Machine construction

1. Three-point linkage

The massive suspension system serves as a supporting element of the mulching harrow. The solid tower of the three-point suspension system makes the machine durable and resistant to loads.

2. Subsoiler tine

The bent tips of the blades generate vertical pressure on the soil, causing a uniform lifting of the earth layer, known as the wave effect, without negatively affecting the soil structure.

3. Option for mounting cutting discs in front of the tine

Optionally, cutting discs can be mounted at the front of each tine to minimize soil disturbance and enable driving over crop residues.

4. Spring protection

Mechanical Non-Stop protection ensures comfortable operation by eliminating the need for part replacements. Rapid upward tilting and return of the tine upon encountering obstacles maintain the set working depth.

5. Adjusting the working depth

Step adjustment enables the subsoiler to maintain a consistent working depth.

6. Solid oversized machine frame

The solid frame construction is the most critical element of the cultivation machine. The substantial amount of steel used in its construction makes these robust tools capable of utilizing the high power of modern agricultural tractors, ensuring many years of operation on the farm.

7. Tillage roller

To precisely maintain the working depth and enhance the effectiveness of a single pass, the machine can be equipped with a tillage roller from the manufacturer's offerings.

8. Beam with OFAS 560 mm discs behind the roller

The harrow discs with 3D cushioning, used immediately post-harvest, eliminate weeds and stimulate volunteer crops to germinate for eradication in subsequent treatments.

9. Adjusting the working depth of the discs.

The working depth of the discs relative to the roller is regulated by a single adjusting screw.

10. Quality steel

Achieving a high-quality final product necessitates the use of superior metallurgical materials; therefore, in manufacturing the agricultural machine frame, we utilize fine-grained Swedish steels S500MC and S700MC.

11. Laser processing of sheets, tubes, and profiles

The application of laser techniques in the production of agricultural machinery facilitates precise cutting in high-quality, hard sheets, where conventional chip drilling methods are challenging and costly.

12. Steel shot blasting and powder coating

Proper preparation of machine parts combined with powder coating ensures a durable and robust coating. Additional maintenance and complicated care are unnecessary.

Subsoiler tine

The U 626 subsoiler tine features a blade designed for efficient soil loosening and lifting without disturbing natural layers. This component creates a "wave" effect, enhancing soil aeration and water infiltration while preserving organic matter without mixing it. The plough comes with a replaceable cover and is constructed from hardened boron steel. The chisel and undercutter form a single working element. The tine's angle of attack ensures smooth and trouble-free ground entry. Unlike V-shaped machines, the symmetrically arranged tines on the U 626 subsoiler, positioned on one crossbeam, provide more effective soil loosening across the entire crop width. The topsoil remains undisturbed, and plant residues stay on the surface, maintaining protection against erosion and adverse weather conditions.

Spring protection

The U 626 subsoiler is optionally equipped with a mechanical protection system featuring a double spring. If a tine encounters a stone, it tilts along with the leg, compressing the spring. Once the obstacle is cleared, the plough elements automatically return to their working position. Each tine independently reacts to obstacles, with the spring minimizing forces generated during collisions and enabling the component to immediately return to its precisely set working position. The spring protection of the tines in the subsoiler is included in the list of additional equipment.

Beam with OFAS 560 mm discs – ideal for stubble tillage equipment

Beam with OFAS discs behind the roller

For pre-mixing stubble behind the tillage roller, a single disc harrow beam with 3D shock absorption can be mounted. The disc protection system can move in all directions while avoiding obstacles. The overload system ensures optimal penetration, and the spring improves cultivation through vibration, maintaining disc cleanliness and consistency of work. This setup allows simultaneous deep soil loosening and delicate surface layer mixing with plant residues. Discs mounted in a single row behind the subsoiler roller gently mix the stubble into the top soil layer. This is beneficial in conservation agriculture systems for minimizing erosion, increasing water retention, and maintaining high soil biological activity and fertility. Attaching a single disc harrow bar to the subsoiler enhances integrated and efficient crop residue management and soil preparation, combining deep loosening with gentle stubble mixing in a single pass.

When to use a subsoiler? Applications in precision farming

Destiny

The subsoiler is engineered to break and loosen the soil to enhance its physical and biological properties. It loosens the layer of soil not reached by plowing, allowing better percolation and aeration, which fosters plant root development. Subsoiling reduces the depth of plowing for several consecutive years, resulting in significant fuel and time savings. It also moves fertilizers to deeper soil layers. This procedure is necessitated by water stagnation in fields during spring. For effective soil crumbling, subsoiling must be done when the soil is relatively dry. Excessive soil moisture leads to smearing rather than crumbling.

Best conditions for subsoiling – optimal timing

When should a subsoiler be used?

Soil undergoing continuous technological processing (ploughing, machine transport, harvesting) becomes increasingly compacted, preventing water penetration to lower layers. Excessive compaction leading to water stagnation indicates the necessity of a subsoiler to loosen deeper soil layers. Rolmako offers a comprehensive range of machines designed to address excessive water retention on the field surface efficiently. The robust and durable main frames are the hallmark of all Rolmako subsoilers. Utilizing these machines enhances the soil's microclimate by retaining more moisture and improving ventilation, resulting in better crop yields. The subsoiler's operation ensures water absorption into the soil, promoting healthy and stable crop growth. Rolmako subsoilers are available in multiple varieties, featuring various tine types and overload protection, with distinct supporting frame structures.

Benefits of subsoiling – better crop growth and erosion reduction

Advantages of subsoiling:

- Increased yields
- Improved root development
- Enhanced water management through better soil permeation and greater water retention
- Mitigation of fungal disease risks
- Potential for earlier sowing
- Decreased soil pollution
- Reduced pre-winter ploughing costs by shallowing
- Positive impact on future crop cycles

Rolmako machinery is made of premium Swedish steel S500MC and S700MC

Steel offering a competitive advantage

Increasingly larger and more powerful agricultural tractors subject the structural elements of agricultural machinery to significant stress, pushing them to their operational limits. Modern agricultural structures are expected to demonstrate high resistance to loads and an extended service life. Achieving a high-quality end product necessitates the use of superior-quality steel in production. Accordingly, we utilize high-quality Swedish fine-grained steels S500MC and S700MC, as well as carbon and boron steels for heat treatment and the wear-resistant Hardox. The use of these high-quality steel products ensures our agricultural equipment is highly durable and capable of operating at high speeds with high surface efficiency.
