The rollers are used for pre-and post-sowing soil rolling during the cultivation of winter rape, alfalfa and grain crops.
For pre-sowing preparation of soil for sowing field crops (especially small seeds), it is effective to use rollers that are installed on tillage units behind their working bodies.
They are intended for leveling the surface of the field, crushing lumps and soil compaction. The ribs on the rollers can be round, rectangular and wavy. Rectangular plates come with cutouts and serrated.
The spring harrow when working due to vibration provides loosening of the soil, leveling the surface of the field, removing small weeds, planting fertilizers and even distribution of plant residues.
