A draft horse (US) or draught horse (UK), also known as dray horse, carthorse, work horse, or heavy horse, is a large horse bred to pull heavy loads and work agricultural tasks such as plowing. A number of breeds with varying characteristics are of this type, but all share common traits of strength, patience, and a docile temperament. While indispensable to generations of pre-industrial farmers, draft horses today are used for many purposes, such as driving, logging, and farming, as well as recreation and showing. Draft horses have been crossed with light riding breeds, such as the Thoroughbred, to create sport horse and warmblood breeds.
