The analysis is based on data that were timed during the operation and repair of diesel engines of agricultural machines and, in particular, engineering monitoring about the most frequent characteristic failures of parts and elements of power energy institutions, as well as about possible causes of the course and development of typical inequalities. The typical causes of failures of elements of diesel power plants, which can be different, have been determined. First, the specific design features of a particular type of engine, which may be uncharacteristic for other typical diesel engines and must be eliminated by appropriate changes to the diesel engine design. Second, improper operation of the diesel engine, such as misapplication, inadequacy of grade fuel and oil refueling design failure. Thirdly, sudden failures for the use in the manufacture of a diesel engine of some materials, defective parts, as well as significant violations of installation and adjustment technologies. In order to prevent failures, choosing the above reasons, it is necessary to correct design flaws, improve technical control, follow the operating instructions, as well as carry out organizational diagnostic measures. In this article, attention is paid to malfunctions and defects, the development of which is caused by natural processes of equipment degradation under load, ensuring the working processes of the diesel engine and its systems, as well as additional accelerating factors, such as contamination of the coolant, oil, fuel, an increase in backlash and clearances, enough values for long-term operation of diesel power plants of agricultural machines of various types.

Based on the analysis of most domestic combines, it is established that they have a traditional scheme of threshing and separating device, which includes one or two sequentially arranged threshing threshers and keyboard straw shaker. The design of drumming from rods with cross plates provides, first of all, intensification of process of threshed grain. Cereals are threshed easily, so there is no need to intensify threshing. For example, when harvesting grain harvester KZS-9M "Slavutich" with a gap at the outlet between the threshing drum and the drum 18 mm and the speed of the threshing drum 450 min-1, the loss of threshing was absent in all experiments. In this case, the transverse plates of the drum are an obstacle to the movement of the threshed mass in the threshing-separating device, forming a dead space behind each bar, where a small component of plant mass accumulates. The quality of the threshing and separating device of the combine harvester was determined by the coefficients of undersmilling, separation, crushing and clogging of the grain received for cleaning. Damage to the grain during threshing in the thresher is mainly due to the influence of the circumferential linear velocity of the threshing drum and the gap between the threshing drum and the drum. Therefore, the gap in the threshing space is variable and changes in the direction of decrease from the entrance of the plant mass into the threshing device to its exit. To summarize, we used the gap in the threshing space at the outlet of the thresher. In this regard, the beginning of the tests was at a drum speed of 450 min-1. During the tests it was found that the greatest influence on the damage to the grain has a circular linear speed of the threshing drum. Thus, when increasing the speed of the drum per 100 min-1 from 450 to 550 min-1, the damage increased from 1.5% to 5.5%, ie almost 4 times.

The article presents the results of theoretical research on the methodological provisions of the weight of the criteria in determining the technical level of agricultural machinery. The expediency of using relative, in parts of change, values of evaluation indicators, which allows to objectively and reliably obtain the value of the weight of the criteria in determining the technical level of agricultural machinery. The applied problem of determining the weights of the criteria in the study of the technical level of combine harvesters is considered. Five criteria are substantiated: reduction of direct costs, reduction of energy consumption, reduction of labour costs, reduction of material consumption, increase of reliability. The weight of the criterion reflects the degree of its importance in the rank of the sequence, their values are in the range 0…1. Five indicators are substantiated: operating costs, direct fuel costs, specific labour costs, specific material consumption, failure time. It is established that in the process of operation of the combine harvester Slavutich KZC-9M with a reduction of 30% of operating costs, the weight in determining the technical level is 0.1473. Studies have shown that a 25% reduction in direct fuel consumption is 0.1228 weight in determining the technical level of the combine harvesters.
