Competitions
A starting load of 1500 pounds is set into the dynamometer, a weight that most teams are expected to be able to pull. Each team entered in the competition is hitched to the machine and they would pull it for a short distance. If the team can not pull the weight, they are removed from the competition and those that successfully pulled the weight continue on to the next round. The competition continues on in this way until only one team of horses remains.
