4.9 PreTeC coulter
4.9.1 Seeding unit
The seeding unit is used on ploughed or mulched
soils. The seeding unit consists of 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 crop residues in front of the
coulter on fields with organic material. 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. The press rollers close the seed
furrow.
