Due to the agricultural modernization, some crops already have their production process fully realized by farm machinery. In order to enhance operational performance and reduce both fatigue and accident risk, it is fundamental to provide a safe and adequate working environment. Therefore, the working station must be adapted to the operator’s anthropometric and mechanical characteristics. The present study aimed to... Read more.
