Study of the peculiarities of plant stem architectonics, the anatomical-morphological structure, physico-mechanical distinctions of the substance, theoretical and experimental study of the stem cutting process. The review of the stem cutting as a crack spreading compulsory process based on principles of fracture mechanics, the revelation of the most favorable way of cutting from the kinematic and energetic viewpoint and the processing (designing) of 15 cutting apparatus, laboratory and practical experiments. Theoretical and experimental research is devoted to the development of scientific basis justifying the establishment of the effective vibration control technology, geometric and technological parameters and work regime of the agricultural machinery for mechanizing the laborious activities of the agricultural production
