The World’s Largest Rock Rake \u2014 9.5 Meters of Ground-Clearing Width<\/h2>\n

Le d\u00e9frichement \u00e0 grande \u00e9chelle \u2014 ouverture de nouvelles terres agricoles, remise en \u00e9tat de champs abandonn\u00e9s envahis par les pierres de surface, pr\u00e9paration des terrains montagneux en vue de leur am\u00e9nagement \u2014 est une op\u00e9ration o\u00f9 la largeur de la machine est directement proportionnelle \u00e0 la surface de terrain que l'on peut d\u00e9fricher avant la tomb\u00e9e de la nuit. Le Watanabe R\u00e2teau \u00e0 pierres BlackBird<\/strong> a \u00e9t\u00e9 con\u00e7u selon cette logique. 9,5 m\u00e8tres de largeur de travail<\/strong> \u2014 le plus grand de sa cat\u00e9gorie au monde \u2014 il couvre jusqu'\u00e0 2,38 hectares par heure productive<\/strong> \u00e0 sa vitesse de travail maximale de 2,5 km\/h. Cela repr\u00e9sente environ quatre fois la couverture horaire du r\u00e2teau \u00e0 roches EP-EW-4000, avec une seule machine et un seul tracteur.<\/p>\n

Le BlackBird n'est pas simplement une version \u00e9largie d'un r\u00e2teau \u00e0 pierres classique. C'est un outil articul\u00e9 et tract\u00e9, con\u00e7u pour r\u00e9pondre aux exigences op\u00e9rationnelles du d\u00e9blaiement de pierres \u00e0 grande \u00e9chelle\u00a0: son ch\u00e2ssis articul\u00e9 permet de le replier pour le transport sur les chemins agricoles sans d\u00e9montage\u00a0; son attelage arri\u00e8re permet un couplage direct avec un concasseur de pierres THOR pour un fonctionnement continu en mode ratissage-concassage\u00a0; et son poids de 5\u00a0300\u00a0kg assure un contact constant des dents avec le sol sur toute leur largeur de 9,5\u00a0m\u00e8tres, m\u00eame sur les terrains accident\u00e9s en altitude. R\u00e9sultat\u00a0: une machine qui ne se contente pas de faire le travail des r\u00e2teaux \u00e0 pierres plus petits \u00e0 plus grande \u00e9chelle, mais qui offre une approche diff\u00e9rente du d\u00e9blaiement de pierres sur de grandes surfaces, tout simplement impossible avec des outils plus petits.<\/p>\n

\"Application<\/p>\n

Le BlackBird fait partie du Watanabe gamme de produits de gestion des terres<\/a> et est disponible aupr\u00e8s de Korea Watanabe Rock Crusher Tractor Co., Ltd. pour les grandes exploitations agricoles commerciales, les entrepreneurs en remise en \u00e9tat des terres et les projets de d\u00e9veloppement des terres agricoles en Cor\u00e9e et dans les r\u00e9gions environnantes.<\/p>\n

\n

\u25b6 \u00c0 qui s'adresse le BlackBird<\/p>\n

The BlackBird is not a machine for the typical family potato farm or small mixed holding. The 300 HP tractor requirement and 5,300 Kg machine weight position it squarely in the commercial agricultural contractor, large cooperative, and land reclamation project market. If your operation involves opening and clearing 50+ hectares of stone-affected land per season, or if you run stone clearance as a contract service for multiple large farms, the BlackBird’s cost-per-hectare economics become compelling. For smaller operations, the R\u00e2teau \u00e0 roches EP-EW-4000<\/a> (3,6 m, \u00e0 partir de 75 CV) est l'outil le plus appropri\u00e9.<\/p>\n<\/div>\n

All data sourced from Watanabe’s official partner site specifications. The BlackBird is a towed implement \u2014 it connects via drawbar, not Category 2 three-point hitch. The 1000 RPM PTO requirement is standard for large-frame agricultural tractors of 300+ HP; confirm that your tractor’s rear PTO is specified for 1000 RPM before ordering.<\/p>\n

\u24d8 Yield figure of 2.38 ha\/h is the manufacturer’s estimated maximum at 2.5 km\/h working speed and 9.5 m working width. Actual operational yield depends on field conditions, stone density, turning frequency, and driver technique \u2014 typical productive-hour output in Korean highland conditions will be lower. 1000 RPM PTO is required (not 540 RPM). All data from Watanabe official partner site.<\/p>\n

