Abstract
A comparative assessment of the compliance of the compacting effect of the MTZ-80-2PTS-4M (tractor transport aggregate) movers with the established standards on the soil under operating conditions was made. The average density of soil composition on the stubble and the field for sowing in the horizon of 0-50 cm along the track of the trailer with a minimum and maximum load on the mover exceeded the control data by 28.9-31.2% and 38.2-42.3, respectively. The increase in bulk density and hardness of the treated soil was higher on average by 9.5-11% and 5.5-9.5%, respectively in comparison with the stubble background. The excess of the established norms for the mechanical impact of movers on the soil for the maximum specific pressure was 35.3-45.9% over the entire range of loads on the mover and for the maximum normal stress in the soil was 21.9% at maximum load. Under test conditions, the running system of the 2PTS-4M trailer did not ensure compliance with the established standards for the impact on the soil within the entire range of changes in operational loads on the movers.
