The process of harvesting soybeans by direct harvesting is a very energy-consuming process. The application of the method of combing plants on the root will partially reduce energy consumption by reducing the working organs. It has been found out that modern combine harvesters do not provide the quality of harvesting in accordance with agrotechnical requirements. The results on the use of a combing harvester for harvesting soybeans by the method of combing plants on the vine are presented. With a minimum level of losses behind the harvester (7.9 %), optimal indicators of the technological process of harvesting soybeans by the method of combing were determined. Based on the data of the experiment, a regression equation has been obtained that adequately characterizes this process. An alternative version of the combing header is presented, which allows excluding the impact of the inertial component and leads to cracking of soybeans before they break off from the stem and fly forward along the course of the tractor with the combing header. In the future, it is possible to use a screw combing harvester for harvesting seed crops with a row spacing of 30 cm or more.
