I got to drive one of these prototypes today. This mower was so Damn fast it was almost to fast, beleive it or not. 15 MPH standing, it was amzing. It had a 27 hp Kaw, spring loaded stand on plat form so rough terrain should more comfortable. On this model they had different gas tanks, and exhaust than what will be on the finished model. My only real complaint is the introductory price of 10K. If they can do better on the price i will definitely get one. Has anyone else tried one of these yet?
