Dealer will take my Z500 20/52 with 300 hrs or so on it for a demo Z500 23/60 for no monyey out of pocket. new one has 49 hrs on it and a full 2 yr warranty. Wife and friends are calling me stupid for not already doing it. My big fear is a 60inch cut will just be to big. for those with 60s do you have problems on smaller lawns? I just dont want to get it to find out it is way to big. My 52 seems about perfect.
