ENGINE DETAIL
The Fiat-Hesston 45-66 features a 2.7 L diesel engine with a notable 17:1 compression ratio, providing efficient combustion and improved torque at lower RPMs, ideal for agricultural applications. Its 45 hp output at 2500 RPM allows for moderate power delivery, making it suitable for tasks such as plowing and haymaking in small to mid-sized fields. However, the 3-cylinder design may result in less smooth operation compared to 4-cylinder engines, potentially impacting performance in heavy-duty tasks.
