Forming and tilling aggregates Ara are intended for forming ridges in the modern cultivation of potatoes and root vegetables. The machine is equipped with active and passive working units, enabling strip soil loosening and forming two broad and permanent ridges with the spacing of 750 mm or 675 mm. First, the soil is treated with passive teeth, then with an active milling drum and the ridges are initially formed with the attachment with ridging bodies. The machine covers two working versions which are distinguished by the arrangement of teeth, copying wheels and tools forming the final shape of the ridges. In the version intended for ridging potatoes, the ridges are formed with a passive profiling attachment. In the version intended for cultivation of root vegetables, the ridges are formed with an active spool shaft. Both versions can be equipped with a seeder dosing the fertilizer directly into the ridges.
