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 24km/h (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 2013 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 209km/h (130mph),
weighing just 140kg, producing 96Nm of torque, an incredible PTW ratio
of 532bhp/tonne; and an estimated 0-100 km/h acceleration time of just
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.
