Any input? I have demoed the Trimstar so I know what that's all about...good and bad. Have not demoed the Viking as I am just now considering it in place of the TTHP's. I like the ECS concept and everything behind Exmark. My only concern is the 15hp Kaw on a 48 deck. Sure I can demo, demo, demo but in late july a 13hp Kaw would probably cut fine. And why dont they make a fixed deck 48" w/ 17hp Kaw anyway. I know this is a poor comparison but my Encore 48" belt drive has a 15hp Kaw and it bogs down from time to time. Will I be able to run a sulky at an efficient pace with this mower? Any opinions from other Viking owners or those that have used would be greatly appreciated. PLEASE!
