Hello all, I am a dressage enthusiast who has just acquired my first two minis. I am thinking I would like to teach them to drive. My only previous driving experience is ground driving. I have no idea where to start when it comes to purchasing driving equipment. How do I choose a cart and what type of harness/collar set up is best? How much can a mini pull? Currently I am focusing on ground work. These little guys are merely halter broken, they really know nothing. So I have time to find the right equipment. Thanks everyone!
