The special frame with a two-row design enables heightened intensity, resulting in improved breakage of excessively compacted lower soil layers. The working elements in the front section initiate soil loosening for the rear section tines, thereby reducing the force required by the subsequent beam's working elements. Additionally, the rear tines' deflection is directed opposite to that of the first row, providing double loosening with an enhanced groove for water infiltration and drainage. The Rolmako U 619 subsoiler is compatible with tractors ranging from 240 to 400 HP. It is available in working widths of 3 and 4 meters, with 12 and 16 working elements, respectively. The U 619's maximum working depth is nearly 45 cm, and the recommended working depth is approximately 10 cm below the target soil layer. The minimum required power per tine is up to 30 HP, depending on the working depth and local soil conditions. The two-row subsoiler, equipped with Michel tines, requires less power due to the positioning of tines one behind the other, reducing the force needed for the rear tine to pass through the opening made by the preceding working element. The two-beam subsoiler ensures excellent operational stability and ideal dispersion of mechanical stresses. The U 619 subsoiler is designed to meet all user requirements, with adjustable tine spacing that allows adaptation to any agricultural tractor.
Two rows of tines, double loosening efficiency
The concept seeks to optimize water distribution to enhance plant root development
The U 619 subsoiler is specifically engineered to enhance water absorption efficiently in a single pass. Its compact design featuring two rows of Michel tines allows for soil loosening without deconstruction. The working depth of the Rolmako U 619 subsoiler is primarily adjusted via the tractor's three-point linkage; thus, the optional rear roller is recommended. This tillage roller, available in various types from the Rolmako range, provides additional soil compaction, helps maintain working depth, breaks up clods, and levels the field surface. The Twin Disc double disc roller augments the machine’s function by cutting and mixing, leaving the soil optimally prepared for subsequent cultivation. The Rolmako U 619 subsoiler ensures soil division at deeper layers, mitigates soil compaction, and positively impacts root growth. Designed to meet the demands of hard soil and modern tractors, the machine features numerous reinforcements on the frame and a robust three-point suspension system, ensuring durability and load resistance. By using the Rolmako U 619 subsoilers, improved root development, air and mineral fertilizer permeability to deeper soil layers, and enhanced access to air and water are achieved, simplifying plant rooting in loosened soil.
Enhanced root development, improved air and mineral fertilizer permeability
Utilizing a subsoiler with a curved Michel tine is recommended for compact soils that require enhanced porosity while maintaining an intact surface structure. This working element improves soil circulation and oxygenation, promoting root growth and plant development. Unlike traditional cultivators with straight tines, the subsoiler with a Michel tine breaks up the soil with less resistance, preserving the ground surface. Furthermore, using a subsoiler with a curved working element can reduce water demand by approximately 10% if additional field irrigation is applied. For optimal results, employ a subsoiler with a bent Michel tine on loose soil (neither extremely dry nor wet). The soil structure created by this subsoiler reduces the need for annual subsoiling. Subsequent procedures will only be necessary when the soil becomes too compacted for sowing or water pools form due to compacted paths under tractor wheels. This device is ideal for no-plough cultivation technology.

Michel's deflected tine
Rolmako offers a range of subsoiling machines with various versions of working elements. MICHEL type tines equip subsoilers with the symbols U 608 (MICHEL small version), U 614, and U 619. The new series of subsoilers features optimized geometry of the working elements, enhancing soil substrate loosening without negative effects and positively impacting the soil structure. The subsoiler tine, with its curved structure, is specially designed for smooth, gradual soil penetration. Offering minimal resistance, it effectively loosens the soil, ensuring adequate access to water and air for crops. The curved tine shape allows better soil penetration and breaks deep hard coatings, improving moisture retention. The undercut soil is slightly lifted and then returned to its place, achieving better loosening compared to classic straight tines. The tine shape ensures uniform surface cutting over the entire working width. The double-sided chisel extends the working element's service life. Made of high-quality boron steel with a hardness of 50 HRC, the tines are designed for optimal soil loosening efficiency while maintaining low power requirements. The variety of combinations of Rolmako subsoilers with the MICHEL tine makes them the most comprehensive offering on the market.
Twin Disc double disc roller
Optionally, the machine can be equipped with a rear roller, enabling control over cultivation depth. Traditional rollers, such as Pipe or Packer, are available as well as an aggressive roller with two rows of 470 mm wavy discs. These discs cut crop residues, crush clods, cover stubble material with soil, and level the field surface post-subsoiling. This section enhances soil condition and improves the efficiency of the subsoiler's performance. Ultimately, the recommended roller is the Twin Disc double disc roller, which effectively breaks clods, loosens the soil surface, cuts crop residues, and stabilizes the machine’s operation.
The primary properties
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.

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 the U 614 subsoiler 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.
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
