Efficiency of using resource-saving technologies for harvesting grain (head) crops on the example of Georgia

Abstract

The article presents the results of the operational, technical, and economic research on traditional and two different resource-saving technologies for harvesting grain crops: grain harvesting was carried out using a standard Deutz-Fahr C6205 combine, and the same Deutz-Fahr C6205 combine, which was equipped with a special high-cutting comb-type reaper. Studies have shown that compared to traditional grain harvesting technologies, the use of resource-saving technologies reduces operating costs by 1.26...1.57 USD / t, adjusted by 2...2.4 USD / t; Increases combine harvester productivity by 70–80%, reduces harvesting time by 1.7–1.8 times, and significantly reduces technological and grain self-seeding losses.
