Abstract. The complex physiological-hygienic evaluation of the working conditions of agricultural machine operators in the dynamics of the annual production cycle of growing crops is carried out. It is set that the machine operators performing basic types of work are subject to the combined effect of harmful factors of environment and labor process, the levels of which correspond by the degree of deviation from the hygienic standards to harmful labor conditions of 1-4 degrees (classes 3.1-3.4). Levels of blood pressure, hemodynamic and functional status (IFS) show tension of regulator systems and reducing of the body's adaptive capabilities of the machine operators that can be caused by exposure to adverse working conditions. Key words: agriculture machine operators, working conditions on the tractors and combine harvesters, functional disorders, tension of adaptation mechanisms.Tractor operators and machine operators (hereafter -agricultural operators) that work with agricultural equipment expose themselves to various professional health risks. They include higher levels of noise and vibration created by equipment operation, dust (organic and mineral), exhaust fumes, microclimatic discomfort in the cab, physical and emotional loads [1]. The impact of hazardous working conditions can lead to functional disorders and dysfunction of organs and systems of agricultural operators, malfunction of adaptive mechanisms, development of preclinical and pathological changes that advance profession-related and professional diseases [3].For this reason, determining the risk factors that decrease the body functional reserves will help develop and implement timely measures to maintain the health of agricultural operators which is the biggest professional group of agricultural employees.The purpose of the study is to assess the working conditions and their impact on the functional condition of the agricultural operators. __________________________  Novikova T.A., Raykin S.S., Buyanov E.S

Проведена комплексная физиолого-гигиеническая оценка условий труда механизаторов сельского хозяйства в динамике годового производственного цикла выращивания зерновых культур. Установлено, что механизаторы при выполнении основных видов работ подвержены комплексному воздействию вредных факторов производственной среды и трудового процесса, уровни которых соответствуют по степени отклонения от гигиенических нормативов вредным условиям труда 1-4-й степени (классы 3.1-3.4). Уровни артериального давления крови, показателей гемодинамики и функционального состояния (ИФИ) свидетельствуют о напряжении регуляторных систем и снижении адаптационных возможностей организма механизаторов, что может быть следствием воздействия неблагоприятных условий труда. Ключевые слова: механизаторы сельского хозяйства, условия труда на тракторах и зерноуборочных комбайнах, функциональные нарушения, напряжение механизмов адаптации.
