ENGINE DETAIL
The ATC 256 tractor's Continental F-140 engine, with a displacement of 2.3 L and producing 36.5 hp at a rated RPM of 1850, provides adequate power for moderate agricultural tasks or light industrial use. Its liquid-cooled, four-cylinder design ensures efficient thermal management, enhancing reliability during prolonged operation. However, with only 36.5 hp, it may face challenges in heavy-duty applications, such as plowing or heavy tilling, where higher horsepower tractors would be more suitable.

ATC 256 ENGINE
The ATC 256 tractor is powered by a Continental 2.3L 4-cylinder gasoline engine, offering a balance of power and efficiency suitable for light to medium agricultural tasks. Pros include potentially lower fuel consumption compared to diesel engines and reduced initial purchase costs, while challenges may arise in terms of lower torque output and reduced longevity compared to diesel counterparts. This setup is ideal for applications requiring moderate power with minimal operational complexity in urban or smaller scale farming environments.

TRANSMISSION
The ATC 256 tractor features a 3-speed forward and 1-speed reverse gear setup, providing simplicity and robustness for basic agricultural tasks. The dry disc clutch enhances durability and ease of maintenance; however, it may require more pedal effort compared to wet clutches. This tractor's gear configuration is ideal for light-duty operations but may limit speed variation for more complex tasks.

MECHANICAL
The ATC 256 tractor features a crawler chassis, providing excellent traction on uneven terrain but potentially limiting speed on flat surfaces. Its spur gear final drives improve durability and efficiency, while the contracting band brakes offer reliable stopping power, though they may require more maintenance than hydraulic systems. An open operator station enhances visibility and accessibility but exposes the operator to harsh weather conditions, making it ideal for short-duration tasks in mild environments.
