Optional extras at additional cost:

- EXTREME hub

A reinforced hub designed for work in the most demanding conditions. Resistant to heavy impacts and large loads, it provides a long service life and reliable operation even under intensive use. This is a solution created for farmers who put maximum durability and freedom from breakdowns first.

- Bar with a finger finger rake

A practical component used for levelling the field and crumbling larger soil clods. The finger rake improves the structure of the ground, preparing it for the subsequent stages of cultivation. It leaves an even and neat surface, which raises the quality of the work carried out.

- Beam with spring finger rake

The flexible construction allows precise adaptation to the shape of the terrain. It makes it easier to level the ground evenly and to mix crop residues effectively, which improves the structure of the soil and speeds up its preparation for sowing. An ideal solution in changeable field conditions.

- 3D shock absorber with a 35 x 35 mm spring

An innovative damping system that absorbs vibrations and protects the machine against overloads. It ensures stable and smooth operation of the discs, increases operator comfort and reduces wear on the working parts, extending the service life of the whole machine.

- Disc ALFA 560 mm x 5 mm

A durable disc made of high-quality steel, with a diameter of 560 mm and a thickness of 5 mm. It cuts into the soil effectively and mixes crop residue intensively, guaranteeing even preparation of the field for further agrotechnical work.

- Disc 610 mm x 6 mm with a reinforced leg

Created for work in the most demanding soil conditions. The greater disc diameter and thickness, combined with a reinforced stem, provide exceptional strength and effectiveness when cultivating hard and stony soils.

- Support wheels 400/60-15.5 for the semi-mounted version

Wide wheels increase the stability and balance of the machine and make transport and precise manoeuvring easier. Thanks to them, work proceeds smoothly and safely even on difficult ground, which additionally raises the durability of the structure.

- Levelling side guards

They limit the throwing of soil beyond the working area, which makes it possible to obtain an evenly cultivated field. In addition, they protect the working parts against damage and support effective soil mixing, raising work efficiency.

- Delimbe catch crop seeder

A modern unit allowing fast, accurate sowing of catch crops during a single pass. It makes work easier, reduces fuel consumption and helps improve soil fertility, encouraging its regeneration and sustainable farm management.

- Front bar with LED lighting (semi-mounted machines)

Additional LED lights mounted on the front beam provide better visibility during work and transport in poor lighting conditions. They are characterised by low energy consumption, high durability and resistance to vibration.

- Rear beam with LED lighting

Modern LED rear lighting ensures excellent visibility of the machine after dark and in difficult weather conditions. The durable LED diodes are distinguished by a low failure rate and a long service life, which guarantees safe operation for many years.

- Pneumatic brake

A braking system used in agricultural machines of larger dimensions and weight. It uses compressed air to actuate the braking mechanism, which provides effective, safe stopping of the machine during road transport.

- Hydraulic brake

A system based on the pressure of the working fluid, characterised by fast action and great precision. It allows smooth, safe braking, increasing control over the machine in a variety of conditions.

Detailed description:

• The semi-mounted disc harrow with a working width of 4000 mm is a professional tillage machine created with large farms in mind, farms that expect maximum output, reliability and precision of work.
• This sturdy disc harrow works with tractors from 150 HP upwards, which allows its capabilities to be used effectively while at the same time providing stability and operating comfort even in difficult field conditions.
• The machine, weighing 3900 kg, has been fitted with 32 serrated discs with a diameter of Ø560 mm from the renowned manufacturer OFAS. These discs stand out for their high resistance to abrasion, their durability and their effectiveness even on heavy and demanding soils.
• Thanks to the large gap between the discs and the 900 mm row spacing, the unit offers excellent throughput, which allows free mixing of post-harvest residues without the risk of the structure clogging.
• Each disc has been mounted on an arm with a LongLife 40x180 mm rubber damper, which absorbs vibration, protects structural components against overloading and guarantees smooth operation even in fields with a large number of stones.
• AgriHub maintenance-free hubs are a solution that significantly reduces running costs - they eliminate the need for greasing, shorten servicing time and provide reliability of the working assembly over a long period of use.
• The unit is equipped with a Ø500 mm tube roller, whose task is to break up soil clods, level the field surface and improve the soil structure, which allows the ground to be properly prepared for further agrotechnical operations.
• Hydraulic working depth adjustment of up to 150 mm allows the working parameters to be matched quickly to the soil type and current needs, while the hydraulic folding system makes transporting and storing the machine convenient and trouble-free.
• The disc harrow works at a speed of 10–15 km/h, which translates into fast and uniform preparation of large field areas in a short time.
• This is not only a light disc harrow, but also a hard-wearing tractor disc harrow that can replace heavy trailed disc harrows for tractors, while offering simple operation, low running costs and many years of durability.
• Thanks to its well-thought-out design, the machine does not place an excessive load on the tractor lift, which ensures failure-free operation and extends its service life.
• The 4 m disc harrow in the semi-mounted version is an excellent solution for farmers looking for a reliable disc harrow for the c-360 and other popular tractor models. It is ideally suited to cutting and mixing in harvest residue, stubble cultivation and preparing the soil for sowing.
• This is a versatile, modern machine, which combines high efficiency, durability and easy operation, considerably improving comfort of work and quality of cultivation on any holding.
