ABSTRACT:
A soil working machine pivotably mounts at least one rotor having serrated working elements. The rotor is pivotally connected at each end to a frame beam by a pin which can be inserted into either one of two holes located one above the other. The hole chosen governs the resistance to upward pivoting of the rotor. The machine can be hitched to a tractor either with the frame beam substantially transverse of the intended direction of operative travel, or with the frame beam inclined to this direction. Each rotor has end plates that mount forward blades and the outer plate supports a gear transmission to the rear of the respective blade.
