Here's two from last year I think it was, of my neighbor and his two Belgium's. He keeps the the Belgium's as pets, but there broke to harness as is evident. I know the photos where take in the fall, in the process of planting winter pasture (Arizona).
Dad went in with the tractor and disk, as well as the seed broadcaster, and disked it under once first.
Then the neighbor asked if it would hurt to disc the seed in a little more with the horses and the horse drawn disk, and Dad said sure, and took the pictures, which have since been displayed at the local feed store.
