ABSTRACT The soil loosening device has at least one, preferably two journals protruding downwardly from a supporting body, which are driven to a pivotal motion along a limited angle. Tine-like soil loosening tool members in bifurcate arrangement, to be driven along a circle segment, are mounted on the journals. The driving unit for driving the tools is characterized by its simple design since it consists of only a few, reliably guided and sturdy components. Particularly, there is provided a crank shaft which drives a toothed rack member to an oscillating motion. Gear wheels connected to the journals mesh with the toothed rack member. Accordingly the expenditure in manufactur- ing the device is low and the device has a high resistance to wear. The driving unit of the device may be attached to the supporting body in different angular positions by means of a coupling device.
