Wear resistance of the active working components of a rotary-cultivator and its impact on agrotechnical performance indicators

Abstract

This article provides a comprehensive analysis of the significance of rotary cultivators in agricultural
production and the problems associated with the wear of their working parts. It is highlighted that the
wear of rotary blades significantly reduces soil cultivation quality, diminishes the effectiveness of weed
control, and negatively affects overall production efficiency. The study scientifically demonstrates that
the physical-mechanical properties of the soil — including density, hardness, moisture content, and the
amount of abrasive particles — directly influence the service life of the cultivator’s working parts.
Furthermore, the effectiveness of using high-carbon steels, various heat treatment methods, and wearresistant
coatings to increase the lifespan of working components is discussed. By comparing domestic
and foreign experiences, the research shows that the degree of wear depends on the type of construction
material and the level of thermal processing of the blades. The author proposes promising technological
solutions aimed at extending the service life of rotary cultivator working parts, including the introduction
of innovative technologies, rational use of local raw materials, and comprehensive field testing. These
findings provide a scientific basis for improving the efficiency of agricultural machinery, enhancing soil
cultivation quality, and optimizing production resources.
