Mathematical model of sowing and planting machine

The article considers dynamic models of the sowing unit, a seeder and the simplified seeder models. Taking into account factors of the agrotechnical requirements of crops influencing their work on providing the equations of the movement of a sowing campaign and the landing car in longitudinally vertical and the horizontal planes are defined. Transfer functions of sowing and planting machines are obtained by generalized coordinates describing the dynamic properties of the seeder. On the basis of the agrobiological and technological indicators of sowing machines productivity, areas for improving the technology of sowing of agricultural crops, modernization of existing sowing machines and the development of new techniques were identified in the field of technology of grain crops sowing.
