“…Since we are dealing with time series of the studied indicators, to determine the presence of a trend in them, we will apply the method of comparing average levels, dividing the time series into two parts and test the main hypothesis about their equality by applying the Student's t-test [17][18][19][20][21][22][23][24][25][26]. We will test the null hypothesis H0 about a systemic shift in the time series using the Heaviside function and construct a regression equation [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]. The significance of the parameter with a dummy variable will mean that the hypothesis of the presence of a systemic shift is accepted.…”

The article examines the production of agricultural machinery in the Russian Federation for the period from 2000 to 2020. The aim of the work is to develop a forecast for the production of the main types of agricultural machinery in the Russian Federation in modern conditions. Within the framework of this, the following tasks are supposed to be solved: - study of the availability of agricultural machinery for domestic agricultural producers; - identification of trends in the development of agricultural machinery production; - construction of econometric models that describe the volume of agricultural machinery produced. The information base of the study was the data of the Federal State Statistics Service. The study used statistical methods, in particular Student’s t-test. The null hypothesis about the presence of a systemic shift in the time series was tested using a dummy variable. The index of production potential was also used in the work. Calculations showed the presence of a systemic shift in the series of the studied indicators. Econometric models were built for each series. For the production of tractors and loaders for agricultural purposes, the model will have a mixed look. Combine production is characterized by quadratic functions. Based on the models obtained, the production of the main types of agricultural machinery in the Russian Federation for the period 2021–2023 was predicted.

“…When the unit is moving at high speed, cut weeds do not have time to be thrown aside and stick together with the soil on the rack of the working body, reducing the quality of the cultivation process. Operation in such conditions leads to an increase in traction resistance and long downtime of the unit for cleaning the working bodies [3][4].…”

Weed control is an important technological operation in the cultivation of all types of agricultural crops, especially row crops, vegetables and grains. Since weeds have an increased ability to grow and develop at low temperatures in early agrotechnical terms. Then the fight against them in the preparation of the soil before sowing is a necessary condition for maintaining moisture and obtaining consistently high crop yields. When carrying out agrotechnical measures aimed at weed control, cultivators for continuous tillage are used, which are used for tillage before sowing and when caring for fallows. But when cultivating, the cut weeds overhang on the rack of the working body of the cultivator. This violates the agrotechnical requirements for tillage and reduces the productivity of the unit during cultivation. To eliminate these shortcomings, a device has been developed that provides protection for the cultivator leg rack from overhanging cut weeds during cultivation. The created working body can be installed on the existing frame structure of the steam cultivator without its modification. The operation of a steam cultivator with an improved working body allows you to increase the productivity of work on cultivation by 15%.
