ENGINE DETAIL
The McCormick-Deering OS-6 features a 4-cylinder gasoline engine with a displacement of 247.7 ci (4.1 L), providing a balance between power and fuel efficiency for agricultural tasks. Its bore/stroke ratio of 3.875x5.25 inches indicates a long stroke design that enhances low-end torque, making it suitable for heavy tillage and pulling operations. The engine's variable compression ratios allow for versatility in fuel options, although lower compressions may result in reduced efficiency when using kerosene or distillate gasoline.
