Analysis of designs and technological parameters of chisel plows and subsoilers

Introduction. Improvement of soil tillage processes is the key to quality cultivation of various crops in agriculture and forestry. It is necessary to introduce minimum tillage with minimum energy and labor inputs, providing optimal soil wellness. Deepening of arable layer brings positive results. Creating more favorable conditions for the development of the root system and root nutrition of plants.
Object. The object of research is the design of chisel plows and subsoilers, and their working parts.
Materials and methods. Data was collected in the Yandex search system, as well as in other electronic libraries and information and analytical portals (eLIBRARY, Base, Google Scholar, Springer Link, CyberLeninka). The information was systematized using cluster analysis. Using the computer software package Microsoft Excel and STATISTICA, horizontal dendrograms of similarities and differences in the parameters of the studied aggregates were constructed. The distances between objects were specified as the Chebychev distance metric, and the Unweighted pair-group centroid method was used as a measure of cluster connection. The search for publications was carried out by year from 2014 to 2024.
Results and conclusion. A brief review of loosening working bodies shows that the existing tools have both individual advantages and disadvantages. The analysis of modern working bodies of chisel plows and deep loosening plows has allowed to find ways of further improvement of designs of produced serial implements, which will allow to reduce costs for soil tillage and will be deprived of their disadvantages. The optimum scheme of arrangement of working bodies in the machine – in two rows in staggered order – has been chosen.
