I have about a 8 or 9 acre hay field with fescue, bermuda, and johnson grasses.  A neighbor hays it three or four times a year.  He takes all the hay for free.  He provides fertilizer and all the labor.  If he doesn't do the fourth cut, then, around the first freeze, I mow the parts closest to my yard and barns with my rotary cutter to keep the winter fire hazard to a minimum.  It's a win-win for both of us.  I don't need hay, and he keeps the field clean and it stays taxed as agri.  BTW, when I disturbed about a half acre building a quarter acre pond last year, I seeded it back at my expense.
