[Ergonomic characteristics of the work sites of grain harvesting combines]

The organization of places of work at grain harvesters CK-5, CK-6 and CKD-5, widely used now in agriculture, has a number of significant ergonomic shortcomings, i.e., a large size of cabs, excessive height, depth and inadequate control of the work seat, arrangement of control mechanisms beyond the reach of operators, insufficient visibility, exceeding permissible levels resisting force of control mechanisms. The greatest physical load is experienced by the operators, whose workplaces do not correspond to their anthropometric characteristics. These operators also undergo the most distinct changes of the functional state of the central nervous, cardiovascular and neuromuscular systems.
