Abstract

At present, when cultivating various agricultural crops, there is an increased load of machine-tractor units on the soil horizon, due to the use of multi-operational tillage technology. The family of universal high-speed cultivators UKS of 10-, 12- and 14-meters working width simultaneously performs the following technological operations: loosening without turning the layer with cutting and combing out weeds, as well as compacting and mulching the soil surface. UKS cultivators include the following structural elements: a frame with a hitch, a hydraulic system, a disc bar, a frame consisting of the middle and side sections and wings on the transverse bars of which there are five rows of duckfoot paws, support-running wheels, and a scraper frame with seals. In the course of field research of the developed universal high-speed cultivators, it was established that their quality indicators correspond to the agrotechnical requirements: the deviation of the processing depth from the average does not exceed 1.5 cm; the presence of ridges on the surface of the field less than 3 cm high; the number of fractions less than 25 mm in size (crumbling) was more than 80%; crop and plant residues remained on the surface of the field by at least 80%.
