ENGINE DETAIL 1

The McCormick-Deering Super W-6 features a robust C-264 gasoline engine with a displacement of 264 ci, providing notable torque at 370 lb-ft, peaking at 997 RPM, ideal for heavy agricultural tasks. However, the low compression ratio of 5.9:1 may limit efficiency and power output compared to modern tractors, potentially impacting performance in high-demand scenarios. Its oil bath air cleaner adds longevity, but entails more maintenance, making it essential to balance operational costs and care for optimal performance.

ENGINE DETAIL 2

The McCormick-Deering Super W-6, powered by an LP gas 4-cylinder engine with a 264 ci displacement and a compression ratio of 6.75:1, provides strong low-end torque at a rated RPM of 1450, making it suitable for heavy-duty agricultural tasks. The oil bath air cleaner enhances engine durability by reducing airborne contaminants, but may require more maintenance compared to dry filters. Operating at 6 volts for starting can present challenges in cold weather, necessitating proper electrical maintenance for reliable starts.

TRANSMISSIONS OVERVIEW

The McCormick-Deering Super W-6 features a 5-speed manual gearbox combined with a 10-speed partial power shift, providing enhanced torque management and operational flexibility for varied agricultural tasks. This transmission setup allows for efficient speed adjustments without the need for stopping, improving overall productivity during field operations. However, operators may face a learning curve with shifting between the manual and power shift modes, which could complicate use for less experienced users.

TRANSMISSION 1

The McCormick-Deering Super W-6 features a 5-speed forward and 1 reverse gear configuration, allowing for versatile speed control suitable for varying field conditions. Its dry disc clutch provides reliable engagement and reduction in maintenance compared to wet clutches. However, while this design offers simplicity, it may present challenges in terms of wear and heat dissipation during extended use.

TRANSMISSION 2

The McCormick-Deering Super W-6 tractor features a partial power shift transmission with a Torque Amplifier, enhancing operational versatility by providing 10 forward and 2 reverse gears. The Torque Amplifier allows for increased pulling power without stalling the engine, making it advantageous for heavy-duty tasks and varied field conditions. However, reliance on older technology may present challenges in maintenance and parts availability compared to modern tractors.

MECHANICAL

The McCormick-Deering Super W-6, with its 4x2 2WD chassis, offers simplicity and ease of maintenance but may struggle with traction on uneven terrain compared to 4WD models. The manual steering can require more physical effort, particularly during prolonged operation, while the mechanical disc brakes provide straightforward reliability but may have lower stopping power under heavy loads. The 5-speed transmission, combined with a 10-speed partial power shift, allows for versatile speed adjustments, making it well-suited for varied field operations and light to moderate towing tasks.
