Deep Tillage Machine 3S-1.4 – Heavy-Duty Subsoiler for Deep Soil Loosening & Preparation
Product Name: 3S-1.4 Subsoiler (深松机)
Suitable For: Deep soil loosening; hardpan breaking; compaction relief; drainage improvement; root zone deepening; moisture conservation.
Product Overview
The 3S-1.4 Subsoiler is a specialized primary tillage implement designed to address one of the most limiting factors in crop production: soil compaction. Over time, repeated field operations, heavy machinery traffic, and natural soil settling create dense layers (hardpans) beneath the surface that restrict root growth, limit water infiltration, and reduce crop yields. The 3S-1.4 is engineered to fracture these compacted layers without inverting the soil, preserving surface residue and soil structure while creating pathways for roots, air, and water.
Engineered for tractors in the 30-40 horsepower range, the 3S-1.4 is perfectly matched to compact and utility tractors commonly found on small to medium-sized farms. With a working width of 1400mm and 7 deep-tillage shanks, this subsoiler offers effective deep loosening in a compact, maneuverable package. At 280kg, it provides the necessary weight for deep penetration while remaining manageable for smaller tractors.

Detailed Features and Benefits
1. Category I Three-Point Linkage
The 3S-1.4 is equipped with a standard Category I three-point hitch, ensuring seamless compatibility with compact tractors in the 30-40 horsepower class. This universal mounting system allows for quick attachment and detachment, while hydraulic control enables precise adjustment of working depth directly from the tractor seat. The linkage design also allows the subsoiler to follow ground contours for consistent depth across uneven terrain.
2. Optimal Working Width
With a working width of 1400mm (1.4 meters / 55 inches) , this subsoiler offers effective coverage for small to medium fields:
-
Efficiency: The 1.4-meter span allows farmers to cover ground at a reasonable pace while targeting compacted layers.
-
Maneuverability: The width is well-suited for smaller fields and irregularly shaped plots where larger subsoilers would be cumbersome.
3. Deep Tillage Capability (up to 350mm)
The 3S-1.4's defining feature is its ability to work at depths up to 350mm (13.8 inches) :
-
Hardpan Breaking: At this depth, the subsoiler shatters compacted layers that restrict root growth and water movement.
-
Root Zone Deepening: Deep loosening allows crop roots to penetrate deeper into the soil profile, accessing additional moisture and nutrients.
-
Drainage Improvement: The fractures created by subsoiling act as channels for excess water, improving drainage in poorly structured soils.
-
Variable Depth: The 100-350mm adjustment range allows operators to match tillage depth to specific soil conditions and compaction layers.
4. Seven Heavy-Duty Shanks
The heart of the 3S-1.4 lies in its 7 deep-tillage shanks:
-
Shank Design: Each shank is engineered to penetrate compacted soil with minimal draft, featuring a narrow profile that reduces soil disturbance at the surface while fracturing deeply.
-
Replaceable Points: The shanks are fitted with wear-resistant, heat-treated points that can be replaced when worn, extending the implement's service life.
-
Spacing: The seven shanks are strategically spaced to ensure complete coverage across the 1400mm width, with overlapping fracture zones between shanks.
-
Shear Bolt Protection: Individual shanks are often protected by shear bolts that break if an immovable obstacle is encountered, preventing damage to the shank and frame.
5. Robust Construction (280kg)
Weighing 280 kg, the 3S-1.4 is durably built for demanding deep tillage:
-
Penetration Force: The substantial weight helps force the shanks into compacted soil, reducing the need for excessive hydraulic downforce from the tractor.
-
Heavy-Duty Frame: Constructed from high-strength steel to resist twisting and flexing during deep tillage operations.
-
Stability: The weight provides stability, keeping the implement at consistent depth even in variable soil conditions.
6. Conservation Tillage Benefits
Unlike moldboard plows that invert the soil, the 3S-1.4 uses a non-inversion tillage approach:
-
Residue Retention: Surface crop residue remains largely in place, protecting the soil from erosion and retaining moisture.
-
Soil Structure Preservation: The soil profile is fractured but not turned, preserving biological activity and soil structure.
-
Organic Matter: Surface organic matter remains near the surface, where it benefits soil health.
Ideal Applications
1. Compaction Alleviation
The primary application for the 3S-1.4 is breaking up compacted soil layers. Regular subsoiling (every 3-5 years) prevents yield-limiting compaction from developing.
2. Drainage Improvement
In fields with poor natural drainage, subsoiling creates channels that allow excess water to move through the profile, reducing waterlogging and improving crop growth.
3. Deep-Rooted Crop Preparation
Before planting deep-rooted crops such as sunflowers, corn, or tap-rooted vegetables, subsoiling ensures roots can penetrate deeply to access moisture and nutrients.
4. Dryland Moisture Conservation
In rainfed agriculture, subsoiling helps capture and store rainfall by improving infiltration and reducing runoff, making more water available to crops during dry periods.
5. Orchard and Vineyard Establishment
When establishing orchards or vineyards, deep subsoiling in planting rows ensures young trees and vines can develop strong, deep root systems.
Conclusion
The 3S-1.4 Subsoiler is a specialized but essential tool for farmers dealing with soil compaction. Perfectly matched to 30-40hp tractors, it offers an effective 1400mm working width, deep tillage capability down to 350mm, and the penetrating power of 7 heavy-duty shanks. At 280kg, it is robustly constructed to fracture hardpans while remaining manageable for compact tractors. For farmers seeking to improve soil structure, enhance drainage, and unlock their soil's full yield potential, the 3S-1.4 delivers results that pay dividends for years to come.
