The first finds of a draft animal came from the time well before the birth of Christ and surely there have also always been different versions. However, the dishes were really innovative and elaborated only in the Middle Ages.
The first forms of the cummet were already in the early Middle Ages. It was only in the High Middle Ages, around 1000, that human beings continued to work out the oval dishes for draft animals. For many people in the Middle Ages, agriculture was the livelihood. Good draft animals were expensive and important. Only with the animals could a good harvest be brought from the field.
Before the time of the Kummets, farmers often used simple leather straps. These scourged on the skin of the animals, which often made them sore and could not work daily in the field. Due to the improved and mature shape of the cummet, the tensile load distributed evenly on the shoulder part of the animal.
The animals were made of wood, straw and linen. Thus, farmers earned higher yields in a shorter time. The expensive and noble leather cramp was reserved for the horses of the rich. This type of cummet is still used today.
The ox was not completely displaced, but was replaced in most fields by the horse whose performance was 50% higher than that of the ox. The customary fitting of horses with horseshoes from the 9th / 10th century also contributed to a considerable acceleration in agricultural labor.
