My BIL just went through this decision process and bought an LS XJ 2025 with the MMM(mid mount mower. He has 3 acres. He bought the tractor with MMM over a ZT because he wanted to do more that just mow. He is completely happy with his tractor and feels it is sized correctly for his 3 acres.
Of note is the LS XJ 2025 is the smallest LS size that came with the SSQA (skid steer quick attach). That played a big part of choosing that size because he wanted the flexibility of the SSQA. He will eventually have forks and possibly a grapple (Everything Attachments Wicked Root Grapple of course).
If you haven't found all the tractor video's on you tube its a great place to see the size tractors you looking for at work.
Other brands have the SSQA as well.
