ENGINE DETAIL
The Challenger 65C features a robust Caterpillar 3306 DITA turbocharged diesel engine with a displacement of 10.5 L, delivering 285 hp at 2100 RPM, making it suitable for heavy agricultural work. Its liquid-cooled inline configuration and high compression ratio of 15:1 enhance thermal efficiency, but the weight and complexity of the engine may pose maintenance challenges. This model benefits from a direct injection fuel system for improved combustion, while the dual dry air cleaner and ether injection pre-heating ensure reliable performance in varied operational conditions.

TRANSMISSION
The Challenger 65C tractor features a full power shift transmission with 10 forward and 2 reverse gears, providing efficient power transfer and smoother operation during field work. Its oil capacity of 60 quarts (56.8 liters) allows for extended operating periods between changes, enhancing maintenance intervals. However, the reliance on a full power shift may pose challenges in complex terrain, requiring more operator skill to maximize the tractor's capabilities.

MECHANICAL
The Challenger 65C tractor features a crawler chassis that provides enhanced stability and traction on uneven terrain, making it ideal for agricultural applications in challenging conditions. Its hydraulic wet disc braking system offers superior stopping power and longevity compared to traditional braking systems, while the 10-speed full power shift transmission allows for smooth and efficient gear shifting, optimizing performance under heavy loads. However, the crawler setup may limit speed on paved surfaces, which is a consideration for operations that involve transport on highways.
