4USJ-1500 Stone Picker

This 1.5m-wide trailed stone picker (Model 4USJ-1.5) is a tractor-towed land-clearing machine, designed to efficiently collect stones, debris, and clods from soil. It features an adjustable working depth (100–350mm) and a 1m³ capacity collection box, paired with a chain conveyor system that separates and transports stones to the storage bin. Compatible with tractors of 100HP and above, it is ideal for large-scale land preparation tasks to improve soil usability and operational efficiency.

1. Before operation, inspect the tractor hitch, hydraulic connections, and chain conveyor for damage or loose components.
2. Adjust the working depth according to soil conditions; avoid exceeding 350mm to prevent excessive resistance or equipment damage.
3. Do not operate on rocky, concrete, or asphalt surfaces to protect the chain and digging components from wear or breakage.
4. Regularly empty the collection box when full to avoid overloading and maintain stable traction.
5. After use, clean soil and debris from the conveyor and collection box, and lubricate the chain and bearings to prevent rust.
6. Secure the machine with a safety pin during transportation to avoid shifting or collision.

• Efficient Clearing: 1.5m working width covers a wide area per pass, reducing the time and labor required for land clearing.
• Adjustable Depth: Working depth can be set from 100mm to 350mm, adapting to different soil layers and stone distribution.
• Large Storage Capacity: 1m³ collection box minimizes the frequency of unloading, improving continuous operation efficiency.
• Strong Compatibility: Towed design works with 100HP+ tractors, making it suitable for both small and medium-sized farms and construction sites.
• Durable Construction: Heavy-duty steel frame and wear-resistant chain components ensure long service life in harsh working conditions.
• Smooth Conveying: The chain conveyor system gently transports stones without damaging the soil structure, preserving topsoil quality.

• Agricultural Land Improvement: Clearing stones from farmland to optimize soil structure, enabling smoother planting, seeding, and irrigation.
• Construction Site Preparation: Removing rocks and debris from foundation areas, roadbeds, and building sites to ensure safe construction.
• Orchard & Vineyard Maintenance: Cleaning stones from planting rows to protect farm machinery and improve root growth conditions.
• Coastal & Beach Cleaning: Removing rocks and debris from sandy beaches to enhance safety and aesthetics for tourists.
