The question of the effectiveness of the use of the vehicle fleet in the transport and technological support of the agro-industrial complex is relevant for those regions where a significant amount of precipitation is observed during the main agricultural operations, in particular harvesting. Thus, the state of the driving surface significantly reduces the cross-country capability built into the vehicle by the manufacturer, which fully applies cross-country vehicles. In most cases, cross-country vehicles have the ability to move on surfaces with high humidity, but at the same time, after the passage of their wheel system, a deep track remains. At the same time, it should be noted that if the vehicle moves along a piece of land with high humidity, then after its passage it is necessary to carry out additional agricultural operations to decompact, embed and level the soil layer. Production observations have established that one of the effective ways to solve the problem of overconsolidation along the track of a car is to increase the contact area of the wheel propellers with the driving surface by installing arched tires. This allows not only to reduce the normal pressure of the wheel propellers on the soil, but also to increase the grip of the vehicle when implementing methods for redistributing the additional vertical load on the wheel propellers. The presented article presents the results of comparative tests of the KamAZ-4350 cross-country vehicle on arched tires with a device that allows loading the drive wheels by using part of the weight transferred from the car trailer using an original design device.
