SUBSTANTIATION OF THE WORKING WIDTH OF THE TILLAGE IMPLEMENT.

The paper presents the results of theoretical and experimental studies on the substantiation of the working width of the tillage implement for deep tillage. The field experiment was conducted using the «Kirovets» K 744P2 tractor, with an engine power of 257 kW and an operating mass of 17,000 kg. It was revealed that the optimum working width of the implement should be 4.9-5.6 m at the travel speed of 2.2-2.0 m/s respectively. This provides a working capacity of 3.9-4.0 ha/h, with the fuel consumption of 13.7-14.1 kg/ha. The optimization criteria for selecting the optimum working width were the working capacity and specific fuel consumption per hectare. The data obtained based on the experimental studies are comparable with the results of theoretical studies, which indicates the reliability of the developed mathematical model for determining the working width of the agricultural implement.
