Claas tests partially electric propulsion for Lexion combines

Claas emphasizes that this new development will not be available for purchase in the next three to five years. However, they do mention that they are working on a Lexion e-hybrid, which is a partially electric propulsion system for combines. For this innovation, Claas has been nominated for the DLG Agrifuture Concept Winner 2023 award, with the award ceremony taking place in November at the Agritechnica trade fair.

Stable engine load

The concept behind the Lexion e-hybrid is to maintain a more constant engine speed during the harvesting process, even with varying engine loads. To achieve this, Claas adds a generator, a battery, and an electric motor to the drivetrain. The battery is continuously charged, and when the engine load increases, the electric motor provides brief assistance. This, according to the manufacturer, results in less fluctuation in engine speed. Claas’ tests have shown that this approach can lead to a fuel savings of 8 to 10%.
