The article presents the results of a study of the soil compactor and the reasons that violate agrotechnical requirements. The task of studying compaction rollers is presented to evaluate design flaws and search for new technical solutions to optimize the operation of tools for soil compaction. A schematic diagram of a soil compacting roller is presented, consisting of evenly spaced disks mounted on an axis, along the circumference of which there are strips that crush and compact the soil. The results of experimental studies are presented and a multifactorial model of changes in soil density is obtained depending on a number of parameters of the compacting roller: the mass of the roller, the number of strips and the speed of movement of the unit. The optimal technical parameters for the press roller of a cultivator intended for pre-sowing tillage are given. The conclusions of experimental studies are presented, which reflect a mathematical model of changes in the density of the surface layer of soil after treatment with a compacting roller depending on a number of parameters, such as the mass of the roller, the speed of movement, the diameter of the disk and the number of stripes. The optimal weight of the roller is determined to be between 70 and 73 kg, the optimal speed of movement of the roller can be in the range from 9 to 10.8 km/h. The recommended number of strips is 8 pcs. Disc diameter range 0.31–0.34 m.
