ENGINES OVERVIEW
The ATC 656 tractor is powered by a choice between a Continental 3.4L 6-cylinder gasoline engine or a diesel variant, offering flexibility depending on fuel preference and application needs. The gasoline engine typically provides higher RPM and quicker responsiveness, while the diesel option delivers better torque and fuel efficiency, making it suitable for heavy-duty tasks. Consider your operational scenarios: if quick tasks with lighter loads are common, the gasoline engine may suffice; for prolonged, heavy-duty use, the diesel configuration is advantageous.

ENGINE DETAIL 1
The ATC 656 tractor features a robust Continental F-209 6-cylinder gasoline engine with a displacement of 3.4 L and a gross power output of 62 hp at 2250 RPM, providing strong torque performance of 164 lb-ft at 1200 RPM. Its liquid-cooled system, along with 5 quarts of oil and 16 quarts of coolant capacity, facilitates optimal thermal management, essential for extended operation in demanding conditions. However, the reliance on gasoline may limit efficiency compared to diesel counterparts, particularly in heavy-duty applications where fuel economy is paramount.

ENGINE DETAIL 2
The ATC 656 tractor, powered by the Continental ED-208 diesel engine, features a 3.4 L displacement delivering 62 hp at 2250 RPM and a robust torque of 155 lb-ft at 1400 RPM, which is ideal for medium-duty applications like tillage and hauling. Its 12-volt electric starter enhances reliability during operation, while the 7-quart oil capacity ensures adequate lubrication, reducing wear in demanding scenarios. However, potential challenges include its moderate power output compared to modern tractors, which may limit its use in heavier tasks.
