I'm a little behind here and trying to catch up. Please bear with me.
In the other thread you wanted to mow three acres, and not have to make multiple passes. You found a tractor that several of us suggested you avoid because it's a large tricycle. You were also going to buy a bush hog. I made the comment that the bush hog would do the job, but wouldn't be pretty. And I asked if you wanted/needed pretty.
Then you found another tractor and started this thread. Smaller and lighter than your previous choice, the Kubota will do a better job, but is still quite large for a dedicated mower.
You express your desire for a finish mower of some type instead of the bush hog(I guess you do want/need "pretty"?). That's fine. Plenty of options to size for the Bota. Then you mention that the grass gets to 2 feet tall. Red flag!
I'm sorry to be the one to say it, but I can't name a single mower that will take 2ft tall grass and turn it into anything that'd pass muster as "pretty". There's just to much material. Maybe get something with a MMM and a bagger, but you'd be filling and emptying the bags a lot. And constantly battling clogs. Or a mulching deck and go really slow?(Never used a mulching deck, don't know if that'd work or not.)
I have to at least partially agree with dick, the solution is not letting the grass get so high. Tractor or zero turn, that's your choice. If you want a tractor with a finish mower, then I wish you luck on your search, but you'll still need to mow just as often as if you had bought the zero turn. And it will take longer. If you want to do one and done, then get a bush hog. It won't be a fairway at St. Andrews, but it will be knocked down.
