Seeding unit
The seeding unit is used on ploughed or mulched soils. The seeding unit includes the grain singling unit, the seed hopper and the seeding coulter. The seed placement depth and the seeding coulter pressure can be adjusted. The seeding coulter is guided over the soil with the depth control wheel. The cutting discs clear plant residues out of the seed furrow area. Together with the furrow former, the cutting discs shape the seed furrow. The singled seed grains are caught by the catch roller and pressed into the bottom of the furrow for good soil contact. Depending on the machine equipment, the seed furrow will either be closed by a press roller or the V press rollers.

Seed hopper
Depending on machine equipment, the fertiliser application point can be changed over with a switch 3. The fertiliser can then be applied in the fertiliser furrow 2 or in the seed band 1. The exhaust air 4 is discharged near the ground.
