De Watanabe <strong>BlackBird rotshark<\/strong> was ontworpen volgens deze logica. <strong>9,5 meter werkbreedte<\/strong> \u2014 het grootste in zijn klasse wereldwijd \u2014 het dekt tot <strong>2,38 hectare per productief uur<\/strong> bij een maximale werksnelheid van 2,5 km\/u.

Het is een gelede, getrokken machine die is ontworpen met de operationele realiteit van grootschalige steenruiming in gedachten. Het gelede frame maakt het mogelijk de machine in te klappen voor transport over landweggetjes zonder demontage, de trekhaak aan de achterzijde maakt directe koppeling met een THOR-steenbreker mogelijk voor continu harken en breken, en het constructiegewicht van 5300 kg zorgt ervoor dat de tanden over de volledige spanwijdte van 9,5 meter een constante grip op de grond hebben, zelfs op oneffen terrein in de bergen. Het resultaat is een machine die niet alleen doet wat kleinere steenharken doen, maar dan op grotere schaal. Hij maakt een andere aanpak mogelijk voor grootschalige steenruiming die met kleinere machines simpelweg niet haalbaar is.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-463\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-1.webp\" alt=\"Blackbird rotshark toepassing 1\" width=\"1496\" height=\"1051\" srcset=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-1.webp 1496w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-1-1280x899.webp 1280w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-1-980x688.webp 980w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-1-480x337.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1496px, 100vw\" \/><\/p>\n<p>De BlackBird maakt deel uit van de Watanabe <a style=\"color: #f07c00; text-decoration: none; font-weight: bold;\" href=\"https:\/\/rock-crusher-tractor.com\/nl\/\">productlijn voor landbeheer<\/a> Het is verkrijgbaar via Korea Watanabe Rock Crusher Tractor Co., Ltd. voor grote commerci\u00eble landbouwbedrijven, landaanwinningsbedrijven en landbouwontwikkelingsprojecten in heel Korea en de omliggende regio's.<\/p>\n<div style=\"background: #1a1a1a; color: #f5f5f5; border-radius: 6px; padding: 20px 24px; margin: 24px 0; box-sizing: border-box; border-left: 5px solid #f07c00;\">\n<p style=\"font-weight: bold; color: #f07c00; margin: 0 0 8px 0; font-size: clamp(14px,1.6vw+9px,16px);\">\u25b6 Voor wie is de BlackBird bedoeld?<\/p>\n<p style=\"margin: 0; color: #ccc; font-size: clamp(13px,1.4vw+8px,15px);\">The BlackBird is not a machine for the typical family potato farm or small mixed holding.

The tines \u2014 arranged across the full 9.5-meter working width in the pattern specific to the rock rake design \u2014 penetrate to a controlled shallow depth, gathering surface stones, boulders, and rock fragments from the soil as the machine advances. The PTO drive at 1000 RPM powers the tine agitation and separation action, helping lift and shed fine soil from the gathered stones as they accumulate and are directed toward the centre of the working width for windrow formation.<\/p>\n<p>The 5,300 Kg machine weight is not incidental \u2014 it provides the down-force that keeps the full 9.5-meter tine span in consistent ground contact across undulating or uneven highland terrain. A lighter machine of the same working width would &#8220;bridge&#8221; across ground hollows and miss surface stones in these zones; the BlackBird&#8217;s weight ensures the tines track the ground contour across the full width, even at the outer reaches of the 9.5-meter span where the tractor&#8217;s influence on frame depth is most indirect.<\/p>\n<h3>Het gelede frame \u2014 breed bereik, praktisch transport<\/h3>\n<p>A 9.5-meter wide implement in rigid form would be unmanageable on any public road and difficult to navigate even on wide farm tracks. The BlackBird&#8217;s articulated frame solves this: the outer sections of the frame fold inward for transport, reducing the machine&#8217;s road-transport width to dimensions compatible with farm track access. Folding and unfolding for field entry and exit is accomplished without disassembling the implement or detaching any components \u2014 the articulation joints are hydraulically actuated from the tractor cab.