The existing standard technologies for obtaining seeds of various reproductions in farms have a wide variation in the initial harvesting parameters, mechanization and technological modes of operation, which affects the final quality indices of seed material and its cost price. Modernization of the working parts of machines and units that provide the technology of loading and reloading operations will improve the quality of grain at this stage of harvesting. The installation of a new type of transporting device in a typical grain-handling machine loader allows to reduce the crushing and damage of grain by more than 20%.

This article highlights the functional aspect of developed software for statistical control of production quality and the possible areas of application of the developed software, in particular, manufacture of agricultural machinery at enterprises.

It was showed the results of the determination the optimal parameters of the narrowing partitions installed in pneumatic channels with a vertical up air flow for cleaning seeds. The installation narrowing partitions in pneumatic channels makes it possible to increase the productivity and efficiency for cleaning seeds from difficult–to–remove impurities by no less than 20%, while the optimal ratio of the width of the partitions and the depth of the pneumatic canal sections varies from 0.3 to 0.5.
