Highlights Built a functional electric drive system of a crawler tractor for greenhouses. Properly integrated the electric components into a traditional tractor. Performed field rotary tillage, field transport, and plowing energy consumption tests to verify the correctness of the matching of the core components of the power transmission system and some performance of the prototype crawler electric tractor. Abstract. Greenhouses are among the most rapidly developing sectors of the Chinese agricultural industry, and they require considerable mechanization. Currently, the machinery used in greenhouses mainly include micro cultivators powered by internal combustion engines. The micro cultivators have various problems such as small output power, low operating efficiency, and poor quality. Also, they harm the growth environment of crops and the working environment of farmers due to gas emissions and noise. In this study, a crawler electric tractor suitable for greenhouses is proposed. It can function in small working areas and narrow working spaces. The electric tractor is suitable for towing, transportation, lifting, and power output. A power transmission system scheme was designed for the electric tractor and a parameter matching method for the core components of the power transmission system is proposed. The prototype of the electric tractor was manufactured and underwent field rotary tillage, field transport, and plowing energy consumption tests. The results of rotary tillage a...
