I have an old combine bin on wheels and I am going to try again this year to have it filled out in the field from the combine. Last year I got some from a friend of mine and the trailer holds about 2500# and when I went to pay him he actually wouldn't take anything for it. Bet I won't find that kind of deal this year. I think the price to the farmer is about $5 per bushel. If I could pay that It wouldn't be too bad.