\n

\u26a0 Prise de force \u00e0 1000 tr\/min requise \u2014 et non \u00e0 540 tr\/min<\/p>\n

The BlackBird operates at 1000 RPM PTO input \u2014 the standard for large 300+ HP agricultural tractors, but a different shaft speed from the 540 RPM PTO used by all of Watanabe’s potato machinery and the DESTROYER compost barn aerator. Verify your tractor’s PTO configuration supports 1000 RPM output before ordering. Korean tractors in the 300+ HP class \u2014 John Deere 8R, New Holland T8, Fendt 900 series \u2014 all provide 1000 RPM PTO as standard.<\/p>\n<\/div>\n<\/div>\n

Comment fonctionne le BlackBird\u00a0\u2014 Ratissage, andainage et broyage en un seul passage<\/h2>\n

L'action de ratissage \u2014 Engagement du sol sur 9,5 m\u00e8tres<\/h3>\n

The BlackBird’s tines engage the soil surface as the 300 HP tractor pulls the machine slowly across the field at 0.8\u20132.5 km\/h. 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

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 “bridge” across ground hollows and miss surface stones in these zones; the BlackBird’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’s influence on frame depth is most indirect.<\/p>\n

Le cadre articul\u00e9 \u2014 Large couverture, transport pratique<\/h3>\n

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’s articulated frame solves this: the outer sections of the frame fold inward for transport, reducing the machine’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

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’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

\"R\u00e2teau<\/p>\n

Attelage arri\u00e8re\u00a0\u2014 R\u00e2teau et \u00e9crasement continus<\/h3>\n

The BlackBird’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

Cette combinaison de ratissage et de concassage r\u00e9volutionne le co\u00fbt du d\u00e9blaiement des pierres \u00e0 grande \u00e9chelle sur les terres agricoles. Sans elle, la proc\u00e9dure est la suivante\u00a0: ratissage du champ (un passage de tracteur) \u2192 ramassage des andains avec un chargeur \u2192 transport vers un concasseur ou un tas de pierres \u2192 concassage ou \u00e9limination. Avec le BlackBird et le THOR coupl\u00e9s\u00a0: un seul passage suffit pour d\u00e9blaiement, andainage et concassage simultan\u00e9s. Les pierres concass\u00e9es restent sur place sous forme de gravier qui peut \u00eatre incorpor\u00e9 au sol ou laiss\u00e9 en surface, \u00e9liminant ainsi totalement les co\u00fbts d'\u00e9limination.<\/p>\n

Vitesse de travail et production journali\u00e8re<\/h3>\n

At maximum working speed (2.5 km\/h) with the full 9.5-meter width, the BlackBird’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

La vitesse doit \u00eatre adapt\u00e9e \u00e0 la densit\u00e9 des pierres\u00a0: les charges de pierres importantes n\u00e9cessitent une vitesse de travail r\u00e9duite pour permettre un engagement complet des dents et une accumulation optimale des pierres\u00a0; les zones de pierres en surface plus l\u00e9g\u00e8res peuvent \u00eatre d\u00e9gag\u00e9es \u00e0 une vitesse plus \u00e9lev\u00e9e sans perte de qualit\u00e9. La plupart des op\u00e9rations de d\u00e9frichage en altitude en Cor\u00e9e du Sud se d\u00e9roulent \u00e0 une vitesse de 1,2 \u00e0 2,0\u00a0km\/h pour le d\u00e9frichage initial des champs pierreux \u00e9tablis, des vitesses plus \u00e9lev\u00e9es \u00e9tant possibles lors des passages suivants ou pour les charges de pierres plus l\u00e9g\u00e8res.<\/p>\n

\u25a0 9.5 m \u2014 World’s Largest Class<\/p>\n

Avec ses 9,5 m\u00e8tres de largeur, le BlackBird est le plus grand andaineur \u00e0 pierres de sa cat\u00e9gorie au monde. Son avantage en termes de largeur de travail par rapport aux andaineurs \u00e0 pierres classiques se traduit directement par une r\u00e9duction du nombre de passages par parcelle, des man\u0153uvres en bout de champ et une diminution des co\u00fbts de carburant et de main-d'\u0153uvre par hectare d\u00e9frich\u00e9. Pour les exploitations d\u00e9frichant des centaines d'hectares par saison, le calcul du co\u00fbt par hectare est sans \u00e9quivoque.<\/p>\n<\/div>\n

