Might not be a true zero turn, but should offer a pretty comfortable ride. Mows a 16 foot swath.
State bid on one without a cab was around $75,000 2 years ago when the city was looking at getting a replacement. With the cab, I imagine you would be looking at 6 figures. There would need to be a lot of yard to mow to justify that.
We have a toro zero turn with a 60' deck. I like it.
