!0 acres. All you need for that is a CUT (Compact Utility Tractor) Kubota makes a bunch.I missed two (with some lucky guesses).
I grew up in farm country in north Georgia. My family never owned the land so I moved on. My largest holding of land since then was 1/3 of an acre.
My dream one day is to get 10 acres so I'll have an excuse to buy a nice tractor.
