All human occupants vibrate to some degree in any moving vehicle, whether it is a car, truck, train, aeroplane or boat. The reviews on the effect of vibration on human health have shown serious evidence of operator ill health that may be attributed to tractor drivers. The frequency range of 2-6 Hz has been observed to be the most harmful for the human operator because resonance occurs in this frequency range. Considerable effort has been made to establish the optimum design parameters for tractor seats. Further reductions in the level of ride vibrations experienced by tractor operators appear to be necessary and some possible methods of achieving significant improvements have been outlined. These methods have led to the evolution of several seat suspension systems and emphasise the use of the principles of ergonomics in the operator's seat design. In this paper, a review of the work done in this area, particularly with respect to tractor operators, is presented and discussed.
