The invention relates to a soil-working device (1) for row plantations, which has a frame (2) and at least one beam (3), on which at least one finger-weeder tool (9) 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 to a method for the height guidance of at least one finger-weeder tool above a row in a row plantation, wherein the soil-working device (1) 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.
