Behind a start line in a field in southern England, a group of drivers rev their engines, raring to open the throttle on noisy machines more used to cutting grass than racing across it.
The racing track is a grass field where mowers compete with their blades removed for safety reasons.
There are three racing groups depending on the type of the machine: The traditional ones with attached seat, the Lawnmowers which look like a buggy, and the lawn tractors.
"It's a little unusual, it's not like jumping in a car and turning the wheel and peddles and gears," said Dean Fuller, British Champion on the wheel-driven variety, at the season's first meeting in Surrey.
"You have got to learn how you lean, how you brake, the different types of surfaces ... So it really does take three or four years before you get the hang of (it)."
