Very interesting unloader. How many pounds per minute? That looks very fast for a silo unloader.
We use drive over piles. 5% to 6% shrink year after year.
That silo makes a lot of sense on your farm. Very simple. 2 people can fill and easy to unload. Very nice!
From what I have read, the average bunker silo has 10-15% shrink and the average top unload tower silo has around 7% shrink. But with both types of silos, you can manage to get it better than that. For me, I would rather manage a tower silo. A bunker silo looks like a lot more work to manage to have good feed quality, and wouldn't really fit with our farm anyway. I expect we will put a Valmetal Autoration system in someday, and that would work great with silos. But we only milk 120 cows. Once a farm is milking several thousand cows, I doubt there is anyway tower silos would be real practical. In the end, each farm has to decide which method fits his operation best.
