The new generation of the GRIMME's potato harvester EVO 280, which is well known for its high separation performance, enormous throughput and gentle crop handling is now equipped with a completely hydraulic drive-system. Additionally it comes with many innovations in terms of maintenance and user-friendliness.
Whether you want to harvest sensitive potato varieties at low speeds or need to handle large mass flows in an enriched harvesting process: Thanks to the completely hydraulic drive-system, all main webs, including the optionally available intake web, as well as the separators can be adjusted independently of the engine speed (PTO speed) of the tractor. 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 to the selected harvesting speed. The speeds of the second main web and deviner web can be set independently of each other with a differential speed of up to 30 %. If desired, electronic assistance systems like Speedtronic-Web and Speedtronic-Sep relieve the operator by automatically regulating all web speeds depending on the load. The operator can then easily concentrate on monitoring the machine thanks to the impressive size of the SmartView display. This new display also helps reduce fatigue when working long days.
For those who want to know exact the detail of the crop, GRIMME offers georeferenced mass (yield) mapping. This data can be accessed conveniently from home via the myGRIMME portal. An electronic link to the agrirouter for further transfer to all common farm management systems is also possible.

The optimisation of the intake design ensures reduced weight as well as improved contour adaptation, which prevents build-up and blockage by haulm. For improved crop protection against possible losses, the overlap between the first and second main web as well as between the second main web and the first separator has been increased. By optimising the positioning of the drive for the diviner web, it was possible to further increase both the pulling power and the stability. In combination with the newly positioned scraper comb, the tubers are separated from the haulm even more effectively. For maximum pushing power in difficult harvesting conditions, the new generation can also be equipped with a hydrostatic wheel drive.

The 8-tonne bunker is still fitted as standard. Alternatively, the machine can be equipped with the 7.5 t, patented NonstopBunker with a very large transfer distance. This makes it easy to unload during the harvesting process, even on platform trailers with 2 rows of boxes. The optional bunker web with canvas and all-round padding on the bunker bars ensures maximum crop protection. In addition, there is the optional lubrication system for the bunker chain, whereby oil is automatically applied to the chain links during the bunker unloading process.
In addition to the already familiar comfort packages for the picking table, the picking staff also benefit from a more attractive working environment thanks to extended comfort packages with additional cleaning spades, storage boxes and an aluminium ladder, as well as a re-designed canopy. The elimination of mechanical drive components also improves accessibility for cleaning and maintenance work, which is aided by the central lubrication points at various locations. For the coming year, a central lubrication system can also be selected as an option.
Thanks to the position lights fitted as standard, the machine contour is visible to the driver even in the dark. The new LED peripheral lighting ensures optimal illumination of the working environment.

At the Potato Europe, on 06 and 07 September 2023, the new generation of the EVO 280 will be demonstrated in the field.
