I currently have a toro 253 teamster with a 62" deck and 23 hp Kohler. It has been giving me some problems and I am thinking about trading it. I would like to get a 52" cut with at least 23 hp. I have thought about getting a top of the line hydro floating deck exmark or scag. Will the walk behind be as beneficial as a rider with the same deck size? I'm also trying to get rid of some debt as well.
