. That is what I said a Horse does not pull a load. A horse that is in a harness pushes a load with his or her shoulders with a collar which is over their shoulders, which is connected to two large straps of long leather which is connected to the load. The horse then moves forward and pushes the load with their shoulders by pushing against the collar. If you ever go to the state fairs that have horse pulls, just remember it is really a Horse Pull. The only real way a horse can pull a load is if you tie it to their tail and they walk forward. Or the horse could use it's teeth to pull on something small and light weight. A horse pushes a wagon, a plow, a sled, a log, etc. An ox does the same thing, it pushes a load with it's shoulders. Horses and Ox do not pull loads they push a loads. . .
