| 1 | Loosening zone. The loosening depth ranges from 20–40 cm. Loosening shares with optimised geometry arranged in two rows ensure excellent soil loosening and intensive mixing of the soil with crop residues. |
| 2 | Furrow-levelling zone. Levelling discs also increase the effect of incorporating crop residues. |
| 3 | Clods crumbling and soil compaction zone. Optimum soil re-compaction ensures good water infiltration and soil water capillarity to the surface. |

Proper selection of the type of the rear roller contributing significantly to the final quality of the tillage is very important. The soil is recompacted by the roller and then it is the same way crumbled and levelled. The selection of the type of the roller depends on the soil type and on the manner of use of the machine.
