NOTE

Operating conditions such as the grain shape, dressing or the addition of talcum affect the correct selection of the singling discs. The selection of the singling discs width must be adapted to the respective operating conditions and can only be determined during field operation.

The sliding shutter position and fan pressures are reference values.

The seed settings can be found in the table.
Adjust the fan speed.
Adjust the seed singling unit.
Adjust the PreTeC mulch seeding coulter.
