  • Soil-working device; method for the height guidance of at least one finger-weeder tool above a row in a row plantation
    Patent number: 10238021
    Abstract: A soil-working device for row plantations has a frame and at least one beam, on which at least one finger-weeder tool is arranged, which in particular can be designed to be passively drivable and which is oriented at a setting angle to the soil in a working position for soil working, and a method height-guides at least one finger-weeder tool above a row in a row plantation, wherein the soil-working device has at least one height-guiding apparatus, which keeps the setting angle of a finger-weeder tool in the working position constant and which can be designed advantageously in such a way that the height-guiding apparatus enables the height guidance of further soil-working tools which are operated next to the finger weeders and which thus can likewise be guided in height.
