Competitors have descended on Surrey to take part in the World Lawnmower Championships.
The event is being held by the British Lawn Mower Racing Association (BLMRA) at Pondfield Farm, Alford.
The association says lawn mower racing started in 1973 when an Irishman named Jim Gavin was looking for a cheaper form of motorsport.
The BLMRA still sticks to its origins as a non-profit making organisation, with any money generated given to good causes.
