Korea's Highest-Capacity Tractor-Mounted Stone Crusher
The Watanabe THOR 3.0 is the highest-capacity tractor-mounted stone crusher in the Watanabe range currently available in Korea. At 3.0 meters working width with 108 main + 8 side carbide teeth on a 600 mm rotor, it processes stones up to 40 cm diameter at 230 HP minimum input. The Drawbar Kit is included as standard, providing the same pull-mode slope configuration as the THOR 2.4 for operations where gradient work is required.
The THOR 3.0 is the model chosen by large-scale farm development companies, land clearance contractors, and government project teams — operations where daily area coverage and the ability to process the largest stones in a single pass are the primary selection criteria. For operations where narrow rows, tight orchard spacing, or gradients above 20% are the main challenge, the Concasseur de pierres THOR 2.4 (180 HP, 2.4 m) is typically the better fit at a lower tractor power requirement.
For the largest-scale operations combining stone raking and crushing in one pass, the THOR 3.0's Drawbar Kit allows direct coupling behind the BlackBird rock rake (9.5 m, 300 HP) — the BlackBird rakes and windrows stones ahead, and the THOR 3.0 immediately behind crushes those windrows in the same forward movement.

Engineering Features
■ 108+8 Carbide Teeth, 600 mm Rotor
108 main teeth and 8 side teeth on a 600 mm rotor diameter — more teeth and a larger rotor than the THOR 2.4 (90+6 teeth, 550 mm). This produces a finer crushed output per pass at equivalent working speed, beneficial for road base and agricultural seedbed applications requiring uniform particle size.
■ Oil-Cooled Dual Transmission
Dedicated oil cooler and radiator circuit at 230 HP input. The THOR 3.0 runs at higher sustained power than the 2.4, making the thermal management system correspondingly more critical. Enables full working days in Korean summer conditions without overheating interruptions.
■ Drawbar Kit — Included Standard
Same pull-mode configuration as the THOR 2.4 Kit Drawbar. On road construction and land opening projects with access gradients, pull-mode improves tractor stability. Included in the standard price. Requires 2 hydraulic control valves on the tractor.
■ Wear-Resistant Steel Construction
Body liners, counter-blades, and the adjustable output grid are wear-resistant steel with bolt-on replacement design. The 2,800 Kg machine weight reflects the structural specification needed to maintain consistent rotor engagement at 230 HP working load across varied Korean rock types.
■ BlackBird Rear Hitch Compatible
The THOR 3.0's Drawbar Kit couples directly behind the BlackBird Rock Rake's rear hitch. One 300+ HP tractor pulls both machines — the BlackBird rakes and windrows stones at 9.5 m width, the THOR 3.0 crushes them in the same forward pass. The most efficient large-area single-pass clearing system in the Watanabe range.
How the THOR 3.0 Works — PTO Drive, Rotor Mechanism, and Daily Output
The THOR 3.0 operates on the same fundamental engineering principle as the THOR 2.4 but at a higher specification in every parameter. Power from the tractor's 1000 RPM rear PTO shaft is transmitted through the dual-stage gearbox to the 600 mm diameter rotor. At 230 HP sustained input, the rotor carries 108 main + 8 side carbide-tipped teeth across the full 3.0 m working width, each tooth delivering high-velocity impact energy to the stone material at the working depth.
Impact Crushing — Carbide Teeth on a 600 mm Rotor
At 1000 RPM, the carbide tooth tips on the THOR 3.0's 600 mm rotor travel at approximately 31 m/s at impact. This tip speed — slightly higher than the THOR 2.4's 550 mm rotor — combined with the higher tooth count (108 vs 90 main teeth) and the 230 HP power supply produces finer crushed output per pass than the THOR 2.4 at equivalent forward speed. For road base applications where fine, uniform aggregate is preferred for compaction, and for agricultural seedbed preparation where consistent small fragment size reduces subsequent tillage energy, the THOR 3.0's output quality at working speed is measurably finer than the smaller model. Stones up to 40 cm diameter are processed in a single pass — the 10 cm larger maximum stone capacity versus the THOR 2.4 directly reflects the larger rotor diameter and higher tooth count.
Hydraulic Output Control and Grid System
Two hydraulic control valve outlets on the tractor are required for the THOR 3.0: one for the rear hood hydraulic actuator (which controls the output grid opening and crushed material particle size), and one for the Drawbar Kit configuration change. The output grid is adjusted from the tractor cab during operation — the operator changes particle size setting without stopping or exiting. The grid itself is wear-resistant steel, bolt-on replaceable as a complete unit or in individual sections.