<\/p>\n<p>This transport capability is particularly relevant for Korean commercial farming operations where multiple fields in different locations need to be cleared in sequence. A machine that requires a specialist wide-load transport vehicle and road permit to move between fields would multiply the effective cost and complexity of a large-scale stone clearance program. The BlackBird&#8217;s fold-and-go articulation means it can be repositioned between adjacent fields or moved along farm tracks with the same tractor that operates it, without additional logistics.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-464\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Feature-1.webp\" alt=\"Blackbird Rock Rake Kenmerk 1\" width=\"1352\" height=\"1163\" srcset=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Feature-1.webp 1352w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Feature-1-1280x1101.webp 1280w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Feature-1-980x843.webp 980w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Feature-1-480x413.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1352px, 100vw\" \/><\/p>\n<h3>De achterste trekhaak \u2014 continu harken en verpletteren<\/h3>\n<p>The BlackBird&#8217;s most operationally distinctive feature is its rear hitch system, which allows a THOR stone crusher to be coupled directly behind the rock rake. In this configuration, the BlackBird passes across the field forming stone windrows, and the THOR crusher \u2014 trailing immediately behind on the same tractor movement \u2014 processes those windrows into crushed aggregate as the machine advances. The complete cycle of stone collection, windrow formation, and on-site crushing happens in a single coordinated pass, without a separate collection and crushing operation afterward.<\/p>\n<p>Deze combinatie van harken en verpulveren verandert de economische aspecten van grootschalige steenverwijdering op landbouwgrond drastisch. Zonder deze machine verloopt het proces als volgt: het veld harken (\u00e9\u00e9n tractorpassage) \u2192 de zwaden verzamelen met een shovel \u2192 transporteren naar een steenbreker of steenhoop \u2192 verpulveren of afvoeren. Met de BlackBird en THOR in combinatie: in \u00e9\u00e9n passage worden het veld geharkt, de zwaden verzameld en de stenen verpulverd. De verpulverde stenen blijven ter plaatse achter als grind dat in de bodem kan worden verwerkt of als oppervlaktemateriaal kan worden achtergelaten \u2013 waardoor de afvoerkosten volledig komen te vervallen.<\/p>\n<h3>Werksnelheid en dagelijkse productie<\/h3>\n<p>At maximum working speed (2.5 km\/h) with the full 9.5-meter width, the BlackBird&#8217;s theoretical coverage rate is 2.38 ha\/h. In practical Korean highland field operations \u2014 where field shapes, headland turns, stone density, and occasional stops for operator checks reduce productive time \u2014 a realistic daily output is 8\u201314 hectares per full working day, depending on field conditions and stone load. This compares to approximately 2\u20134 hectares per day for the EP-EW-4000 rock rake in equivalent conditions \u2014 the BlackBird achieves three to four times the daily area clearance output from the same labour investment.<\/p>\n<p>De snelheid moet worden afgestemd op de steendichtheid: zwaardere steenladingen vereisen een lagere werksnelheid om volledige grip van de tanden en ophoping van stenen mogelijk te maken; lichtere steenlagen kunnen met een hogere snelheid worden verwijderd zonder kwaliteitsverlies. De meeste Koreaanse hooglandontginningsbedrijven werken met een snelheid van 1,2\u20132,0 km\/u voor de eerste ontginning van bestaande steenvelden, waarbij hogere snelheden mogelijk zijn bij volgende passages of bij lichtere steenladingen.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-466\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-2.webp\" alt=\"Blackbird rotshark toepassing 2\" width=\"1496\" height=\"1051\" srcset=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-2.webp 1496w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-2-1280x899.webp 1280w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-2-980x688.webp 980w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-Application-2-480x337.