Bosch Rexroth has supplied electrification components for an innovative prototype of a universal, multi-purpose agricultural vehicle (Autonomous Process Unit), developed by KRONE and LEMKEN. In pursuit of autonomous and economical operation, the two agricultural machinery manufacturers are integrating the robust and highly efficient eLION modular electrification platform components into their diesel-electric drive systems.
This multifunctional vehicle has attracted considerable interest and has successfully undergone testing as a future agricultural tractor for established work processes. As it can be used for various purposes such as soil cultivation, seedbed preparation, weeding, mowing, turning and raking, the autonomous machine can be used all year round. Thanks to the autonomous system, KRONE and LEMKEN can offer a forward-looking solution to the impending shortage of skilled workers in the industry.
Rather than spending long days working in the field, farmers can focus on operating this autonomous vehicle’s system, ensuring high-quality, precise work.
KRONE and LEMKEN have presented the ‘Combined Forces’ project, which differs from other autonomous vehicles in that it has been comprehensively developed based on the work processes of the machine.

This universal autonomous agricultural vehicle is one of many pilot applications using the scalable eLION electrification solution, which offers high-voltage components for driving and work processes, and eLION electric motors can also be used in generator mode. The modular platform includes inverters, gearboxes, customised hydraulics and software, as well as on-board chargers and DC-DC converters. All inverters have fully integrated functional safety features in accordance with ISO 13849, reducing engineering time.
