I'm leaning toward to exmark instead of scag ztr, because of the price. I was looking into 52" ztr to tackle some of my new vacant lot accounts. Scag turf tiger is too expensive and i'm not sure about that the tiger cub 48" can handle such rough terrain. But exmark has 52" with ok price. Less than scag. and also reputation. So I decided to go with exmark, but Kohler engine? I heard some good thing about kawasaki engine but nothing about kohler. Does anyone have good or bad experience with either engine? May be some comparison of ex and scag.
