The important height of the band of seeding and an intensity variable vibrator, allows a gradual selection in the pans, so that an only seed remains lodged in the cups.
The cups that take the seed from the seed-box are put spaced on the band to allow the seed in excess to directly fall in the seed-box.
The tandem system between the ploughshare and the limit-switch wheel of depth, guarantees a constant depth of seeding.
Two disk blankets adjustable in width, depth and pressure on the soil, cover the seed without this moves on the row and forming a furrow as desired it.
