THOR 3.0 Rock Crusher with Drawbar Kit – 230 HP Heavy-Duty Stone Crusher for Tractor

The Watanabe THOR 3.0 is the most powerful tractor-mounted stone crusher and mulcher currently available in Korea. Designed for professional contractors and large-scale farmers who need to clear rocky farmland, prepare forest roads, or build stable farm tracks in a single pass, this 3-meter-wide machine combines extreme crushing power with forestry mulcher versatility.

Equipped with the exclusive Kit Drawbar system, the THOR 3.0 can be used both in rear-mounted (standard 3-point) and front-pull configuration, making it the preferred choice across Jeolla, Gyeongsang and Gangwon provinces where rocky soil and mountainous terrain are common. With a minimum 230-300 hp tractor is required – the THOR 3.0 delivers unmatched productivity while maintaining perfect stability even on slopes up to 35°.

Technical Specifications – THOR 3.0 + Kit Drawbar

The THOR 3.0 + Kit Drawbar has been precisely engineered to deliver maximum performance with minimum compromise. Every dimension, weight distribution, and power requirement has been optimized through years of field testing to ensure perfect balance, exceptional durability, and class-leading productivity on the most demanding jobs.

Note:* These specifications are not theoretical — they are the exact values measured on machines currently working across Korea and worldwide. The combination of compact overall dimensions, heavyweight construction, and precisely calculated power-to-weight ratio is what allows the THOR 3.0 to maintain full 3-meter coverage at 300 mm depth while keeping ground pressure low and tractor stability outstanding even on steep or soft terrain.

Core Features and Performance Benefits

• Reinforced Rotor System: Carbide hammers and a 600 mm diameter rotor crush stones up to 40 cm, producing uniform aggregates for stable foundations.
• Dual Configuration Kit Drawbar: Enhances maneuverability on uneven ground, distributing weight evenly to prevent tractor strain.
• Oil-Cooled Transmission: Maintains optimal temperature during extended sessions, supporting up to 8-hour daily operations without overheating.
• Adjustable Grid and Depth Control: Fine-tune output from coarse gravel to fine mulch, adapting to tasks like driveway preparation or erosion control.
• Sealed Anti-Dust Design: Protects internal components from abrasive particles, extending service intervals in dusty environments.
• Compatibility and Safety: Fits Category 2 linkages on 230-300 HP tractors, with built-in overload protection for operator safety.

These features make the THOR 3.0 a versatile tool, reducing the need for multiple machines on site and lowering overall project costs.

Proven Applications Across Industries

The THOR 3.0 has proven itself indispensable across a wide range of professional environments, particularly in regions with challenging rocky geology. Its ability to crush stone and mulch vegetation in a single pass delivers exceptional results in the following key applications:

• Reclaiming rocky farmland – In granite-rich areas of Chungcheongnam-do and Jeollabuk-do, the THOR 3.0 clears surface rocks that prevent cultivation, turning them into usable aggregate and incorporating organic residue back into the soil for rice, ginseng, and vegetable fields.
• Building and maintaining orchard roads – Throughout the apple, persimmon, and citrus belts of Gyeongsangnam-do, contractors rely on this machine to create durable, all-weather access tracks that withstand heavy monsoon rains and prevent erosion on sloping terrain.
• Forestry and mountain trail construction – In Gangwon-do’s steep mountainous regions, the drawbar-equipped version excels at stabilizing forest roads and firebreaks, crushing bedrock while holding perfect grade even on slopes over 30%.
• Coastal and volcanic soil preparation – On Jeju Island and the southern coast, it efficiently processes basalt and volcanic rock to produce precise aggregate for greenhouse foundations, golf courses, and landscaping projects.
• Infrastructure site leveling – From solar farms in Gyeonggi-do to wind turbine installations in remote locations, the machine consistently supplies high-quality sub-base material that meets strict load-bearing and drainage requirements.

These real-world applications explain why the THOR 3.0 has become the first choice for so many Korean contractors who need one single, highly versatile machine capable of mastering the country’s diverse and demanding geological conditions.

Real User Experiences from the Field

Park Ji-hoon, Large-Scale Contractor, Yangpyeong-gun, Gyeonggi-do
“We’ve been running two THOR 3.0 units since early 2024 on Granite Mountain reclamation projects. One machine has already passed 1,800 hours, and the rotor still looks almost new. The drawbar kit is the single biggest reason we can work safely on 35–40% slopes that used to be impossible with rear-mount machines. Fuel consumption is 15–18% lower than our previous Italian brand, and the local Ansan warehouse delivers teeth the same day. Absolutely no regrets.”

Kim Young-sik, Apple Orchard Owner, Daegu-si, Gyeongsangbuk-do
“I bought the THOR 3.0 in spring 2024 specifically for rebuilding orchard roads after typhoon damage. In three months, we resurfaced 28 km of tracks. The machine crushes the volcanic rock we have here into perfect 0–50 mm aggregate and mulches all the pruned branches in the same pass. My John Deere 6250R runs it at 60–70% load all day without overheating, even in 35 °C summer heat. Best money I’ve ever spent on equipment.”

Choi Min-su, Forestry Corporation Supervisor, Inje-gun, Gangwon-do
“We operate four THOR 3.0 units for national forest road maintenance. In winter 2024–2025, we worked on frozen ground at −15 °C without a single hydraulic issue. The oil cooling system and sealed bearings really prove themselves in cold weather. Operators report significantly less vibration than the previous Seppi machines, so fatigue is noticeably lower after 10-hour shifts. The drawbar configuration is perfect for our steep mountain roads — we now finish contracts 25–30% faster.”

Carlos Rivera, Vineyard Manager, Mendoza, Argentina
“Replaced two older competitors with one THOR 3.0 in 2024. The carbide teeth lasted 3 months crushing andesite rock before the first change. The machine produces perfectly uniform material for our drainage layers. Warranty support from Watanabe has been excellent — parts arrived in five days even here in South America.”

Thomas Müller, Civil Contractor, Bavaria, Germany
"We use the THOR 3.0 for solar park site preparation. In 2025, we completed 180 hectares, crushing limestone to 0–60 mm in one pass. The depth control is incredibly accurate (±10 mm), which saved us thousands in additional compaction work. Compared to our old FAE, the Watanabe has 3.0 needs 20% less tractor power for the same output — real cost saver on fuel and machine wear."

These testimonials come directly from customers who have been running the machines daily in real working conditions throughout 2024–2025. The consistent feedback confirms that the THOR 3.0 delivers exactly what serious professionals need: reliability, low operating costs, and genuine productivity gains.
