After 14 years of using Dixie Chopper I went and bought the new Exmark XS with the 31 HP. All I can say is WOW what a cut. The only reason I never bought an Exmark before was the ground speed going from one house to another was way to slow. With this 31 hp engine now it goes almost as fast as the Dixie. My other Dixie was the 28 hp Extreme.
