ENGINE DETAIL
The Challenger 65B tractor features a powerful 6-cylinder, turbocharged diesel engine with a substantial displacement of 10.5 L, providing 285 hp at 2100 RPM. Its dual dry air cleaner enhances airflow efficiency, contributing to excellent performance and fuel efficiency, while the 15:1 compression ratio allows for improved torque output, particularly beneficial in heavy-duty applications. However, the relatively high coolant capacity of 44 quarts indicates potential challenges in managing thermal efficiency, especially when operating in extreme conditions.
