The article is dedicated to improving the working components of wide-row chisel cultivators, which play a significant role in soil preparation before planting in Uzbekistan’s agriculture, directly impacting crop yield and resource efficiency. It analyzes the influence of the fourth variant of working components (arranged in a staggered pattern, with a coverage width of 140 mm in the first row and 260 mm in the second row) on agrotechnical and energy performance indicators. The study experimentally examines the effects of different working component arrangements on soil tillage depth, fraction distribution, surface and subsurface irregularities of the tilled layer, and traction resistance. The research results highlight key directions for developing resource-efficient chisel cultivators with minimal soil impact, compatible with modern high-power tractors. The article contributes to the advancement of scientific and practical approaches aimed at modernizing soil tillage technologies in Uzbekistan’s agricultural conditions.
