ENGINE DETAIL
The McCormick-Deering WD-40 features a robust 4-cylinder diesel engine with a high compression ratio of 17:1, which enhances thermal efficiency and torque output, making it suitable for heavy-duty agricultural tasks. However, the hand-cranked gasoline start may be cumbersome and less reliable compared to electric starters, especially in adverse conditions. With a displacement of 460.7 ci, its oil bath air cleaner contributes to improved engine longevity, making the tractor a reliable choice for prolonged use in rugged farming environments.

TRANSMISSION
The McCormick-Deering WD-40 tractor features a 3-forward and 1-reverse gear configuration, providing basic versatility for agricultural tasks. The dry disc clutch ensures efficient power transfer, though it may require more frequent maintenance than a wet clutch system, particularly in dusty conditions. This tractor is suitable for light to moderate farming activities, but operators should be aware of its limited gear range when tackling diverse terrains.

MCCORMICK-DEERING WD-40 TRANSMISSION
The McCormick-Deering WD-40 tractor features a 3-speed gear transmission, enabling versatility for various agricultural tasks. This gearbox allows for efficient power management and speed control, suitable for both heavy tilling and lighter tasks. However, the limited speed range may challenge operators requiring faster transport between fields.
MECHANICAL
The McCormick-Deering WD-40 features a two-wheel drive system, which enhances maneuverability on flat terrains but may struggle in off-road conditions. Its manual steering provides a direct and responsive feel, though it may require more physical effort in tight turns or rough terrains. The spur gear final drive offers reliability and simplicity but can result in higher noise levels and potential wear under heavy loads.
