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

O desmatamento em larga escala \u2014 abertura de novas \u00e1reas agr\u00edcolas, recupera\u00e7\u00e3o de campos abandonados cobertos por pedras na superf\u00edcie, prepara\u00e7\u00e3o de terrenos montanhosos para aterro \u2014 \u00e9 uma opera\u00e7\u00e3o em que a largura da m\u00e1quina \u00e9 diretamente proporcional \u00e0 quantidade de terra que se consegue desmatar antes do anoitecer. A Watanabe Ancinho de pedra BlackBird<\/strong> Foi projetado com base nessa l\u00f3gica. 9,5 metros de largura de trabalho<\/strong> \u2014 o maior da sua classe em todo o mundo \u2014 cobre at\u00e9 2,38 hectares por hora produtiva<\/strong> em sua velocidade m\u00e1xima de trabalho de 2,5 km\/h. Isso representa aproximadamente quatro vezes a cobertura hor\u00e1ria do rastelo de rochas EP-EW-4000, com uma \u00fanica m\u00e1quina e um \u00fanico trator.<\/p>\n

O BlackBird n\u00e3o \u00e9 simplesmente uma vers\u00e3o mais larga de um rastelo de pedras convencional. \u00c9 um implemento articulado rebocado, projetado para atender \u00e0s necessidades operacionais da remo\u00e7\u00e3o de pedras em larga escala: a estrutura articulada permite que a m\u00e1quina seja dobrada para transporte em estradas rurais sem desmontagem; o engate traseiro possibilita o acoplamento direto a um britador de pedras THOR para opera\u00e7\u00e3o cont\u00ednua de rastelamento e britagem; e o peso estrutural de 5.300 kg garante que os dentes tenham contato consistente com o solo em toda a extens\u00e3o de 9,5 metros, mesmo em terrenos irregulares de alta altitude. O resultado \u00e9 uma m\u00e1quina que n\u00e3o apenas realiza o trabalho de rastelos de pedras menores em maior escala, mas possibilita uma abordagem diferente para a remo\u00e7\u00e3o de pedras em grandes \u00e1reas, algo simplesmente impratic\u00e1vel com implementos menores.<\/p>\n

\"Aplica\u00e7\u00e3o<\/p>\n

O BlackBird faz parte do Watanabe linha de produtos para gest\u00e3o de terras<\/a> e est\u00e1 dispon\u00edvel atrav\u00e9s da Korea Watanabe Rock Crusher Tractor Co., Ltd. para grandes opera\u00e7\u00f5es agr\u00edcolas comerciais, empreiteiras de recupera\u00e7\u00e3o de terras e projetos de desenvolvimento de terras agr\u00edcolas em toda a Coreia e regi\u00f5es vizinhas.<\/p>\n

\n

\u25b6 Para quem o BlackBird foi projetado<\/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 EP-EW-4000 Ancinho de Pedra<\/a> (3,6 m, de 75 HP) \u00e9 a ferramenta mais apropriada.<\/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 \u00c9 necess\u00e1rio um torque de 1000 RPM na tomada de for\u00e7a (TDF), e n\u00e3o de 540 RPM.<\/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

<\/p>\n

\n

Como funciona o BlackBird \u2014 Recolhe, enleira e esmaga em uma \u00fanica passada<\/h2>\n

A\u00e7\u00e3o de Rasteamento \u2014 Engajamento do Solo em 9,5 Metros<\/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

A estrutura articulada \u2014 ampla cobertura, transporte pr\u00e1tico<\/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

\"Recurso<\/p>\n

Engate traseiro \u2014 Raspe e esmague continuamente<\/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

Essa combina\u00e7\u00e3o de rastelo e britador altera drasticamente a economia da remo\u00e7\u00e3o de pedras em larga escala em terras agr\u00edcolas. Sem ela, a sequ\u00eancia \u00e9: rastelar o campo (uma passagem do trator) \u2192 recolher as leiras com uma p\u00e1 carregadeira \u2192 transportar para um britador ou pilha de pedras \u2192 britar ou descartar. Com o BlackBird e o THOR acoplados: uma \u00fanica passagem limpa, forma leiras e brita simultaneamente. A pedra britada permanece no local como cascalho, que pode ser incorporado ao perfil do solo ou deixado como material superficial \u2014 eliminando completamente o custo de descarte.<\/p>\n

Velocidade de trabalho e produ\u00e7\u00e3o di\u00e1ria<\/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

