Studies conducted by anthropometric and ergonomic assessments contribute to aid for new projects based on the design of machines and equipment. The objective of the present work was to perform an anthropometric analysis of workers who operate forest harvest machines and an ergonomic assessment of the operator cabin of a Feller-Buncher, in order to gather information needed for future modifications. Analyses were performed at CENIBRA forestry company in Minas Gerais. The anthropometric evaluation of the operators was conducted by two sets of measures, while standing and sitting. During the ergonomic assessments and measurement of controls positioning and field of view, distances were determined from the seat reference point (ARP) in three dimensions (x, y and z). The results showed that there is need for ergonomic improvements in the seat, controls, control panel, symbology commands, dials and warning lights.
