I have been talking to a few local dealers getting ready to demo a machine. I am wanting to demo a 52" floating deck hydro walkbehind. 1 dealer I have been to says his sales are mainly belt drive, that he is old school and doesn't like hydros. 2 Dealers said they sell a good amount of that machine. 1 dealer said he don't sell many mowers in that combination of deck/drive system. He says that I should just spend the extra 2500 and go with a 52" Z Rider. I reminded him that I was running a 52" WB some of last season and he says that I am one of the few people that he knows that runs a WB that size. Should I consider a 52" WB or should I go with a Rider? Some of my larger lawns are a bit bumpy and a few are hilly where I would not be able to use a rider.
