Tractor Stone Crusher for Agroforestry Systems Features
The AH Tractor Stone Crusher adapts to the most powerful tractors (from 280 to 400 hp), with a maximum operating depth of 25 cm and the ability to crush stones up to 50 cm in diameter. It is also equipped with a new side-scraper system to limit side wear, adjustable skids, as well as interchangeable protection chains. The three models available (with working widths of 200, 225, and 250 cm) make it perfect for different jobs, particularly to treat soils with large quantities of moving stones.

Benefits of Tractor Stone Crusher for Agroforestry Systems
- Improved Land Use Efficiency: In agroforestry systems combining trees, crops, and pasture, this stone crusher removes stones and debris without damaging tree rows or pasture. By leveling the land and breaking up rocks, it improves planting, grazing, and tree-growing areas.
- Enhanced Soil Health and Improved Tree Survival: Breaking up stones increases soil contact area, improves root penetration for trees and crops, and reduces the risk of damage to planting equipment or tree roots.
- Reduced Maintenance and Equipment Wear: By removing large stones before planting or establishing pasture, tractors, tree planters, and other equipment are protected from stone impacts, reducing maintenance costs and downtime.
- High Terrain Adaptability: Designed for agroforestry systems (intercropping, forestry-farmland systems) and mixed forestry-crop systems, this machine can operate between tree rows, around pasture, and on uneven terrain, supporting multi-purpose land systems.
How does a tractor stone crusher work?
- Accessories and Power Take-Off Shaft Drive: The stone crusher is mounted on the tractor’s three-point suspension or other compatible mounting position and is driven via a power take-off shaft, transmitting power from the tractor to the machine.
- Rotor Impact System: Inside the machine, a high-speed rotor equipped with fixed or replaceable teeth impacts rocks and stones, crushing them into smaller fragments and mixing them into the soil.
- Depth and Width Adjustment: The operator can adjust the working width and depth according to the agroforestry terrain—for example, shallow tillage to avoid tree roots, but sufficient to break rocks. Patterns vary depending on the tractor size and stone load.
- Soil Mixing and Leveling: After crushing, the stone is evenly distributed, the soil is leveled, forming a suitable seedbed for crops or pasture growth, and providing safe soil for tree growth.
- Post-Processing: The machine can be used in conjunction with a harrow or roller for surface treatment, ensuring the land is ready for planting, grazing, or afforestation in an agroforestry system.
How to Choose the Right Tractor Stone Crusher?
- Tractor Power: Check if the machine’s horsepower matches your tractor’s. For light agroforestry terrain, 70-150 horsepower may be sufficient; for heavier stone loads, consider higher horsepower.
- Working Width and Row Spacing: Match the working width to the spacing of tree rows or pasture access in your agroforestry design to avoid damage to trees or shrubs.
- Crushing Depth and Stone Load: Assess the size and distribution of the stone. For deeply buried stones, choose a model with a greater penetration depth. For models with depths of approximately 20 cm or more, refer to the manufacturer’s specifications.
- Rotor/Cutter Configuration: Look for a machine equipped with a durable rotor and cutters suitable for agroforestry soils (shallow, stony, root-rich areas). Ensure parts are easy to replace and maintain.
- Service and Parts Support: Especially for agroforestry systems that combine trees, pasture, and crops, choose a supplier with strong after-sales service, spare parts supply, and local service capabilities to minimize downtime.
Opiniones de clientes
“In central Italy, we implemented a mixed-planting system combining trees, crops, and pasture, using a tractor-mounted stone crusher to clear the rocky paths between tree rows and pasture access. It easily handled surface stones without damaging young olive trees, and we immediately saw improvements in soil texture and equipment wear.”
— Client: Manager of an agricultural and forestry farm in Tuscany, Italy
“We converted an old pasture into a mixed-planting system, combining tree planting and hay production. This machine removes large stones and levels the land in one operation; our planting team reports that the equipment is safer to use and the ground is smoother.”
— Client: Tree and pasture grower in Piedmont, Italy

Preguntas frecuentes
Q1: Can this tractor stone crusher operate in tree‑row spaced agroforestry systems?
A: Yes. The machine is designed with adjustable working widths and shallow working depths, making it compatible with tree‑row spacing in agroforestry systems without damaging existing trees.
Q2: What is the typical tractor horsepower needed?
A: For agroforestry use, tractors in the range 280‑400 hp are often sufficient. If the field has heavy rocks or a wider width machine is needed, higher horsepower tractors will be required.
Q3: How deep can the machine crush stones?
A: Depending on the model and soil conditions, many machines crush stones to depths of up to 25 cm. Always check model specifications for exact depth capabilities.
Q4: Will the machine disturb tree root systems or soil structure?
A: When correctly configured, the machine is used outside the main root zone of established trees and provides soil mixing without major root disruption. It improves soil conditions rather than disrupting them.
Q5: What kind of maintenance is required?
A: Regular inspection of rotor teeth, replacement of wear parts, lubrication of bearings, and checking the three‑point linkage are recommended. Use the manufacturer’s maintenance schedule to ensure long‑term reliability.
