Comprehensive Gardening tools set tailored for professional gardeners and

The paddy field leveling and mud stirring machine is a three-point hitch type special soil preparation implement for paddy fields, driven by the power take-off of high-horsepower four-wheel tractors. It serves as the core equipment for paddy field soil preparation before rice planting. This machine integrates multiple working procedures including rotary tillage, soil crushing, stubble burying, mud stirring and land leveling. It can complete the full set of soil preparation work after paddy field soaking in one pass, replacing the traditional mode of repeated field entry for rotary tillage, harrowing and manual land leveling. It is widely used in large-scale rice planting bases, family farms and agricultural machinery cooperatives. Suitable for various paddy soils such as clay and loam, it meets the high-standard operation requirements for mud layer and field surface flatness of machine-transplanted rice and seedling throwing. The main frame of the whole machine is welded with thickened steel plates, adopting side transmission structure of gearbox and high-strength curved blade roller, equipped with rear leveling board. It features solid structure and stable operation. Meanwhile, the product is included in the agricultural machinery subsidy catalogue to lower procurement cost, making it a preferred agricultural equipment for cost reduction and efficiency improvement in modern rice cultivation.

1. Stubble breaking and grass burying: High-speed rotating mud stirring curved blades cut and break rice stubble and crop residues, completely burying crop stubble under the mud. Straws are fully returned to the field to reduce weed growth in the field, prevent floating straws from interfering with transplanting work and improve soil organic matter content.
2. Soil crushing and mud stirring: Break soil clods, fully mix soil and water to form uniform and fine mud layer with proper hardness, which ensures stable seedling standing during transplanting and reduces floating and lodging seedlings.
3. Field leveling: The machine is equipped with rear leveling device. It levels the field synchronously during operation to eliminate height difference of the field, keep the field surface height difference within a tiny range, ensure uniform water level in the field and save water and preserve soil moisture.
4. Integrated soil preparation: One-pass operation completes the whole set of processes including rotary tillage, stubble burying, mud beating and land leveling. It reduces damage to soil structure caused by repeated field entry of machines, alleviates soil compaction.

The whole machine frame is integrally welded with thickened high-strength steel, featuring strong torsion and shock resistance. It is not easy to deform or crack under muddy paddy field conditions and maintains high reliability in long-term operation.

It adopts reinforced gearbox side transmission structure with large transmission torque. Equipped with waterproof sealing design and built-in floating oil seal, mud can hardly enter the box, extending service life of gears and bearings.

The curved blades are made of wear-resistant alloy steel, undergoing quenching treatment, with excellent wear resistance and impact resistance. It can cut stubble and stir mud efficiently, reducing frequent replacement of blades.

Adjustable rear leveling board allows users to adjust leveling depth and mud layer thickness according to soil conditions and agronomic requirements, realizing flexible operation.

The three-point suspension connection mode achieves quick mounting and dismounting with tractors, convenient for field transfer and maintenance. The overall structure is optimized to reduce power consumption and lower tractor load.

The protective cover is tightly fitted to block mud splashing, protecting transmission components and operators, improving operation safety.

1. High operation efficiency. Multiple procedures are completed in one pass, greatly cutting operation time and labor cost. One machine can finish the soil preparation work of dozens of mu of paddy fields per day, which is several times higher than the efficiency of traditional separate operation.
2. Superior working quality. The fine and uniform mud layer formed after operation provides ideal growing conditions for rice seedlings. Flat field surface ensures consistent water depth, effectively raising survival rate of machine-transplanted rice seedlings.
3. Long service life and low maintenance cost. Key components such as frame, gearbox and blades are reinforced. The reliable sealing structure prevents mud corrosion, reducing failure rate and downtime.
4. Wide adaptability. It can adapt to different soil types and various field conditions. The adjustable leveling mechanism meets diverse agronomic demands of different rice planting modes.
5. Cost-effective procurement. Eligible for national agricultural machinery purchase subsidies, which directly reduces users’ investment cost. The machine saves fuel and labor in operation, bringing long-term economic benefits for large-scale planting users.
6. Simple operation and maintenance. Reasonable layout facilitates daily inspection, lubrication and blade replacement. Operators can master operation skills quickly with simple training.
