U786 Stubble Cultivator

The U786 features a short disc harrow for shallow and ultra shallow stubble cultivation. It proves effective for the task of removing the nests of the European corn borer in the cornfields. It allows a working width from 3 to 4 m.


The 620 mm diameter and 6 mm thick disc made of boron steel ensures full and accurate undercutting of the soil and intensive mixing of plant residues with straw.

Safety and precision

The stubble cultivator unit is a modern device fitted with an independent system of disc suspension. This solution allows for precisely copying the relief of the field and protects the machine against overloading.


Each of the toothed discs is protected by rubber shock absorbers, which allows them to copy the relief of the field. In addition, they ensure safe operation and safeguard from overloads.

Adjustable cultivator teeth

Mounted behind the discs are scrapers, whose height and angle of inclination can be adjusted. This arrangement allows for an even distribution of crop residues. The scrapers also help to control the flow of the soil stream.


The maintenance-free hubs guarantee a longer service life and reduces failures dramatically.

Work efficiency

Two U786 units can be combined to double the working width and increase productivity.



Rear rollers

It takes a carefully chosen rear roller to make sure that soil is cultivated properly. The rollers are selected based on the type of soil and the end result we seek to achieve.
