I have a Scag Wildcat with a Kohler on it and have had zero problem out of it. It is now 8 yrs old and cuts 3 acres every week or other week. My dad has a Exmark and he borrowed my mower to cut some rental property he has. The next week he went and bought a Scag. The ride is completely different and tons of power but this is just my opinion, not trying to knock Exmark but just giving out info.
