KEEP AN EYE ON YOUR OIL LEVEL!!!! Just a heads up, I got a '12 x series with the same kholer engine. From day one engine had been using oil to the point every 50 hours had to add half a quart. 240 hours into it and was fed up took into the dealer kholer looked at it and replaced the engine. Now into '13 season and guess what still using oil, I thought I was doing something wrong. Talked to the service department and found out that they sold two of those engines one being mine and have replaced both mine and the other persons engine, same reason..... Love the mower its a tank but something is wrong with the Kholer 980CC or 999CC... I hope they have fixed the problem. Good luck with the mower.
