ENERGY ASSESSMENT OF TURBODISC CULTIVATORS FOR VERTICAL TILLAGE

The purpose of the research is to conduct an energy assessment of serial turbodisc cultivators for vertical tillage. Turbodisc cultiva-tors were evaluated by analyzing the characteristics of turbodisc cultivators from Agrifest-Express (12 models), Salford (21 models). The indicators of turbodisc cultivators are considered, which include the width of the grip, the required power and productivity. Based on these indicators, the energy indicators of the turbodisc cultivators of the companies Agrifest-Express and Salford were determined, depending on the depth of processing. These indicators included the energy intensity of the turbodisc cultivator, its specific efficiency at the processing depth, the specific power per 1 m of the width of the turbodisc cultivator. The statistical values of the characteristics of turbodisc cultivators from the companies "Agrifest-Express" and Salford are given. The energy indicators of turbodisc cultivators from Agrifest-Express and Salford companies have been determined. Salford turbodisc cultivators have a larger grip width compared to the Agrifest Express, and they also require tractors with a capacity of over 310 hp, the range of required power is 96 ...604 hp, their productivity is lower compared to the Agrifest Express. The average energy values of Salford turbodisc cultivators are higher compared to the Agrifest Express with a difference E = 45%, N = 19...76% at different processing depths and Kd = 19%. With all their diversity, the TDK-1420/96 model of the Agrifest-Express company has become the most widespread, which has the following energy indicators: energy intensity – 12.95 kWh/ha, specific efficiency – 383.28 kW/ha, specific power per 1 m of width – 19.16 kW/m. At the same time, this model will allow processing an area of 0.000071...0.000288 hectares with different processing depths – 0.05...0.06 m.
