The article presents the results of field tests of agricultural machinery in the operation of soil processing, sowing and harvesting in soybean cultivation. As a result of conducted studies, the design and operating parameters of a rotary plow were established, which ensure high-quality performance of main soil treatment with combination of organic mass sealing and soil deepening operations: the diameter of the spherical disk is 0.66 m, the distance between the rotor disks is 0.23 m, the width of the soil deepener stand – 0.16 m, the rotor attack angle – 24°, the rotor processing depth – up to 0.15 m, the soil deepening depth processing – up to 0.25 m; the width of the working machine is 2.4 m, the rotor rotation frequency is 385 rpm, the working speed is 2.44-3.00 m·s-1. The rotary plow with the specified structural and mode parameters provides a uniform depth of processing and complete cutting of stubble with 73-75% organic mass embedment in qualitatively processed soil, which corresponds to agrotechnical requirements for the technology of biological agriculture. The properties of the foot opener to create a compacted seed bed and help draw up soil moisture, as well as the use of the dew-forming effect, contributed to the increase in soybean productivity. The optimal width of the rows when sowing with a paw coulter for soybean plants is 60 cm, the reliable yield increase compared to the control was 86.2%. During the development of the combing device and the model of the interaction process of the soybean stalk with the combing combs, the angular zone of combing is set at 1.25π and the total stroke of the working machine for combing one stalk is equal to five distances between adjacent soybean plants in a row. At a working speed of the machine 7-9 km·h-1, the estimated drum speed range is 300-375 rpm for 8 brushing combs.
