Yes these wagons are sort of narrow as they were all used for hauling grain and ear corn with sideboards earlier in their life. They have a pivot on the rear of the sills and were set up to be lifted with a tractor powered A frame hoist deal to dump into a drag elevator combo. I think there is a picture on a slide somewhere but I have not seen it for many years.  Also were made that way to fit 2 side by side in narrower driveways of older buildings. Alternating bales that way seemed to always tie them together very well. I never lost a load stacking them that way and they often got pushed up a fairly steep barn bank into the barn that way as well with no issues. I could usually get 120-125 on a wagon this way.

That was a good J&M elevator I bought used but have since sold it when I made some other changes. I think it was at least 40' and electric motor drive.

Was too cheap to buy new matched tires for wagons that only got used occasionally :-)  (use what you have on hand)
