Cummins F4.5 Structural engine debuts in first tractor application
Purpose-built engine integrated into new CLAAS ARION 4 CMATIC tractor following five-year development program
COLUMBUS, IND. — Cummins Inc. (NYSE: CMI) marked a significant milestone in its agricultural engine portfolio, with the introduction of the F4.5 Structural engine in the new CLAAS ARION 4 CMATIC tractor at EIMA International in Bologna, Italy. The debut is the culmination of a five-year development program, bringing Cummins’ engineering expertise and purpose-built structural engine technology to a new generation of agricultural machinery.
The F4.5 Structural was engineered around the structural, packaging and performance requirements of modern tractors. Unlike a conventionally mounted engine, its cast-iron block, oil pan and gear housing form part of the tractor chassis, helping increase strength and durability while reducing overall machine weight. Field testing validated its performance across demanding agricultural tasks, including ploughing, field preparation, manure spreading and bale handling.
The engine delivers a maximum power range of 96-118 kW (130-160 hp) with peak torque of 646 Nm (476 lb-ft), with the specific rating dependent on the tractor configuration. Its compact four-cylinder architecture combines high power density with a steep low-end torque rise designed to help prevent stalling during demanding field work.
“The introduction of the F4.5 Structural in the CLAAS ARION 4 CMATIC marks an important step in our commitment to agriculture customers and delivering solutions to meet their needs,” said Marina Savelli, Vice President - Cummins Engine Business Off Highway Markets. “This highly integrated solution brings together the performance, durability and reliability required for demanding agricultural applications. It reflects our continued focus to helping equipment manufacturers deliver the productivity farmers depend on season after season.”
Beyond its structural design, the F4.5 is engineered to deliver responsive performance across the changing loads farmers encounter in field and farm operations. The engine uses a common-rail fuel system for precise combustion and fuel efficiency and offers oil drain intervals of up to 600 hours under stated maintenance conditions. Service points are designed for easy access, helping reduce routine maintenance time during busy agricultural seasons. The Stage V-certified F4.5 uses a single electronic control module for the engine and aftertreatment and does not use cooled exhaust gas recirculation, reducing the number of components and the potential for service events.
Purpose-built for the tractor
Structural integration allows the engine to serve as an integral link between major tractor components. In addition to reducing parts complexity and overall machine weight, the narrow engine profile creates additional space for front-wheel articulation. Focusing on customer satisfaction, this design enabled CLAAS to develop a slope nose for optimized visibility and a slimmer oil sump for maximum maneuverability.
For equipment manufacturers, the compact, higher-power-density design also provides greater flexibility when optimizing overall machine architecture. The engine will be manufactured at Cummins’ Darlington Engine Plant in the United Kingdom.
Bringing performance and power together with Cummins and CLAAS
The introduction of the F4.5 Structural in the ARION 4 CMATIC represents an important milestone in the relationship between Cummins and CLAAS, bringing Cummins engine technology into the new tractor platform.
“The new ARION 4 CMATIC reflects the strength of our collaboration with Cummins,” said Dr. Martin von Hoyningen-Huene, Chief Technology Officer (CTO), CLAAS Group. “Cummins brought deep engine expertise and a strong understanding of agricultural applications to the development process. Together, we have integrated the F4.5 Structural engine into a tractor designed to deliver the compact performance, durability and efficiency our customers expect.”
The introduction of the F4.5 Structural in the CLAAS ARION 4 CMATIC builds on Cummins’ experience in agricultural power and continued investment in solutions for equipment manufacturers. It also reflects the strength of Cummins' engineering expertise, manufacturing and global support capabilities to meet the evolving demands of modern agriculture.
EIMA attendees can see the F4.5 Structural in Hall 15, Stand A3 as part of Cummins’ agricultural power portfolio display.
