At the Agritechnica 2013, GRIMME and SPUDNIK, which is also part of the GRIMME Group, presented the AirSep separator, which was awarded the highest award of the German Agricultural Society (DLG) - a DLG Gold medal. This separator, which is particularly suitable for stony soils, has undergone extensive further development in recent years and has been integrated into an independent new machine series - called AIRSEP 290. Numerous changes, such as the modified crop flow and the optimised installation position of the AirSep blower, significantly increase reliability and stability.

The AIRSEP 290 is equipped with a fully hydraulic drive. This means that all main webs, including the optionally available intake web and the separators, can be adjusted independently of the engine speed (PTO speed) of the tractor.
The avoidance of mechanical drive components also improves accessibility for cleaning and maintenance work. The speeds of all main webs, including the deviner web, are now displayed in km/h, making it easier for the driver to adjust the web speeds in relation to the forward speed of the tractor. The speeds of the second main web and deviner web can be set independently of each other. If desired, electronic assistance systems like Speedtronic-Web and Speedtronic-Sep relieve the operator by automatically regulating all web speeds.
The optimisation of the intake design ensures reduced weight as well as improved adaptation to the ground contour, which prevents build-up and blockage by haulm. For improved crop protection and reduction of possible losses, the overlap between the first and second main web has been increased. The optimised placement of the drive for the deviner web has increased both pulling power and durability. The centrally installed lubrication rails for the bunker and axle make it much easier and faster to maintain the machine. An automatic lubrication system is also available as an option. The boulder box was also enlarged to a capacity of around 1 m³.

More space and comfort for picking staff
Further improvements have been made to increase convenience for the picking staff . The platform on the left-hand side of the machine can be extended so that up to 5 people can work comfortably at the picking table. Height-adjustable steps are also available, which allow the picking staff to work at a comfortable height. Also available are a waterproof storage box, stuffing on the picking table, drink holders and a 15-litre hand wash tank.
Overall, the above-mentioned upgrades have significantly improved the reliability and stability of the machine, meaning that series production of the AIRSEP 290 will begin in 2024 with its new, functional design.

Christine and Franz Grimme received a special honour on 11 September 2024 at the BayArena in Leverkusen as part of the Agricultural Trade Forum.
GRIMME presents the revised BF and BFL series bed formers for the 1-, 2- or 3-bed system.
For the 2025 season, GRIMME is introducing the new PRIOS 440 cup planter as a version for growing potatoes in (separated) beds.
The new ‘Fields’ and ‘Crops’ applications are now available to users of the myGRIMME end customer portal.