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1496px, 100vw\" \/><\/p>\n<\/div>\n<p><!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 SECTION 4 \u2014 CORE ADVANTAGES \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"background: #fafafa; padding: 28px 3% 3%; border-radius: 6px; margin-top: 48px; box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(18px,2.5vw+10px,26px); background: linear-gradient(to right,#1a1a1a 0%,#2e2e2e 72%,#c86000 100%); color: #fff; padding: 14px 20px; border-radius: 4px; margin: 0 0 20px 0; line-height: 1.3;\">Waarom de merel de economie van grootschalige steenruiming verandert<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-465 aligncenter\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-1.webp\" alt=\"Blackbird Rotshark 1\" width=\"600\" height=\"600\" srcset=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-1.webp 600w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Blackbird-Rock-Rake-1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 600px, 100vw\" \/><\/p>\n<div style=\"display: flex; flex-wrap: wrap; gap: 14px; margin-bottom: 10px;\">\n<div style=\"flex: 1 1 240px; box-sizing: border-box; background: #fff; border: 1px solid #e8e8e8; border-top: 4px solid #f07c00; padding: 18px 20px; border-radius: 0 0 4px 4px;\">\n<p style=\"font-size: clamp(14px,1.6vw+9px,16px); font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">\u25a0 9.5 m \u2014 World&#8217;s Largest Class<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">Met een werkbreedte van 9,5 meter is de BlackBird wereldwijd de grootste steenhark in zijn categorie. Het voordeel van de werkbreedte ten opzichte van alle conventionele steenharken vertaalt zich direct in minder bewerkingen per veld, minder keren op de kopakker en lagere brandstof- en arbeidskosten per hectare. Voor bedrijven die honderden hectares per seizoen bewerken, spreekt de kostenberekening per hectare voor zich.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; box-sizing: border-box; background: #fff; border: 1px solid #e8e8e8; border-top: 4px solid #f07c00; padding: 18px 20px; border-radius: 0 0 4px 4px;\">\n<p style=\"font-size: clamp(14px,1.6vw+9px,16px); font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">\u25a0 Directe THOR-koppeling \u2014 Eentrapssysteem<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">The rear hitch enables the BlackBird to pull a THOR stone crusher in the same tractor pass \u2014 rake and crush simultaneously. This eliminates the separate collection and crushing cycle that adds a second machine and a second day&#8217;s work to conventional rake-then-crush operations. For land clearing contractors, this integration cuts the total machine-hours per hectare substantially.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; box-sizing: border-box; background: #fff; border: 1px solid #e8e8e8; border-top: 4px solid #f07c00; padding: 18px 20px; border-radius: 0 0 4px 4px;\">\n<p style=\"font-size: clamp(14px,1.6vw+9px,16px); font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">\u25a0 Gelede frame \u2014 Praktisch transport<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">A 9.5-meter machine needs to move between fields. The BlackBird&#8217;s hydraulically articulated frame folds to transport width without disassembly, allowing repositioning between fields along farm access tracks with the same operating tractor. No wide-load transport permit, no disassembly crew \u2014 the machine moves itself between clearing locations.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; box-sizing: border-box; background: #fff; border: 1px solid #e8e8e8; border-top: 4px solid #f07c00; padding: 18px 20px; border-radius: 0 0 4px 4px;\">\n<p style=\"font-size: clamp(14px,1.6vw+9px,16px); font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">\u25a0 5.300 kg \u2014 Volledig contact met de grond<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">The machine weight is distributed across the full 9.5-meter frame, ensuring all tines maintain consistent soil contact even on uneven highland terrain.

