ENGINE DETAIL
The AGCO ST40 is powered by a 1.5L Iseki turbocharged diesel engine, delivering 40hp (29.8kW) at a rated RPM of 2600, which offers excellent torque characteristics for enhanced performance in fieldwork. Its indirect injection fuel system provides better fuel atomization, leading to improved combustion efficiency, while the compact 3-cylinder configuration optimizes engine weight for agile maneuverability. However, the limited power output may restrict its capability for heavy-duty tasks, making it ideal for lighter agricultural applications or small farm operations.
