Soil tillage processes significantly affect the growth of cultivated plants; therefore,
improvement of various designs and combinations of ploughs is still an actual practical and
scientific task. This paper presents investigations of the design of a soil tillage machine consisting
of three plough bodies equipped from the lateral side with a module with a flexible active harrow
driven by a support wheel. The technological process of tillage by this machine is carried out in
such a way that the module of the flexible active harrow is installed at a certain depth of soil
tillage. The purpose of this work is an experimental comparative investigation of the quality
indicators of the work of a design of the soil tillage working body with a flexible active harrow
having loosening teeth. In the process of comparative experimental investigations of the operation
of ploughs with a standard flexible harrow and an experimental active harrow having loosening
teeth, the soil lumpiness (characterising the quality of crumbling) and water permeability of the
obtained soil structure were estimated. An experimental model of this working tool was tested
under the production conditions, and it showed advantages of loosening and crumpling the soil
compared to the conventional harrows. This can be explained by the fact that the harrow tines,
freely mounted on the axes of its links, ensure their oscillatory movements when moving in two
different planes, thereby creating conditions for more intense soil disintegration.
