A three-degrees of freedom (DOF) analytical model for a tractor seat suspension is presented in this paper. The response characteristics of the model have been determined using a computer simulation technique. It was observed that vibration transmissibility predicted by this model matched very well with the measured values. In contrast, the values predicted by 1-DOF or 2-DOF did not match that well. The suspension system having spring constant between 10.726 and 18.957 kN/m and damping co-efficient 0.665 and 1.099 kNs/m were found to be suitable for Indian tractor seats. Furthermore, the model could be employed as a tool in selection of optimal suspension parameters for any type of vehicles.
