One of the most promising configuration schemes for cultivator fertilizer involves a fertilizer hopper mounted directly to the tractor frame. This configuration reduces the energy cost of overcoming the traction resistance generated by the cultivator fertilizer and increases its field capacity. The aim of this study is to evaluate the efficiency of the developed cultivator fertilizer with a tractor with an effective engine power of 300hp under the soil and climatic conditions of the northern region of Kazakhstan. The main scientific achievement of this work is the identification of patterns of change in energy and operational indicators depending on the operating modes of the cultivator-fertilizer device with an attached tractor in the soil and climatic conditions of the northern region of Kazakhstan. Scientific methods such as physical modeling, analysis and synthesis were used in experimental research. Based on the criteria of maximum field capacity and minimum specific fuel consumption, the optimum operating speed for the cultivator fertilizer was 9km/h. At this operating speed, the specific fuel consumption was 9.4kg/ha and the field capacity was 5.7ha/h. The agronomic evaluation indicators (soil crumbling, stubble preservation, deviation of the actual depth from the specified value and uneven fertilizer distribution) ensure the qualitative execution of the technological process in accordance with the specified requirements when operating in the justified mode. Compared to the comparable model, the use of the new cultivator-fertilizer resulted in a positive economic effect, including a 22% reduction in direct costs and a 15% reduction in labor costs and specific fuel consumption. This study was designed to achieve this goal.
