<p>The tool has a mixing assembly constituted of two pairs of rotative coaxial drums (28) arranged on both sides of a support unit. The drums include supports (42', 42'', 42''') equipped with cutting teeth (40', 40'', 40''). One of the supports is inclined at an angle of 10 degree with respect to a plane (P) to axially arrange an exterior face between the one of the teeth and an interior face, so that the tooth is arranged axially beyond the exterior face such that the tool drills and mixes volume of soil that is axially thicker than axial length (L) of a peripheral surface of each drum.</p> |
