Na podstawie badań własnych i literatury omówiono zużycie energii w kombajnach zbożowych, które uzależnione jest od konstrukcji zespołów roboczych tych maszyn, jak również od właściwości młóconej masy zbożowej.

On the basis of own studies and literature review the authors analysed energy consumption by combine harvesters. Considerable excess power in recent combine harvesters equipped with 80-250 kW engines enables normal operation even under extremally difficult conditions (instantaneous overloads). Moreover, at surplus power some additional technological and control facilities may be easy installed on the combines. The highest proportion of power (above 40%) is consumed by power transmission and drive, especially when hydraulic systems are applied. Also multi-drum and axial-flow threshing-cleaning assemblies of the combines are characterized by high energy consumption. About 30% of total energy is consumed by conventional threshing-cleaning assembly, while in axial - flow combine harvesters even by 20% more.
