EV Conversion: How a Massey Ferguson 65C Became an Electric Tractor

Electric vehicle (EV) conversions are gaining traction, not just for cars but also for industrial and agricultural machinery. One standout project is the transformation of a Massey Ferguson 65C tractor into a fully functional electric vehicle. Spearheaded by Liam Tronics, a DIY engineer and content creator, this project demonstrates how classic farming equipment can be modernized with electric power while maintaining its core functionality.

In this article, we explore the details of the EV conversion, covering the engineering process, key modifications, and real-world applications. From the removal of the petrol engine to the integration of a software-controlled clutch system, this project is a fascinating example of what’s possible with ingenuity and technical know-how.

Transforming a Vintage Tractor into an EV

Converting a Massey Ferguson 65C into an electric vehicle involved more than just swapping out the petrol engine. The goal was to create a fully functional EV tractor capable of handling practical farm tasks while maintaining its original features.

Initial Modifications:

  • The petrol engine was removed and replaced with a high-torque electric motor.
  • Existing mechanical components, such as the three-point hitch, were retained to ensure compatibility with farming implements.
  • The drivetrain was reconfigured to work seamlessly with the new electric power system.

Performance and Functionality:

  • The newly electrified tractor proved powerful enough for various farm applications, including soil tilling and equipment towing.
  • A tug-of-war test against a car demonstrated the impressive torque of the electric motor.
  • The conversion not only enhanced efficiency but also made the tractor quieter and emission-free, making it ideal for indoor use.

This project highlights the potential for electrifying classic farm machinery, proving that EV technology can extend the lifespan of vintage equipment while reducing environmental impact.

Engineering the EV Conversion

Turning a Massey Ferguson 65C into a fully electric tractor required careful engineering, particularly in power management and control. Rather than simply installing an electric motor, Liam Tronics implemented a series of modifications to ensure the tractor remained functional for real-world farm tasks.

Powertrain and Control System:

  • A high-torque electric motor replaced the original petrol engine, providing sufficient power for heavy-duty applications.
  • Battery management was optimized to maximize efficiency while keeping the conversion practical for long-term use.

Battery Metrics

Clutch Mechanism and Drive Control:

  • Unlike standard EVs, tractors require fine-tuned power control, especially for tasks requiring precision.
  • A traditional clutch wasn’t an option, so Liam developed a software-controlled throttle and clutch system.
  • Using an ATtiny85 microcontroller and a custom PCB, he programmed the system to regulate power output based on pedal input.

Hydraulic System Integration:

  • The three-point hitch on the Massey Ferguson 65C originally relied on the petrol engine.
  • To maintain full hydraulic functionality, the system was modified to work seamlessly with the electric motor.

By incorporating these enhancements, the tractor retained its original usability while embracing the advantages of electric power. The careful balance between mechanical and electronic control systems ensured that it remained a capable farming tool.

Real-World Performance and Future Potential

With the conversion complete, the electric Massey Ferguson 65C has been put to the test in real-world scenarios. The results showcase the impressive capabilities of this retrofitted machine, proving that classic farm equipment can transition to electric power without sacrificing performance.

Practical Applications:

  • The tractor’s power output was tested in a tug-of-war against a car, where it easily outperformed its opponent, highlighting the high torque of the electric motor.
  • Equipped with its original three-point hitch, the EV tractor remains compatible with standard farming implements, making it a useful tool for agricultural work.
  • The quiet operation and zero emissions allow for indoor use, making it ideal for enclosed farming spaces.

Battery Life and Expansion:

  • The current battery setup provides around 30 minutes of runtime, which is suitable for short tasks.
  • By adding additional battery packs, the tractor’s operational time could potentially double or even triple, making it more viable for long-term farm use.

Future Upgrades and Possibilities:

  • Further enhancements could include solar-powered charging to extend runtime and reduce dependency on external power sources.
  • Advanced motor controllers could improve efficiency and precision in handling farm tasks.
  • With growing interest in sustainable agriculture, similar EV conversions could be applied to other types of farm machinery.

This project serves as a proof of concept for how vintage agricultural equipment can be electrified, offering a more sustainable and efficient alternative to traditional fuel-powered machines.
