What is an agricultural weed cutter?
A weed cutter is a mechanical weeding tool designed to cut weeds growing above the crop canopy. By removing the upper part of weeds before seed production, it helps limit their spread and sustainably reduce weed pressure in the fields.
Limit seed production
Weed cutting removes dominant weeds before they produce seeds, helping slow their spread in the crops.
Reduce weed pressure
The weed cutter fits into a broader agronomic strategy to control weeds without relying solely on chemical solutions.
Adapted to large-scale crops
Wheat, barley, lentils, sugar beet and many other crops: the weed cutter meets many field needs in both organic and conventional farming.
What is a weed cutter used for in large-scale crops?
A cereal weed cutter can be compared to a weed mower. It is used when weeds grow above the crop canopy, such as wheat, barley, lentils, sugar beet or other crops depending on the agronomic context.
Its role is simple: cut the upper part of the weeds to prevent them from producing seeds. This action helps slow their spread within the field and strengthens an effective mechanical weeding strategy.
This technique is particularly valued in organic farming, but it is also used by conventional farms seeking to reduce herbicide use and better control weeds.


The Selac: the Bionalan weed cutter designed for performance
Bionalan has been developing its weed cutters for several years with a field-oriented approach, focusing on key factors such as cutting consistency, machine stability, available power and operational capacity.
To meet these requirements, the Selac range is built on a robust architecture and optimized operation. It notably combines slow knife rotation, high available power per meter and a system combining rotating knives and counter-knives to improve contact with the weed stem.
The machine can also be equipped with a hydraulic power unit with either a single or double pump, including a cooler and a 140 L HV46 oil tank.
Its design and finish aim to ensure durability, consistent performance and reliability under demanding large-scale farming conditions.
