A Critical Review of Seating Discomfort and Anthropometric Consideration for Tractors

Abstract

The seats that are available in the tractors are not as sophisticated as in the cars and most of the tractor operators feels discomfort while operating the tractor. This review not only makes the tractor seat sophisticated one but also includes all other design considerations. It is necessary to design a seat by considering various factors like dimensions, cushioning, anthropometry etc. Anthropometric consideration is not a mere assumption here. In the view of anthropometry, a survey form was created to analyse various pain levels of a tractor operators. The survey was taken from different age and different experience tractor operators to obtain more relevant data for the analysis. At the end of analysis, the dimensions were varied according to the analysis and also consider the ISO and BIS recommendations. To give more comfort to the tractor operators some additional features like hand rest, air cushioning for the seat were added and these also reduce the tractor operator’s pain.
