The invention relates to an equipment for the soil deep loosening, breaking, settling and levelling, up to a depth of 80 cm, in soils which require the breaking of the impervious soil layer formed under the plough-layer which is highly compact, with low permeability to water and with massive structure. According to the invention, the equipment consists of a metal frame () provided in its front part with two eyelets () intended for attaching, by means of a lower bolt (), a device () which is in connection with the mechanism for three-points suspension of a wheeled tractor and which is connected, by means of an upper bolt (), to a hydraulic cylinder () used for driving it into the transport or working position, while in its rear part it is provided with a pipe of rectangular cross-section (), having a central plate () for a mechanism which drives some active components (), comprising a cardan drive (), a straight bevel reducing gear (), a coupling () with resilient bolts and an eccentric (), at the top lateral sides there being provided two plates () for two supports () of the two deep loosening components of the vertical mobile active blade type (), each of them being articulated by a special bolt () with a chisel-like share () and, at the bottom lateral sides there being provided two eyelets () for articulatedly mounting, by means of some bolts (), two arms () sustaining a frame () on which a roller () with metal spikes is mounted by means of some bearings, known per se, at the rear lateral sides there being two plates () with holes (), two bolts () being fixed in each of them for adjusting the working depth by limiting the zone of vertical oscillation of the roller () with metal spikes, as well as two wheels () for additional adjustment of the working depth, which are articulated by some bolts () into two eyelets () located in the top front part of the pipe of rectangular cross-section (), which are adjustable by means of a left/right screw-nut mechanism ().Invenţi
