Abstract: An apparatus for soil working, consisting of a frame (1) drawn over the ground by a vehicle, a first roller (7) mounted rotatably in the frame (1), extending transversely to the travelling direction, a second rotatably supported roller (19) arranged parallel to and behind the first roller (7) and driven thereby through a transmission (17), and two or more rows of soil working members (6) fixed to the frame, wherein the first roller (7) extends between two rows of soil working members (6), and is mounted adjustably in height an securably with respect to the frame (1), the second roller (19) being coupled either to the frame (1) or to the first roller (7) by two or more vertically moveable swing arms (20), so effectuating a precise pressure on the ground of the first (1) or alternatively the second roller (19) independently of one another, and also by maintaining an exact setting of the soil working members (6) at a specific level.

Abstract: A device for digging up tuberous plants, for example beets, comprising pairs of lifting members formed by driven shafts slanting towards one another and being provided at the lower ends with lifting bodies, wherein each lifting body has a pressing face extending, viewed in an axial direction, along a helically curved line relative to the rotary axis, such, that the lifting body will gradually penetrate into the soil owing to the helical shape while the quantity of earth sticking to the beet is materially reduced and consequently the tare of the dug-up beet or tuber is considerably reduced as well as the cleaning expenses for the user.
