An ox is any cow that is trained to do work. They are most often steers, but bulls and cows can also be trained. A critical features is that the animal has horns. This is because when they are yoked, and going down hill, the yoke will slip over the head of the ox as the wagon has a tendency to go faster than the ox downhill. We visited the ox ride with Elizabeth (Sheri's sister) and their family. Her granddaughter was funny as she would say go and wanted the ox to go around again.
