The utility model refers to agricultural machinery, in particular to a universal combined modular agricultural unit with replaceable modules for tillage and sowing crops in various ways.The universal combined agricultural aggregate consists of a tillage part which, in turn, consists of three sectional frames with support wheels and a trailing device, onto which, through a linkage mechanism with an automatic coupler, replaceable modules with supporting wheels and various types of working bodies for closing moisture, presowing and basic soil treatments, for steam treatment and for soil chilling.To eliminate the possibility of clogging of plant residues between the frame and the soil surface, the plug-in modules with working elements for covering moisture and presowing soil cultivation have a height of the counter of working bodies ≥0.5 m for steam treatment and basic tillage ≥0.6 m, soil chilling ≥0 , 7 m, while the racks of the working elements are placed on the frame of the module in four rows in the form of a symmetrical wedge with an angle of the wedge forward.When the unit is operating in the variant of the tillage seeder, when the replacement modules are hung on the frame for working with ordinary tools or for loose seeding, with a deep distribution of seeds and fertilizers, a seed and fertilizer bin with pneumatic transportation and distribution of seeds and fertilizers along the openers is established between the tillage part of the unit and the tractor .The introduction of a universal combined soil tillage plant into production will ensure the implementation of all operations of the technological process of cultivation of agricultural crops with one unit with replaceable modules for moisture closure, for presowing soil cultivation with different types of working organs, for presowing tillage and sowing by ordinary or dispersed methods with fertilization depth of seeding, for steam treatment, basic treatment and soil chilling. Thus, one unit replaces the whole
