like in NASCAR racing. The sport was taken to the United States by the makers of a petrol stabiliser called Sta-bil, who had visited the UK and witnessed a race meeting. It has since grown to have multiple national organizations, including the U.S. Lawn Mower Racing Association and the American Racing Mower Association. Lawnmower racing should not be confused with go-karting, wherein lawn mower engines have often been used, especially amongst the amateur participants in go-karting. Lawn mower racing is based firmly around the use of both engines and chassis from regular model mowers. Also, where go-karts are exclusively raced on relatively flat surfaces, lawn mowers can be raced off-road. In North Carolina Since the summer of 1984, the North Wilkesboro Rotary Club has played host to lawnmower racing at its Wilkes County Agricultural Fairground facility. Sanctioned by the Allegheny Mower Racing Association, oval track racing on the dirt is reminiscent of the beginnings of stock car racing at the North Wilkesboro Speedway and the birth of NASCAR. Crowds have grown from a few hundred to gatherings of thousands on several Saturday nights from June through September. The Wilkes County fairground site is said by many participants to be the premier facility within the AMRA circus. Proceeds from the club's lawnmower racing events are distributed throughout the year to the many activities supported by the North Wilkesboro Rotary Club. The club contributes to most local United Way agencies, provides annual scholarships to local high school students, holds a Christmas Party for the county's foster children, while also supporting worldwide relief efforts of Rotary International. In Missouri Starting in the spring of 2013 lawn mower racing has been held every other Saturday in Patton, Missouri. Racers from all over Southeast Missouri and parts of Arkansas come to the Patton Saddle Club to race their racing machines. The races are held due to a merging of the Southeast Missouri Lawn Mower Racing Association (SMLMRA for short) and the Patton Lions Club. Hundreds of fans come to watch the races at only five dollars a car load. All proceeds are taken care of by the Lions Club. Racers vary in age from six to seventy in five separate classes. Kids (6–12 years old) run in the Youth Class. Their mowers are limited to a stock lawn mower engine with a governor set to no more than 3650 rpm and a 10:1 gear ratio.
