According to statistical data, in the last decade, the fleet of motor graders was almost not updated, there was a fall in both the production of these machines by domestic industry and purchases from foreign manufacturers. As a result, there was an acute need for machines of this type, and in the near future we should expect an increase in demand for auto graders and, as a result, an increase in their production, since graders produced in Russia are almost equivalent to foreign analogues. Moreover, heavy -class car guards and especially heavy cars will be more popular, as they are more universal in use and have a wider area of application.
