As the agricultural industry competition becomes to intensity, both delivering the high-quality products with the low cost and reducing the development duration are the most important things to be a successful manufacturer. To keep their heads above water, companies have adopted a process known as Computer Aided Engineering(CAE) Method. CAE Method allows for cheap and effective prototyping of the Electric Tractor(E-Tractor) which is driven by electric power in short time. This paper introduces the CAE analysis of the E-Tractor chassis and applications for the new tractor development.
