ENGINE DETAIL
The McCormick-Deering Super W-4 features a liquid-cooled, 4-cylinder gasoline engine with a modest 2.7L displacement, capable of producing consistent torque at a rated RPM of 1650, making it suitable for agricultural applications. Its low compression ratio of 6.1:1 can enhance durability and ease of starting but may limit power output and efficiency compared to modern engines. Key maintenance points include a 6-volt starting system and specific valve clearances, which require regular adjustment for optimal performance in demanding work scenarios.

TRANSMISSION
The McCormick-Deering Super W-4 features a sliding gear transmission with 5 forward and 1 reverse gear, providing adequate speed variations for different agricultural applications. The dry plate clutch offers good durability and ease of maintenance, but may require more effort for engagement compared to wet clutches. This setup makes it suitable for small to medium farms, although operators may find the gear shifting less smooth under heavy load conditions.
