ABSTRACT:
The invention relates to a soil working device, comprising a substantially cylindrical soil working member, which is mounted between two main supporting arms for rotation about a substantially horizontal axis and is axially composed of a number of sections which are mutually connected and connected with two shaft end sections journalled in said main supporting arms respectively through couplings of the universal type, the coupling between each two sections being supported by an auxiliary supporting arm which extends into the travelling direction and pivotally engages a connecting bar extending between said main supporting arms parallel to and in front of said soil working member. According to the invention both the axis of the soil working member and the connecting bar are located at substantially the same level, so that the auxiliary supporting arms are disposed in a substantially horizontal position and the rotational axis of the working member will be kept, as viewed in plan view during operation, substantially straight.
