I don't know how many a platform on a combine could take but a disc mower conditoner takes a lot of fawns in late May when Alfalfa fields are done and quite frankly the famer won't even know it happened until the vultures and crows show up right after cutting. It is sad, and no farmer I know who has had it happen enjoys it but it does happen... Have seen farmers run Quads infront of their windrowers trying to prevent it but those fawns just hunker down.. Hard to see when the hay is waist tall and you are cutting 16 feet at one time...
