This paper deals with the concept design of a mini tractor which is suitable for mild ploughing operations with 5 kW electric motor. The low cost battery driven mini tractor operates on a lead acid batteries. The design principles and calculations of electric tractor powertrain are studied and delineated in details. By using these calculations, parameters of the main components like drive motor, battery and transmission are obtained. The powertrain model of an electric tractor is modelled with MATLAB/Simulink to estimate the tractor and battery performance. The CAD model of tractor is done in Solidworks and CAE analysis of chassis is performed to ensure safety and reliability. Calculations are performed for tractor subsystems such as steering system and braking system. The analysis results confer the design as safe and satisfactory in terms of performance. Keywords: Electric tractor, CAE analysis, MATLAB/Simulink.
