Somewhere among the family photo's, not sure who has them, but there are pics in the days before we had Balers and the hay was just loose and loaded onto carts loose. It was in the Fathers day growing up, his parents, old flat wagon being pulled by the draft horses, loaded up to the hilt coming up the driveway.
My Father used to have around 4 draft horses which pulled an old army wagon that he had. I don't recall seeing the horses linked up, it was either before I was born or very young. But we often used to play on the wagon, which was in the paddock.
