The Rolmako field leveling roller is a fully hydraulic design suitable for modern farms demanding high-quality, efficient, and durable equipment. The Rolmako field leveling roller meets stringent requirements for compactness; despite its large working widths, it can be folded to a transport width of less than 3.0 m, facilitating convenient, easy, and safe travel on public roads. The hydraulic system allows the entire process of unfolding to the working position and folding to the transport position to be performed from the tractor cabin without the need for additional maneuvering or stepping out. The Cambridge roller is ideal for pre- and post-sowing treatments, significantly impacting crop quality. It retains soil moisture effectively, making it particularly useful in dry conditions. It consists of alternately mounted toothed discs and flat rings that rotate independently during travel on the field. These elements are self-cleaning due to the difference in rotational speed, preventing soil clogging. Orion rollers are utilized for cultivating arable land and grasslands. Equipped with Orion rings, the roller is perfect for pre-sowing cultivation. On grasslands, the Orion roller stimulates grass tillering, assists in sowing, and maintains existing resources. It is also effective for stubble cultivation, aiding in the distribution of post-harvest residue, especially when combined with a cutting knife roller.
Cambridge or ORION - a design that offers an advantage
Preparing the seedbed is more efficient and straightforward
Rolmako rollers are engineered for additional pre-sowing soil cultivation, particularly under challenging, dry conditions. These rollers efficiently crush clods and compact the soil due to their substantial mass, enhancing its absorption capacity. Retaining soil moisture promotes vigorous and uniform plant emergence, even during droughts. The Rolmako roller is versatile for use both before and after sowing, with post-sowing applications speeding up plant vegetation. An added benefit is the reduced risk of damage and excessive wear to cultivation machinery due to stones. As it moves, the Rolmako roller presses stones deeper into the soil, thus minimizing the risk of obstructing seeding equipment. Its unique frame design adapts to the terrain, ensuring uniform pressure across the entire working width. The overlapping roller sections ensure consistent operation over the entire width, even on uneven fields and slight headlands. Rolling also offers an effective method for clearing stones from the field. Optionally, the roller can feature stone containers for transporting boulders and adding extra weight. The rollers can be equipped with a dual-circuit brake system for pneumatic or hydraulic systems, according to user preferences.
Many technical solutions tailored to user preferences
Rolmako rollers are available in working widths ranging from 6.2 m to 9.4 m, with a choice of working rings. These include a Cambridge ring with a diameter of 530 mm or a spheroidal cast iron ORION ring with a diameter of 500 mm. Both types are designed for challenging conditions, but for grasslands, sticky and sandy soils, and predominantly post-sowing tasks, the ORION variant is recommended. An additional option is the hydraulically controlled Crossboard drag, ideal for spring soil cultivation, preliminary surface leveling, and furrow crumbling. Made of hardened springs and bent working attachments, the drag breaks up clods and levels the field, creating an optimal pre-sowing surface. It performs well on stony fields as it does not pull stones to the surface. For difficult conditions, an optional stabilizing beam can be mounted, connecting the working elements into one unit for improved leveling effects. When a hard crust forms on the field surface, the aggressive DoubleKnife tine skid is appropriate. Another available option is the front cutting knife roller, designed for intensive shredding of post-harvest residues from corn and rapeseed and green mass of catch crops. Both the Crossboard and the knife roller are controlled from the tractor cabin using a hydraulic circuit.

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.
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.
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.
Knife roller
The knife roller mounted at the front of the machine before the main rollers enables enhanced and intensive shredding. The oblique arrangement of the knives ensures even distribution of the cutting force, resulting in optimal performance. Solid, maintenance-free bearings and knives made of boron steel provide a long service life. The closed core of the roller is highly resistant to stones and clogging with crop residues. Double-sided knives, sharpened on both sides, reduce wear costs by half.
Roller folding and unfolding system
The Cambridge/ORION rollers are folded and unfolded for transport via hydraulic control. Initially, the side arms are lifted by the central hydraulic cylinder to disengage them from the transport sockets, enabling the side piston rods to unfold the arms. Subsequently, the central piston positions the rollers towards the ground. The machine is engineered to allow the rollers to adapt and align freely with the cultivated terrain.
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.
