ENGINE DETAIL
The McCormick-Deering Super WD-9 is powered by a robust International Harvester diesel engine with a displacement of 5.7L, featuring a high compression ratio of 15.6:1, which enhances fuel efficiency and torque output at 1500 RPM. Its 4-cylinder liquid-cooled design ensures optimal thermal management, though maintaining adequate coolant levels (36 quarts) is critical for consistent performance. The gasoline-start system (12 volts) simplifies initial ignition in cold conditions but may add complexity in starter maintenance compared to direct-start diesel systems.

MECHANICAL
The McCormick-Deering Super WD-9 features a 4x2 2WD chassis, making it suitable for light agricultural tasks on even terrain but limiting its traction on steep or muddy surfaces. The manual steering provides simplicity and ease of maintenance, although it may require more effort in tight maneuvers. With a 5-speed transmission, operators can achieve a balance of speed and torque for various applications; however, the open operator station may expose the driver to elements, impacting comfort during prolonged usage.
