Tractor Stone Rock Crusher Mulcher – THOR-3.0
A PTO tractor-mounted rock/stone crusher (also known as a tractor-mounted rock/stump crusher) is a heavy-duty, multi-functional workpiece driven by the tractor’s power take-off shaft (PTO). It is designed for the efficient removal of stones, stumps, tree roots, hard soil, and construction debris from the ground. It can complete crushing and leveling in one pass, laying a solid foundation for subsequent tillage, paving, or ecological restoration.
Overview
The THOR 3.0 is a PTO tractor-mounted stone crusher designed for high-intensity land clearing and foundation pretreatment. Its 3-meter wide working width and 2800 kg weight give it powerful crushing capabilities, efficiently handling hard rock, tree stumps, and concrete debris in large farms, mining roads, and infrastructure projects.
The equipment is compatible with tractors down to 230 hp, operates at a stable speed of 3 km/h, and ensures uniform crushing depths up to 50 cm even in complex terrain. With its robust structural design and high-torque rotor system, the THOR 3.0 plays a crucial role in modern agricultural reclamation, rural road construction, and degraded land reclamation—transforming "uncultivable land" into efficient farmland or stable roadbeds, helping global customers improve operational efficiency, reduce overall costs, and promote sustainable land use.

Advantages
💪 Powerful Crushing Force
Equipped with a high-torque rotor system and tungsten carbide carbide blades, it efficiently crushes hard obstacles such as rocks, tree stumps, and concrete blocks, easily handling the most demanding working conditions.
⚙️ Flexible and Adjustable Depth
The working depth can reach up to 50 cm, adjustable as needed, precisely matching different operational requirements whether for shallow obstacle clearing or deep soil reconstruction.
🛡️ Superior Durability
Key components are made of Hardox® high-strength wear-resistant steel, offering impact and wear resistance, significantly extending equipment life and reducing maintenance and replacement costs.
🚜 Wide Compatibility
Perfectly compatible with mainstream tractor brands of 230–500 hp, including John Deere, Case IH, New Holland, and Kubota, ready to use immediately without additional modifications, allowing for rapid deployment.
Application Scenarios
🌾 Agriculture
Efficiently reclaims new farmland containing rocks and tree roots; breaks up hardened soil layers, improving soil structure; provides a flat, unobstructed working foundation for large-scale mechanized planting of corn, soybeans, sugarcane, etc.
🏗️ Infrastructure Construction
Suitable for preliminary foundation treatment of projects such as rural roads, mining area transportation channels, border highways, photovoltaic power stations, and wind farms; pulverizes rocks and construction debris on-site to form a stable base layer, significantly shortening the construction period and reducing filler costs.
🌿 Ecological Restoration and Land Regeneration
Assists in forest regeneration and firebreak construction, quickly clearing shrub stumps; implements land reclamation in abandoned mining areas, eroded slopes, or desertified areas, removing stubborn obstacles and creating conditions for vegetation restoration.
How to Install Tractor-Mounted Stone Rock Crusher
- Prepare the tractor: Park on level ground, turn off engine, lower 3-point hitch (Category 2), and engage parking brake.
- Attach to hitch: Lift the crusher into position, align with lower link arms, and secure with hitch pins and clips.
- Connect PTO shaft: Slide the driveline onto the tractor’s PTO output, lock in place, and ensure the safety guard is installed.
- Hook up hydraulics (if equipped): Connect hoses to the tractor’s two rear remote valves for depth or side-plate control.
- Final checks: Grease all fittings, torque bolts, start at idle, and test PTO engagement and lift functions slowly.
✅ Always verify compatibility with your tractor (230–500 HP models like John Deere, Case IH, Kubota).

Real Customer Case Studies
🇧🇷 Brazil – Soybean Field Land Clearing
Customer: Carlos Mendes
Land: 🇧🇷 Brazil (Mato Grosso State)
Farm Size: 2,000 hectares
Challenge:
While clearing native Cerrado land for soybeans, Carlos encountered dense basalt boulders (15–40 cm in diameter) and deep-rooted hardwood stumps. Conventional plows kept breaking, and manual rock removal cost R$900/ha—delaying planting and threatening his entire season.
How They Found Us:
Carlos saw a live demo of our stone crusher at Agrishow 2023 (Brazil’s largest agri-trade show) and arranged a field trial through our local dealer.
Our Solution:
We recommended the STAB FRS-250 PTO Stone Rock Crusher, mounted on his Valtra T330 tractor (330 HP), set to a 45 cm working depth with tungsten-carbide stump-shredder teeth.
Results:
- Cleared 1,800 ha in 3 weeks (vs. 4 months originally projected)
- Reduced clearing cost to R$240/ha
- Achieved flawless, uniform soybean emergence
Customer Testimonial:
“This machine didn’t just save my planting season—it saved my business. Before, we called this land ‘impossible.’ Now it’s our highest-yielding field. I’ve already ordered a second unit for next year.”
🇮🇳 India – Sugarcane Soil Improvement
Customer: Arun Desai
Land: 🇮🇳 India (Maharashtra State)
Farm Size: 280 acres
Challenge:
Arun’s sugarcane fields sat on the Deccan Plateau, riddled with weathered basalt fragments (“murum”) that caused soil compaction and poor root development. Germination rates averaged just 65%, dragging yields far below regional potential.
How They Found Us:
After watching a YouTube video titled “tractor stone crusher for sugarcane field,” Arun contacted our authorized dealer in Pune for an on-farm assessment.
Our Solution:
We supplied the STAB FRS-225, compatible with his Mahindra 775 DI tractor (280 HP PTO), operating at 30 cm depth to break up surface stones and integrate them into the topsoil.
Results:
- Soil became looser and more moisture-retentive
- Germination rate rose to 91%
- First-season yield increased by 18 tons/acre
Customer Testimonial:
“We used to burn crop residue and struggle with stones every season. Now, the crusher turns problems into soil. My neighbors are all asking where I got this ‘magic machine’!”
🇺🇸 USA – Organic Farm Reclamation
Customer: Emily Carter
Land: 🇺🇸 United States (Missouri)
Farm Size: 400 acres (former limestone quarry)
Challenge:
Emily purchased a decommissioned quarry to convert into a USDA-certified organic soybean farm. But the site was littered with rubble, concrete chunks, and even rebar—making conventional tillage impossible and off-site disposal prohibitively expensive and unsustainable.
How They Found Us:
While searching for “organic land reclamation equipment,” she discovered our product through an agricultural forum and scheduled a live demo with our Midwest distributor.
Our Solution:
We deployed the heavy-duty STAB HP-250, mounted on her Case IH Steiger 500 (500 HP), running at full 50 cm depth to pulverize all debris in place—no hauling, no fill needed.
Results:
- Earned USDA Organic certification in Year 1
- Achieved 52 bushels/acre soybean yield—on par with regional averages
- Zero waste, zero external inputs: fully regenerative process
Customer Testimonial:
“People said this land was dead. But your crusher gave it life again—without trucks, without waste. It’s not just a tool; it’s part of our regenerative story.”
