Calculation of the amount of seeds/meter for the seed plates
The amount of seeds for every seed plate can be found by making the calculation
below, which has a factor for every sprocket combination (scheme 01).
* These factors represent the amount that the seed plate turns at every linear
meter.
How to calculate:

Make the calculation using different factors and find the combination that distributes
the desired amount of seeds using the chosen seed plate.
