Winter wheat is one of the widespread crops in Ukraine. The search for methods to increase the yield and consumer properties of wheat, with-out compromising environmental safety, is one of the important scien-tific problems. The principles of precision agriculture point to the proper positioning of the seeds, recommending the method of "upward germination" (positioning the wheat germ vertically). The main objec-tive of this study was to develop a new geometric model of wheat grain with a displaced centre of mass, as well as to conduct the theoretical research and numerical experiments on the orientation of grains using their multiple impact interaction with inclined surfaces. A new model of germ consisting of two different end semispheres and amid-line trun-cated cone was proposed, with a displaced centre of mass. Taking into account the physical properties of the objects, the concept of arrange-ment of gravity orientation of seeds in a stream was applied. This con-cept was based on various ratios of kinetic parameters of bodies with a displaced centre of gravity following an impact. The results showed that the orientation process can be controlled by changing the inclina-tion angles and the length of the walls of the tray orientator within the working velocity range. This must be done before impact interaction of 0.2-0.3 m s-1 when the inclination angles of the impact interaction planes are 24-32°C
