ABSTRACT
The combine harvester is a complex system, and human interaction with it becomes complex to the same extent. While operating the combine, the operator may face numerous health hazards, including noise, whole-body vibrations, temperature extremes, dust, bright lights, diesel exhaust, and awkward postures due to placement and operation of the controls and monitor, as well as psychosocial health risks, such as time pressure, extended working time, and irregular shift work. During harvesting periods, it is quite common to operate a combine for 16 h/day. Furthermore, several operators may alternately operate the combine.