For a contractor clearing 200 hectares of new agricultural land, the difference between 0.5 ha\/h (conventional rake) and 2.38 ha\/h (BlackBird) is the difference between a 400-hour project and an 84-hour project \u2014 roughly a month of work versus two weeks.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 SECTION 5 \u2014 APPLICATION SCENARIOS \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"margin-top: 48px;\">\n<h2 style=\"font-size: clamp(18px,2.5vw+10px,26px); background: linear-gradient(to right,#1a1a1a 0%,#2e2e2e 72%,#c86000 100%); color: #fff; padding: 14px 20px; border-radius: 4px; margin: 0 0 20px 0; line-height: 1.3;\">Waar wordt de BlackBird Rock Rake voor gebruikt?<\/h2>\n<h3>\ud83c\udf3f Grootschalige opening van landbouwgrond in Korea<\/h3>\n<p>Korea&#8217;s highland agricultural zones \u2014 Gangwon-do in particular \u2014 have significant areas of potential agricultural land that remain uncultivated because surface stone density makes them impractical to work with standard farm machinery. These are typically former forest margins, abandoned pasture land, or areas that have accumulated surface stones through decades of frost-heave and water movement in the volcanic or granite-derived soils of the highland belt.<\/p>\n<p>Om dit land geschikt te maken voor de teelt van aardappelen, groenten of voedergewassen, is het noodzakelijk om de oppervlaktelaag van stenen te verwijderen tot een niveau waarop grondbewerkingsmachines, zaaimachines en oogstmachines kunnen werken zonder mechanische schade. De traditionele aanpak \u2013 handmatig stenen verzamelen of het gebruik van kleine steenruimers \u2013 is onacceptabel traag op percelen groter dan 10-20 hectare. De BlackBird verandert de schaal van wat praktisch haalbaar is: een perceel van 100 hectare kan in ongeveer 50 productieve machine-uren van stenen worden ontdaan, met een output van 2 ha\/uur. Dit maakt het economisch haalbaar om hooglandgrond te ontginnen voor commerci\u00eble bedrijven die met kleinere steenruimers simpelweg niet kunnen werken.<\/p>\n<h3>\ud83c\udfd9 Landaanwinning en landbouwinfrastructuurprojecten<\/h3>\n<p>De Koreaanse overheid neemt in haar landbouwinfrastructuurprogramma's \u2013 met name het programma voor de herwinning van landbouwgrond (\ub18d\uc9c0 \uac1c\ub7c9 \uc0ac\uc5c5) en initiatieven voor plattelandsontwikkeling in hooggelegen gemeenten \u2013 steevast het verwijderen van stenen als een verplichte voorbereidende stap voordat met bodemverbetering en cultivatie kan worden begonnen. Voor aannemers die inschrijven op deze overheidsprogramma's biedt de BlackBird een concurrentievoordeel, zowel qua prijs per hectare (lagere kosten per hectare dankzij een hogere doorvoer) als qua projectplanning (snellere oplevering binnen de contractuele termijnen).<\/p>\n<p>The Korean Ministry of Agriculture&#8217;s annual rural land development budgets fund tens of thousands of hectares of land improvement work across the country. Contractors equipped with large-capacity stone clearance equipment can bid competitively on the larger contract packages that single-machine small operators cannot efficiently serve.<\/p>\n<h3>\ud83c\udf33 Steenruiming voor aardappelproductiegebieden in de Hooglanden<\/h3>\n<p>De aardappelregio in de hooglanden van Gangwon-do \u2014 Pyeongchang-gun, Jeongseon-gun, Inje-gun en omliggende gemeenten \u2014 kent een aanzienlijk steengehalte in de van graniet en basalt afgeleide bodems. De steendichtheid is in veel velden zo hoog dat de <a style=\"color: #f07c00; text-decoration: none; font-weight: bold;\" href=\"https:\/\/rock-crusher-tractor.com\/nl\/product\/ep-ew-4000-rock-rake-3-6m-tractor-75hp\/\">EP-EW-4000 steenhark<\/a> (3,6 m) wordt door de meeste producenten gebruikt voor de eerste steenruiming in het voorjaar - een seizoensgebonden methode voor steenbeheer die in deze regio standaard is.