I just bought my first ztr before the snow hit, best buy I ever made. I was torn between the dixie extreme mowchine(generac), and the supreme efi 28hr. kohler. At first I was sold on the idea of going 15mph with the extreme but carberator was running to lean. After a few nights of no sleep, I decided to go with the 28hr fuel injected Kohler 60" 11mph. I was wondering if any of you guys had any experances with dixie chopper's generac motors.
