The paper aimed to analyze the mechanization of grain maize harvesting using self propelled combines. The John Deere combine of the W series are highly powered, easy to maintain, effective from the point of view of fuel consumption, and available for a wide range of crops and working conditions. The main technical and functional features of John Deere combines of the W series are: Quick cutting, low height sowing platform. Working width between 4.3-10.7 m. Thresher equipped with a beater with 10 beating rails (Ø = 650 mm) ensuring full threshing and low grain breaking percentage. The shaker has a large separation area conferring full recovery of kernels and grains from the straws. The separation system is fed by helix converters avoiding the gliding of matter when harvesting on slope lands. Maize harvesting needs a large amount of labour and it needs to be done in the shortest time, particularly on the plots on which we cultivate winter cereals. There are three phases of ripening in the process of formation and maturation: Milk ripening; Yellow ripening; Full ripening with below 30% moisture. The calculus and making up of grain maize harvesting aggregates led to the conclusion that to ensure maximum working capacity and minimum fuel consumption, the combines must be ensured with the proper means of transport of the crop. The number of transportation should be correlated with hourly productivity and crop transport distances.
