The electric tractor (ET) was fabricated and tested as an innovative approach in providing conventional agricultural machinery which puts emphasis on zero emission and potential acceptability for women and the aged. The objectives of this study were to propose the prototype and investigate its performance for the sake of further improvement. The ET was fabricated by converting a 20kW diesel tractor. The performance tests were focused on the energy consumption and drawbar pull characteristics of the ET. As the full-charge capacity of the battery used was 7.2kW·h, the energy consumption and driving range were found to be 0.60kW·h/km and 8.35km, respectively. This performance showed an insufficient level, when considering farming requirements, due to the limited amount of battery supply as well as power transmission losses. However, the ET offered better drawbar pull performance. Since its overall mass was 1065kg, it could attain 5.76kN with 14% slip and 3.89kN with 22% slip on asphalt and hard soil surfaces. The overall efficiency of the ET in transforming electrical power to the power available at the drawbar was 0.21-0.32 on asphalt and 0.17-0.24 on hard soil surfaces. In addition to this, the forthcoming design concept and further refinement were discussed.
