Abstract: The indicators of the feed output and, in general, the profitability of animal husbandry rely on the effectiveness of forage harvesters. Models depicting the performance and fuel use of forage harvesters were received resulting from the analysis of the fuctioning indicators. An effectiveness ratio was suggested for a comparative analysis of their effectiveness. It considers the relationship between performance and fuel use while harvesting grasses of different yields. Three forage harvesters: Jaguar-840, Jaguar-690 and Maral-125 are analyzed in this article when selecting grass windrows dried to a moisture content of 65%. Comparative analysis of the concerned forage harvesters revealed that the fullest loading of the Jaguar-840 and Jaguar-690 harvesters is achieved with a yield of grass more than 17.5 t/ha, and the Maral-125 combine harvester-with a yield of grass more than 10 t / ha. If the grass yield is up to 7 t / ha, the fuel rate of the harvesters is almost the same. Its changes occurs along a decreasing exponential curve with an increase in the yield of grass. The highest effectiveness ratio, equal to 33.54 (ha / shift)×(t / l), during silage preparation, has a Jaguar-840 forage harvester with a grass yield of 10.0-20.0 t / ha. The lowest effectiveness ratio is 5.63 (ha / shift)×(t / l), has Maral-125 harvester in the grass cutting with a yield of 25.0-30.0 t / ha.
