This paper presents a mathematical modelling in 3D space of the scatterers of seeding opener of the grain-fertilizer seeder using the matrix method. The investigated model is presented as a mechanical system with eight degrees of freedom. Based on the results of simulation, the trajectories of the points on the oscillating scatterer in the form of a pendulum hemisphere and their projections on the XOZ and XOY coordinate planes as well as the linear velocity components of the considered points and the angular velocities components of the investigated scatterer are derived. The obtained data allow us to state that the use of the oscillating scatterer-pendulum hemisphere will improve the quality of sowing in terms of the flight range, spread and distribution of seeds, consequently, it will increase in the yield of crops. The results will also be used in further studies of mechanical system dynamics of the investigated seeding opener with scatterer of the grain-fertilizer seeders.
