A progressive direction in the development of mechanization for pre-sowing tillage is the use of tillage machines or aggregates with combined working bodies, which make it possible to combine several operations in one technological process. The subject of the study is the energy performance of the unit with combined working bodies. The object of the study is the OKP-7N cultivator intended for pre-sowing and other types of cultivation to a depth of 3 to 15 cm. When performing the work, experimental studies were used using the interaction of working bodies with the soil. The processing of the field section was carried out in the II, III and IV gears of the tractor with the maximum fuel supply. The speed of movement of the unit on the indicated gears was determined in triplicate, the depth of tillage was kept constant at the level of 0.15 m. cultivator. When the unit was operating in the fourth gear of the tractor, the engine overload mode was observed, so the speed of the unit decreased even compared to the speed in the third gear, and the traction resistance of the cultivator was at the same level. The hinged connection of the cultivator without a blocker provides longitudinal copying of the field surface of the tractor separately, and separately of the cultivator, as a result, the traction resistance of the cultivator decreases by 8 … 10%, the speed of the unit increases by 31%, when the tractor is operating in the rated load mode.
