I’m with Andy, loose hay is the answer, as long as you are not planning on selling hay.  if you have a good way to get it off the wagon it is the best feed and in my opinion less labor/capital intensive than small squares.  That said, we just acquired a teamster 2000 that I would like to run a 9′ sickle with, but we will still put it up loose.  I have tried to post a picture of out set up, we use three to pull this and then use a grapple in the barn to unload, very slick.  Sorry if this is a little off subject.  My good friend Tim is driving and I am stacking.
