Таким образом поддерживаетс определенное рассто ние рассева удобрений при переменной частоте врашени диска.With the new position III, the nozzle 4 ipa of the flight of the mass of fertilizers decreases due to a decrease in the angle, their descent from the nozzle 4, but additionally the resulting centrifugal forces take the mass to the previous distance or close to it. In this way, a certain fertilizer sieving distance is maintained at a variable disc turn rate.
