FEASIBILITY OF APPLYING GREEN STAR NAVIGATION EQUIPMENT FOR SOIL CULTIVATION
The authors present the experience of using the navigation equipment Green Star 2 2600 installed on the John Deere 8430 tractor used for soil cultivation on the fields of the "Integratsiya" training centre of Orel State Agrarian University named after N.V. Parakhin. It has been established that the system of black fallow makes it possible to actively combat weeds, and reduces the number of methods for chemical treatment of winter crops in the subsequent year. The research results have shown that when using the free corrective SF1 signal, the deviation from the specified trajectory does not exceed 15 cm. Comparative figures are given for soil treatment with the John Deere 8430 tractor equipped with a disk harrow Catros 7500 unit with navigation equipment and without it. It has been established that for a disk-operated area of 12,000 hectares, at a price for diesel fuel of 45 rubles per liter, fuel consumption of 6 liters per hectare, and with the use of navigation equipment, the economic effect on fuel alone will amount to 193,104 rubles for the season. With an average capacity of 10 hectares / h for cultivating an area of 12,000 hectares without the use of navigation equipment, it will take 71.5 hours more. In addition, navigation equipment provides for 24-hour operation of a machine under conditions of high dust content, which has a positive effect on the time frame of field works. The research results have shown that navigation provides not only for the most effective use of money invested in the equipment, but also to shorten the operating time, increase productivity, while ensuring fuel economy and reducing labor and production costs.
