That is an awesome unit.
This weekend I pulled the trigger on a Bad Boy as well but a lower end unit. Got the 54" ZT Elite with the Kawasaki engine. It has a suspension and I also have a bumpy lawn to mow so that was one reason to get it. Seems like a lot of bang for the buck.
I have a lot less to mow...about 2 acres. It should cut my mow time by 50% compared to the 48" rider I have been using. At 70, it will be my last mower. Almost went with an even less expensive option but saving $1500 over the next 15 years is not that important to me.
The way our government is pissing away money, that $1500 may not buy much down the road anyway...lol.
