The tractor is the major machine used in agriculture aspects for various purposes. The operator wants more comfort while operating in various situations. Generally, due to sudden shocks and vibrations, effects in various parts of an operator. A large number of studies have been conducted and researchers have suggested several criteria for evaluating discomfort and the suitability of a tractor seat in a given working condition. The studies have led to various parameters, viz. the body pressure distributed under and supporting both the buttocks, thighs, and the back of an operator, control of posture in static or dynamic condition, ride vibration, exposure time on task, and other factors. But in the absence of a more definitive and the most logical criteria particularly from the biomechanical viewpoint, the researchers will continue to design conditions and procedures to understand the seat dynamics and evaluate the seating discomfort. By introducing a sliding mechanism in a curved frame by using roller bearings the sudden shocks and vibrations are absorbed by this mechanism and it enhances the feeling of comfort, safety, convenience, and results in higher work output from the operator. Therefore, this paper reviews the research and development information available in this regard and attempts to set the most appropriate procedure for assessment of seating discomfort during tractor drivin