\n

\u25a0 Couplage THOR direct \u2014 Syst\u00e8me \u00e0 passage unique<\/p>\n

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’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

\n

\u25a0 Cadre articul\u00e9 \u2014 Transport pratique<\/p>\n

A 9.5-meter machine needs to move between fields. The BlackBird’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

\n

\u25a0 5\u00a0300 kg \u2014 Contact au sol sur toute la largeur<\/p>\n

The machine weight is distributed across the full 9.5-meter frame, ensuring all tines maintain consistent soil contact even on uneven highland terrain. A lightweight machine of the same width would bridge across hollows in the field and miss stones in low zones \u2014 a significant quality gap. The BlackBird’s weight ensures comprehensive coverage of every pass.<\/p>\n<\/div>\n

\n

\u25a0 D\u00e9bit jusqu'\u00e0 2,38 ha\/h<\/p>\n

At maximum speed, the BlackBird’s output of up to 2.38 ha\/h is the highest of any production rock rake. 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>\n

\n

O\u00f9 le r\u00e2teau \u00e0 roches BlackBird est utilis\u00e9<\/h2>\n

\ud83c\udf3f Ouverture \u00e0 grande \u00e9chelle de terres agricoles en Cor\u00e9e<\/h3>\n

Korea’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

Pour pr\u00e9parer ces terres \u00e0 la culture de pommes de terre, de l\u00e9gumes ou de fourrage, il est n\u00e9cessaire d'\u00e9liminer la couche de pierres en surface afin de permettre le passage des machines agricoles, semoirs et moissonneuses sans risque de dommages. La m\u00e9thode traditionnelle \u2013 ramassage manuel des pierres ou passages successifs de petits ramasseurs de pierres \u2013 est excessivement lente sur des surfaces sup\u00e9rieures \u00e0 10-20 hectares. Le BlackBird change la donne\u00a0: une parcelle de 100 hectares peut \u00eatre d\u00e9barrass\u00e9e des pierres de surface en environ 50 heures de travail machine, \u00e0 un rendement de 2 ha\/h. Cette technique rend ainsi le d\u00e9frichement des terres en altitude \u00e9conomiquement viable pour des exploitations \u00e0 l'\u00e9chelle commerciale, ce que les petits r\u00e2teaux \u00e0 pierres ne peuvent tout simplement pas faire.<\/p>\n

\ud83c\udfd9 Projets de mise en valeur des terres et d'infrastructures agricoles<\/h3>\n

Les programmes d'infrastructures agricoles du gouvernement cor\u00e9en, notamment le programme de mise en valeur des terres agricoles (\ub18d\uc9c0 \uac1c\ub7c9 \uc0ac\uc5c5) et les initiatives de d\u00e9veloppement rural dans les municipalit\u00e9s de montagne, pr\u00e9voient syst\u00e9matiquement le d\u00e9blaiement des pierres comme \u00e9tape pr\u00e9paratoire obligatoire avant toute am\u00e9lioration et culture des sols. Pour les entreprises soumissionnant \u00e0 ces programmes, le BlackBird offre un avantage concurrentiel tant en termes de prix unitaire (co\u00fbt par hectare inf\u00e9rieur gr\u00e2ce \u00e0 un d\u00e9bit plus \u00e9lev\u00e9) que de d\u00e9lais (r\u00e9alisation plus rapide dans le respect des \u00e9ch\u00e9ances contractuelles).<\/p>\n

The Korean Ministry of Agriculture’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

\ud83c\udf33 D\u00e9blaiement des pierres pour les zones de production de pommes de terre des hautes terres<\/h3>\n

La zone de culture de pommes de terre des hauts plateaux du Gangwon-do \u2014 Pyeongchang-gun, Jeongseon-gun, Inje-gun et les municipalit\u00e9s environnantes \u2014 pr\u00e9sente une teneur importante en pierres dans ses sols d'origine granitique et basaltique. La densit\u00e9 de pierres est si \u00e9lev\u00e9e dans de nombreux champs que\u2026 R\u00e2teau \u00e0 roches EP-EW-4000<\/a> (3,6 m) est utilis\u00e9 par la plupart des producteurs pour le premier passage de d\u00e9gagement chaque printemps \u2014 une pratique saisonni\u00e8re de gestion des pierres qui est la norme dans cette r\u00e9gion.<\/p>\n

