The efficiency of the machines depends on the completeness of the scope of the indicators and the factors with which they are linked.
In choosing the best solutions, it is necessary to evaluate the system metrics, and the optimal option machine or set of machines to be chosen using optimization criteria.
The indicators for the quality assessment of mechanized works should be divided into common types for all mechanized works and for separate groups of technological processes: soil treatment, sowing and planting, plant care, harvesting of crops.
The system of indicators for the evaluation of agricultural machinery is expressed and evaluated with a large number of properties, indicators and characteristics of quality and reliability.
In general, quality has four groups of properties: feasibility, social, bio-ecological and reliability.
