Η Honda μαζί με το βρετανικό Top Gear Magazine κατασκεύασαν το Mean Mower, ένα HF2620 τρακτεράκι του γκαζόν το οποίο έχει θεωρητική ταχύτητα 209 χλμ/ώρα.

Μηχανικά φορά το 1.000αρη κινητήρα της Honda VTR Firestorm, ο οποίος αποδίδει 110 άλογα με 96 Nm ροπής. Συνδυάζεται με ένα 6-τάχυτο κιβώτιο με paddles στο τιμόνι, επιτρέποντας στο τρακτέρ να κάνει θεωρητικά

τα 0-60 μίλια/ώρα (0-96 χλμ/ώρα) σε 4 δευτερόλεπτα.

Φορά ένα σωληνωτό σασί, νέα ανάρτηση και μια ειδική θήκη από πολυεστέρα. Ζυγίζει 140 κιλά και διαθέτει δύο ηλεκτρικά μοτέρ που περιστρέφουν τις πάχους 3 mm ατσάλινες λεπίδες στις 4.000 σ.α.λ.

BBC TopGear Magazine and Honda Unleash the Stig on a 130mph Ride-on Lawnmower

LONDON, July 17, 2013 /PRNewswire/ — In response to an as yet untapped requirement for extreme lawn-care equipment, TopGear Magazine has teamed up with Honda to produce just that – the MeanMower.

Loosely based on the Honda HF2620 ride-on, the MeanMower was stripped and re-built by Honda’s British Touring Car experts at Team Dynamics, adding a spaceframe chassis, a 1000cc Honda VTR Firestorm motorbike engine, bespoke suspension and tyres from a racing ATV.

But despite looking like the standard mower, the Honda now produces 109bhp and 71lb ft – making it theoretically capable of zero to 60mph in under four seconds, and a record-breaking top speed of around 130mph. And it still cuts grass.

The mower managed 100.03mph on track at TopGear Magazine’s annual Speed Week event – a tyre-shredding test of 14 of the year’s best performance machines. Watch the Stig drive it here: http://www.topgear.com/uk/car-news/top-gear-magazine-speed-week-2013-7-17

“With the TopGear lawn to mow and a Stig on the staff, it seemed perfectly normal to work with Honda to create this thing,” said BBC TopGear Magazine’s Piers Ward. “Though I have to say, having driven it, I’ve never been so terrified. It accelerates like a rocket and, like any mower, there aren’t any seatbelts.”

Ellie Ostinelli, Honda (UK) said; “Our brief was very straightforward – we wanted a super-fast lawnmower which retained the look of a mower, but above all else, it needed to still cut grass. Honda is a great believer in pushing boundaries…and we love a challenge!”

Team Dynamics team manager Peter Crolla added, “To our knowledge, this has never been done before, certainly using this mower/engine and Stig combination. Our biggest engineering challenge was the need to retain the look of the lawn mower and the ability to still cut grass. The engine’s low weight and exceptionally accessible performance has been the key ingredient for the project.”

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 MowerTeam 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.”