A velocidade deve ser adequada \u00e0 densidade das pedras: cargas de pedras mais pesadas exigem uma velocidade de trabalho mais lenta para permitir o completo engajamento dos dentes e o ac\u00famulo de pedras; \u00e1reas com menos pedras na superf\u00edcie podem ser limpas em velocidades mais altas sem perda de qualidade. A maioria das opera\u00e7\u00f5es de limpeza em \u00e1reas montanhosas da Coreia utiliza velocidades entre 1,2 e 2,0 km\/h para a limpeza inicial de campos pedregosos j\u00e1 estabelecidos, com velocidades mais altas poss\u00edveis em passagens subsequentes ou em cargas de pedras mais leves.<\/p>\n

Por que o BlackBird muda a economia da remo\u00e7\u00e3o de pedras em larga escala<\/h2>\n

\"Ancinho<\/p>\n

\n
\n

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

Com 9,5 metros, o BlackBird \u00e9 o maior rastelo rochoso de produ\u00e7\u00e3o da sua categoria em todo o mundo. A vantagem da largura de trabalho em rela\u00e7\u00e3o a todos os rastelos rochos convencionais se traduz diretamente em menos passagens por campo, menos manobras nas cabeceiras e menor custo de combust\u00edvel e m\u00e3o de obra por hectare desmatado. Para opera\u00e7\u00f5es que desmatam centenas de hectares por safra, o c\u00e1lculo do custo por hectare torna a escolha do BlackBird bastante vantajosa.<\/p>\n<\/div>\n

\n

\u25a0 Acoplamento THOR direto \u2014 Sistema de passagem \u00fanica<\/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 Chassi articulado \u2014 Transporte pr\u00e1tico<\/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 5.300 kg \u2014 Contato total com o solo<\/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 Produ\u00e7\u00e3o de at\u00e9 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

Onde o ancinho de pedras BlackBird \u00e9 usado<\/h2>\n

\ud83c\udf3f Abertura de terras agr\u00edcolas em larga escala na Coreia<\/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

A abertura desta terra para o cultivo de batata, hortali\u00e7as ou forragem exige a remo\u00e7\u00e3o da camada superficial de pedras at\u00e9 um n\u00edvel em que m\u00e1quinas agr\u00edcolas, plantadeiras e colheitadeiras possam operar sem danos mec\u00e2nicos. A abordagem tradicional \u2014 coleta manual de pedras ou passagens com pequenos coletores de pedras \u2014 \u00e9 proibitivamente lenta em \u00e1reas acima de 10 a 20 hectares. O BlackBird muda a escala do que \u00e9 praticamente poss\u00edvel: um bloco de 100 hectares pode ser limpo de pedras superficiais em aproximadamente 50 horas produtivas de m\u00e1quina, com uma produ\u00e7\u00e3o de 2 ha\/h, tornando a abertura de terras em \u00e1reas de altitude economicamente vi\u00e1vel para opera\u00e7\u00f5es em escala comercial que os pequenos rastelos de pedras simplesmente n\u00e3o conseguem atender.<\/p>\n

\ud83c\udfd9 Projetos de Recupera\u00e7\u00e3o de Terras e Infraestrutura Agr\u00edcola<\/h3>\n

Os programas de infraestrutura agr\u00edcola do governo coreano \u2014 particularmente o programa de Recupera\u00e7\u00e3o de Terras Agr\u00edcolas (\ub18d\uc9c0 \uac1c\ub7c9 \uc0ac\uc5c5) e as iniciativas de desenvolvimento rural em munic\u00edpios de terras altas \u2014 incluem regularmente a remo\u00e7\u00e3o de pedras como uma etapa preparat\u00f3ria obrigat\u00f3ria antes do in\u00edcio do melhoramento e cultivo do solo. Para as empresas contratadas que participam de licita\u00e7\u00f5es para esses programas governamentais, a BlackBird oferece uma vantagem competitiva tanto no pre\u00e7o unit\u00e1rio (menor custo por hectare devido \u00e0 maior produtividade) quanto no cronograma do projeto (conclus\u00e3o mais r\u00e1pida dentro dos prazos contratuais).<\/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 Remo\u00e7\u00e3o de pedras para zonas de produ\u00e7\u00e3o de batata das Terras Altas<\/h3>\n

