The article in hand describes the design and the results of testing of the new device for redistribution of trailing weight between tractor axles and an aggregated agricultural machine. The use of this device for redistribution of trailing weight between a mobile power unit (MPU) – a tractor – and an aggregated agricultural machine (APK 10.8 “Ermak”) intended for secondary tillage is particularly important in the regions which are characterized as “areas of risk farming”. The key feature of such zones is that the main agricultural works take place during the period when the soil has weak load bearing capacity due to high precipitation. The presence of a hard permafrost sublayer exacerbates the issue further. That said, with large areas to cultivate and limited time to perform the necessary agricultural works the use of high-speed high-power wheeled mobile power units is predetermined. It is necessary to note though that this type of tractors put high pressure on the soil, and with the increase of the traction power on the hook they slump down to the permafrost layer and lose their flotation capacity. The most appropriate solution for this problem in the described circumstances is redistribution of trailing weight between the mobile power unit and the agricultural machine. The article in hand aims to present the results of the experimental study of the mobile power unit (the tractor with an articulated frame Buhler Versatile 2425) and the agricultural machine APK – 10.8 “Erkmak” with the integrated device for redistribution of trailing weight. The experiments established that redistribution of trailing weight allows to increase traction and adhesion in mobile power units, boost labor productivity, reduce the technogenic impact on the soil and preserve its fertility.
