Hello Mr.agco

Drive-over pile. Most of it is done that way around here. Dairy men can afford the uprights & a few have concrete bunkers, but most is on the ground or a crushed limestone pad. If you get it at 65% & your packer tractor never stops moving it will turn out good. Cover & seal as soon as possible. Someone mentioned about sizing the pile to the size of the plastic cover, but don't forget about your feed-out rate. Size your plastic cover to the size of your pile.
