Promoter John Peck says every Kentucky county fair his Top Dog Promotions is working with wants the mowers.
Peck tells says The Kentucky Enquirer his demo derbies usually have 35-50 mowers.
One Kenton Court Fair official says the mower derbies are very funny.
For safety's sake, the drivers are enclosed in a roll cage and the mowers don't have any cutting blades.
There's no mulching, but plenty of crunching.
