New ABRAH cultivator by DULKS – Hoeing right next to young, tender plants

November 10, 2019 0 By Luis Garrison


We are DULKS, a start-up company working in
organic farming technology. We developed the ABRAH, a new cultivator for weed control.
Here you can see the prototype: It can hoe in immediate proximity to young, tender crop
plants, which means that we can, for example, hoe in between double or triple rows of carrots. We have also tested the cultivator in onions,
sugar beet and rocket. The ABRAH delivers great results in small, young crops in particular,
where it clearly outperforms other competing products. Here we can see the ABRAH being tested. We
are working in a maize crop which unfortunately is a bit tall already. Nonetheless, I hope
you can see how the ABRAH operates: We mounted two different tool types – or “tool groups”
as we call them – to the front and back axles respectively. The function of the tool in
the front is to cultivate the soil, to break up lumps and crusts and thus to ensure good
crop nutrition. By means of a chain it also drives the “tool group” in the back. And here we can see the rotary sweeps. The
advantage of rotating sweeps is that they don’t get bunged up with weeds or harvest
residues. Because our sweeps rotate more quickly we can even lift weeds right out of the soil. Our ABRAH was developed in cooperation with
piloting farms. It will go into pilot production and be sold to the first customers ahead of
the 2018 growing season. Our ABRAH costs roughly 1500 Euros per unit.
Each unit has a working width of 24 cm – the width of a bed top. The discs can be individually
adjusted and can therefore be set for any row width and distance between rows. The working
width can be adjusted by increasing or decreasing the number of units used. The ABRAH can be
mounted on all proprietary cultivator frames and is therefore also available for retrofitting.
