LOL! It would be seriously easy for me to get hooked on fast lawn mowers.
I have a first cousin that has been doing racing mowers for years. His latest is a street machine (they dirt-track race them here at times) that he has won a few 100-yard drag races with. Drove it over to my house one day to ask belt questions. I followed him back to his house, since the drive belt was giving out (finally did about 4 blocks from his house) and it would go 25 mph in third (of four) gear, medium RPMs...
...scary fast!
