I don't know if I would want to run 20 acres with a two wheel machine. Are you talking 20 acres in production or 20 acres with half or so in fallow? You should pick up the book "the New Organic Grower" by Eliot Coleman. Eliot claims he did it for years with only a walking tractor but now owns a compact loader tractor. He market gardens 10 acres or so in the Northeast (Vermont if I remember correctly) but has half of it in fallow at any time. Parts of the book won't apply to you since you're in Texas and shouldn't need greenhouses to the extent he does Even if you're not gonna be organic, it's a worthwhile read for anyone thinking about market gardening.
