ENGINE DETAIL
The J.I. Case 25-45 tractor features a robust kerosene-powered 4-cylinder engine with a significant displacement of 641 ci (10.5 L), delivering substantial torque at low RPM (850). Its bore and stroke dimensions of 5.50 x 6.75 inches provide a long stroke design, enhancing torque at lower engine speeds, ideal for heavy-duty applications like plowing. However, the hand-crank starter may present challenges in operator ease and safety, particularly in colder climates or for less experienced operators.

TRANSMISSION
The J.I. Case 25-45 tractor features a gear transmission with 2 forward and 1 reverse gear, which provides basic control for low-speed tasks but can be limiting in terms of speed variability and operational efficiency. The simple gear layout simplifies maintenance but can challenge adaptability for varied field conditions. Ideal for light agricultural work or small-scale operations, it may not satisfy demands for high-power applications or precision farming where a greater range of gears would enhance performance.

MECHANICAL
The J.I. Case 25-45 tractor features a 4x2 2WD chassis, providing stability for flat terrain but limited traction on hills or uneven surfaces. Its manual steering may require more effort, especially during long hours of operation, while the open operator station offers good visibility, though it lacks protection from elements. The 2-speed gear transmission allows for versatility in speed control, making it suitable for various field tasks, but could pose challenges in fine control during sensitive applications.
