DEPENDENCE OF THE RESISTANCE TO THE MOVEMENT OF TRACTOR UNITS ON THE VARIABLE WEIGHT AGRICULTURAL MACHINERY.
Increasing power ratio tractors and technology in crop production has led to mass growth outpaced of the technological part of the MTA regarding the growth of the mass of the tractor, making it impossible for him to use as a tractor and calls for new destinations using the power of its engine. . Note that the movement resistance force change unit arising from variable properties of the processed material and heterogeneity of the properties of the working machine and their adjustment. To evaluate the effectiveness of such technical systems, including moving objects and processes, effectively using the method of state variables based on the notion of state. Possible direction to address this issue is the use of control systems, which can adjust the regulating effect on the tractor unit considering the gains of the tractor unit for speed and weight, and automatically change modes of operation. It is also necessary to develop criteria for the selection of this mode in the field.
