Potatoes and other root crops are harvested worldwide using various methods and degrees of mechanisation. With the windrower type WR 200, GRIMME offers a trailed harvester, which has been designed for various applications, using the well proven digging units from the 2-row harvesting technology of the SE series. Thanks to its easy handling and the minimum required tractor power of 47 hp, the modular designed harvester is the perfect machine to start mechanised harvest of potatoes and other root crops. Depending on the machine-model, the crop is deposited centrally or laterally behind the machine. Configured as a machine with centre deposit, the potatoes can either be collected by hand or picked up in a two-phase harvesting process after drying with a windrow intake. The reduced amount of adherent soil improves the suitability for long-term storage of the potatoes and results in a significant increase in performance of the following harvester. Equipped with a crop cross conveyor the harvester WR 200 can also be used in enhanced harvesting processes. In this case, the crop from two rows is deposited laterally between the next two neighbouring rows and then harvested together. In addition to protecting the crop and improving sieving performance, the "enhanced harvesting process" also significantly increases the output of the following potato harvester.
