Abstract: One of the peculiarities of lands in the Amur Region is the presence of a solid underlying layer in the form of a clay bed which is located at the depth of 0.3-0.35 m. Heavy precipitation during the harvesting period creates a situation when the upper layer of the soil is quickly saturated with moisture but the solid underlying layer prevents this moisture from being distributed to the deep. As a result, the load-bearing capacity of the oversaturated upper layer declines sharply and it is unable to hold the weight of the harvester. When working on soils with low load-bearing capacity, the wheels of the harvester (combine) which are more loaded slump down to the solid underlying clay layer during the movement and leave a deep track pit thus increasing the technogenic impact on the soil and energy costs. This also, hinders the further operation of the machine. Previous studies on the topic have made it possible to propose a promising method to solve this problem which involves redistribution of the weight load between the wheels of the harvester to even out the pressure on the soil caused by the machine. The study in hand describes the design and lists the results of experimental testing of a new device regulating the weight load of a combine harvester during the harvesting period. The utilization of the proposed device will allow redistributing the weight of the harvester between its wheels, to decrease the normal pressure of the machine on the soil and thus, increase the efficiency of its use.
