Around here there is no one overwhelming choice for the commercial mowers. I do see mainly Bad Boys, Scags and ExMarks on the trailers. My dad has a Kubota ZD28 with the 72 Pro deck. He uses it to mow his nearly 9 acre yard. I know the dealer experience can make or break the ownership experience. One of the wheel motors went out when his mower was roughly three years old, I don't know how many hours were on it at the time. The dealer came and picked up his mower, and left him a similar one to use. When the bad wheel motor was diagnosed, the dealer replaced the ENTIRE hydraulic system and they said there would be no way to be absolutely certain all the metal shavings were flushed out of the system. That was 6 or 7 years ago and dad has not had one problem with it since.
