Checking the grain spacing

The application rate determines the required grain spacing. The selection of the singling discs and of the singling disc speed determines the grain spacing.

  1. Spread seed for 30m at working speed.
  2. Use the read-off edge of the multi-placement tester to remove the earth in layers.
  3. Expose 11 grains in one row.
  4. Place the multi-placement tester horizontally on the ground.
  5. Measure 10 grain spacings with the ruler 1.
  1. Calculate the average grain spacing.
  2. Cover the seed with fine soil again.
