      <subfield code="a">An experimental set up frabricated to measure the pressure distribution on the seat pan and back-rest of a tractor seat. Results indicate that all the parameters, namely seat pan, back-rest profile curvatures and the back-rest angle of inclination, affect the pressure distribution. It is concluded that a seat pan with radius of curvature 75 cm, back- rest with radius of curvature 30 cm and back-rest seat inclination 10 º are most suitable parameters for Indian tractors operators</subfield>
