STUDYING OF THE USE OF A WHEELED TRACTOR AND THE UPGRADED DISC HARROW

Abstract

Timely preparation of the soil for the future harvest is one of the main tasks facing agricultural producers in the Amur region. There are a number of reasons related to the features of the natural production conditions of the region: late harvesting of branded legumes (soybeans) and abundant precipitation during the spring and autumn field and harvesting operations. (Research purpose) The research purpose is increasing the efficiency of using machine-tractor units during harrowing by improving the design and technological parameters of disc harrows. (Materials and methods) The article presents the device that allows adjusting the coupling weight in the scheme of a machine-tractor unit, for which RF patent No. 196181 was applied. The article also presents photos of the general types of connection of the device with the disk harrow frame, the processing depth was measured. (Results and discussion) All fields suitable for agricultural activity in the region have been developed and used by large agricultural producers, the remaining land reserves consist of slope and small-contour fields, small in size, operated by peasant farms. In small farms, the machine-tractor fleet consists of several units of tractors and a small set of agricultural machines for completing machine-tractor units. (Conclusions) The issue of increasing the efficiency of using machine-tractor units for peasant farms in the Amur region is relevant and requires a modern solution. The article presents the results of research on improving the efficiency of using a tractor unit consisting of a class 1.4 tractor and a BDT-3 disc harrow by increasing traction properties and improving the quality of soil preparation.
