ENGINE DETAIL
The Nuffield M3 tractor features a robust 4-cylinder, liquid-cooled engine with a displacement of 3.8 L, producing 38 hp at a rated RPM of 2000, ideal for medium-duty agricultural tasks. Its torque output of 138 lb-ft at 1000 RPM suggests strong low-end power for heavy pulling applications, while the oil bath air cleaner provides superior filtration under dusty conditions. However, be mindful of the 19.2 qt coolant capacity during prolonged operations to prevent overheating in demanding scenarios.

NUFFIELD M3 ENGINE
The Nuffield M3 is powered by a Morris 3.8L 4-cylinder turbocharged engine, known for its robust torque delivery, making it suitable for heavy-duty agricultural tasks. Its total fuel capacity of 26.4 gallons (19.2 gal main + 7.2 gal aux) allows for extended operational time, which is advantageous in large-acreage farming. However, consider weight distribution and fuel efficiency when loading, as a heavier load may affect maneuverability in tighter spaces.

TRANSMISSION
The Nuffield M3 features a straightforward gear system with 5 forward and 1 reverse gear, ensuring adequate versatility for various farming tasks. Its 280mm mechanical dry disc clutch offers reliable engagement but may require more frequent maintenance compared to hydraulic systems. With an oil capacity of 50.4 quarts, the M3 supports extended operation times but necessitates regular checks to prevent engine wear due to insufficient lubrication.

MECHANICAL
The Nuffield M3 features a 4x2 2WD chassis, which enhances maneuverability but may limit traction in challenging terrains. Its manual steering can result in user fatigue over extended use, while the mechanical drum brakes provide basic stopping power, potentially leading to slower response times compared to modern hydraulic systems. The open operator station improves visibility and airflow, making it suitable for light agricultural tasks, but offers little protection in adverse weather conditions.
