Optional extras at additional cost:

- Maintenance-free EXTREME hub

A hub designed for long-lasting, problem-free use. High-class bearings and a sealed protection system mean it requires no periodic greasing. It guarantees reliability in the field, resistance to overloading and fault-free work even under heavy load.

- Disc ALFA 560 mm x 5 mm

A strong working disc made from boron steel with a diameter of 560 mm and a thickness of 5 mm. Thanks to its appropriate dimensions it provides thorough undercutting of post-harvest residues and even mixing of the soil. The durable construction effectively counteracts cracking and excessive wear.

- SpeedCutter disc 440 mm

A compact disc intended for fast, shallow soil cultivation. The 440 mm diameter allows intensive cutting and chopping of crop residue. Ideal for working at high speed, which raises the output of the whole unit.

- SpeedCutter disc 510 mm

A larger version of the SpeedCutter disc, with a diameter of 510 mm. It provides deeper and more vigorous mixing of the soil, performing especially well on heavy sites and where there is a large amount of crop residue.

- Reinforced Crossboard front drag

A hard-wearing component used for the initial levelling of the field surface. The reinforced structure increases resistance to damage and extends the service life. It effectively breaks up soil clods and prepares the field for further cultivation.

- Reinforced Crossboard front drag with a stabilising bar

An extended version of the front drag, supplemented with an additional stabilising bar. It provides even pressure across the full working width and better preparation of the soil for further treatment.

- Hydraulic brake

A braking system based on hydraulic cylinders, guaranteeing that the machine is stopped effectively. It raises safety during transport and work in the field and meets the legal requirements for road traffic.

- Levelling side guards

Components that limit soil spilling beyond the outline of the machine. They make it easier to keep an even surface after the pass and eliminate the formation of furrows.

- Front bar with LED lighting

A modern front lighting system using LED technology. It is characterised by low energy consumption, resistance to shocks and a long service life. It provides good visibility of the machine during work and transport.

- Rear beam with LED lighting

LED rear lighting that increases the safety of the machine in road traffic. Fitted with reflectors and type-approved light sources, it provides good visibility also at night.

- Number plate holder with lighting

A sturdy frame allowing a registration plate to be mounted. The built-in LED lighting guarantees that the marking remains legible in all conditions, in line with regulations.

- Cage tube roller Ø 600 mm

A steel roller 600 mm in diameter, based on a tube construction. It effectively breaks up soil clods and levels the field surface, remaining stable even in difficult conditions.

- Cage roller with toothed bars Ø 460 mm

A cage roller with special toothed bars. Its diameter of 460 mm ensures effective breaking down and crumbling of the soil, making it a universal solution for various types of ground.

- Packer toothed roller Ø 460 mm

A roller fitted with toothed rings 460 mm in diameter. It allows effective consolidation of the soil and its preparation for sowing. Excellent for light and medium soils.

- Packer toothed roller Ø 550 mm

A larger variant of the Packer roller – 550 mm in diameter. It allows stronger pressing and even soil compaction. It proves itself in wide units and in more demanding conditions.

- Ø 450 mm tube-and-ring roller

A construction combining the features of a tube roller and a ring roller. The 450 mm diameter provides even consolidation of the soil, while the additional rings crumble it effectively.

- Crosskill roller Ø 400 mm

A lighter ring roller with a diameter of 400 mm. Thanks to its toothed elements it crushes the soil well and compacts it, performing well on medium and heavy sites.

- Crosskill roller Ø 500 mm

A larger version of the Crosskill roller – 500 mm in diameter. Adapted to more intensive work and to levelling the soil over large areas.

- Ring roller Ø 500 mm

A steel roller with a diameter of 500 mm built from rings. Its task is to compact the ground evenly. The durable design ensures reliability for many seasons.

- Ring roller Ø 600 mm

A larger variant of the ring roller - 600 mm in diameter. Used in machines with a large working width, it provides intensive consolidation and levelling of the soil even at high speed.

- Spring roller Ø 470 mm

A roller with spring elements that follow unevenness in the terrain well. The diameter of 470 mm makes this a light, versatile construction intended for light and medium soils.

- Spring roller Ø 550 mm

A larger version of the spring roller, with a diameter of 550 mm. It ensures more stable and more accurate work, preparing the soil perfectly for sowing even in more difficult conditions.

Detailed description:

• The trailed disc harrow with a working width of 9 metres is a modern and efficient tillage unit that ideally answers the needs of large farms focused on maximum effectiveness and time savings.
• The machine requires a power input of 300 HP, which means it works excellently with high-power tractors, allowing their potential to be fully used and providing high output even on the largest areas.
• The frame has been equipped with as many as 72 serrated OFAS discs of Ø 560 mm, which precisely cut through crop residue, mix the soil intensively and guarantee even preparation of the field for sowing in a single pass.
• A disc row spacing of 900 mm allows plant residues to flow through freely, eliminating the risk of the machine clogging, while a working speed of 10–15 km/h makes it possible to achieve impressive output.
• The Ø 500 mm tube roller ensures even crushing of clods and optimum soil compaction, which translates into better soil structure and ideal conditions for the germination of plants.
• The disc unit uses modern maintenance-free solutions - the AgriHub hubs and roller bearings require no greasing, which significantly lowers running costs and minimises downtime.
• LongLife rubber dampers measuring 40 × 180 mm protect the machine against overloads and reduce vibration, increasing the service life of the whole structure even during long and intensive work.
• Hydraulic systems make the machine easier to operate – working depth adjustment, the transport lock and the support foot. Thanks to them the operator can quickly adapt the settings to the soil conditions and manoeuvre the machine comfortably.
• In transport the disc harrow is completely safe – the pneumatic braking system and the transport axle with 600/55R22 wheels ensure sure handling, while the additional 340/55R16 support wheels improve stability both in the field and on the road.
• The machine is coupled to the tractor by means of a solid Scharmüller drawbar eye with a self-aligning bearing, which guarantees smooth interaction, precise guidance and great manoeuvrability even on uneven surfaces.
• The 9 m disc harrow is a machine dedicated to farmers who expect the highest quality and output. Its solid construction, maintenance-free components and advanced hydraulic solutions make it a dependable partner in intensive tillage.
• This is a disc harrow created for special tasks - it allows fast, even and effective preparation of the soil regardless of field conditions, while guaranteeing comfort for the operator.
• Investing in such a modern disc harrow is a guarantee of increased farm output, optimised operating costs and full use of the potential of modern agricultural tractors.
• The disc harrows in this series stand out for their durability, versatility and excellent match to the needs of large farms that require reliable machines ready to work in any conditions.
