ENGINE DETAIL
The McCormick-Deering O-6 tractor features a 4-cylinder liquid-cooled gasoline engine with a displacement of 247.7 ci (4.1L), ideal for agricultural tasks demanding reliable power. Its variable compression ratios allow for versatility in fuel use, with high compression for gasoline and lower for distillates and kerosene, though this can complicate fuel management in diverse applications. Operating at a rated 1450 RPM, it provides adequate torque for demanding work, but may face challenges in high-load conditions without optimal gear ratios.
