Last summer, I worked on the conversion of a Massey Ferguson tractor into a fully electric vehicle as part of the ELAG project at the University of Agder (UiA). Building on the foundation of a 2024 bachelor’s thesis, my work focused on CAD modelling, system configuration, and mechanical design for integrating a Nissan Leaf battery, motor, and inverter into the tractor platform.
The project started with 3D scanning the tractor to create an accurate Digital Mock-up (DMU). I refined the scanned model to ensure a close match to the physical tractor, enabling reliable analysis and design work. Using this DMU, I evaluated multiple configurations of the Leaf powertrain components to identify the most suitable setup for a functional electric tractor. Key considerations included component placement, available space, weight distribution, and overall system compatibility.
Based on the selected configuration, I designed a custom structural frame intended to replace the removed diesel engine block. This frame is planned to take over the structural role of the original engine, supporting mechanical loads while also serving as a mounting structure for the electric drivetrain components.
In parallel with this mechanical and digital development, related work within the project addressed the electronic challenges of using proprietary EV components, particularly CAN Bus communication interpretation and battery system logic by Eivind Greca. His blog post can be read here: https://sifblogg.uia.no/canbus-decoding-of-bms-system-students-in-research/. Together, these efforts highlight the multidisciplinary nature of electric vehicle conversions, combining mechanical design, system integration, and embedded electronics.
This project demonstrates how modern tools like 3D scanners can help create detailed DMUs to test concepts without the need to produce a physical part. A special thanks to Faisal at UiA for cooperation and Mikael at the E-trac project for support. Visit https://e-trac.no/ to learn more.
