The first dises open the ground and scalp the surface. They destroy plants by mulching them to accelerate their décomposition. This ensures that the residue does not block the passage of the tines.
By adjusting the tine depth (up to 40 cm), you can either destroy more residue to improve the mulch or decompact the lower layers of the soil. This allows water to penetrate by promoting drainage and root exploration.
The second discs take up the mulch, smooth and level it in order to fully prepare the soil for sowing. A uniform and level mixture promotes residue decomposition and organic activity.
The rollers ensure depth control and machine stability. They consolidate the ground so that it is not too porous. They provide optimal conditions for germination (self-seeding, sowing).
