The values of pressure exerted by the soil in four points of attack surface at four plough velocities (5.21, 6.52, 7.33 and 7.78 kmźh-1) during cultivation of silty soil were stated. Under test conditions a large diversification of soil impact on ploughshare surface had a place. The highest values were in the measurement point localized at the tip of share (from 123.9 to 191.2 kPa) and the lowest - within the initial area of trapezoidal part of ploughshare (from 1.4 to 3.7 kPa). In the measurement point localized at the ploughshare tip an increase of plough speed responded to an important increase of soil pressure (approximately 14; 23 and 54% along with increasing plough speed of circa 25; 41 and 49%). In remaining measurement points distinct regularities have not been found.
