Modeling of Tractor Seat with reduced risks of Whole-body Vibration

India is the largest manufacturer of tractors in the world. It is the largest world market for tractors below 37 kW, due to the small size of land holdings. The current population of tractors in India is around 1.5 million and more than 0.15 million tractors are added to Indian agriculture every year. They are being mainly used for primary and secondary tillage operations and as a means of transportation to haul goods, people and even animals. With the high degree of mechanization of farms along with increasing size and complexity of farm machinery, a safe comfortable working environment for the operator becomes an important consideration if productivity and customer satisfaction are to be enhanced. The occupational hazards of tractor driving include deafness and disorders of the spinal column and stomach, caused by vibration. It has been widely recognized for a number of decades, that whole-body vibration (WBV) is a major source of discomfort for agricultural vehicle operators during typical farm operations.
