I’ve been in the lawn maintenance, landscaping business for over 20years. I’ve always used Exmark of Toro for my commercial zero turns. If I were you I would buy a commercial mower with a Kawasaki engine. In my opinion they are the best z engine hands down. I won’t consider buying a Z unless it has a Kawasaki engine. If you do that and your only cutting your own personal property and you do the regular maintenance on it, odds are you will never have to buy another one. Good luck.
