Optional extras at additional cost:

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

The discs are made of high-strength boron steel with a hardness of 45–48 HRC, which guarantees a long service life and resistance to abrasion. They deliver effective cutting and intensive mixing of the soil, performing well on various types of ground, even in difficult conditions.

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

High-quality OFAS discs with a diameter of 510 mm are made of hardened steel with a hardness of 48–52 HRC. They guarantee precise cutting of the soil, efficient mixing of crop residues and a long service life even under intensive use in demanding field conditions.

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

OFAS discs with a diameter of 560 mm, made from steel with a hardness of 48-52 HRC, feature very high resistance to wear and damage. The larger diameter allows deeper penetration of the soil and more effective crumbling of plant residues, which increases the output and efficiency of the work.

- Disc bearing

• SKF taper bearings - exceptionally durable and resistant to high loads, they provide smooth and precise action of the discs in all field conditions.
• The AgriHub maintenance-free hub – the fully sealed design protects against dust and moisture, eliminating the need for greasing and minimising servicing requirements.
• The EXTREME hub – reinforced and resistant to impacts as well as overloads, it guarantees maximum reliability when working in demanding terrain.

- Beam with spring finger rake

It is equipped with flexible spring rakes that break up crusting and soil clods, level the surface of the field and spread crop residues evenly, preparing the soil for sowing.

- ALFA disc 560 mm x 5 mm (pcs)

ALFA type discs with a diameter of 560 mm and a thickness of 5 mm guarantee effective cutting and intensive mixing of the soil with plant residue, which speeds up the process of preparing the ground for further agrotechnical operations.

- Delimbe catch crop seeder

A precise seeder for sowing catch crops, allowing even distribution of seed during a single working pass. Simple adjustment and easy operation save time and fuel, increasing the output of field work.

- APV catch crop seeder

The modern APV catch crop seeder ensures accurate seed metering and an adjustable seed rate. It integrates easily with other tillage machines, streamlining the entire soil preparation process.

- Levelling side guard (left-hand side)

It prevents soil from being thrown out to the sides, ensuring an even and neat field surface. It protects the working elements against damage and makes it easier to guide the machine precisely along the edge of the field.

- Front reflective boards

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

- Rear beam with LED lighting

It guarantees excellent visibility of the machine after dark and in unfavourable weather conditions. LED technology provides energy efficiency, resistance to vibration and a long service life of the lighting.

- Maintenance-free roller bearing assemblies (pcs)

The modern, maintenance-free roller bearings have a sealed construction protecting against dust and moisture. As a result they require no greasing, reduce the amount of servicing work and provide dependable operation and a long service life for the whole working assembly.

Detailed description:

• The U622 light disc harrow is a modern, high-performance light disc unit created for fast and effective preparation of the soil, both after the harvest and ahead of sowing.
• The machine, with a working width of 3000 mm and a weight of 1150 kg, works perfectly with tractors from 95 HP upwards, which makes it an ideal choice for medium-sized farms looking for an efficient yet lightweight tillage implement.
• It works excellently 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 a disc harrow for a low-powered tractor, delivering high efficiency with a low power requirement.
• It is fitted with 24 toothed discs with a diameter of Ø510 mm, made from high-strength boron steel with a hardness of 45-48 HRC, which gives them a long service life and resistance to abrasion even when working on heavy, compact 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.
• This solution allows the discs to lift freely when they meet an obstacle, which increases working safety, limits shocks and extends the service life of the whole machine.
• The final levelling of the soil is carried out 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 machine while it works.
• Mechanical working depth adjustment makes it possible to adapt the settings quickly to the soil conditions and to the type of work being carried out, which makes the machine universal and versatile.
• Strong structural steels, laser cutting and powder coating have been used in the construction, which guarantees resistance to corrosion and cracking and ensures a low dead weight.
• The compact build and low weight mean that the machine is easy to transport, very manoeuvrable and does not place an excessive load on the tractor's rear lift.
• The side levelling guards prevent soil from being thrown out to the sides, ensuring even mixing of crop residues across the entire working width.
• The disc harrow makes it possible to mix crop residues into the soil quickly and evenly, improves its structure and increases the organic matter content, which has a positive effect on the fertility of the field.
• High working effectiveness, a low power requirement and ease of operation and maintenance make it an excellent alternative to traditional heavy disc harrows.
• It will perform ideally both as a disc harrow for pre-sowing soil preparation and as a trailed disc harrow for a tractor, significantly shortening cultivation time and lowering running costs.
