What is Spectral Density Function (or Power Spectrum)

Sowing is one of the main operations in the technological complex of cultivation of cereals. Only with high quality seed distribution along the length and depth of the row can the maximum productivity and yield be achieved. A tractor with a seeding machine is subjected to continuously changing external influences that have a negative impact on the performance indicators of the technological operation. Based on the cereal cultivation technology, it is necessary to use tractors with transmissions that can absorb the oscillations and increase the stability of the coulter group of the seeding machine. Since this improves the quality of the operation, reduces the consumption of spent seed and fuel and increases environmental component of the process.
