In short. No. A thoroughbred cannot accomplish the same things that a draft horse could. Similar things, but not the same. Can it pull a cart? Yes, a lighter one. Could it plow a field? Yes, with smaller, lighter equipment. 2 of my horses are trained to drive (well, 3 year old is in training) and I would never expect them to do draft horse work. That doesn't mean that with a proper collar they can't drag the arena or pasture though, as I often have them do.Is the average thorough bred horse strong enough to be used the same way a draft horse is ment to be used? Pulling carts, plowing fields? That kinda stuff.
