- Discs with a diameter of 560 mm (boron steel 45-48 HRC)

The discs, made of wear-resistant boron steel with a hardness of 45–48 HRC, provide a long service life and high strength even under intensive work. They cut through and mix the soil effectively, performing well on various types of ground, including in difficult field conditions.

- OFAS Italy discs with a diameter of 510 mm (hardness 48-52 HRC)

The 510 mm diameter discs from the renowned OFAS brand are made of hard-wearing hardened steel with a hardness of 48-52 HRC. They provide precise undercutting of the soil, effective mixing of crop residues and retain a high level of durability even when working in difficult field conditions.

- OFAS Italy discs with a diameter of 560 mm (hardness 48-52 HRC)

OFAS discs with a diameter of 560 mm offer exceptional resistance to abrasion and damage thanks to hardened steel with a hardness of 48–52 HRC. The greater diameter allows the soil to be loosened more deeply and plant residues to be broken down more efficiently, which increases the work output of the machine.

- Disc bearing

• SKF tapered roller bearings – very durable and resistant to heavy loads, they guarantee smooth and precise operation of the discs even in difficult soil conditions.
• The AgriHub maintenance-free hub – the fully sealed design protects against dust and moisture, eliminating the need for greasing and limiting the need for regular servicing.
• The EXTREME hub – the reinforced design provides resistance to shocks, impacts and overloads, which translates into maximum reliability of operation in demanding terrain.

- Beam with spring finger rake

Fitted with flexible spring rakes that effectively break up crusting and soil clods, level the surface of the field and spread crop residues evenly, preparing the soil for further cultivation operations.

- ALFA disc 560 mm x 5 mm (pcs)

ALFA type discs with a diameter of 560 mm and a thickness of 5 mm provide effective cutting and intensive mixing of the soil with plant residues, which speeds up the preparation of the seedbed for subsequent stages of cultivation.

- Delimbe catch crop seeder

A precise seeder for sowing catch crops, it allows the seed to be spread evenly during a single working pass. Easy to operate and to adjust, it saves time and fuel while increasing the efficiency of field work.

- APV catch crop seeder

The modern APV catch crop seeder makes it possible to meter seed accurately and to adjust the sowing rate. It works perfectly alongside other tillage machines, speeding up and improving the soil preparation process.

- Levelling side guard (left-hand side)

It prevents soil from being thrown out to the sides, so the field surface stays level and neat. It protects the working parts of the machine against damage and helps guide the machine precisely along the field boundaries.

- Front reflective boards

They increase the visibility of the machine during transport on public roads, improving the safety of the operator and of other road users. They meet the current requirements for the marking of agricultural machinery.

- Rear beam with LED lighting

It provides excellent visibility of the machine after dark and in difficult weather conditions. LED technology guarantees low energy consumption, a long service life and resistance to vibration and shocks.

- Maintenance-free roller bearing assemblies (pcs)

The sealed, maintenance-free bearing assemblies of the roller effectively protect the components against dust and moisture, eliminating the need for regular greasing. They ensure a long service life, reliable operation and reduce the time devoted to maintaining the machine.

Detailed description:

• The U622 light disc harrow is a modern and efficient light disc unit, designed for the fast and effective preparation of the soil both after harvest and before sowing, which makes it a universal tool.
• The machine, with a working width of 3500 mm and a weight of 1320 kg, is ideally suited to work with tractors with an output from 110 HP, which makes it an excellent choice for medium-sized holdings looking for an efficient yet light and manoeuvrable disc harrow.
• It works excellently with popular models such as the Ursus C-360, which is why it is often chosen as a disc unit for the C-360 or a disc harrow for a low-power tractor, offering high efficiency with a low power requirement.
• It has been fitted with 28 serrated discs with a diameter of Ø510 mm, made of high-strength boron steel with a hardness of 45–48 HRC, which gives them resistance to abrasion and a long service life, even during intensive work on cohesive and heavy soils.
• Each disc is mounted on an independent arm with a damping spring (13x100 mm) which protects the working components against damage and acts as overload protection.
• Such a mounting system allows the discs to rise freely when obstacles are encountered, which increases safety of work, reduces shocks and extends the service life of the whole machine.
• Final levelling of the soil is handled by a tube roller with a diameter of Ø500 mm, which effectively breaks up soil clods, improves the compaction of the ground and stabilises the work of the harrow during the pass.
• Mechanical adjustment of the working depth makes it possible to match the settings quickly to the current soil conditions and the type of work being carried out, which makes the machine versatile and practical in use.
• The frame structure, made of hard-wearing structural steels using laser cutting and powder coating, guarantees high resistance to corrosion and cracking together with a low own weight.
• The compact design and low weight mean that the machine is easy to transport, highly manoeuvrable and does not place an excessive load on the tractor's rear linkage, which increases the comfort of the operator's work.
• The side levelling guards prevent soil from being thrown out to the sides, guaranteeing even mixing of post-harvest residues across the entire working width and a neat finish to the field surface.
• The disc harrow allows post-harvest residues to be mixed with the soil quickly and evenly, improves its structure and increases the organic matter content, which has a beneficial effect on the fertility and condition of the soil.
• High working effectiveness, a low power requirement and easy operation and maintenance make it an excellent alternative to heavy disc harrows, which call for more powerful tractors and greater fuel consumption.
• The light disc harrow works perfectly as a disc harrow for pre-drilling soil preparation, and also as a trailed disc harrow for a tractor, considerably shortening working time and lowering tillage costs on the farm.
