ENGINE DETAIL
The Nuffield 4/25 features a 1.5 L diesel engine with a 25 hp output, ideal for moderate agricultural tasks requiring reliability. Its oil bath air cleaner offers superior filtration in dusty environments, enhancing longevity. However, with a relatively low power rating of 25 hp, it may struggle with heavier implements, making it best suited for small-scale operations or lighter fieldwork.

TRANSMISSION
The Nuffield 4/25 tractor features a 9 forward and 3 reverse gear configuration, optimizing versatility for various agricultural operations. The 228.6mm dry disc clutch ensures effective power transfer but may require more frequent adjustments compared to hydraulic clutches. It is well-suited for tasks requiring frequent direction changes, such as loader work, but may challenge operators in hilly terrains due to gear ratios.

MECHANICAL
The Nuffield 4/25 tractor features a 4x2 2WD chassis, providing adequate traction for lighter agricultural tasks, though it may struggle in muddy conditions due to the lack of 4WD. The 9-speed transmission allows for versatility in speed ranges, but the manual steering may lead to increased physical effort during operation, especially in tight turns. The mechanical rear differential lock ensures better traction on uneven terrain, while the dry disc brakes provide reliable stopping power but may require more frequent maintenance.

NUFFIELD 4/25 TIRES
The Nuffield 4/25 tractor features a narrow front tire size of 5.50-16, which benefits maneuverability in tight spaces but may reduce stability on uneven terrain. The rear tires, measuring 11.00-24, provide adequate traction and load-bearing capabilities for agricultural tasks, enabling it to handle heavier implements effectively. Overall, this configuration is advantageous for medium-duty fieldwork but may present challenges in rough or hilly conditions due to the front tire's width limitations.

DIMENSIONS & TIRES
The Nuffield 4/25 features front tires sized at 5.50-16 and rear tires at 11.00-24, providing a favorable front-to-rear traction ratio that enhances stability during operation. Its wider rear tires improve flotation on soft ground, making it suited for tillage and hauling tasks. However, the relatively low-profile front tires may compromise handling on uneven terrain, so operators should be cautious when navigating rough fields.
