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

Discs made from strong boron steel with a hardness of 45-48 HRC feature high resistance to abrasion and damage, which gives them a long service life even under intensive use. They cut and mix the soil effectively, performing well in various soil conditions, including on difficult and compact ground.

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

High-quality OFAS discs with a diameter of 510 mm, made of hardened steel with a hardness of 48–52 HRC, guarantee precise cutting of the soil and effective mixing in of harvest residue. Their resistance to abrasion and damage gives them a long service life, even under intensive use.

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

OFAS discs with a diameter of 560 mm, made of hardened steel with a hardness of 48–52 HRC, stand out for their exceptional durability and resistance to wear. The larger diameter makes it possible to loosen the soil more effectively and to shred plant residues more thoroughly, which increases the efficiency of the work.

- Disc bearing

• SKF taper bearings - exceptionally strong and resistant to high loads, they provide smooth, precise action of the discs in all working conditions.
• The AgriHub maintenance-free hub - the sealed construction protects against moisture and contamination, eliminates the need for greasing and minimises the need for frequent servicing.
• EXTREME hub – the reinforced design provides resistance to shocks, impacts and overloads, guaranteeing failure-free operation in the most demanding conditions.

- Beam with spring finger rake

It is fitted with flexible spring rakes that effectively break up soil clods, remove surface crusting and level the field surface, spreading crop residue evenly and preparing the soil for sowing.

- ALFA disc 560 mm x 5 mm (pcs)

ALFA discs with a diameter of 560 mm and a thickness of 5 mm guarantee intensive mixing of the soil with plant residues and effective cutting, which speeds up preparation of the field for subsequent tillage operations.

- Delimbe catch crop seeder

A precise seeder for sowing catch crops, allowing even, accurate distribution of seed during a single pass. Easy to adjust and operate, it increases work efficiency while saving time and fuel.

- APV catch crop seeder

The modern APV catch crop seeder ensures accurate seed metering and the option to adjust the seed rate. It works excellently with other tillage machines, speeding up the entire soil preparation process.

- Levelling side guard (left-hand side)

It prevents soil from being thrown to the sides, keeping the field surface even and neat. It protects the machine's working parts against damage and makes precise steering along the plot boundaries easier.

- Front reflective boards

They improve the visibility of the machine during transport on public roads, increasing the safety of the operator and other road users. They meet the standards in force 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. The LED lighting features low energy consumption, a long service life and resistance to vibration and shocks.

- Maintenance-free roller bearing assemblies (pcs)

The modern, maintenance-free bearing units of the roller have a fully sealed design which protects against dirt and moisture. This eliminates the need for greasing, reduces servicing outlay and ensures long-lasting, trouble-free operation of 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 4000 mm and a weight of 1480 kg, works ideally with tractors with an output from 120 HP, which makes it an excellent choice for medium and larger holdings looking for efficient yet light and manoeuvrable equipment.
• It can be used with popular models such as the Ursus C-360, which is why it is often chosen as a disc harrow for the C-360 or as a classic disc harrow for a tractor of moderate power.
• It is fitted with 32 serrated discs with a diameter of Ø510 mm, made of tough boron steel with a hardness of 45–48 HRC, which gives them a long service life and resistance to abrasion even when working in difficult soil conditions.
• Each disc is mounted on an independent arm with a damping spring (13x100 mm), which serves as overload protection and shields the working parts from damage.
• This type of mounting system enables the discs to rise freely when an obstacle is encountered, which improves safety during work, reduces vibration and prolongs the durability of the machine.
• Final soil levelling 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 operation of the machine.
• Mechanical working depth adjustment allows the parameters to be adapted rapidly to the soil conditions and the type of operations being performed, which makes the implement versatile and convenient to use.
• The frame, built from high-strength structural steels using laser cutting and powder coating technology, guarantees resistance to corrosion and cracking together with a low dead 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 sideways, ensuring even mixing of crop residues across the entire working width and a neat finish of 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 positive effect on the fertility and condition of the soil.
• Its high work effectiveness, low power requirement and easy operation and maintenance make it an excellent alternative to heavy disc harrows that demand greater fuel input and more powerful tractors.
• The light disc harrow is ideally suited as a disc harrow for pre-sowing soil preparation and as a trailed disc harrow for a tractor, significantly shortening working time and lowering cultivation costs.
