Abstract

The agricultural implement has a number of tool holders driven round vertical axes. Externally, each holder (11) is conical with the apex downwards, while in the direction at right angles to its axis of rotation (18) is has a curved shape (13). At the bottom, each holder can be oval or elliptical in shape, and at the top circular, or alternatively it can be oval or elliptical for its entire height. The holders can be so shaped that the distance between adjacent ones remains constant whatever their angular position.
