On the compliance of the productivity of domestic combine harvesters and the yield of grain and leguminous crops in Russia

The industry of growing grain and leguminous crops is not supported by the production of domestic combine harvesters capable of ensuring the organisation of harvesting operations with a high level of efficiency in the whole range of yields typical for Russian conditions. The analysis of the main characteristics of modern “Rostselmash” combine harvesters in relation to the yield of grain and leguminous crops has revealed the need to improve the range of combine harvesters produced in the Russian Federation. The calculation and graphic method has shown that in the line of domestic combine harvesters there are no models designed for harvesting grain and leguminous crops with yields up to 1.7 tons/ha and from 2.9 to 3.5 tons/ha. The absence of these models leads to higher production costs of cereals in farms, for which this yield is typical. It has been established that harvesting grain and leguminous crops of different yields requires a range of 5 models of combine harvesters. Each of them will have 100% use and maximum efficiency of utilization in the yield range, for which it is designed. The range of models, built according to the proposed principle, will provide the need of any farm in combines for harvesting grain and leguminous crops with yields from 0.87 to 10 tons per hectare. The graphical analysis method facilitates the selection of a rational combine harvester model suitable for local conditions by the criterion of maximum loading of the threshing and separating device.