Realistic Daily Coverage in Korean Conditions
At 3.0 m working width and a typical working speed of 1.0–2.0 km/h depending on stone density, the theoretical pass coverage rate is 0.3–0.6 ha per hour of active forward travel. Accounting for headland turns, tooth inspections, and operator breaks — typically 70–80% productive forward-travel time during a full working day in standard Korean highland field conditions — a realistic daily coverage on open agricultural terrain with moderate stone density is approximately 5–10 hectares. Heavy stone density or frequent short field lengths reduces this toward the lower end; lighter stone loads and large open fields move it toward the upper end. These figures are for the crushing pass alone — if a CT-2100 rock picker follow-up pass is planned, schedule approximately the same daily coverage for the picking pass on the cleared ground.
Applications in Korea
Large-Scale Agricultural Land Reclamation
In granite-rich areas of Chungcheongnam-do and Jeollabuk-do, the THOR 3.0 clears surface rocks on fields being converted from rough land to cultivated agricultural production. At the THOR 3.0's 3.0 m working width, a 100-hectare reclamation project can be completed in approximately 8–10 productive working days, giving development contractors a viable project timeline within the Korean agricultural season calendar.
Farm Road Construction and Maintenance
Throughout the apple, persimmon, and citrus belts of South and North Gyeongsang, contractors use the THOR 3.0 to build and maintain all-weather farm roads. The 3.0 m working width matches standard Korean farm road widths, allowing a single pass to complete the road surface width where narrower machines require two overlapping passes.
Government Agricultural Land Development Programs
Government agricultural land development programs (농지 개량 사업) and rural infrastructure contracts specify machines in the THOR 3.0 class for their throughput capacity. Contractors with a THOR 3.0 in their equipment fleet can credibly bid on larger contract packages with tighter completion deadlines. For projects requiring pre-clearance raking before the crusher pass, the BlackBird Rock Rake (9.5 m, 300 HP) operates as the lead machine with the THOR 3.0 coupled directly on the rear hitch.
Post-Crushing Collection — CT-2100 Rock Picker Follow-Up
For operations requiring completely stone-free fields (potato production, seed crop preparation, precision vegetable cultivation), the ramasse-roches CT-2100 collects the crushed fragments left by the THOR 3.0 pass and removes them completely from the field.

Manufacturing and Build Quality
The THOR 3.0 is manufactured at Watanabe's Castro facility under full in-house production control. The 3.0 m rotor assembly — the most demanding component in the machine in terms of balance and structural integrity at 230 HP sustained load — is machined, assembled, and balance-checked at the factory before installation. The 2,800 Kg machine weight reflects the structural specification required to maintain consistent rotor engagement and ground contact at 230 HP working load across Korea's varied rock types: from soft sedimentary sandstone in South Chungcheong coastal zones to hard granite in Gangwon-do highlands and Jeju Island basalt. The heavier build is not excess weight — it is the mass needed for stability at this power level.
Why the THOR 3.0 Performs in Korean Conditions
Korean highland granite and Jeju basalt both fall in the Mohs 6–7 hardness range — the same range for which the THOR 3.0's 108 + 8 carbide tooth specification was developed and validated in Brazilian conditions. Korean summer ambient temperatures during peak clearing seasons (33–38°C in highland regions, July–August) match the Brazilian conditions that drove the oil-cooling transmission design at 230 HP. The combination of high rock hardness and high ambient temperature is the most demanding operating condition for a tractor-mounted stone crusher — and it is the precise combination the THOR 3.0 was built to handle continuously.
Korea Local Stock and Service
Korea Watanabe maintains the THOR 3.0 in local inventory in Ansan-si, Gyeonggi-do, along with replacement carbide tooth sets (116 teeth per full set for the THOR 3.0) and key wear component sets. Local stock enables delivery within the Korean agricultural season calendar. For government project contractors and land development companies working against fixed project deadlines, local stock availability is a direct project risk reduction.
Korean-language technical support is available from the Korea Watanabe team throughout the machine's operating life — product commissioning, maintenance scheduling, operational guidance, and wear part ordering. Warranty terms covering mechanical defects in the drive system, rotor assembly, and frame structure are confirmed at the time of purchase.
Foire aux questions
When should I choose the THOR 3.0 over the THOR 2.4?
Choose the THOR 3.0 when: your annual clearing area consistently exceeds 300 hectares; you regularly encounter stones above 30 cm; your fields are open without tight row constraints; your tractor is 230 HP or above; and daily throughput is the key metric. For orchards, narrow ginseng rows, slopes above 20%, or tractors below 230 HP, the THOR 2.4 is the appropriate choice. The Kit Drawbar pull-mode on the THOR 2.4 is specifically designed for Korean mountain orchard conditions where the THOR 3.0's wider footprint is a disadvantage.
Why does the THOR 3.0 require 2 hydraulic control valves?
The THOR 3.0 uses hydraulic actuation for two independent functions: the rear hood opening (controls output fragment size) and the Drawbar Kit configuration change. Each function requires one hydraulic remote valve outlet on the tractor. Most Korean and international tractors at 230 HP have at least 3–4 rear remote valves — this is rarely a limiting factor in this power class. Verify your tractor's rear valve count if unsure.
