Optional extras at additional cost:

- Maintenance-free EXTREME hub

A strong hub created for work in the most demanding field conditions. High-class bearings and tight seals mean it needs no periodic greasing. It guarantees long durability, resistance to loads and dependable work under intensive use.

- Disc ALFA 560 mm x 5 mm

A sturdy disc made of boron steel, 560 mm in diameter and 5 mm thick. It provides precise cutting of crop residues and even mixing of the soil. Thanks to its design it is highly resistant to wear and to mechanical damage.

- SpeedCutter disc 440 mm

A light working disc intended for shallow stubble cultivation. The 440 mm diameter allows effective undercutting and intensive chopping of crop residues. It performs perfectly at high working speeds, increasing the output of the machine.

- SpeedCutter disc 510 mm

A larger model of the SpeedCutter disc with a diameter of 510 mm. It allows deeper, more dynamic mixing of the soil, particularly on heavier sites and with a large amount of organic matter.

- Reinforced Crossboard front drag

A component intended for the initial levelling of the field surface. The reinforced construction increases durability and resistance to loads, effectively breaking up larger soil clods and preparing the soil for further processing.

- Reinforced Crossboard front drag with a stabilising bar

An advanced version of the drag, enhanced with a stabilising bar. It provides even pressure across the whole working width, thanks to which the soil is levelled more thoroughly and prepared for sowing.

- Hydraulic brake

A modern braking system operated by means of hydraulic cylinders. It guarantees effective stopping of the machine both at work and in transport, providing safety and compliance with road traffic requirements.

- Levelling side guards

Side elements that limit the throwing of soil beyond the working line of the machine. They make it easier to keep the field surface even and prevent furrows from forming between passes.

- Front bar with LED lighting

Durable LED lighting with low power consumption, mounted at the front of the machine. It is resistant to shocks and provides good visibility during work and transport.

- Rear beam with LED lighting

Modern rear LED lighting raising safety in road traffic. Fitted with reflectors and type-approved light sources, it provides excellent visibility even after dark.

- Number plate holder with lighting

A durable frame for mounting the registration plate. The integrated LED lighting guarantees that the plate is legible in any conditions and meets legal requirements.

- Cage tube roller Ø 600 mm

A roller of tube construction 600 mm in diameter. It crumbles clods excellently and levels the soil surface, providing stable work even in more difficult field conditions.

- Cage roller with toothed bars Ø 460 mm

A roller fitted with toothed bars with a diameter of 460 mm. It intensively crushes soil and plant residue, being a universal solution for various types of ground.

- Packer toothed roller Ø 460 mm

A working roller with toothed rings 460 mm in diameter. It serves for consolidating and levelling the soil, performing excellently on light and medium soils.

- Packer toothed roller Ø 550 mm

A larger model of the Packer roller with a diameter of 550 mm. Thanks to its greater diameter and mass, it provides more intensive compaction of the ground, particularly in wider machines working in more difficult conditions.

- Ø 450 mm tube-and-ring roller

A roller combining the features of a ring and a tube design with a diameter of 450 mm. It guarantees even consolidation as well as additional crumbling of the soil.

- Crosskill roller Ø 400 mm

A lighter ring roller with a diameter of 400 mm with toothed elements. It works well when crushing and compacting soil on medium and heavy sites.

- Crosskill roller Ø 500 mm

A larger version of the Crosskill roller with a diameter of 500 mm. Built for intensive work, it effectively levels and compacts the soil over large areas.

- Ring roller Ø 500 mm

A steel ring roller with a diameter of 500 mm. It ensures even compaction of the ground and is characterised by a long, failure-free service life.

- Ring roller Ø 600 mm

A larger ring roller with a diameter of 600 mm. Intended for wide machines, it guarantees intensive soil compaction even at a high working speed.

- Spring roller Ø 470 mm

A roller with spring working elements with a diameter of 470 mm. Thanks to its flexibility it adapts well to uneven ground, performing well on light and medium soils.

- Spring roller Ø 550 mm

A larger spring roller with a diameter of 550 mm. It is characterised by greater stability and accuracy of work, which makes it possible to prepare the soil for sowing better, also in demanding conditions.

Detailed description:

• The trailed disc harrow with a working width of as much as 12 metres is a modern premium-class machine, created for work on large farms where maximum output, reliability and time savings count.
• For correct operation the disc harrow requires a tractor with an output of about 420 HP, which makes it possible to fully use the potential of high-power tractors and to guarantee the highest cultivation efficiency.
• The design has been fitted with 96 toothed OFAS discs of Ø 560 mm, which precisely cut through crop residues, mix the soil intensively and leave a perfectly prepared seedbed after only a single pass.
• A disc row spacing of 900 mm ensures a free flow of plant residues, eliminating the risk of clogging, while a working speed of 10–15 km/h guarantees impressive output in a short time.
• The Ø 500 mm tube roller is responsible for even crushing of clods and proper soil compaction, which translates into a better structure of the ground and promotes plant germination.
• The machine makes use of maintenance-free solutions – the AgriHub hubs and the roller bearings do not require greasing, which significantly lowers running costs and helps to avoid unplanned downtime.
• LongLife 40 × 180 mm rubber dampers effectively absorb vibration and protect the structure against overloading, ensuring a long service life even under intensive use.
• Hydraulic working depth adjustment, a transport lock and a support foot make operating the disc harrow convenient and quick, and the settings can be matched to any field conditions.
• In transport the machine guarantees complete safety – a pneumatic braking system, a transport axle on 600/55R22 wheels and additional support wheels 340/55R16 provide stability both on the road and in the field.
• Coupling to the tractor takes place through a Scharmüller drawbar eye with a self-aligning bearing, which ensures smooth interaction, precise guidance and easy manoeuvring.
• The 12 m disc harrow is a solution for farmers looking for machines with the highest output and reliability. It is an investment that increases the productivity of the holding and allows field work to be optimised.
• The solid construction, maintenance-free components and advanced hydraulic systems make this disc harrow equipment ready to work in the most demanding conditions.
• With a working width of 12 m, the disc harrow makes it possible to prepare the field for sowing quickly and evenly, while at the same time ensuring a high level of operator comfort.
• Disc harrows in this series stand out for their versatility, durability and excellent suitability for large areas, which is why they are the ideal choice for holdings that value modern cultivation technologies.
• A 12-metre trailed disc harrow – a guarantee of output, durability and efficiency in intensive cultivation.
