Mechanical weeding reduces reliance on chemical inputs

Kverneland mechanical weeders provide a variety of solutions for growers considering all aspects of weed control, whilst reducing chemical input. Weeder models include the Helios – a star-wheel equipped rotary hoe suited to cereal crops; and the Onyx tined hoe, for inter-row applications.

At 6m wide with a hydraulic folding frame, the Helios rotary hoe uses pairs of cast iron star wheels whose downward pressure is adjustable. This affords delicate control to suit the surface conditions of the field in combination with a crop’s growth stage, to carry out shallow weeding through the top 10mm of soil. The shallow weeding restores the water and airflow, increasing mineralisation and promoting the absorption of nitrogen, which results in improved tilling of the crop for healthy plant development.

“The Helios can provide an effective mechanical solution for black grass control, with the star wheels capable of pulling out small weeds and leaving them on the surface to wither and die without impacting on crop growth,” explains Kverneland soil specialist Adam Burt.

In use, the star wheels carry out 60% of the weeding process, with its following harrow accounting for 40% of the cultural control process.

For arable row crops such as maize, sugar beet and vegetables, the Kverneland Onyx offers an inter-row solution to reduce reliance on herbicides. The Onyx can be combined with the Kverneland Lynx guidance interface for enhanced precision.

The guidance interface sits between the weeder frame and tractor’s three-point linkage and can be equipped with up to two, forward-facing colour scanning cameras to provide active side-shift.

With camera and control panel technology provided by Tillet and Hague, each inter-row weeding assembly can also be equipped with section control, with automatic raise and lower available through ISOBUS control.

Camera guidance ensures the hoe is positively steered to deliver high accuracy even at high forward speeds. Onyx offers 3-12m working widths, and can be equipped with a variety of weeding solutions including bolt-on Duck foot or flat A-shares.
