摘要

Soil cultivating machine comprises coupling points for connection to a towing vehicle and at least two rows of hollow disks (10) lockably connected to a support frame and rotating about vertical axes (13). The working direction of the hollow disks alternates from row to row. The working angle (a) of the hollow disks of at least one row is adjustable about an ideal center of rotation located in the working position in the region of the lower third (30) on the imaginary disk surface (20) of the hollow disk. Preferred Features: More than two rows of hollow disks are provided. The working angle of the hollow disks of at least the two rear rows, preferably all the rows, is adjustable.
