The ranch saddle is built to give it's rider comfort with long hours of riding. The entire saddle must also be built strong and durable as a working cowboy may ride that same saddle roping and working day after day - in all kinds of conditions.
Generally a deeper, well shaped seat is preferred as well as a plate rigging system. The plate rigging delivers a more even pull throughout the tree to give the horse more comfort. Most cowboys want the fork or swells of the saddle to sit low on the horse with a horn that is bigger in diameter for ranch style roping.
