The launch of Cummins new F4.5 structural engine was bolstered by the Class Arion 4 Tractor of the Year victory.
Developed in collaboration over five years, the 4.5 litre, four-cylinder block is built over a cast iron block, oil pan and gear housing which make up part of the chassis for increased durability.
It’s a modification of the non-structural engine, and as such has many of the same advantages. It uses a common rail fuel injection system, and there is no exhaust gas recirculation. In fact the entire aftertreatment system has been redesigned to sit outside of the engine bay without impacting visibility. A Holset wastegate turbocharger is fitted.
Power outputs from the engine are between 130hp and 160hp, with torque levels reaching 646Nm, with 500Nm available at just over 700rpm for low-end pulling power. For ease of maintenance, engine intervals are 600hrs.
