30 inch spacing, the 12 row planter thing doesnt make a whole lot of scense because that thing can hold a 12 row, the narrow gaps thing doesnt fit because he basically farms everything in sight of the grain elevator, and its pretty much wide open, and it i doubt its a money issue, because the guy runs two new peterbilts, and a brand new 1000 bushel brent cart, and a new 305 magnum case ih, so it is really not making a whole lot of scense.