Pour les grandes exploitations de pommes de terre et les coop\u00e9ratives g\u00e9rant plus de 50 hectares, le d\u00e9broussaillage printanier de l'EP-EW-4000 sur l'ensemble de la zone de production repr\u00e9sente un investissement en temps consid\u00e9rable, empi\u00e9tant directement sur le calendrier des plantations. Le BlackBird, avec sa largeur de travail de 9,5 m\u00e8tres, effectue le m\u00eame d\u00e9broussaillage printanier en environ 251 tonnes et 5 tonnes de moins, permettant ainsi aux \u00e9quipements de plantation de d\u00e9marrer comme pr\u00e9vu. Pour les exploitations utilisant d\u00e9j\u00e0 des tracteurs de plus de 300 ch pour d'autres usages (gros rotoculteurs, mat\u00e9riel de r\u00e9colte tra\u00een\u00e9 ou outils de travail du sol lourds), le BlackBird s'int\u00e8gre parfaitement au parc de tracteurs existant, sans n\u00e9cessiter l'achat d'une machine suppl\u00e9mentaire.<\/p>\n

\ud83c\udf3f Conversion des terres post-foresti\u00e8res<\/h3>\n

La Cor\u00e9e poursuit un programme de conversion des terres foresti\u00e8res marginales en terres agricoles, notamment dans les zones o\u00f9 les anciennes plantations foresti\u00e8res sont abandonn\u00e9es et o\u00f9 les terres sont \u00e9valu\u00e9es en vue d'une utilisation productive alternative. Apr\u00e8s l'abattage des arbres et l'enl\u00e8vement des souches, les terres foresti\u00e8res sont g\u00e9n\u00e9ralement recouvertes de pierres, de fragments de racines et pr\u00e9sentent un sol accident\u00e9 qui doit \u00eatre d\u00e9frich\u00e9 et nivel\u00e9 avant que les outils agricoles classiques puissent y \u00eatre travaill\u00e9s.<\/p>\n

The BlackBird’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. In one operation, the surface can be cleared of stones and the collected material crushed and left as granular surface mulch \u2014 significantly advancing the land preparation timeline compared to sequential individual-implement operations.<\/p>\n

\u2461 BlackBird + THOR \u2014 R\u00e2teau et broyage en un seul passage Le plus efficace<\/span><\/p>\n

Couplez le Concasseur de roches THOR 3.0<\/a> directly to the BlackBird’s rear hitch. The BlackBird rakes and windrows stones; the THOR immediately behind crushes them into aggregate in the same forward pass. Crushed aggregate remains on the field \u2014 no collection, no disposal, no transport cost. The most operationally efficient configuration for large-scale clearing where on-site stone reduction is the goal.<\/p>\n<\/div>\n

\n

\u2462 Pr\u00e9-Clear THOR autonome + BlackBird<\/p>\n

Pour les champs tr\u00e8s rocailleux, utilisez le THOR 2.4<\/a> or THOR 3.0 first to crush the largest surface boulders that exceed the BlackBird’s handling capacity, then follow with the BlackBird for comprehensive surface raking. This two-pass approach handles extreme stone density conditions that would overload a single-pass combined operation.<\/p>\n<\/div>\n<\/div>\n

\n
\"Certifications<\/div>\n
\n

The BlackBird’s position as the world’s largest production rock rake of its class is not primarily a marketing claim \u2014 it reflects a design engineering challenge that Watanabe solved in a way that competitors have not. Building a 9.5-meter tine array that maintains consistent ground contact across its full span, folds to a practical transport width, and provides sufficient structural rigidity at 5,300 Kg to be useful in real-world uneven highland terrain requires a frame design, articulation system, and tine specification that cannot be simply scaled from a smaller machine.<\/p>\n

The rear hitch integration with the THOR crusher \u2014 allowing a direct mechanical coupling that maintains alignment between the raking and crushing operations in the same tractor pass \u2014 is an engineering design feature, not a bolt-on modification. It reflects Watanabe’s development of the BlackBird as an integrated part of their stone clearance product line rather than as a standalone implement.<\/p>\n<\/div>\n<\/div>\n

Foire aux questions \u2013 R\u00e2teau \u00e0 roches BlackBird<\/h2>\n
\n
\n

Why is the BlackBird called the world’s largest rock rake in its class?<\/p>\n

The 9.5-meter working width is the largest available in production-series PTO-driven agricultural rock rakes globally. 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’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

