The Nuffield 4M was a popular and versatile tractor produced by the Nuffield organization, a British company that later merged with the British Motor Corporation (BMC). This model, introduced in the 1950s, was a mainstay in agriculture for many years, known for its reliability and rugged construction. The Nuffield 4M was a compact tractor, but powerful for its size, and offered several engine options to meet different needs. A three-cylinder diesel engine, the OEC, provided a balance of power and economy, while the four-cylinder OEA diesel offered increased horsepower for heavier tasks. The petrol/paraffin engine, the ETC or ETD, was also available for those desiring a more easily maintained fuel source. The Nuffield 4M was well-regarded for its simple design and ease of maintenance. Features such as the robust transmission, the reliable hydraulic system, and the straightforward electrical system allowed for many repairs to be undertaken by the owner. This made the 4M a particularly attractive choice for small farms and hobby farmers, who could rely on its robust construction for years of service. The 4M was a versatile tractor, adept at tackling a wide range of tasks, from plowing and cultivating fields to operating implements like loaders and mowers. Its agility and maneuverability were also appreciated in situations where space was at a premium. The availability of optional equipment further broadened the 4M's capabilities, making it an immensely popular choice for a variety of agricultural and industrial applications.
