The SUPERSTAR heavy offset disc harrow is designed for a wide range of soil cultivation operations, including primary and secondary tillage in conditions with large amounts of crop residues. Its robust construction and heavy-duty chassis make it suitable for demanding working conditions and deeper soil cultivation.
The series offers different models, allowing farmers to choose the appropriate solution according to the required working width, soil conditions and tractor power.
Main Advantages
Powerful and Compact Design
A simple design ensures ease of operation, while the reinforced chassis is suitable for demanding working conditions.
High Productivity
The precisely designed disc profile and concave shape ensure efficient soil cultivation at an operating speed of 8–12 km/h.
Single Central Chassis
The heavy-duty central chassis allows the discs to penetrate the soil more easily and facilitates deep cultivation. The design also allows a greater disc angle.
Easy Disc Angle Adjustment
The disc angle can be adjusted using the multi-position mechanism on the chassis. This adjustment affects working depth, disc inclination and soil fragmentation. Adjustment can be performed mechanically or hydraulically.
Robust Bearing Housings
Durable roller bearings that require no maintenance or lubrication.
Strong Arm Structure
The welded disc arms are resistant to demanding working conditions and strong impacts.
Easy Chassis Parallelism Adjustment
The spring mechanism connecting the axle to the drawbar keeps the front and rear disc gangs parallel. Adjustment is performed hydraulically. The spring suspension adapts to uneven field surfaces and road conditions, reducing the risk of damage to the frame and discs.
Adjustable Disc Scrapers
Each disc is equipped with a special scraper to remove adhering soil and plant residues. The distance between the scraper and the disc can be adjusted according to working conditions and wear.
Large Disc Clearance
The chassis height is 65 cm, the distance between the discs is 17.5 cm, and the clearance between the front and rear disc gangs is increased. This facilitates soil and crop residue flow and reduces residue accumulation during operation.
Suitable for Deep Cultivation
The heavy-duty construction and adjustable disc angle of up to 25° help achieve greater working depth.
Different Disc Options
Notched and smooth discs are available in different diameters, depending on the model and customer requirements.
