Used for subsurface tillage and subsurface decompaction, simultaneously with surface tillage. By the aggregate usage a preliminary disking of one-two trails is recommended. To make a solid topsoil tillage it is necessary to equip working bays with lamps of lancet type with width not less than 270 mm. For pan (sole shoe) decompaction the rigid bays are equipped with chisels.
