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.

- 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

The standard tine with a 100 mm chisel can be replaced with a newer model with a width of 300 mm. The beam is equipped with two replaceable covers, and the entire assembly is made of hardened boron steel. The chisel, together with the side undercutters, constitutes one working element. The beam includes holders for the installation of drainage balls. The tine's attack angle allows for smooth and trouble-free entry into the ground. Hardened sleeves in the tine holders and beams prevent the holes from breaking. The working element is secured against overload with an M20 screw. In the version with hydraulic protection, a gas accumulator ensures smooth operation. The symmetrically arranged tines of the U 602 subsoiler, unlike V-shaped machines, allow for better loosening of the soil due to the positioning of the working elements on one beam. The soil is moved simultaneously over the entire width of the crop. The top layer of soil is not mixed, and plant residues remain on the surface, as before the subsoiler passed. This protects the cultivation surface against erosion and adverse weather conditions.

The U 602 subsoiler's simple and unique technical solutions ensure precise operation, user-friendly functionality, and high efficiency. In the version with hydraulic protection, each subsoiler tine is equipped with a hydraulic cylinder connected to an accumulator via cables. The accumulator maintains a specific force for the tine's release upon encountering an obstacle. When the subsoiler hits a stone, hydraulic oil flows to the accumulator, causing the cylinder to close and return to its working position after bypassing the obstacle. Hydraulic overload protection allows for adjustment of the tine's release force by simply increasing or decreasing the pressure. The large-capacity hydraulic accumulator absorbs all substantial impacts affecting the machine.

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.

The subsoiler features a coupling for integration with the cooperating machine. This configuration allows for subsoiling in conjunction with a disc harrow and other devices outfitted with a three-point tractor hitch. The machine depicted in the photos combines a subsoiler with a compact disc harrow, offering a working width of 3.0 meters and equipped with a heavy rubber roller. The combined machine weight is 1800 kg. The disc harrow roller ensures operational stability and maintains the predetermined depth of cultivation. The subsoiler loosens the soil beneath the plowing depth, while the discs handle post-harvest processing.

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.

Rolmako tillage machines distinguish themselves from competitors due to their superior weight. The company's development team designs agricultural equipment to endure the most challenging working conditions. Rolmako machines efficiently cultivate land in demanding regions worldwide without requiring additional loads. The substantial amount of steel in their construction makes these tillage tools robust, enabling the utilization of high-power modern tractors and ensuring long-term farm investment.

Extensive export experience has enabled us to craft an offer aligned with customer expectations. Numerous configurations and additional agricultural equipment options allow us to adapt the device to specific field conditions. Years of dedicated efforts by Rolmako employees in enhancing the company's products ensure we deliver the highest quality products to the most remote regions, where they have proven effective in diverse soil systems.
