USA HISTORY

Detailed explanation-1: -Oxen were chosen over horses to pull the wagons because of their strength, and because they were noted for being easier to work. They were generally docile, gentle, easily guided by a child, and strong enough to lug heavy wagons over rough terrain.

Detailed explanation-2: -Oxen were both more pliable and durable than horses or mules. It was easier to sustain oxen on the trail as they were more content to forage on the grasses of the Great Plains, whereas horses and mules required grains (such as oats) for optimum performance, an expensive and heavy substance to haul along the way.

Detailed explanation-3: -Oxen were most often used for pulling this type of wagon. It required two yoke (pairs) of oxen. A spare yoke often trailed behind so that the livestock could be rotated and rested. For those who preferred mules, an equivalent number of harnessed mules could have been used in place of oxen.

Detailed explanation-4: -Converted farm wagons, called Prairie Schooners, were actually used and pulled generally not by horses, but by oxen. In fact, oxen were led. There were no reins. Plus, the Prairie Schooner wagons often had no seat and the pioneers generally walked along the Trail.
