| In this research suitability of dimension and size, location of some control equipment’s and driver surroundings with dimension, sizes and abilities of tractor drivers in Fars province was evaluated. Anthropometric data was essential requirement for adjustment of machine equipments with potentiality and competence of human. In this project the first necessary anthropometric data, for about 250 tractor drivers that were in age range of 20–60 year was measured randomly. The next some of prevalent tractors specifications in Fars province with anthropometric data of fifth and ninety and fifth percentiles of drivers was compared and evaluated. The results showed that stair space of evaluated tractors from the ground was more than optimum range. Chair depth of New Holland and Valtra tractors for fifth percentile drivers was great and for elimination of this difficulty proper seat back with adjustable thickness was recommended. The surveys showed that chair depth of model 285 and 399 of massey furgousen tractors was shorter than thigh length of ninety and fifth percentile drivers, which caused the driver’s discomfort. In massey furgousen tractor model 285 and Valtra tractors distance of steering wheel from seat reference point was more than hand length of fifth percentile drivers. Therefore the length of drivers hand was considered to be short for proper grip on steering wheel. The surveys showed that the drivers of massey furgousen tractors (Model 399) faced difficulty in for accessing the gear lever. | ||
