Research on Human Engineering in Tractor

Abstract

The human engineering research efforts on the driver's seat and controls were concentrated on investigation of the problems involved in them and on anthropometry for the farmers.
From our study on the dimensional adaptabilities and handling properties of 90 tractors, some improprieties were found in the range of seat adjustabilities, seat surface height, location of foot control pedals and direction for applying pedal thrust.
Twenty-seven anthropometric iteme were measured for 153 farmers. As compared with other data, the data thus obtained were closely similar to those of anthropometry of Japanese pilot. This similarity might be owing to the age distribution of our subjects, which concentrated in 18-22 years old.
The results of the study on the driver's seat and controls with respect to human engineering based on anthropometric data are as Fig. 10.
