Ultra-shallow cultivation concept

Cultivation technology is pivotal in mitigating soil water conservation challenges. The latest significant trend in soil water conservation is ultra-shallow cultivation, particularly for shallow stubble cultivation. Proper soil cultivation is the cornerstone of the success of subsequent crops. Ultra-shallow cultivation, which undercuts the entire cultivated profile at a depth of just 2-5 cm, effectively interrupts water evaporation and rapidly initiates the emergence of scattered weed seeds and self-seeds on the soil surface. Interest in increasingly shallow post-harvest cultivation is growing annually, as it only desiccates the shallowest soil layer.





Corrugated SpeedCutter disc

Designed for ultra-shallow cultivation of 2-5 cm at a speed of 20 km/h. The refined geometry of the disc shape enhances cultivation possibilities and improves results under challenging conditions with rape stubble, cover crop shredding, and cereal stubble post-ploughing. The new shape of the disc harrow's working element increases area efficiency through higher working speeds, meeting the expectations of demanding farmers by achieving excellent cultivation effects at minimal soil processing costs. The wavy disc provides highly aggressive cultivation at shallow depths, making it the most effective disc cultivation component currently available for stubble work.













A new generation of multifunctional tillage implements

The SpeedCutter disc harrow design features a robust frame with an optimal 90 cm spacing between the disc rows and an optimized angle of attack for the working elements, enabling effective performance in both stubble conditions and seedbed preparation. The harrow supports operation at greater depths, making it a versatile tool, though this capability is not always required. Due to its shallow cultivation, the discs process less material than traditional cultivation discs, leading to reduced fuel consumption and increased working speed. Wavy discs deliver optimal results at speeds between 15-20 km/h.

SpeedCutter disc designed for maximum performance

The SpeedCutter disc harrow stands out primarily due to a new type of working element. The traditional disc has been replaced here with a wavy-structured disc. The design of the disc arm has been changed, which in the new variant allows for full utilization of all the advantages arising from the use of the wavy disc. The length and angle of the disc arm have been developed based on numerous trials conducted in various conditions, from sandy fields through fields with a large amount of post-harvest residues and cover crops to soils with very heavy and moist earth.





Crossboard drag

The drag is constructed from hardened springs and bent working tips. Positioned ahead of the disc section, it breaks up clods and levels the field, creating an optimal surface for sowing. The harrow is effective on stony fields as it does not bring stones to the surface. For challenging conditions, an optional stabilizing beam can be mounted to connect the working elements into a unified system for enhanced leveling. When a hard crust forms on the field surface, an aggressive skid with DoubleKnife tines is recommended.





Finger comb beam

The tool, placed between the rows of two disc sections, has adjustable working height and angle of inclination. It controls the flow of soil with mixed organic residues and improves the distribution of stubble residues over the entire field surface. The finger weeder operates without direct contact with the soil, retaining the soil, and allowing the rear disc section to work freely without issues dealing with a large amount of soil. The weeder can additionally be mounted between the rear disc beam and the finishing roller, thus regulating the flow of the cultivated mass onto the finishing roller.





Spring comb beam

The manufacturer optionally installs a beam with a spring comb behind the disc section, ensuring the straw is evenly spread across the field's surface, thereby preventing areas of high straw accumulation that hinder proper cultivation. Uniform straw distribution is crucial, as it ensures consistent development conditions for the next crop across the entire field. The spring comb is an effective tool that enhances cultivation, offering optimal starting conditions for sown plants.





APV aftercrop seeder

We equip our cultivation machines with catch crop seeders in partnership with specialists from APV, who provide a wide range of catch crop and fertilizer seeders. The complete product range and available accessories can be found on the manufacturer's website (https://www.apv-polska.pl). Utilizing APV catch crop seeders on Rolmako cultivation machines reduces unnecessary travel. APV devices ensure precise spreading of catch crops and subsowing, even in the smallest doses.





Tillage rollers

Kneading, compacting the soil, crushing clods, and leveling the field surface are the final stages of cultivation, performed by the rear roller following the working tools of the cultivation machines. The selection of the appropriate cultivation roller significantly impacts the entire work process and the functionality of the cultivation machine. At Rolmako, we offer a variety of cultivation rollers that differ in shape, material, external diameter, weight, and, most importantly, cultivation purpose. The choice of roller depends on the soil type and the desired cultivation outcome. Rolmako provides expert advisory services to ensure proper adjustment of the cultivation machine to the working conditions.