<\/p>\n<p>Voor grotere commerci\u00eble aardappelbedrijven en co\u00f6peraties die meer dan 50 hectare beheren, is het uitvoeren van een voorjaarsruimbeurt met de EP-EW-4000 over het gehele teeltgebied een aanzienlijke tijdsinvestering die rechtstreeks concurreert met het plantschema. De BlackBird, met een werkbreedte van 9,5 meter, voltooit dezelfde voorjaarsruimbeurt in ongeveer 251 ton, waardoor de plantmachines volgens schema kunnen beginnen. Voor bedrijven die al tractoren van 300 pk of meer gebruiken voor andere doeleinden \u2013 grote rotorkultivatoren, getrokken oogstmachines of zware grondbewerkingsmachines \u2013 past de BlackBird binnen het bestaande machinepark zonder dat een aparte machine hoeft te worden aangeschaft.<\/p>\n<h3>\ud83c\udf3f Landconversie na bosbouw<\/h3>\n<p>In Korea is een programma gaande om marginale bosgrond om te zetten naar landbouwgrond, met name in gebieden waar voormalige plantagebossen worden afgebouwd en de grond wordt beoordeeld op alternatieve productieve benutting. Grond die na de bosbouw \u2013 nadat de bomen zijn gekapt en de stronken zijn verwijderd \u2013 ligt doorgaans bedekt met stenen, wortelresten en een ruwe ondergrond die moet worden ontdaan van obstakels en ge\u00ebgaliseerd voordat er standaard landbouwwerktuigen op kunnen worden gebruikt.<\/p>\n<p>The BlackBird&#8217;s combination of high working width, robust 5,300 Kg frame, and the option to trail the THOR stone crusher for in-situ processing of collected stones makes it well suited to this application.

Competitor machines in the rock rake category \u2014 such as the Schulte 2500 Giant or Degelman Rock King \u2014 have working widths of 1.5\u20132.4 meters. The BlackBird&#8217;s 9.5-meter span represents a fundamentally different design approach: an articulated multi-section frame rather than a single rigid beam. This articulation is what makes 9.5 meters practically achievable without requiring a road-legal wide-load transport for every field move.<\/p>\n<\/div>\n<div style=\"background: #fafafa; border-radius: 4px; padding: 16px 20px; border-left: 3px solid #ddd;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">Welk THOR-vergruizermodel is compatibel met de BlackBird-achterkoppeling?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">De <a style=\"color: #f07c00; text-decoration: none;\" href=\"https:\/\/rock-crusher-tractor.com\/nl\/product\/thor-3-0-rock-crusher-with-drawbar-kit-230-hp-heavy-duty-stone-crusher-for-tractor\/\">THOR 3.0 Steenbreker<\/a> (230 HP, drawbar Kit) is the primary coupling partner for the BlackBird in the Watanabe system.

The BlackBird alone \u2014 at 10.7 meters total width folded for transport \u2014 needs a headland of at least 15\u201318 meters to execute a clean field-end turn. With the THOR crusher coupled behind, the combined machine length is considerably greater and the headland requirement increases accordingly \u2014 approximately 25\u201330 meters. For Korean highland fields with limited headland space, confirm your headland dimensions when contacting us for a suitability assessment. Fields with less than 15 meters of headland may require the BlackBird to lift and reverse rather than turn, which slows the work pace but remains operationally feasible.<\/p>\n<\/div>\n<div style=\"background: #fafafa; border-radius: 4px; padding: 16px 20px; border-left: 3px solid #ddd;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">Kan de BlackBird zeer grote rotsblokken aan?