The article notes the need to create promising vehicles for agricultural production that meet modern trends in the development of engineering. A brief review and classification of small-sized transport-technological vehicles based on tricycles, incl. on electric traction. An experimental sample of an electric cargo tricycle developed at the FSAC VIM and its technical features are presented. The basic and advanced harvesting and transport technologies used in the selection of grain crops are described. A high level of manual labor and low productivity of basic agricultural technology are noted on the example of a pilot farm in the Ryazan region. The requirements for the design of a cargo electric vehicle based on a tricycle for implementation in a promising harvesting and transport technology have been formed. The concept of a vehicle that meets the indicated requirements is presented. Calculation substantiation and selection of parameters of the traction electric drive and storage batteries are made. A contradiction was noted in the choice of parameters of the traction electric drive by manufacturers of electric tricycles - the drive power is several times less than road resistance, even taking into account the overload capacity of electric motors. The expected economic effect from the introduction of the developed vehicle into a promising harvesting and transport technology is given.
