The article describes the efficient copying crop lifter of a combine header, which allows to significantly reduce grain losses during harvesting lodged crops. The article deals with mounting, adjustment of the proposed copying crop lifter and a method of experimental research to substantiate the optimal design and operating parameters of this device. The results of field experiment based on the method of a multifactorial experiment proved that the smallest grain losses are provided at the combine speed υ = 1.5 … 1.9 m/s, the thickness of the retainer plate h = 2.8 … 3.1 mm and the length base of the copying crop lifter l = 405 … 450 mm.