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">Rock rakes are designed for surface stone clearance \u2014 stones and boulders that sit on or immediately below the soil surface. The BlackBird is not a rock crusher; it gathers and windrows material by tine engagement. For fields with large boulders (above approximately 40\u201350 cm diameter) embedded at the surface, a pre-clearance pass with the THOR 2.4 or THOR 3.0 to reduce boulders to a size the BlackBird can handle is recommended before the raking pass. We can advise on the appropriate field preparation sequence based on your field&#8217;s stone size description and a photograph of the surface conditions.<\/p>\n<\/div>\n<div style=\"background: #fff; border-radius: 4px; padding: 16px 20px; border-left: 3px solid #f07c00;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">Waarom heeft de BlackBird een aftakas met 1000 toeren per minuut nodig in plaats van 540 toeren per minuut?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">The 1000 RPM PTO standard is the conventional specification for high-power (300+ HP) agricultural tractors and heavy-duty implements. At 1000 RPM, more torque can be transmitted through a shaft of the same diameter than at 540 RPM, allowing the BlackBird&#8217;s 5,300 Kg implement to receive sufficient drive power for the tine agitation and separation mechanism across the full 9.5-meter working width. The 540 RPM PTO standard \u2014 used by all Watanabe potato machinery and the DESTROYER compost barn aerator \u2014 is the appropriate specification for 75\u2013200 HP implement applications. For a 5,300 Kg implement driven by a 300 HP tractor, 1000 RPM is the correct engineering specification. Large Korean agricultural tractors in the 300+ HP class all provide 1000 RPM PTO as standard; verify this on your specific tractor&#8217;s specification sheet before ordering.<\/p>\n<\/div>\n<div style=\"background: #fafafa; border-radius: 4px; padding: 16px 20px; border-left: 3px solid #ddd;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">Wat moet ik doen met de steenhopen na de BlackBird-pas?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">Three main options: (1) Crush in place using the THOR crusher coupled to the BlackBird&#8217;s rear hitch \u2014 the crushed aggregate remains on the field as granular material that is tilled in or left as surface gravel; (2) Collect with the <a style=\"color: #f07c00; text-decoration: none;\" href=\"https:\/\/rock-crusher-tractor.com\/nl\/product\/ct-2100-rock-picker-110-hp-professional-stone-collector-with-2-5-m\u00b3-bunker-korea-stock\/\">CT-2100 Steenrapper<\/a> and transport to a defined disposal or use point \u2014 the CT-2100&#8217;s 2.5 m\u00b3 bunker allows efficient collection of the windrows without manual handling; (3) Push the windrows to the field margin using a front loader and construct a permanent stone boundary. The appropriate approach depends on the volume of stone collected and whether there is a productive use for the material.<\/p>\n<\/div>\n<div style=\"background: #fff; border-radius: 4px; padding: 16px 20px; border-left: 3px solid #f07c00;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0;\">Is de BlackBird geschikt voor de hellingen van het Koreaanse hoogland?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">The BlackBird&#8217;s 5,300 Kg weight and 10.7-meter total width make it more suited to open, relatively flat agricultural land rather than the steeply terraced highland plots where the compact EP-EW-4000 rock rake is the appropriate tool. For moderate gradients up to approximately 10% (1:10) on open highland fields with adequate headlands, the BlackBird is practical. On steeper slopes or narrow terraced land, the EP-EW-4000 at 3.6-meter working width and Cat.2 hitch mounting is the safer and more maneuverable choice. If your primary production area includes both open flat land and terraced hillside plots, a combined approach \u2014 BlackBird for the open areas and EP-EW-4000 for the terraced sections \u2014 may be the optimal configuration.

