<p>The assembly has a chassis, and two symmetrical tool holder sub-assemblies with a tool support (31) and an articulated probe (4) activating a hydraulic jack adapted to displace a tool (33) to avoid direct contact of the tool with plants. Sensors (51, 53, 54) are adapted to detect a vertical variation range of the tool with respect to a ground and lateral variation with respect to the plants. Hydraulic jacks automatically correct each variation in a manner to maintain the tool and tool holder in optimal work position with respect to the ground and the plants.</p> |
