Gaps can be caused by insufficient seed in the grain singling unit.

The grain shape or the dressing can cause the seed to be poorly conveyed.

NOTE
Talc in the seed shortens the cleaning interval of the opto-sensor.
Do not use graphite. Graphite disturbs the function of the opto-sensor.
  1. Check the position of the sliding shutter.

  2. To improve the sliding capacity of the seed:

    Mix 1,6g of talcum powder into 1kg of seed

or

Mix 500g of talcum with 40 units of 50,000 grains each.
