Otto, you should be posting this in the machinery forum so more people will see it.

I used to dry corn for my neighbor a few years back. I quit doing that for lack of time to get my own fieldwork done.

Since then, they have put up new bins with fans and stir-ators. I know one of them is a Sukup and the other is a Westeel. Apparently it works quite well for them. And I'm sure that the moisture is at least 18 to 20% when it goes in. Perhaps even more. I can't say for price but the GSI systems have been the cheapest around here.