Origin of the SpeedCutter project

Achieving a clean field post-harvest is challenging with traditional cultivation tools. Planting seeds too deeply often causes prolonged dormancy, potentially lasting years, and interfering with subsequent crops, thereby reducing yield potential and increasing cultivation costs. Many weeds resist chemical control. In designing the new SpeedCutter disc harrow, our focus was on solutions that allow ultra-shallow cultivation to enhance field hygiene significantly. Volunteer emergence benefits from exposure to light and air, which occurs efficiently when seeds remain in the top layer. By working in alignment with plant biology, the profitability of crops is improved through cost reduction. The SpeedCutter harrow's concept involves less diesel fuel usage, faster volunteer emergence, reduced chemical dependence, and enhanced fragmentation of crop residues, accelerating organic matter decomposition in the field.





Maximum lifespan of disc bearings

The elimination of hub maintenance requirements minimizes maintenance needs and conserves time. Standard hubs can be substituted with SKF original maintenance-free hubs, offering three times the service life of other solutions. SKF quality ensures enhanced reliability, increased efficiency, and reduced operating costs. The service life of SKF hubs is substantially higher than that of conventional bearings, achieving this with relatively low ownership and operating costs. Composed of 100% bearing steel, the hub optimizes machine uptime and reduces agricultural machinery service costs.





Modern construction

The three-part frame of the machine facilitates better weight distribution, with the wings of the disc harrow being lighter. This design allows for the repositioning of the middle roller, enabling the rollers to overlap. Unlike rollers mounted in a single line, this configuration completely eliminates the potential for blockages. Placing the axle in front of the tillage rollers offers several advantages, including the ability to mount the rollers in a tandem system and improving the machine's performance on roads and in the field. The entire series of Rolmako U 652 disc harrows is designed to work with high-power tractors, delivering optimal performance at high working speeds.





LongLife rubber shock absorber

Each disc is independently mounted to the frame using a 40 mm x 180 mm rubber shock absorber, ensuring consistent maintenance of the working depth, an aggressive cultivation effect, and protection against damage. Rubber spring elements allow optimal adjustment of the recessed discs to the soil contours. The rubber rollers prevent sudden impacts with their extended shock absorption path. This ensures the safety of the disc harrow frame and maintenance-free overload protection while maintaining the set depth.





Adjustment of the row of disc

The front disc beam has a shift adjustment, enabling modification of the disc position relative to the rear working section. Adjusting the disc row settings proves beneficial at later stages of operation, as it compensates for reduced disc diameter resulting from extensive use. This adjustment maintains optimal working parameters despite disc wear.





Hydraulic drawbar

The disc harrow, equipped with an optional hydraulic drawbar, offers an additional function allowing for quick and gentle turning in the field using the intended cultivation rollers without the need for the machine's road wheels. The hydraulic drawbar, featuring an eye for the lower tractor hitch, simplifies connection to the tractor, increases each disc's pressure, and provides excellent stability during cultivation work and travel to the field. The optional drawbar is available with a fi 50 eye or a K80 ball hitch from Scharmüller. The drawbar with a fi 50 eye facilitates close attachment next to and below the tractor's rear axle, ensuring a reliable pulling point and improved energy transfer.









Supporting wheels

Wide front support wheels deliver exceptional control over working depth, enhancing stabilization and offering additional support to relieve the three-point tractor suspension system. The large wheel diameter ensures smooth operation on uneven fields, guarantees precise performance with wide machinery, and positively impacts cultivation quality by stabilizing the machine during operation.





Hydraulic adjustment of working depth

Hydraulic depth adjustment ensures optimal user comfort and significantly facilitates setting work parameters. The operator-friendly hydraulic adjustment of working depth is achieved using spacer clips on cylinders. This option is ideal when frequent changes in the machine's working depth are required.





Bearing units of the roller

By incorporating maintenance-free bearings into the tillage rollers, we minimize the required machine maintenance time. The ductile cast iron housing is four times more durable than its grey cast iron counterpart. The combination of top and internal sealing offers superior protection for agricultural use. Rolmako prioritizes the smallest machine elements in every project, significantly impacting maintenance time and reducing the costs and duration of agricultural equipment inspections.





Various configurations available

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.









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.









Oversized agricultural structures

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.









Transport carriage

Trailed disc harrows come with a hydraulic drive system that lifts during cultivation, adding extra weight to the harrow. Its placement in front of the tillage roller is crucial as it shifts the center of gravity toward the tractor, enhancing weight distribution. The disc harrow can operate at speeds up to 15 km/h, efficiently leveling the field. Road transport is safer since the machine's wheels bear most of the pressure, significantly reducing the load on the tractor's lift.
