Horse leading is an art preserved and taught at the Haras National du Pin in the Orne department. The connection and cohesion between the cart, the horse, and the hand of man are made through the harness leathers designed almost identically whatever their use. Stored in the work saddleries of the stud farm, their function is to allow the leading of the crew, the carrying of stretchers as well as the towing and reversing of the cart.
