Abstract

Weed control is an important technological operation in the cultivation of all types of agricultural crops, especially row crops, vegetables and grains. Since weeds have an increased ability to grow and develop at low temperatures in early agrotechnical terms. Then the fight against them in the preparation of the soil before sowing is a necessary condition for maintaining moisture and obtaining consistently high crop yields. When carrying out agrotechnical measures aimed at weed control, cultivators for continuous tillage are used, which are used for tillage before sowing and when caring for fallows. But when cultivating, the cut weeds overhang on the rack of the working body of the cultivator. This violates the agrotechnical requirements for tillage and reduces the productivity of the unit during cultivation. To eliminate these shortcomings, a device has been developed that provides protection for the cultivator leg rack from overhanging cut weeds during cultivation. The created working body can be installed on the existing frame structure of the steam cultivator without its modification. The operation of a steam cultivator with an improved working body allows you to increase the productivity of work on cultivation by 15%.
