Nexat

Nexat (stylised NEXAT) is a German manufacturer of agricultural machinery for crop production, headquartered in Rieste in Lower Saxony. The name is an acronym for "Next Generation Agriculture Technologie" (Next Generation Agricultural Technology). The company was founded in 2017 by Felix and Klemens Kalverkamp and is dedicated exclusively to the development, manufacture and sale of a new plant production system. Klemens Kalverkamp had previously served as head of development and managing director at leading agricultural machinery manufacturers, giving the young company deep experience in product development. The firm reports a team of around 150 employees at its main site in Rieste. NEXAT's core offering is a modular carrier vehicle — the NEXAT system tractor — that carries rather than pulls implements, combining all steps of crop production from soil tillage to harvest in a single machine. The system operates on the "Widespan Controlled Traffic Farming" (WS-CTF) principle: permanent, offline-planned tramlines 14 metres wide are used year-round, and the NEXAT drives these tracks autonomously. Depending on the module, working widths of up to 70 metres are possible, and the company claims that up to 95% of the field area is never driven over during tillage. The system tractor uses electric individual wheel drives powered by generators run by two 550 hp diesel engines; wheels can turn 90° for road travel and the cab rotates 180° to suit the mounted module. Key products include the NEXAT system tractor, the Nexco threshing/harvest module and the Seedhopper tank system. The Nexco harvest module splits the crop into two even streams transverse to the direction of travel and has two cleaning systems and two straw choppers for even straw distribution across 14 metres. The Seedhopper tank system forms the interface between tillage and seeding modules and the carrier vehicle, with four tank units for liquid and solid inputs and a central seed inlet, allowing three products to be applied simultaneously with weight recorded by load cells. Further modules developed with partner manufacturers include headers (draper, picker, sunflower), a short disc harrow, a precision seeder, a drill, two crop protection modules and a slurry module. The company has received recognition at Agritechnica: a Gold Medal from the German Agricultural Society (DLG) in 2022 for the NEXAT system tractor, and the DLG agrifuture concept winner award in 2023. NEXAT positions its system as the most profitable plant production system, emphasising lower investment costs, reduced fuel consumption, less labour requirement and minimal soil compaction, while supporting long-term sustainability. The system has already been in use on selected farms under real conditions for several years.

Nexat GmbH was founded in 2017 by Felix and Klemens Kalverkamp. The new company was dedicated exclusively to the development, manufacture and sale of a new plant production process. Klemens Kalverkamp had previously worked for many years as head of development and managing director at leading agricultural machinery manufacturers, giving the company extensive experience in product development. Numerous patents and awards attest to the innovative strength of the entrepreneurial family, which with NEXAT has produced a groundbreaking highlight of agricultural engineering development. The main location is Rieste in Lower Saxony, which also serves as the production site. The company reports a team of around 150 employees. The NEXAT system is not merely a vision: the new plant production system has already been in use on selected farms under real conditions for several years, reportedly with great success. The company frames its work around the challenges of agriculture, including climate change, food security for a projected 10 billion people, and massive loss of arable land. The system works on the "Widespan Controlled Traffic Farming" (WS-CTF) principle, which aims to establish permanent tramlines for all arable farming operations year-round in order to avoid permanent soil compaction of the growing areas. The tramlines are planned once offline, and the NEXAT drives them autonomously. The track width is 14 metres, and depending on the module a working width of up to 70 metres is possible. The large track width means that up to 95% of the arable land is never driven over during tillage. The various modules are carried by the NEXAT system tractor rather than pulled, which according to the manufacturer enables precise guidance of the implements and shifts the weight of the modules onto the driven axles. The system tractor drives with electric individual wheel drives. The generators for the drive are powered by two 550 hp diesel engines. The wheels can be swivelled by 90° for road travel, and the cab by 180° to adapt the view to the modules. The Nexco harvest module divides the crop into two even streams transverse to the direction of travel; the threshing module has two cleaning systems and two straw choppers, which is intended to achieve even straw distribution over 14 metres. The Seedhopper tank system forms the interface between the planned tillage and seeding modules and the system tractor. It comprises four tank units for liquid and solid materials and a central inlet for seed, so that three products can be applied simultaneously. The weight of the individual products is recorded via load cells. Further modules have been developed in cooperation with other agricultural machinery manufacturers and are connected to the carrier vehicle via a standardised interface. As of 2023 these included headers (draper, picker, sunflower), a short disc harrow, a precision seeder, a drill, two crop protection modules and a slurry module. At Agritechnica 2022, Nexat GmbH was awarded a Gold Medal by the German Agricultural Society (DLG) for the NEXAT system tractor. In 2023, the company received the DLG agrifuture concept winner award at Agritechnica.