Can the THOR 3.0 couple with the BlackBird Rock Rake?
Yes — the THOR 3.0 with Drawbar Kit couples behind the BlackBird Rock Rake using the BlackBird's rear hitch system. The combined configuration requires a 300+ HP tractor. In this arrangement, the BlackBird rakes and windrows stones at 9.5 m working width, and the THOR 3.0 immediately behind crushes the windrows — rake and crush in one forward pass. Contact us to confirm the specific coupling configuration and tractor HP requirement for your operation.
What tractor is needed for the THOR 3.0?
230 HP minimum, 1000 RPM rear PTO, Category 2 three-point hitch, and 2 hydraulic remote valve outlets. Compatible models include: John Deere 7R 230 / 8R series; New Holland T7.230 / T8 series; Kubota M7 upper range; Fendt 700 and 800 Vario series. Korean domestic tractor brands in the 230+ HP class are less common — most THOR 3.0 users in Korea operate imported European or North American tractors in the 230–350 HP class. We verify compatibility for your specific tractor model before delivery.
What is the realistic daily area coverage?
At a working speed of 1.5 km/h and 3.0 m working width, the theoretical coverage rate is 0.45 ha per hour of productive travel. Accounting for headland turns, tooth checks, and operator breaks — typically 70–80% productive time during a full working day — a realistic daily coverage is approximately 6–10 hectares in moderate stone density Korean highland conditions. Heavier stone density reduces this figure; lighter stone loads and larger open fields move toward the upper range.
Are Korean government subsidies available for the THOR 3.0?
Agricultural machinery subsidies (농업기계화 촉진 지원사업) are administered annually by the Ministry of Agriculture through provincial agricultural technology centers (농업기술센터). Eligibility for specific models depends on the current year's approved equipment categories. Confirm current eligibility with your regional center before purchase. We can provide the technical specification documentation required for subsidy applications.
How does the THOR 3.0 maintenance differ from the THOR 2.4?
Maintenance requirements are essentially the same: inspect and replace carbide teeth at regular intervals during the clearing season; check transmission oil level and condition before each extended working period; clean the rotor and housing daily; inspect the hydraulic hood and adjustable grid; lubricate all grease points per the operator manual schedule. The THOR 3.0 has 116 teeth (vs 96 on the THOR 2.4) — a full tooth set change takes proportionally longer. Carry a supply of replacement carbide teeth on site during intensive clearing contracts.
Customer Reviews
Jo Seong-hun — Agricultural Land Development Company, Jeonju, Jeollabuk-do (2024)
★★★★★
"We contract land clearing for rice and vegetable farms across North Jeolla — typical projects are 50–150 hectares of granite-heavy former orchard land. The THOR 3.0 finishes these projects in timelines that our contracts can price competitively. Adding the BlackBird Rock Rake this year for the combined rake-and-crush configuration has further reduced total passes per hectare."
Nam Dong-hyun — Forestry Bureau Contractor, Chuncheon, Gangwon-do (2024–2025)
★★★★★
"Government contracts for highland clearing in Gangwon-do — open terrain, significant granite surface rock, including stones above 30 cm that the THOR 2.4 I had previously would struggle with. The THOR 3.0 handles these consistently. Korea Watanabe had replacement carbide teeth ready domestically — next-day delivery when I needed them."
Kwon Tae-sik — Potato and Onion Farm (85 ha), Seogwipo, Jeju (2024)
★★★★★
"Spring stone clearance on 85 hectares of Jeju basalt soil — the THOR 3.0's 3 m width completes the full area in 7–8 working days. The oil cooling is essential for Jeju summer work. We ran 9-hour days in July without any heat stops. The CT-2100 rock picker follow-up completes the seedbed before the potato planter goes in."
Im Seung-yeon — Road Construction Contractor, Hongseong-gun, South Chungcheong (2025)
★★★★★
"Building farm access roads across South Chungcheong. The THOR 3.0 in pull-mode builds the road base in one pass while the output grid setting determines coarse gravel or finer surface material. The Drawbar Kit pull configuration handles extended uphill sections well — two seasons with consistent daily output."
Oh Byung-chan — Agricultural Cooperative, Gochang-gun, Jeollabuk-do (2025)
★★★★★
"Cooperative machine shared across 8 member farms — about 120 ha cleared per year total. At 3 m width, one visit to each member farm covers the full area in 1–2 days, which works well for our cooperative scheduling model. Tractor compatibility confirmed by Korea Watanabe before purchase — the 2 remote valve requirement was met without any modification."
Shin Hyun-woo — Agricultural Land Developer, Gyeonggi-do (2024)
★★★★★
"Standard clearing system for our land development operation: THOR 3.0 crush → CT-2100 rock picker collect → PSW-3200 rotavator till. Produces development-ready land in 3–4 days per hectare on typical Gyeonggi stone loads. The pre-sale workflow planning with Korea Watanabe made the first season considerably smoother."
