Dewulf introduces the 3rd generation of the Kwatro and Kwatro Xtreme 4-row self-propelled potato and root crop harvester on tracks. 16 years after its introduction, the renewed Kwatro (Xtreme) builds on the foundation of previous generations, but offers more bunker capacity, ease of use and protection of the harvested product.
The technology that was already available on the Enduro, 4-row self-propelled sieving harvester on wheels, is now also available on the Kwatro. With Level X Gold, the harvester actively makes decisions based on sensors, data and AI-driven analysis. As a result, constant quality can be guaranteed, regardless of who is behind the wheel, and harvesting can also be done at more than 2 km/h faster. More output with the same input.
In addition, the packages Level X Silver (option) and Level X Bronze (standard) are also available. With Level X Silver, a camera system enables to further personalize settings, have remote view, slow motion and casting integration with a smartphone and navigation on the road. With Level X Bronze, growers gain valuable insights via the integrated IoT platform.
The 3rd generation comes in 4 variants, allowing the harvester to serve everyone’s needs.
1 Kwatro
Variant equipped with 3 sieving webs, hedgehog belt and Flexyclean 2.0 module. This module is a further developed patented bypass system in combination with axial rollers, allowing perfect adaptation to harvesting conditions. The degree to which the potatoes are cleaned can be continuously adjusted from 0 to 100% from the cab.
2 Kwatro Xtreme
Variant for row spacings bigger than 80 cm, equipped with 3 sieving webs, hedgehog belt and Flexyclean 2.0 module. The harvester is characterized by a full sieving path, without restrictions, resulting in maximum cleaning capacity and product friendliness. The Kwatro Xtreme therefore has a width of 4.10 meters.
3 Kwatro Xtreme Flow with double Easyclean
The Flow version of the Kwatro Xtreme is a variant for row spacings of over 80 cm and without hedgehog belt. The first 2 sieving webs are identical to the Kwatro Xtreme, followed by a 3rd short sieving web and a double, Quick-Change, Easyclean module. This module consists of 7 (4+3) active, smooth cleaning rollers alternated with 9 Easyclean rollers. The unit is divided into 2 groups of respectively 4 and 3 linked, active, smooth cleaning rollers. This offers the operator the possibility to determine the speed, height, opening and direction of rotation of the active cleaning rollers of both groups separately. Thanks to the new Quick-Change system, Easyclean segment axles can now be replaced easily and quickly (bearings no longer need to be dismantled). Think for example of changing harvesting conditions where different segments are required. In addition, the module can be set between 0- and 12-degrees inclination, making the level of cleaning extremely flexible to adjust.
4 Kwatro Xtreme Flow with axial rollers and Easyclean
This variant is for row spacings greater than 80 cm and without hedgehog belt, where the cleaning unit is a combination of 36 axial rollers and a single Easyclean module. The Easyclean module consists of 2 active, smooth cleaning rollers alternated with 3 Easyclean rollers. The module can also be set between 0- and 12-degrees inclination.
18 m³ large bunker
The Kwatro (Xtreme) now comes standard with a 2-part, 18 m³ large bunker with discharge elevator, making it the largest and most product-friendly in its segment. Unloading is extra product-friendly as there is no transfer roller and no cover so the product doesn’t need to pass through a funnel. Because the fixed bunker floor is followed by a discharge elevator with bar webs, excess soil is sieved out during unloading.
With 10% extra power compared to the previous generation, the new Kwatro (Xtreme) features a Scania DC13 Stage V engine, delivering 550 hp, with extended cooling to handle the most extreme weather conditions.
Comfortable working environment
The spacious Claas X-11 cab offers a pleasant working environment. The upgraded Premium cab features a leather seat with seat ventilation, refrigerator, additional windscreen wipers and sun curtains.
Thanks to the ergonomically designed ‘N-joystick’, the operators’ hand rests in a comfortable horizontal position and long harvesting days feel much easier. Moreover, all buttons are within ‘thumb reach’, allowing every important function to be always operated without moving the hand. The large clear control unit is fully touchscreen. The software was specially developed in-house and builds on the user-friendly interface.
Proven technologies retained
Frontal harvesting in combination with 90 cm wide tracks and a wide rear wheel (1250/50 R32) guarantee harvesting in all conditions with minimal ground pressure.
Thanks to this setup (tracks left/right and rear wheel in the middle), the field remains level after harvesting. By maintaining the full width of the sieving path, the risk of blockages is minimized. Various harvesting kits make the harvester flexible to harvest different vegetable crops such as potatoes, industrial carrots, onions and chicory roots.
