ENGINE DETAIL
The Nuffield DM-4 tractor features a robust Perkins P4TA diesel engine with a 192.2 ci displacement, providing a balance of power and efficiency suited for agricultural tasks. Its oil bath air cleaner enhances filtration, while a high compression ratio of 22:1 contributes to improved torque at rated RPM (2000), making it advantageous for demanding field operations. However, the relatively high bore/stroke ratio (3.50 x 5.00 inches) may present challenges in terms of engine longevity if not properly maintained, particularly under heavy loads.

TRANSMISSION
The Nuffield DM-4 tractor features a simple gear transmission with 5 forward and 1 reverse gear, allowing for straightforward operation and ease of use. This gearbox configuration is advantageous for general agricultural tasks, providing decent torque across varying speeds; however, limited gear options may restrict performance in more demanding terrains. Operators should consider the tractor's intended applications, as more complex tasks may require additional gear ratios for optimal efficiency.

MECHANICAL
The Nuffield DM-4 tractor offers a 4x2 2WD chassis, emphasizing simplicity and lower maintenance in less demanding terrains, though it may struggle with traction in slippery conditions. Its independent mechanical contracting band brakes provide reliable stopping power but may require more frequent adjustments compared to hydraulic systems. The open operator station enhances visibility and airflow, but operators may experience exposure to harsh weather, necessitating protective gear in adverse conditions.
