Rolling is a critical agricultural procedure that significantly impacts crop quality and subsequent harvest. Rollers for field leveling and clod breaking, regardless of the type of rings installed, are widely used machines with functions and advantages appreciated by all farmers. Growers aiming to maximize profits should include them in their essential equipment. Designers focused on the seamless unfolding and folding of rollers for operation and transport, ensuring smooth usage with a single hydraulic cylinder mounted on the machine's drawbar. The design minimized the necessary hydraulic control, making the machine user-friendly and efficient. The terrain copying system ensures optimal weight distribution across all sections of the roller, guaranteeing uniform contact with the surface under all conditions and across the entire working width. Rolmako uses high-quality materials, especially in areas subject to constant wear, primarily on the rollers, ensuring the device's long service life. Rolling also offers an excellent opportunity to clear the field of stones. Optional equipment includes containers for stone collection. The 9.4 m wide roller features tandem axles.
These are not ordinary rollers but a valuable machine and a worthwhile investment
The purpose of the rollers depends on the selection of the cultivation ring
Suitable for a wide range of soil types, from light, sandy soils to heavy, wet, and sticky clay soils. Adaptable to all customer requirements. Rolmako offers four types of rollers for various applications: Cambridge for pre-sowing cultivation, Crosskill for crushing clods, a steel ring roller for use behind a stubble cultivator, and Campbell for soil compaction after plowing. Cultivation rollers can be integrated with other machines (cultivator, disc harrow), reducing the number of passes to a minimum. All working elements of the rollers are made from ductile cast iron GGG50. The 600 mm diameter steel ring roller effectively compacts soil and crushes clods. Its aggressive profile cuts and presses crop residues into the ground. The roller rings are made from abrasion-resistant material (hardened boron steel). Their smooth surface prevents soil and straw from sticking, even in humid conditions. Orion rollers are used for cultivating soil and grasslands. They are ideal for pre-sowing cultivation. On grasslands, the Orion roller stimulates grass tillering, rolls for sowing, and cares for existing resources. It is also used for stubble cultivation, supporting the decomposition of post-harvest mass. This roller is effective for cultivation when combined with a cutting knife roller.
Universal rollers provide excellent cultivation results
Rollers for field leveling and clod breaking are machines attached to the tractor using a two-point hitch, commonly known as the universal beam. The heavy frame of the roller, constructed of 200x100x10 mm and 200x100x8 mm profiles, ensures optimal pressure on the ground. A wide selection of rings allows for choosing appropriate rollers based on the soil type. Optimal compaction is achieved along the entire working width of the roller, even on bends and uneven terrain. The Rolmako roller system maintains constant pressure across the entire working width, allowing each section to operate independently. The terrain copying system ensures the rollers maintain optimal soil contact, even in difficult conditions. Springs transfer weight to the side sections. The Crossboard hydraulic drag is available as an option. The standard 45x10 mm spring with a 100 mm skid can be replaced with a reinforced version featuring an 80x10 mm spring and a 150 mm wide skid, which can also be equipped with a stabilizing beam. Rolmako rollers are known for their simplicity, operational reliability, and low service and maintenance requirements. The machine is user-friendly, with automatic locking for transport via a spring-loaded latch and release by a single-acting hydraulic cylinder. Preparing the ground before sowing or rolling after sowing can be accomplished with a single Cambridge roller.

Most frequently chosen accessories
Cultivation tools
Cambridge roller
The Cambridge roller, employed before sowing, levels the surface, breaks up furrows, and refreshes soil structure. It can also be utilized post-sowing. This operation enhances seed emergence uniformity and accelerates vegetation. Cambridge rollers feature a self-cleaning mechanism that ensures efficiency and reliability. They are ideal for field work and grassland applications. The roller compacts the soil, improving seed germination by creating a friable structure and optimal consolidation. Cambridge rollers are particularly effective for pre-sowing soil preparation, clod crushing, and surface leveling. Post-sowing, they further improve the regularity of plant emergence and accelerate vegetation.
Crosskill roller
After the machine equipped with Crosskill rings passes, the soil has a loose structure and is resistant to surface crust formation. The rings effectively break up clods and do not get blocked by soil adhesion. After the machine passes, the ground is heavily crushed. The Crosskill roller, with its narrow gap between the rings and special profile, is particularly suitable for medium and heavy soils. It ensures good compaction with a low risk of sticking. Crosskill excels at breaking up lumpy soil and leaves a strip with a loose structure, preventing crust formation. The roller is equipped with a scraper system that cleans the spaces between the rings.
Roller of steel rings
The 600 mm diameter steel ring roller efficiently compacts the soil and crushes clods. The aggressive ring profile cuts and presses crop residue into the soil. The roller rings are made of abrasion-resistant material. Their smooth surface prevents sticking with soil and straw, even in wet conditions. The steel ring roller supports the function of stubble cultivators and disc harrows. When working in stubble, it can be connected to a disc harrow using a coupling. The roller discs effectively crush crop residue in the field. The steel ring roller is equipped with a cleaning beam with scrapers made of HARDOX steel. This product offers the highest resistance to abrasion and overloads. The solution is economically justified on large cultivated areas.
ORION prismatic roller
ORION rollers are highly effective for post-harvest cultivation, accelerating the decomposition of straw and crop residues. The prismatic roller's profile is specifically designed for pre-sowing cultivation, featuring tines that minimize soil adherence and ensure optimal soil loosening for sowing. The sharp tines provide a reliable substrate for seed nesting. Pre-sowing cultivation requires effective leveling, crumbling, and proper soil compaction. The conical rings primarily used offer the advantage of having fine, compacted soil underneath and loosened, lumpy soil on top. This roller is ideal for grassland care as it does not damage plants or disrupt sown seeds. During operation, the roller self-cleans efficiently through the transverse movement of the rings relative to each other. ORION rollers are designed to improve soil structure, level fields, and break up clods. The prismatic roller, made from special castings, minimizes soil adherence and prepares an excellent substrate for sowing seeds. Additionally, these rollers facilitate the decomposition of straw and crop residues and promote the germination of scattered and weed seeds.
Campbell roller
The soil after sowing ploughing is too loose to allow for pre-sowing cultivation and immediate sowing. Due to increasingly shorter agrotechnical deadlines, it is thus necessary to compact it, which can be done efficiently and cost-effectively using Campbell compacting rollers with diameters of 560 mm or 700 mm. Campbell wheels are designed for standard compaction after ploughing. With a roller diameter of 560 mm, the significantly higher number of rings per meter results in more intense compaction.
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.
The primary properties
Roller folding and unfolding system
Rolmako is a company renowned for designing and producing tillage machines that are both ingeniously constructed and among the heaviest on the market. Our expertise in designing and manufacturing agricultural equipment allows us to provide simple and efficient solutions that also offer cost savings. The rollers feature a simplified unfolding system whereby, after hydraulically unlocking the beam that blocks the frame segments, the machine unfolds the side sections when reversing. Subsequently, an actuator lowers all the roller sections. This straightforward mechanical system for folding and unfolding tillage rollers is fast, smooth, and minimizes the use of hydraulic mechanisms.
Spheroidal cast iron
The roller rings manufactured in German foundries are made of high-quality spheroidal cast iron GGG50, noted for its superior resistance to damage compared to the more commonly used gray cast iron in agriculture. Ductile iron features higher strength, plastic properties, and a lower tendency to stress concentration, fatigue strength, and resistance to mechanical damage. Rolmako cultivation rollers utilize components recognized from the most expensive machines on the market.
