The main direction of technical progress in agriculture, including in field cultivation, is to increase the energy saturation of all types and classes of tractors, which makes it possible to carry out work using wide-cutting units at higher speeds with fewer workers and shorter work periods. Therefore, the hygienic problem of changing the conditions and nature of work is becoming especially relevant.
The purpose of this study is to study the conditions and nature of work on modern tractors and agricultural machines operating at high speeds - MTZ 80/82, T-150K, etc.
The work uses well-known hygienic and physiological research methods to study working conditions and the state of human performance. For a more in-depth study of the functional state of the neuromuscular apparatus during labor, the method of electromyography was used. The electromyogram (EMG) was recorded on a single-channel "Malysh" electrocardiograph while maintaining the standard load.
Dszcybkjcm, xnj an increase in energy saturation and an increase in tractor speeds lead to an increase in the frequency of control movements, an increase in the tension of the physiological functions of the machine operator's body.
