Abstract

The market for self-propelled combine harvesters in Russia is diverse, with all major global manufacturers present. The domestic leader in combine building is the Rostselmash combine plant. The line of the plant is represented by 24 types of agricultural machinery, and it is constantly being updated. One of the new models “NOVA” is designed for direct combining and separate harvesting of grain and other crops. Self-propelled combine harvester “NOVA” is designed for direct combining and separate harvesting of grain crops and other crops, and with the use of accessories supplied by a separate order of the consumer, for harvesting the grain part of corn, sunflower, grain legumes, cereals, rapeseed, on flat fields with a slope of no more than 8 degrees in all grain-sowing zones. The article presents an analysis and assessment of the main technical and operational and working technological indicators of this combine harvester, based on the protocols of the MIS of the 2016–2017 seasons, for three crops: winter wheat, spring rape and soybeans. According to the test results, the grain harvester “NOVA” showed high technological productivity and reliability, and the operational time availability factor was 0.995, the MTBF of the second complexity group was 125 g. The technological process of the tested combine corresponds to the coefficient 1. Based on the results of field tests, summary tables and the results are verified with regulatory documents, in such indicators as: productivity per hour, utilization rate of shift time, and specific fuel consumption during shift work (without loss of power). With the full satisfaction of the “NOVA” combine harvester with all official requirements, its indicators for grain loss behind the header, total grain losses behind the thresher, and grain crushing decreased even in comparison with those declared by the manufacturer.
