Front compacting and finishing rollers

Rolmako is one of the few manufacturers of cultivation tools offering a comprehensive range of front-mounted solutions, allowing tasks to be performed at the front of the tractor. A second machine can be mounted on the same tractor's rear lift. The rollers on the front three-point linkage in the SOLO version can be enhanced with optional tools such as a drag, SU tines, and various levelling drag variants. The working elements are safeguarded against excessive load by springs. The front joint permits the frame to turn. The rollers in the guides and slides are made of polyamide. An increasing number of farmers and service companies are adopting Rolmako tools for the tractor's front three-point linkage. These designs are well-conceived and continually refined to improve soil cultivation without additional costs. To create ideal sowing conditions and reduce the number of field passes required beforehand, it is economically justified to support the operation of the cultivation and seeding units by mounting various types of press rollers on the tractor's front three-point linkage.

Instead of dead ballast, perform the correct task at the front of the tractor

Rolmako offers a range of cultivation rollers designed for use on the tractor's front linkage. Solo rollers can also be mounted on the rear three-point linkage. The universal frame design accommodates any roller system available. Mounting the machine on the front three-point linkage enables simultaneous operations using tools at the front and rear of the tractor. The website features basic tools for the front three-point linkage. Rolmako can custom-make any machine to meet specific customer needs. Instead of heavy rollers, the manufacturer can install lighter pipe or string rollers. Machines for the tractor's front three-point linkage provide an efficient solution by performing additional tasks in a single tractor pass. Heavy rollers enhance the tractor's controllability, acting as front ballast.

The goal is always the same, to maximize the possibilities

Most agricultural tractors sold today are equipped with a front hydraulic lift. To meet farmers' expectations, our company has introduced various proposals for machines mounted on the front of the tractor, thereby increasing cultivation possibilities. All machines on the front three-point linkage of the tractor are equipped with a tower compliant with category II agricultural hitch. An optional attachment, in the form of a cultivator, supports pre-sowing cultivation. The combination of the roller and the harrow creates an ideal tool for cultivation work following ploughing. A special torsion mechanism built into the upper suspension system protects the tractor and the machine from excessive load. In Rolmako machines, all roller axles are machined for bearings with a diameter of 50 mm. Standard service roller bearings can be replaced with optional maintenance-free bearings. Passive tools allow for the effective improvement of work travels in the field. Using the machine on the front of the tractor, instead of front axle weights, enables better crop yields.

Cultivating extension

When cultivation with tines is required, an attachment with cultivator tines can be successfully mounted. In cultivator attachments, adjustment is performed steplessly using a lever. A tine depth scale is mounted on the machine. By equipping any roller with a two-row or three-row cultivator attachment, a fully-fledged cultivation unit is mounted on the front of the agricultural tractor.

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.

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.

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.

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.

The purpose depends on the selection of the roller

Cambridge rollers exert an intensive crushing effect, featuring two types of working elements: smooth, flat rings with cutting discs, alternated with toothed discs. These discs, larger in diameter than the rings, not only crush but also prevent the roller from clogging with moist soil. The Crosskill roller is optimal for pre-cultivation and seeding preparation, effectively leveling and crushing clods of earth. The Twin Disc double disc roller, designed for the tractor's front three-point linkage, is aggressively suited for pre-sowing work after ploughing and post-harvest work on stubble fields, providing additional support for stubble cultivators and disc harrows. The steel ring roller (often referred to as DD) excels in conditions where rollers made of the finest cast iron fail, particularly on stony fields. The Campbell roller, designed for deep action, features narrow rings with diameters of 560 mm or 700 mm spaced widely apart, effectively acting as a furrow packer in loosened soil layers to accelerate settlement post-ploughing. Self-cleaning star-shaped rings with alternating diameters compact the soil in two layers, while the aggressive teeth of the Orion roller ensure superior soil cultivation—compact below and loosened on top. Cast iron GGG50 castings enhance durability and efficiency, resulting in a better seed layer with fewer working passes.

Universal support frame

Machines for the front three-point linkage of the tractor consist of a universal supporting frame to which the rollers and other cultivation tools selected by the Customer are attached.

Cultivator attachment

When cultivation with tines is required, an attachment with cultivator tines can be successfully mounted. In cultivator attachments, adjustment is performed steplessly using a lever. A tine depth scale is mounted on the machine. By equipping any roller with a two-row or three-row cultivator attachment, a fully-fledged cultivation unit is mounted on the front of the agricultural tractor.

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.

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.

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.

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.
The front-pushed unit does not impede steering. It is loosely connected to the main frame, allowing for lateral movement. This design ensures that a slight turn of the tractor wheels does not create significant stress on the unit. Initially, it moves sideways relative to the tractor's axis, but springs return it to the central, optimal position. The active front weight is beneficial beyond sowing, aiding in crushing and reconsolidation for an ideal seedbed. These features prevent the tractor from sinking, conserving fuel and assisting in leveling before the seeder.
The direct benefits of using rollers include leveling the field and breaking up clods, enhancing seed-soil contact which significantly impacts the uniformity of emergence, retaining moisture, reducing soil erosion, and improving soil structure.
The machine is mounted on the front three-point linkage, which is lowered to the maximum extent during operation, allowing the entire weight to rest on the cultivation rollers. It is designed for compacting the top layer of soil immediately after ploughing, prior to sowing, and creating its lumpy structure. These machines are particularly useful on cohesive, clayey soils, where they break up ploughed ridges and clods while simultaneously compacting and leveling the top layer of soil.
