Global trends in the improvement of combine harvesters

Abstract

It is noted that the use of foreign experience and achievements in the design of domestic machines is one of the effective tools to accelerate the development of agricultural technologies and equipment. The directions of combine harvester improvement and innovations in their designs are given. It was revealed that the most powerful engines (maximum power of 581 kW) are installed on the combine harvesters “Ideal 10” (Fendt company) and “Lexion 8900 Terra Trac” (Claas company). It is shown that the engine power of the most high-performance combine harvesters reached 581 kW. According to the toxicity of exhaust gases, they meet modern requirements. It is found that the technology of selective catalytic reduction SCR is increasingly used in the designs of combine harvesters. They allow to reduce the emissions of toxic substances into the environment by 2-3 times and reduce fuel costs by 40%, as well as the use of natural gas as fuel. It is revealed that the efficiency of using combine harvesters is increased by improving the engines, threshing devices, separation, cleaning, thresher loading and process control systems, working bodies of headers and cutters.
