The draft horse is a generic term used to describe the heavy working horse that has provided transport and 'energy' for mankind in the days before the engine was invented and up to the current day. The best known breeds are the Shire, Clysdesdale, Percheron and the Suffolk. They can still be seen today, working on small farms, logging, and pulling brewery delivery wagons in suitable areas. For many years, they were also used for milk deliveries - being far more economical to run in areas where a lot of stopping and starting was needed than the petrol engine.
