I have a question soon or at the end of the year i WILL be buying a hustler..nothing in the world could change my mind after seeing what a good job you do on here and with adressing everyones problems as quickly as possible..it WAS between exmark and hustler..well compare hustlers forum to exmark and hustlers deck to exmark hustler fixed the problem quickly exmark is still scratching there heads...hustler wins both! Back to my original question is the 27 kohler underpowered for a 60" Super Z. Seems like some people may think so and if so how bad..everyone says look at the 28efi but money is a object! Right now i have a 27hp with a 52" deck (toro) and i have never really bogged it down so how underpowered can a 60" be???
