I have a model 462 on my Scag Super Z. It too has the Kohler 6 hp on it. I haven't had any problems so far with it, better not for what it cost! As for claeaning, bagging, it works real good, am not impressed with the way its mounted though. It also needs a more user friendly throttle control. Has any of the other users had problems with theirs, or modified it in any way? I'm referring to having to turn around and reach over the seat to shut it off when it gets full and starts blowing debris all over the back of your head.<p>Homer
