Apologize for the long post. I'm going to use my recently purchased Gleaner G to do my grain harvest. I'm going to store it in my silo. I have a poured cement silo (20 X 70) and I plan on using it as my grain bin. Its been done before (actually in my silo but not by me) and I don't have much choice. My first year at growing my own grain and the silo is empty, in real good shape, has a roof and is dry. My grainery in my barn is a rat's paradise. I plan on laying a layer of black plastic on the bottom and then laying a 100 ft length of perforated plastic tile on top of the plastic to attach a grain aerator. I'll then blow my grain in using an Agri-vac from my dump wagon. Being this is my first year I only have enough grain to go up about 7 feet (almost laughable when you read the discussions on the super 7's capacity) By the way I checked with an engineer who warned me not to go above about 20 feet with dry grain because of the huge horizontal forces created by dry grain. Can anyone give me further advice or tell me if I'm doing something wrong. My hope is to use some for my own feed and sell the rest at the best time (can't in my parts sell it out of the field). Thanks for any help.
