I have a ZG 222 it is a year old. Has 175 hours on it. We run it commercial. It is a pretty good machine. If I had it do all over again to run commercial I wold buy the ZD 221 but the 222 is a good mower.
A dealer about 2.5 hours from me has a few used ones and I'm not sure it's worth the drive. I am having a ferris brought out or demo in a few days. I think the kubota may be the better buy, but with the distance it's going to be tough.
