Project summary
Electric walk‑behind tractors are an emerging alternative to small diesel machines for smallholder farmers and local producers, but their sustainability must be assessed across the entire life cycle – from raw material extraction and manufacturing to use, maintenance, and end‑of‑life.
This project conducts a cradle‑to‑grave analysis of Aftrak’s electric micro‑tractor, examining systems such as the battery, motor, drivetrain, and chassis. The research evaluates environmental, economic, and social impacts, identifies hotspots, and highlights opportunities for circularity, repairability, and improved energy performance – providing evidence‑based guidance to advance low‑carbon small‑scale mechanisation.
Meet the researcher
Hi, I’m Rotimi. I recently completed an Integrated Master’s in Mechanical Engineering at the University of Nottingham, where I focused on composite structures and powertrains.
I joined the CDT program in October 2025 to carry out a Life Cycle Analysis on a micro-electric tractor being developed by Aftrak. The variability in how this compact product can be used really intrigued me, and I was keen to explore electric powertrains after studying structures and combustion systems during my degree.
What excites me most about this project is the opportunity to make a tangible impact quickly – bringing sustainable engineering solutions to a product that can transform agricultural practices on a smaller scale.
I chose to join the EnerHy program as it presented an opportunity to develop my knowledge of electric and hydrogen powered systems that will help us get to Net Zero.
