The choice of the rotor
Rotostone rotor:
The Rotostone rotor is the ideal solution for working stony soils, thanks to its spade-shaped hoes and reverse rotation with respect to the tractor’s forward movement. This system lifts and separates stones, hard clods, and plant residues, projecting them onto a selection grill that deposits them deeper into the soil, while the finely tilled soil remains on the surface, ready for sowing. The hoes can handle even large stones, ensuring a clean, well-drained seedbed ideal for high-quality crops. Robust and versatile, the Rotostone guarantees excellent performance even on challenging soils, making it a reliable ally for every agronomic need.
Frangiter rotor:
The Frangiter rotor represents a technological advancement in soil tillage, specifically designed for clayey, compact, and hard-to-manage soils. Its aggressive yet controlled action is ensured by sharp, angled hoe blades with a blade-like geometry, which break clods into fine, uniform particles, creating even and high-performing seedbeds. Thanks to its exclusive design, Frangiter optimizes power transmission to the ground, reducing the load on the tractor. The result is outstanding operational efficiency, with low energy consumption and reduced machine wear. The angled flanges, engineered for optimal soil flow, prevent material buildup even in high-moisture conditions, maintaining consistent working depth and soil refinement quality—even in the most challenging soils.
Material S420
The S420 symbol identifies the use of high-strength special steel for the main structural components of the machine. This material ensures high robustness and superior resistance to deformation, even in highly stressed areas such as weld seams, guaranteeing greater durability and long-term reliability.
Vibrating selection grill
Machines marked with this label are equipped with an independent vibrating selection grill, designed to separate stones by channeling them downward while allowing only fine soil to pass through. The dual-spring curl system ensures continuous vibration, preventing build-up and clogging, and delivering smooth, high-quality soil processing even in challenging conditions. On certain models, the working angle is adjustable to optimize performance and reduce power absorption.
Double flange
All machines bearing this label are equipped with a double flange, which enhances the strength of the connection between the blades and the rotor, improving resistance during the most demanding operations. This system reduces the risk of bolt breakage, ensuring greater robustness and operational continuity. Especially suitable for tough soils with significant obstacles, this solution increases machine reliability, reduces unexpected downtime, and extends component lifespan.
Double frame
Machines bearing this label are equipped with a reinforced double frame above the rotor, designed to increase structural rigidity, reduce flexing and deformation, and ensure long-term reliability and durability even under extreme working conditions. The optimised design ensures smooth soil flow without build-up, improving operational efficiency across all soil types. In stony ground, the double-wall structure of the hood protects the machine’s exterior and preserves its integrity, providing an additional advantage in terms of strength and longevity.
Spherical roller bearings
Machines marked with this label are equipped with spherical roller bearings, mounted on hubs and rotor supports. Designed to withstand high radial and axial loads, they provide greater reliability and durability even under heavy-duty conditions. Compared to tapered bearings, they offer 30% higher resistance and, thanks to their self-aligning capability, ensure operational stability and simplified installation without the need for preloading. A technical solution that improves work continuity and reduces machine downtime.
Normalised rotor tube E355
All machines bearing this label are equipped with a normalized rotor tube, a heat treatment process that enhances the material’s mechanical properties, making it more resistant and less prone to breakage.
During normalization, the rotor tube is brought to a specific temperature and then cooled in a controlled manner. This process eliminates internal stresses and creates a more uniform metal structure, reducing the risk of deformation and failure during operation.
Side gear transmission with 3 gears
Machines with this label feature a side gear transmission with three gears, designed to provide maximum strength, reliability, and direct power transfer. Compared to chain systems, it eliminates efficiency losses and reduces maintenance requirements. Ideal for heavy-duty operations, it ensures consistently high performance over time.
Rotor hub
Machines marked with this decal are equipped with a transmission hub featuring an interchangeable shaft, designed to offer maximum reliability against impacts and mechanical stress. Its modular construction ensures operational strength and ease of maintenance: in case of damage, the shaft can be replaced quickly, reducing downtime and ensuring uninterrupted operation.
Floating seals
Machines marked with this label are equipped with floating seals on the rotor end hubs, an advanced sealing system designed to prevent the ingress of dust, mud, and water, even under extreme working conditions. Composed of two opposing metal rings separated by an oil film, the floating seals ensure perfect sealing, reduce wear, and effectively protect bearings and internal lubrication. The result is extended component lifespan, reduced maintenance needs, and maximum operational reliability—even in the presence of vibrations and contaminants.
The choice of the roller
EXPANDED METAL ROLLER
The expanded metal roller is designed for seedbed preparation on light and dry soils, particularly suitable for lawns, gardens, and horticultural crops. Its lattice structure levels the soil without excessive compaction, leaving a slightly uneven surface that helps retain seeds in the event of rainfall. After passing, the soil remains soft on the surface and firm in depth, an ideal condition for uniform germination and better moisture conservation. Working depth is adjustable, either manually or hydraulically, to adapt precisely to every agronomic context.
SMOOTH ROLLER
The smooth roller ensures even compaction and precise levelling, making it ideal for vegetable sowing and plastic mulch laying. It improves transplanting efficiency, reduces evaporation, and creates a uniform surface ready for use. Working depth is adjustable, either manually or hydraulically, to adapt precisely to every agronomic context.
PACKER ROLLER
The packer roller ensures optimal seedbed preparation by combining uniform compaction, soil refinement, and operational stability. Ideal for light to medium soils, it enhances soil structure and water retention. Its wide contact surface provides stable support for the machine, while the triangular teeth effectively break surface crusts, facilitating drainage. The roller cleaner with individually adjustable steel scrapers prevents clogging, even in moist conditions. Working depth is adjustable, either manually or hydraulically, to adapt precisely to every agronomic context.
UNIVERSAL ROLLER
Designed with long welded ridges on its surface, this roller stands out for its effectiveness on all soil types, ensuring high performance in every season. Its universal configuration makes it the ideal solution to eliminate the need for seasonal rollers, providing a reliable and ready response even on sandy soils, where traditional rollers tend to jam. The enlarged ridges promote consistent rotation and improve the overall quality of soil preparation. Working depth is adjustable, either manually or hydraulically, to adapt precisely to every agronomic context.
