 3mm steel cutting cable at an incredible 4000rpm. The mower can cut grass at around 15mph, more than double the flat-out speed of the original HF2620 from which it is derived.

Based on feedback from Honda Yuasa Racing drivers, three times BTCC champion Matt Neal and reigning champion Gordon Shedden, the mower features a custom-made paddle shift six-speed gear system. Additionally it has a custom-made Cobra sports seat, a Scorpion exhaust system and a steering rack taken from a Morris Minor.

The result of this remarkable feat of engineering is a lawn mower set-up and geared to achieve a top speed in excess of 130mph, weighing just 140kgm, producing 96Nm of torque and an incredible PTW ratio of 532bhp/tonne. In testing to date the mower has topped 100mph on a circuit, belting out a remarkable 130db at three-quarter RPM and 98db at idle.

Kate Saxton, Manager – Corporate Affairs, at Honda (UK) comments:
“Honda is a great believer in collaboration, pushing boundaries and creating extraordinary pieces of engineering. This project provided the perfect opportunity to not only highlight the breadth of our product offering but to also promote our sporty heritage and support our reputation as an innovative company. Above all else, we love a challenge!”

Safety is paramount to the project, so every effort has been made to make the mower stable and secure. To achieve optimum balance ATV wheels have been used – ideal because ATV racing is held on rough off-road tracks. Super-soft tyres ensure optimum grip and excellent handling on the tarmac.

Every effort has been made to use Honda parts, where possible, including brakes and several motorcycle components. Almost everything else has been custom-made by Team Dynamics and its partners.

Team Dynamics Team Manager, Pete Crolla, concludes:
“One of the key challenges is that this has never been done before, to our knowledge, and so there are few learnings to call upon. From an engineering perspective, retaining the look of the mower, and the ability to still cut grass were the biggest challenge.”
