I don't recall if you have irrigated hay ground but if you get one cut a year just do a share crop deal. If it is irrigated and you get 3 cuts it makes a little sense but is marginal. It takes a lot of hay at $75 a ton to pay for a tractor, baler, swather, maintenance, and fuel. 3 cuts might do it, 1 cut won't. There is, of course, more to it and sometimes it is just nice to do your own thing. If you do buy a tractor by a used one of at least 50 hp and 85 would be better.
