Horse-drawn vehicle Horse-drawn vehicle A horse-drawn vehicle is a mechanized piece of equipment pulled by one horse or by a team of horses. These vehicles typically had two or four wheels and were used to carry passengers and/or a load. They were once common worldwide, but they have mostly been replaced by automobiles and other forms of self-propelled transport. A two-wheeled horse-drawn vehicle is a cart (see various types below, both for carrying people and for goods). Four-wheeled vehicles have many names – one for heavy loads is most commonly called a wagon. Very light carts and wagons can also be pulled
Horse-drawn vehicle by a pair (or by a team of several pairs) have a "pole" which attaches between the wheel pair. Other arrangements are also possible, for example, three or more abreast (a "troika"), a wheel pair with a single lead animal (a "unicorn"), or a wheel pair with three lead animals abreast (a "pickaxe"). Very heavy loads sometimes had an additional team behind to slow the vehicle down steep hills. Sometimes at a steep hill with frequent traffic, such a team would be hired to passing wagons to help them up or down the hill. Horse-drawn carriages have been in use
