Optional extras at additional cost:

- Maintenance-free EXTREME hub

A hub built with maximum durability and minimum servicing requirements in mind. Thanks to the use of high-quality bearings and seals, the EXTREME hub requires no greasing throughout its entire working life. It guarantees a long service life, resistance to overloads and reliable operation even in difficult soil conditions.

- Disc ALFA 560 mm x 5 mm

A solid tillage disc made of boron steel. A diameter of 560 mm and a thickness of 5 mm ensure optimum undercutting of crop residues and mixing of the soil at the right depth. Thanks to its reinforced construction, it is highly resistant to wear and cracking.

- SpeedCutter disc 440 mm

A light, fast-working disc intended for shallow stubble cultivation. The 440 mm diameter allows intensive cutting and even chopping of crop residues. It is excellent for work at high working speeds, which increases the output of the unit.

- SpeedCutter disc 510 mm

A larger variant of the SpeedCutter disc, offering even deeper undercutting and intensive mixing of the soil. The diameter of 510 mm means this component copes excellently in conditions with a large amount of post-harvest residue and on heavier soils.

- Reinforced Crossboard front drag

A working element intended for levelling the soil surface ahead of the discs. The reinforced construction increases resistance to mechanical damage and extends the service life. It effectively breaks up soil clods and levels the field, which makes further cultivation easier.

- Reinforced Crossboard front drag with a stabilising bar

An improved version of the front drag, fitted with an additional stabilising bar. This solution ensures even pressure across the entire working width, improving the quality of cultivation and soil levelling. Ideal for work in varied field conditions.

- Hydraulic brake

A dependable braking system based on hydraulic rams. It provides high braking effectiveness during transport and when manoeuvring the machine. It guarantees operator safety and compliance with road traffic regulations.

- Levelling side guards

Special side elements that limit soil being thrown outside the outline of the machine. They keep the soil structure even after the pass and prevent furrows forming where passes meet. They increase both the neatness and the functionality of the cultivation.

- Front bar with LED lighting

Complete front lighting in LED technology, providing maximum visibility of the machine at night and during road transport. It features low energy consumption, great durability and resistance to vibration.

- Rear beam with LED lighting

Modern rear lighting based on LED technology. It provides excellent visibility of the machine from long distances and increases safety in road traffic. Fitted with reflective elements and type-approved light sources.

- Number plate holder with lighting

A practical frame for mounting the registration plate. It is fitted with energy-saving LED lighting, which allows the machine to be marked correctly and legibly during transport in line with legal requirements.

- Cage tube roller Ø 600 mm

A large-diameter roller made of hard-wearing steel tubes. It provides intensive breaking up of soil clods and levelling of the field surface. The diameter of 600 mm guarantees stable operation even in heavy soil conditions.

- Cage roller with toothed bars Ø 460 mm

A compact cage roller with special toothed strips. Thanks to its construction it crumbles the soil and breaks down plant residues very well. The diameter of 460 mm makes it universal and suitable for various soil types.

- Packer toothed roller Ø 460 mm

A roller intended for consolidating and levelling the soil. Toothed rings with a diameter of 460 mm provide good breaking up of clods and leave the soil in ideal condition for sowing. It performs well when working on light and medium soils.

- Packer toothed roller Ø 550 mm

The larger diameter – 550 mm – allows even better pressing and firming of the soil. This roller is particularly recommended for wide tillage units working in more difficult field conditions.

- Ø 450 mm tube-and-ring roller

It combines the features of a tube roller and a ring roller. The 450 mm diameter structure ensures even soil compaction, while the rings additionally improve crumbling. A versatile and universal solution.

- Crosskill roller Ø 400 mm

A ring roller with toothed elements, intended for intensive crumbling and consolidation of the soil. The diameter of 400 mm guarantees light, stable work. Excellent for medium and heavier soils.

- Crosskill roller Ø 500 mm

An enlarged version of the Crosskill roller - diameter 500 mm. It allows more effective levelling and consolidation of the soil over a large area. It performs exceptionally well when preparing the field for sowing.

- Ring roller Ø 500 mm

A solid ring roller with a diameter of 500 mm. Its task is to compact the soil evenly across the entire width of the machine. The durable construction ensures many years of use.

- Ring roller Ø 600 mm

A larger version of the ring roller with a diameter of 600 mm. Used in wide machines, it allows more intensive compaction and levelling of the soil. It performs excellently when working at high speed.

- Spring roller Ø 470 mm

A roller fitted with spring working elements, which adapt perfectly to unevenness in the soil. Its diameter of 470 mm makes this roller light and highly versatile. It is particularly recommended for light and medium soils.

- Spring roller Ø 550 mm

A larger version of the spring roller – Ø 550 mm. It is characterised by greater stability and more intensive operation, which allows more thorough levelling of the soil and preparation of the field for sowing in more difficult conditions.

Detailed description:

• A trailed disc harrow for large tractors is an efficient tillage machine intended for farms that put their money on working speed and efficiency.
• With a working width of 8 metres and a power requirement of 260 HP, the disc harrow performs excellently in combination with high-power tractors, guaranteeing high output on large acreages.
• The machine is fitted with 64 serrated OFAS discs with a diameter of 560 mm, which precisely cut post-harvest residues and mix the soil effectively, creating ideal conditions for sowing.
• The appropriate spacing of the disc rows (900 mm) ensures a smooth flow of plant residue, and the working speed of 10–15 km/h makes it possible to achieve excellent results in a short time.
• Even crumbling and consolidation of the soil is handled by the Ø 500 mm tube roller, which performs excellently on various soil types.
• A great advantage of this disc harrow are its maintenance-free solutions – the AgriHub hubs and the roller bearings require no servicing, which lowers maintenance costs and eliminates downtime.
• The LongLife 40 × 180 mm rubber dampers that have been used effectively absorb vibrations and protect the structure during intensive work.
• Comfort of use is increased by hydraulic depth adjustment, and also by the hydraulically controlled transport lock and support foot.
• Safety during transport is guaranteed by a pneumatic brake and a solid transport axle on 600/55R22 wheels supported by 340/55R16 support wheels.
• Thanks to the Scharmüller drawbar eye with a self-aligning bearing, the disc harrow works securely together with the tractor, providing stability and smooth manoeuvring even on uneven surfaces.
• This high-power disc harrow is the ideal solution for farmers who expect high output, reliability and durability.
• A solid construction, maintenance-free components and modern hydraulic solutions mean that the disc harrow performs excellently in intensive tillage, preparing the soil in a fast, even and efficient manner.
• This is an investment that allows the potential of modern tractors to be used in full and the profitability of field work to be increased.
