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.
The three families of Massano Bed former shapers
SHORT BED FORMER SHAPER
Low and wide beds for shallow-rooted vegetables
Ideal for crops with shallow root development, the short-profile bed former shaper is designed to create low and wide beds, ensuring a broad, stable, and well-aerated seedbed.
Its compact structure and wider shaping angle promote fast and uniform soil distribution, minimizing draft resistance and optimizing sowing operations over large surface areas.
LONG BED FORMER SHAPER
High and narrow beds for vertically developing vegetables
The long-profile bed former shaper is designed to create high and narrow beds, ideal for ensuring a deep, compact, and well-structured seedbed.
Its elongated geometry allows for a gradual upward channelling of soil, enabling precise and uniform shaping even in light or sandy soils. This design promotes deeper root penetration, which is essential for vegetables whose edible parts develop underground.
PARALLELOGRAM FRAME BED FORMER SHAPER
Deep beds and independent control for maximum agronomic flexibility
Designed to provide a higher level of operational precision and adaptability, the parallelogram-frame bed former shaper follows the same principle as the long-profile version but introduces a key innovation: independent adjustment of the shaper in relation to the machine frame.
This configuration allows bed shaping without loading the machine frame, making the stone burier fully independent. As a result, it enables deeper working depths without interference, optimizes terrain adaptation, and reduces tractor effort.

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.
High ground clearance under frame
Machines bearing this label are designed with a wide clearance under the frame, allowing large stones to pass through easily, preventing blockages and ensuring a constant soil flow. Ideal for stony or wet soils, this configuration reduces material build-up between the rotor and the structure, enhancing operational continuity, productivity, and working quality even in the most demanding conditions.
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.
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.
ASA HE chain side transmission
The ASA HE chain transmission uses reinforced roller chains with heat-treated induction-hardened pins to ensure greater fatigue resistance and tensile strength. Ideal for heavy-duty applications and intensive work cycles such as on heavy machinery and conveyors, this solution offers superior reliability, toughness, and durability compared to standard chains
Welded steel housing
Machines with this label are equipped with a high-strength welded steel housinghigh-strength welded steel housing, serving both as protection and structural support for the chain transmission. The welded construction eliminates weak points, increasing lateral rigidity and durability lateral rigidity and durability even under heavy-duty working conditions. The cover, fitted with a Flexoil seal, ensures proper lubricant containment and protects it from dust and external agents, guaranteeing long-term efficiency and reliability.
