ENGINE DETAIL 1
The Farmall Super A features a C113 gasoline engine with a modest displacement of 1.9L and a low compression ratio of 6:1, which may result in lower power output but enhances fuel efficiency and engine longevity. The rated RPM of 1400 indicates optimal performance for light to medium agricultural tasks, while the idle RPM range of 500-1540 provides flexibility for various operations. Maintenance considerations include a coolant capacity of 13 quarts and specific valve clearances, requiring regular checks to ensure reliability and optimal performance in fieldwork scenarios.

ENGINE OIL
The Farmall Super A has an oil capacity of 5 quarts (4.7 liters), which is relatively modest, making it easier to maintain and change oil. With a recommended oil change interval of 120 hours, it's crucial to monitor usage to prevent engine wear, especially in demanding agricultural applications. Regular maintenance ensures optimal performance and longevity, but farmers should be aware that frequent servicing could be a logistical challenge during peak seasons.

ENGINE DETAIL 2
The Farmall Super A is powered by a kerosene-fueled 4-cylinder engine with a 1.9L displacement, offering efficiencies in fuel consumption at lower operating costs. Its bore and stroke ratios (3.00x4.00 inches) indicate a focus on torque rather than high RPM power, making it optimal for tasks requiring sustained pulling strength, such as plowing. However, the 1400 RPM rating may limit its performance in high-speed applications, so it suits low-speed agricultural operations best.

TRANSMISSION
The Farmall Super A tractor utilizes a sliding gear transmission with 4 forward and 1 reverse gear, offering basic but effective control for small to medium farming tasks. Its 9-inch dry disc clutch provides reliable engagement; however, operators should be cautious of wear under heavy use, as this may necessitate more frequent maintenance. The oil capacity is notably low, with a total of 5qts for PTO/pulley operation, indicating the need for regular checks to avoid overheating and ensure optimal performance.

MECHANICAL
The Farmall Super A features a 4x2 2WD chassis, providing basic traction suitable for light to moderate fieldwork, but may struggle in wet or hilly conditions. Its manual steering offers simplicity and cost-effectiveness, though it demands more physical effort compared to power-assisted systems. The differential mechanical contracting band brakes and 4-speed sliding gear transmission ensure straightforward operation, but the lack of an enclosed cab may limit operator comfort and protection from the elements during extended use.
