The purpose of the study is to develop an energy-efficient technology for vertical-pin tillage, to manufacture and test a prototype of a rotary soil cultivator. At the time of the start of this project and the solution of this problem, two patents were obtained in Russia: No. 2671480 dated October 31, 2018 and No. 2732021 dated September 10, 2020 on the technology of deep pin tillage. In the first version, the technology is implemented using a metal drum with a diameter of 2.5 m or more with pins 25 cm or more long installed on its surface, made according to the principle of a wide bicycle wheel from 3 m or more, fixed by an axle on a frame that clings to a tractor , and the drum, rolling over the soil, loosens the soil under its own weight. The larger the drum diameter, the lower the energy consumption for loosening the soil and the greater the non-technological weight of such a unit. To eliminate this contradiction, a new technology has been developed for loosening the soil with a special rotor subsoiler of soil according to patent No. 2732021 dated 09/10/2020, based on the ratio of the difference in the length of the radius of the drive wheels with a diameter of 3 m with special lugs located on the outer surface of 2 wheels, with a transmission rotational energy from them by pin gearboxes located on the inner surface of the wheels to a subsoiler rotor with a diameter of 50 cm. NPO TEKHNOROS LLC designed and manufactured such a unit and conducted its production tests on an experimental field. An autumn slitting of the stubble field was carried out, the traction resistance of the unit was measured with a dynamometer, at a soil cultivation depth of 15.5 cm it was 3.5 kN/m. The working speed of the unit was more than 12 km/h, and in the presence of 3 sections with a working width of one section of 3 m with a tractor of the K-700 type, the productivity was 10 ha/h.
