The article is devoted to the problem of increasing the efficiency of using mobile agricultural aggregates by reducing the impact of their running systems on the soil. The work on the efficiency of the use of mobile agricultural units based on the automobile chassis in agroindustrial production is analyzed, which shows the results of studies on the changes in their designs with the purpose of reducing the harmful influence of chassis running systems on soil. One of the ways to reduce the harmful influence of running systems of mobile agricultural units on Execution of technological operations, both in field conditions and in transport operations while driving along the road Mobile roads. The main ways that will ensure the effective use of the automobile chassis in field conditions and on highways are analyzed. It has been found that the most effective is the equipment of automobile chassis with wide – profile tires with adjustable internal air pressure and a tire – pumping control system, which makes it possible to effectively use the chassis both in the main technological operations (in the field) and in transport operations (on the roads). The influence of the air pressure in the tire of the wheel of the running system of the KrAZ – 6322 automobile chassis and the normal load on the contact area of the tire with the supporting surface and pressure on it is established. To use the automobile chassis for performing agricultural operations in field conditions, it is necessary to equip it with wide – profile tires with adjustable internal air pressure and a tire – pumping monitoring system that will reduce the negative impact on the soil of the mobile agricultural unit and expand the list of technological operations on which it can be used.
