After the harvest of winter wheat, the tensile force, cross section of loosened soil and specific resistance of soil were measured on a loamy soil plot. During the comparative measurements, 3 blades were used with chisel width of 20 mm, 40 mm and 75 mm. In case of all blades, the measurements were carried out at the depth of 100, 200 and 300 mm. In the course of measurements, the standards of blades were attached in a measuring frame on six-component hinge with connected tensometric sensor. The selected blades were developed for a new type of tiller destined for primary cultivation of soil. Moreover, in case of a blade equipped by chisel there were used side wings of a width of 110, 150 and 200 mm for tillage into a depth of 100 mm. It was found that the width of blade chisels did not have a statistically significant effect on the values of specific resistance of soil during the soil tillage. At all widths of blade chisels, a trend of an increase in specific resistance of soil was recorded at growing recess into the soil.
