It is necessary to evaluate the motion of vehicles on tilled soil not only from viewpoint of a pressure effect on the soil, but from viewpoint of a traffic frequency, a horizontal load distribution, a motion speed and a wheel sinkage, too. The result force components of an affecting agricultural machinery are not only function of a total machine weight, but of a way of a weight transfer and a force affects, too. In the paper are presented some results of penetration measurings at a soil compaction studies during characteristic field operations obtained by penetrometer P-BDH-3A and a new data processing method of results with aid transformed penetrograms. Graphs with an isoline applications of penetration resistance and a corrections of wheel track depth characterize a dynamics of soil property changes in a dependence on soil horizon very good, which is most important from a machinery affect point of view. At the present is emphasized an accurate monitoring of environment and plant properties, which are utilizing at precision agriculture, therefore an improvement of a measuring methods and data processing receive a great importance
