Following on from presenting the F4.5 Structural engine as a prototype at EIMA 2024, Cummins has unveiled the production-ready version of the same engine at this year’s EIMA trade fair in Bologna, Italy.

The 4.5-liter four-cylinder turbodiesel engine can produce between 96 and 118 kw, dependent on configuration. Maximum torque is 646 Nm.

As the name suggests, the F4.5 Structural is intended to act as a critical component within the tractor chassis. The cylinder block, oil pan and gear housing are all made of cast iron to add strength to the engine.

Other key features include a Holset wastegate turbocharger and a Flex Module emissions aftertreatment system (EATS), each produced in-house by Cummins. The EATS combines DPF and SCR systems, but the unit does not use an EGR. The engine is Stage 5 emissions compliant.

A high-pressure common rail injection system delivers precise combustion for improved fuel efficiency and lower fuel costs. Service intervals are set for 600 hours.

The Connected Diagnostics system can monitor engine health, while offering predictive maintenance insights to extend uptime. This includes notifying of a situation where the engine may derate and offering a potential solution.

The F4.5 Structural was developed with assistance from tractor OEM Claas. It will feature in the new Claas Arion 4, which was recognized as Tractor of the Year – Utility at EIMA 2026.
