HESSTON 45-66 ENGINE
The Hesston 45-66 tractor is powered by a Fiat 2.7L 3-cylinder diesel engine, which offers a balance of fuel efficiency and adequate torque for light to medium-duty tasks. Its fuel capacity of 11.1 gallons (42.0 liters) allows for extended operational time, reducing downtime for refueling in agricultural settings. However, the relatively small engine size may limit its performance in heavy-duty applications, making it less suitable for large-scale farming operations.
