This is an Antique 12 spoke Hay Wagon. You will notice that the front wheel and rear wheels are the same size. My understanding is that this helped keep a properly loaded wagon from tipping as the horses pulled it from the fields. Of course my thought as I read this was that would also depend on the experience of the driver!
