I am looking for something that I can do using my quarterhorse on my farm. He used to be a ranch horse. I want to ride him more and figured if I could find some sort of "chores" for us to do it would be fun for both of us. Can he help me to move fence posts across the property (not pull them out) just move them to where I want to plant my grapes? If so, where do I tie them? To the saddle horn? I have not technically driven him, I have walked behind him with long reins. Any suggestions would be appreciated.