A regi\u00e3o montanhosa de cultivo de batata em Gangwon-do \u2014 Pyeongchang-gun, Jeongseon-gun, Inje-gun e munic\u00edpios vizinhos \u2014 possui um teor significativo de pedras em seus solos derivados de granito e basalto. A densidade de pedras \u00e9 t\u00e3o alta em muitos campos que... Ancinho de rocha EP-EW-4000<\/a> (3,6 m) \u00e9 usado pela maioria dos produtores para a passagem inicial de limpeza a cada primavera \u2014 uma pr\u00e1tica sazonal de gest\u00e3o de pedras que \u00e9 padr\u00e3o nesta regi\u00e3o.<\/p>\n

Para grandes fazendas comerciais de batata e cooperativas com mais de 50 hectares, operar o trator EP-EW-4000 na limpeza de primavera em toda a \u00e1rea de produ\u00e7\u00e3o representa um investimento de tempo significativo, que compete diretamente com o cronograma de plantio. O BlackBird, com sua largura de trabalho de 9,5 metros, realiza a mesma limpeza de pedras na primavera em aproximadamente 251 TP5T do mesmo tempo, liberando o equipamento de plantio para iniciar no prazo previsto. Para opera\u00e7\u00f5es que j\u00e1 utilizam tratores com mais de 300 HP para outros fins \u2014 como grandes rotocultivadores, equipamentos de colheita rebocados ou implementos de cultivo pesado \u2014 o BlackBird se integra \u00e0 infraestrutura existente sem a necessidade de adquirir uma m\u00e1quina espec\u00edfica.<\/p>\n

\ud83c\udf3f Convers\u00e3o de terras p\u00f3s-florestais<\/h3>\n

A Coreia mant\u00e9m um programa cont\u00ednuo de convers\u00e3o de terras florestais marginais em terras agr\u00edcolas, especialmente em \u00e1reas onde antigas planta\u00e7\u00f5es florestais est\u00e3o sendo desativadas e a terra \u00e9 avaliada para uso produtivo alternativo. As terras p\u00f3s-florestais \u2014 ap\u00f3s o corte das \u00e1rvores e a remo\u00e7\u00e3o dos tocos \u2014 geralmente ficam cobertas por pedras na superf\u00edcie, fragmentos de ra\u00edzes e solo irregular, que precisam ser limpos e nivelados antes que implementos agr\u00edcolas padr\u00e3o possam ser utilizados.<\/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

\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

Perguntas frequentes \u2013 Ancinho para pedras 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

Qual modelo de triturador THOR \u00e9 compat\u00edvel com o engate traseiro BlackBird?<\/p>\n

O Triturador de rochas 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) tamb\u00e9m pode ser compat\u00edvel em determinadas configura\u00e7\u00f5es \u2014 confirme a compatibilidade do acoplamento para o seu trator espec\u00edfico e modelo THOR ao entrar em contato conosco.<\/p>\n<\/div>\n

\n

De que espa\u00e7o no promont\u00f3rio o BlackBird precisa para dar a volta?<\/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

O BlackBird consegue lidar com pedras muito grandes?<\/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

Por que o BlackBird precisa de uma tomada de for\u00e7a (TDF) de 1000 RPM em vez de 540 RPM?<\/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

O que devo fazer com os montes de pedra depois da passagem 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 Coletor de pedras 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

O BlackBird \u00e9 adequado para encostas nas terras altas da Coreia?<\/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

Como o BlackBird se comporta no transporte em estradas rurais coreanas?<\/p>\n

A estrutura articulada dobra-se hidraulicamente, reduzindo a largura de trabalho de 9,5 metros para uma largura de transporte significativamente menor \u2014 a largura exata de transporte deve ser confirmada conosco para a configura\u00e7\u00e3o de produ\u00e7\u00e3o atual. Para acesso por estradas agr\u00edcolas coreanas, a largura da m\u00e1quina dobrada e o comprimento total combinado do trator + BlackBird s\u00e3o as dimens\u00f5es principais. Em geral, estradas de acesso a fazendas em terras altas coreanas com 3,5 a 4,0 metros de largura podem acomodar o BlackBird na posi\u00e7\u00e3o de transporte dobrada; rotas de acesso mais estreitas podem exigir desmatamento ou alargamento antes que a m\u00e1quina possa ser transportada para o campo. Informe a largura da sua estrada de acesso \u00e0 fazenda e quaisquer port\u00f5es ou pontes com restri\u00e7\u00e3o de largura ao entrar em contato conosco para a avalia\u00e7\u00e3o de adequa\u00e7\u00e3o.<\/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

\u2605\u2605\u2605\u2605\u2605<\/p>\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
