The development of biologization of agriculture focus on the necessity of soil chemical load reduction. The use of a chemical method of weed control leads to herbicide resistance in some weed species. It requires an increase in application dose or new chemical product designing, which ultimately will contribute to even greater environmental pollution. The development of crop cultivation technologies is aimed to enhance mechanization level, proper and timely care of crops, to ensure processing quality that guarantees realization of the variety (hybrid) potential in these climatic conditions. An important element of mechanized farming of corn crops is row-to-row treatment in order to destroy weeds and improve soil water-air regime. The objective of the work was to determine the optimal parameters of the cultivator for row-to-row processing of corn in Amur region. Theoretical features of weed cutting with a goose foot share, the work of chisel and scuffle knife were considered. Working bodies were applied in two combinations, two one-side scuffle knives (razors) with a goose foot share, and two universal goose foot shares
with a chisel and wheel spiders. The first combination showed the best preliminary results and was selected as the most optimal. To determine the operating parameters of the working process of a machine-tractor unit consisting of a tractor and a tilled cultivator with the previously selected optimal combination of working bodies, a full-factor experiment 32 was conducted. With a tractor operating speed of 9.4–10 km/h and a processing depth of 12.2–13.5 cm, weed removal in the row spacing of corn crops was achieved by more than 60%.
