ENGINE DETAIL
The McCormick-Deering 15-30 features a robust 4-cylinder vertical engine with a substantial displacement of 381.7 ci, suitable for heavy-duty agricultural tasks while operating on kerosene. With a bore and stroke of 4.50x6.00 inches, it delivers a balance of torque and power at a rated RPM of 1050, ideal for low-speed pulling applications. However, the hand-crank starter may pose a challenge for ease of operation, especially in cold weather, and its 48-quart coolant capacity may require careful monitoring during extended usage to prevent overheating.

MCCORMICK-DEERING 15-30 ENGINE
The McCormick-Deering 15-30, powered by a 6.3L 4-cylinder kerosene engine, emphasizes fuel efficiency and operational durability, making it suitable for agricultural tasks requiring extended run times. With an 18.5-gallon primary fuel tank and a 1-gallon auxiliary tank, the tractor supports long working hours but may require careful planning for fuel stops, particularly in isolated fields. Challenges include potential fuel availability issues for kerosene in some regions and lower power output compared to modern diesel engines, but it remains a reliable choice for historical restoration or specialized farming duties.

TRANSMISSION
The McCormick-Deering 15-30 tractor utilizes a simple gear transmission system with 3 forward and 1 reverse gear, providing basic operational versatility for agricultural tasks. This limited gearing can pose challenges in varying terrain or for specific field operations, as it may not offer optimal speed or torque for all conditions. However, its straightforward mechanics make it easier to maintain and repair, making it suitable for small-scale farming or vintage equipment enthusiasts.

MECHANICAL
The McCormick-Deering 15-30 features a robust 4x2 2WD chassis, ideal for moderate terrain and agricultural tasks but may struggle in softer soils or hilly conditions. Its manual steering system provides direct control, albeit with less precision and ease compared to modern power steering options. The 3-speed gearbox allows for flexibility in speed adjustments, but limited to three ratios, it may impede efficiency in varying field conditions compared to multirange transmissions.
