Abstract: One way to reduce soil compaction is to reduce agricultural machines vertical load, thus reducing the weight of the machine. But the weight of the machine can be reduced to a certain limit. One of the ways to streamline the distribution of load on the soil - to change the air pressure of the tires allowing on the soil physical and mechanical properties. Investigations were carried out before the autumn sowing a light sandy loam field. Before the study soil was plowed at 20 cm depth. Soil moisture at a depth of 5 cm was 12%. The studies found less than 19 MPa soil pressure at 0.5 bar pressure in the tires, soil hardness was less than 4.8 times, at the 5 cm depth and at the sole of arable pad less than 4.1 time
