The goal of the investigation was to analyze parameters and indicators of modern combine harvester performance in grain harvesting, as a basis for reviewing the possibility for improved performance, capacity, as well as decrease of fuel consumption per product unite. Relevant parameters and indicators were calculated based on test results. The results achieved in maize harvesting were: fuel consumption was 14 l/ha, and 58.9 l/ha for efficiency of 24.2 ha/h and average working speed 8 km/h. Based on investigations in wheat harvesting, values of relevant parameters and indicators of fuel consumption were up to 13.6 l/ha, i.e. 38.1 l/ha for performance of 2.8 ha/h and 5.5. km/h average speed. The efficiency range of harvesters was 70%, with a considerable potential for improvement through better harmonizing of the working regime and the working conditions.
