Has anyone had experience with the 52" 21hp midmax ztr? I can get a really good price on one from a local dealer and am trying to avoid spending the big bucks on an exmark, scag, or kubota. The specks look really comparable to their competitors with the exception of about a 200 lb weight difference. The absolute largest account this would be used for is approximately 2.5 acre residential lawn. I don't expect to have to put more than 150 hours on it per season. Thanks for any help offered.
