"Animal drawn carts, especially bullock carts, are the oldest mode of transportation, existing in India and in few other countries since the past unknown. About 15 million bullock carts exist in India. Statistic shows that number of bullock carts has not reduced in last 30 years, belying the popular concept that bullock carts will disappear with the development of society. Reasons are many. The fact is that still in India, bullock carts are the most important mode of transportation in many parts of rural India. Unfortunately, the technology of the carts has not been improved. The conventional bullock carts are made of wooden wheels and bamboo/wooden load carrier (known as platform). More than 80% bullock carts are of conventional type. Only a few number of carts has been partially converted to metallic (which can not be termed as ‘improved’). As this mode of transportation will exist in India, there is need for the improvement of the technology."
