Field-oriented design

A weed cutter designed for field conditions

Selac was developed to meet the needs of farms looking for a machine capable of working over large widths while maintaining consistent cutting and overall stability.

Its architecture focuses on available power, cutting quality and the ability to operate in a wide range of conditions. The objective is to enable efficient weed topping while ensuring a high level of comfort and control during operation.

Selac includes several adjustment systems to adapt to working conditions and crop configurations.

The cutting height adjustment from 15 cm to 1.80 meters allows intervention at different crop stages. The machine can also be equipped with a 4-function side-slope compensation mast as well as a rear hydraulic power unit, ensuring consistent working quality on uneven terrain.

Product advantages

Key strengths of the Selac

A weed cutter designed to combine power, stability, cutting precision and high field capacity.

High power

High power per meter to maintain cutting efficiency across large working widths.

Consistent operation

Machine stability designed to maintain uniform cutting across the entire working width.

High capacity

A machine designed for farms seeking high field capacity.

Technical design

A robust and high-performance design

The Selac is built on an architecture designed to ensure both available power, mechanical stability and long-term reliability.

Each 1.10-meter section has its own hydraulic motor, ensuring consistent operation across the entire working width.

The slow rotation of the knives, limited to 600 rpm, helps reduce wind effect within the crop and allows more precise intervention on the weed stems to be topped.

Target farms

Which farms is it for?

Thanks to its large working widths, the Selac is primarily designed for farms looking for a high-capacity agricultural weed cutter capable of working efficiently across large areas.

It is suitable for farmers aiming to combine field capacity, cutting quality and technical control within a sustainable weed management strategy.
