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.
