Το Honda Mean Mower είναι πλέον και με την βούλα το ταχύτερο τρακτεράκι γκαζόν του κόσμου, μιας και στο κέντρο δοκιμών IDIADA Proving Ground στην Ισπανία, ο Piers Ward του βρετανικού Top Gear Magazine έπιασε με αυτό τα 187,6 χλμ/ώρα, σπάζοντας το προηγούμενο ρεκόρ των 141,34 χλμ/ώρα το οποίο είχε σημειωθεί το 2010.
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.
Από την άλλη, δες αυτό το καροτσάκι-scooter το οποίο φορά έναν δίχρονο βενζινοκινητήρα που συνδυάζεται με έναν ηλεκτροκινητήρα και είναι ικανό να πιάσει τελική ταχύτητα έως 131 χλμ/ώρα σύμφωνα με τους δημιουργούς του.
HONDA’S 1000CC 109HP MEAN MOWER HAS BROKEN A GUINNESS WORLD RECORDS™ TITLE FOR THE FASTEST LAWNMOWER!
It’s official – Honda’s 1000cc 109HP Mean Mower has broken a Guinness World Records™ title for the Fastest lawnmower!
Honda (UK)’s Mean Mower (#meanmower) has officially broken the GUINNESS WORLDs title for the Fastest lawnmower, averaging 116.57 mph to break the previous record by almost 30mph. See the video here: http://youtu.be/DFo7ztlMlmg
The successful GUINNESS WORLD RECORDS attempt took place under the watchful eye of a GUINNESS WORLD RECORDS Adjudicator at the IDIADA Proving Ground, in Tarragona, Spain, on Saturday 8th March 2014. Behind the wheel was Piers Ward of BBC TopGear Magazine, who had previously achieved a fastest speed on Mean Mower of 87mph. At around 4.20pm CET on the 2000km North Straight at IDIADA, Piers eclipsed the previous record of 87.83mph, set in May 2010.
The speed was measured through a 100 metre speed trap, overseen by official timers, Timing Solutions Limited. To meet Guinness World Records regulations the mower had to record the same run, in both directions, within an hour – with the average speed taken of these two runs. Additionally, to qualify for the record it needed to cut grass and to look like a lawnmower; both of which it did successfully. With all of these criteria met, the GUINNESS WORLD RECORDS Adjudicator officially declared the success of the record attempt just before 6pm CET on Saturday 8th March.
Ellie Ostinelli, PR Communications Manager for Honda (UK) comments: “The original brief for Mean Mower was to create the world’s fastest lawnmower – and now it officially is, by some distance! We are all delighted to hold a GUINNESS WORLD RECORDS title and we’d like to thank everyone who was involved in what has been a challenging yet incredibly exciting project.”
The idea for Mean Mower was to demonstrate Honda’s sprit of innovation, its motor sport heritage, and that it makes more than just cars. Mean Mower was designed and built in the UK by Honda (UK)’s British Touring Car Championship (BTCC) partner, Team Dynamics. The team 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 was 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 2012 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 140kg, producing 96Nm of torque, an incredible PTW ratio of 532bhp/tonne; and an estimated 0-60 of just four seconds.
Safety was 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. Additionally, every effort was 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.