\n

Quel mod\u00e8le de concasseur THOR est compatible avec l'attelage arri\u00e8re BlackBird\u00a0?<\/p>\n

Le Concasseur de roches THOR 3.0<\/a> (230 HP, drawbar Kit) is the primary coupling partner for the BlackBird in the Watanabe system. The THOR 3.0’s drawbar kit configuration allows it to be connected to the BlackBird’s rear hitch, pulled by the same 300+ HP tractor that operates the BlackBird. The THOR 2.4<\/a> (180 HP) peut \u00e9galement \u00eatre compatible dans certaines configurations \u2014 confirmez la compatibilit\u00e9 de l'accouplement pour votre tracteur et votre mod\u00e8le THOR sp\u00e9cifiques lorsque vous nous contactez.<\/p>\n<\/div>\n

\n

De quel espace en bordure de promontoire le BlackBird a-t-il besoin pour faire demi-tour ?<\/p>\n

The BlackBird’s headland turning requirement depends on whether the THOR crusher is coupled. 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

\n

Le BlackBird peut-il g\u00e9rer de tr\u00e8s gros rochers ?<\/p>\n

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’s stone size description and a photograph of the surface conditions.<\/p>\n<\/div>\n

\n

Pourquoi le BlackBird a-t-il besoin d'une prise de force \u00e0 1000 tr\/min plut\u00f4t qu'\u00e0 540 tr\/min ?<\/p>\n

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’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’s specification sheet before ordering.<\/p>\n<\/div>\n

\n

Que faire des andains de pierres apr\u00e8s le col de BlackBird ?<\/p>\n

Three main options: (1) Crush in place using the THOR crusher coupled to the BlackBird’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 Ramasse-roches CT-2100<\/a> and transport to a defined disposal or use point \u2014 the CT-2100’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

\n

Le BlackBird est-il adapt\u00e9 aux pentes des hauts plateaux cor\u00e9ens\u00a0?<\/p>\n

The BlackBird’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. Contact us to discuss your specific field mix.<\/p>\n<\/div>\n

Comment le BlackBird se d\u00e9place-t-il sur les pistes d'acc\u00e8s aux fermes cor\u00e9ennes ?<\/p>\n

Le ch\u00e2ssis articul\u00e9 se replie hydrauliquement, passant d'une largeur de travail de 9,5 m\u00e8tres \u00e0 une largeur de transport nettement plus r\u00e9duite. Cette derni\u00e8re, correspondant \u00e0 la configuration de production actuelle, doit \u00eatre confirm\u00e9e avec nous. Pour acc\u00e9der aux chemins agricoles cor\u00e9ens, la largeur de la machine repli\u00e9e et la longueur totale combin\u00e9e du tracteur et du BlackBird sont les dimensions cl\u00e9s. En g\u00e9n\u00e9ral, les chemins d'acc\u00e8s aux exploitations agricoles des hauts plateaux cor\u00e9ens, d'une largeur de 3,5 \u00e0 4 m\u00e8tres, permettent le passage du BlackBird en position de transport repli\u00e9e. Pour les chemins plus \u00e9troits, un d\u00e9blaiement ou un \u00e9largissement peut \u00eatre n\u00e9cessaire avant le transport de la machine jusqu'au champ. Veuillez nous indiquer la largeur de votre chemin d'acc\u00e8s et la pr\u00e9sence \u00e9ventuelle de portails ou de ponts limitant la largeur de votre exploitation lorsque vous nous contactez pour une \u00e9valuation de la compatibilit\u00e9.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

“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.”<\/p>\n<\/div>\n

“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.”<\/p>\n<\/div>\n

“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. I have the Korea Watanabe team to thank for the pre-sale compatibility check \u2014 they confirmed the rear hitch coupling setup with the THOR 3.0 before I ordered, and the combined system has worked exactly as described in every season.”<\/p>\n<\/div>\n

“Our cooperative was awarded a government agricultural land improvement contract covering 90 hectares of stone-affected highland fields across three member farms. 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’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.”<\/p>\n<\/div>\n

“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. Planted potatoes into the new land the same spring.”<\/p>\n<\/div>\n

“We took on 60 hectares of former plantation pine land that was being converted to agricultural use following the regional forestry retirement program. After stump removal and initial rough grading, the surface was covered with root fragments, stone debris from the forest floor, and exposed rock from the grading work. 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.”<\/p>\n<\/div>\n<\/div>\n<\/div>\n
