I understand that, and indeed that is why we decided against a silo, but if I had outlying land that I had to move a loader to, it makes more sense. The other factor that appealed to me was that it could not be used for anything else. Sheds here always end up full of cattle!I've got nothing against silos but it would limit its uses when empty and we already have a loader that I would never want to be without!
I think they are a good option if you need additional storage to complement an existing shed with elevators.
