NE SD | They move more than ya think though Bob. The bins I was talking about are 42' x 7 ring - about 33,000 bu. I'm sure with the smaller bin you could get away with a thinner pad towards the center by filling up towards the center but those 2' footings are nice for the sumps if nothing else. Digging holes in frozen ground doesn't work real well. They are poured to last at least this we know. Good damn concrete from the Hutterite colony. Grandpa put up 5 8500 bushel bins in the 70's. They were all poured with probably 10" footings and 6" pads. Today only one of them is still on the original concrete. It cracked right around the edges of the bins and they sunk, etc. One of them had a 2" or so crack right through the center of it so they must move more than you think. Rats had about 2 yards of gravel and corn in there under the air floor. Shoulda seen the mess. Every time the loader hit that pad 30+ rats ran out.