De exacte transportbreedte dient u met ons te overleggen voor de huidige productieconfiguratie. Voor toegang over Koreaanse landbouwpaden zijn de ingeklapte machinebreedte en de gecombineerde totale lengte van tractor + BlackBird de belangrijkste afmetingen. Over het algemeen is de BlackBird in ingeklapte transportpositie geschikt voor Koreaanse hooglandwegen met een breedte van 3,5 tot 4,0 meter; smallere toegangswegen vereisen mogelijk het vrijmaken of verbreden van de weg voordat de machine naar het veld kan worden vervoerd. Geef bij uw aanvraag de breedte van uw landbouwpad en eventuele poorten of bruggen met beperkte breedte door, zodat wij de geschiktheid kunnen beoordelen.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 SECTION 10 \u2014 CUSTOMER REVIEWS \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"margin-top: 48px;\">\n<h2 style=\"font-size: clamp(18px,2.5vw+10px,26px); background: linear-gradient(to right,#1a1a1a 0%,#2e2e2e 72%,#c86000 100%); color: #fff; padding: 14px 20px; border-radius: 4px; margin: 0 0 20px 0; line-height: 1.3;\">Wat onze klanten zeggen<\/h2>\n<div style=\"display: flex; flex-direction: column; gap: 16px;\">\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 20px; background: #fff;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Jeong Kwang-il \u2014 Aannemer voor de ontwikkeling van landbouwgrond, Gangwon-do (2024)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 12px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;We contracted to clear and prepare 180 hectares of former marginal forest land in Gangwon-do for conversion to potato production \u2014 a large government-backed rural development project. Running the BlackBird with the THOR 3.0 coupled on the rear hitch, we cleared the surface stone load across the full 180 hectares in 19 working days. Our previous estimate for the same area using conventional equipment was 60 working days. The rake-and-crush single-pass combination was the key \u2014 no separate collection operation, no stone disposal. The project came in under budget and the delivery date was met comfortably.&#8221;<\/p>\n<\/div>\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 20px; background: #fafafa;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Oh Byeong-chul \u2014 Groot commercieel landbouwbedrijf (hooglandaardappelen, 120 ha), Pyeongchang-gun (2024\u20132025)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 12px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;We run a spring stone clearance pass across our 120-hectare potato production area every year before tillage and planting. With the EP-EW-4000 we were using before, this took about 12 working days with two tractors. The BlackBird does the same area in 4 days on one 330 HP John Deere. The tractor already owned the HP for other heavy operations \u2014 the BlackBird just added the width capability we were missing. Time saved on stone clearance went directly into earlier planting, which gave us a longer growing season on the later-maturing blocks. Good investment.&#8221;<\/p>\n<\/div>\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 20px; background: #fff;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Han Jae-su \u2014 Aannemer van landbouwmachines (diensten voor het verwijderen van stenen), regio Wonju (2025)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 12px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;I run contract stone clearance services for about 12 farms in the Wonju and Hoengseong area \u2014 total contract area is around 250 hectares per spring season. The BlackBird is the machine that made this contract volume possible. At 2+ ha\/h effective output, I can service the full 250-hectare contract area in approximately 20 working days. The same volume with conventional rock rakes would need three machines and three operators.

The BlackBird was specified for the project after the Korea Watanabe team assessed our field dimensions and confirmed the headland space was adequate. Total stone clearance time: 9 working days across all three farms. The articulated frame&#8217;s transport folding capability was critical \u2014 we moved the machine between the three different farms along rural farm tracks without any access issues. The stone windrows were then collected using the CT-2100 rock picker and used for track surface improvement on the same farms.&#8221;<\/p>\n<\/div>\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 20px; background: #fff;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Kwon Seok-jin \u2014 Project voor de uitbreiding van de boerderij, Inje-gun, Gangwon-do (voorjaar 2025)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 12px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;We purchased 40 hectares of former marginal grazing land adjacent to our existing potato farm and needed to prepare it for cultivation in a single spring season. The land had significant surface stone accumulation from decades of natural frost-heave \u2014 an estimated 400 tonnes of surface stone per hectare in the worst sections. The Korea Watanabe team recommended a two-pass approach: THOR 2.4 pre-crush on the heaviest sections first, then BlackBird across the full area. Following the recommended sequence, we had the full 40 hectares cleared, stone-free, and ready for the rotavator within 11 working days.

We ran the BlackBird with THOR 3.0 on the rear hitch across the full area \u2014 two passes on the heaviest sections, one pass on the lighter areas. The crushed aggregate from the combined operation improved the surface drainage characteristics of the former forest soil. The area was seeded with forage in the first year and will transition to vegetable production next season.&#8221;<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 CONTACT CTA \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"background: #1a1a1a; color: #fff; padding: 3%; border-radius: 6px; margin-top: 52px; text-align: center; box-sizing: border-box;\">\n<p style=\"font-size: clamp(17px,2.2vw+9px,24px); font-weight: bold; margin: 0 0 12px 0; color: #f07c00;\">Meer land vrijmaken.
