Looking for some advise and opinions between these 2 ZTR's. I have narrowed my search down to these 2 used mowers. The 21/48 Citation is a 2008 model, 110 hr Briggs and the 25/60 CC is also a 2008 with 170 hr Kawasaki. I mow about 1.5 acres weekly and occasionally my neighbors 2 acre yard. I have done my research and they both seem to get high marks and both have their pros and cons. I can get either one of these for about the same money so any advise would be appreciated. Thanks!
