The combine harvester is a key unit in the crop production mechanization system, determining the efficiency and timing of harvesting operations. Proper equipment selection, an understanding of the operating principles of threshing and separating devices, and adherence to technological settings are essential not only for harvesting speed but also for grain quality, its market value, and the minimization of threshing losses. For an agronomist, knowledge of machinery design, whether it is the classic "Don 1500," the high-performance axial-rotor TORUM 740, or specialized forage harvesters, is a mandatory condition for ensuring the efficient functioning of the entire agricultural enterprise.
This collection gathers materials covering both the fundamental principles of threshing and separation, and the specifics of operating particular models of domestic and foreign machinery. Readers will find articles dedicated to the influence of combine design parameters on performance quality, principles of efficient organization of the harvesting process, and the integration of technical resources into the farm's overall logistics system. In addition, there are reviews of harvesting technologies for various crops—from grains and forage crops to grapes—as well as methods for increasing the efficiency of field operations, including desiccation techniques that facilitate mechanized harvesting.
