This is a 2 wheel training cart. It works great for starting young horses. It need a seat. everything is in place. I have trained many horses to drive with this cart. You can go anywhere with it.The shaves can be broken down to fit in a trailer or you can have other shave ends made and attached to fit the size of your horse. Very simple process. It also has a brand new trailer wheel with crank to keep it up right when not in use or for rolling up behind your horse to attach the harness.
