2021 Grimme WR 200 CHE

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.

The mechanical ridge relief minimises clodding in heavy soils and thus ensures improved crop protection. In sandy soils the crop flow is also improved because the ridges will not fall apart.

The axle steering improves agility and correction at slopes. In addition, the wheels can be moved to the centre position at the push of a button using the axle self-centre steering, further enhancing the driver's operating comfort.

The main web angle can be adjusted via hydraulic cylinders to adapt to a wide range of harvesting conditions. This not only increases ground clearance but also achieves an optimum compromise between sieving performance and crop protection.

The combination of a rocker agitator (option) with a rotary agitator ensure additional, gentle sieving on the first main web.

Features may include:

• Easy to pull but strong machine starting at 47 HP tractor power

• For row widths of 75 and 90 cm

• As standard with four spring loaded disc coulters and two diablo rollers for accurate depth control of the ridge intake.

• The drive and the digging units are taken from proven 2-row harvester technology

• Reliability and low maintenance also with high output

• A load-sensing kit to reduce oil heating and energy input is available

• A bed level adjuster and a following bed roller ensure an even and slightly compacted surface, the harvested crop stays on the surface for better drying.

• With its long, continuously from the front to the back running main web, and a central, superficial deposit of the harvested tubers and no specific haulm separation, the machine is perfectly suitable for the entry into mechanised potato harvesting.

• Suitable for two-phase (delayed, discontinous) harvest process

• A bed level adjuster and a following bed roller ensure an even and slightly compacted surface, the harvested crop stays on the surface for better drying.
