The invention relates to a system for fixing spiral teeth onto a machine intended for preparing the ground, of the cultivator type. In contrast to the known principle of the caliper plate assembly, which necessitates high labour and parts costs, the system proposed is simple to manufacture and rapid to install. It comprises a thick angle bracket, whose lower flange, which is pierced with square holes, is tangential to the inner face of the upper flange. The holes 5 serve to position and guide the shank 3 of the tooth. The upper flange, fitted with a stiffening rib 8, has a row of holes which are perpendicular to the square holes. The tooth can thus be held by a single bolt 1 which strengthens the connection of the shank 3 of the tooth onto the angle bracket 2. <IMAGE> |
