Heritage:
Nuffield tractors were a significant part of British agricultural machinery manufacturing, known for robustness. Part of the larger BMC (British Motor Corporation) agricultural division.
Development:
The 'Mini Tractor' designation suggests a smaller, utility-focused tractor within the Nuffield range, designed for smaller farms, horticulture, or general estate use.
Production Era:
Likely produced from the late 1950s through the 1970s, coinciding with BMC's tractor manufacturing period.
