how much horsepower does a horse have?

best answer
In fact over a short period of time a horse can exert up to 14.9 horsepower! The power one horse can produce is affected by that horse’s physical fitness and breed. Breeds like Thoroughbreds and Quarter horses can often produce more horsepower because they are bred and trained to work. Large draft horses that have lots of muscle can also produce a significant amount of power. Smaller horses like Arabians and ponies produce less power.
