High-precision post driver machine

A machine suitable for driving posts into a ground at predefined locations with centimetric precision, for a vineyard or orchard trellising structure, the machine comprising:

• a vehicle chassis
• an electronic control unit,
• at least one GPS sensor,
• a driving column mounted on the vehicle chassis, via an articulated positioning adjustment system,
• the driving column comprising a pole and a slide mounted so as to be able to slide with regard to the pole, in a substantially vertical manner,
• a driving bell mounted on the slide,
• a post guiding device, which comprises a gripper mounted on the slide and a guide shoe mounted at a base of the pole,
• the guide shoe being able to move between a working position and a retracted position, the articulated positioning adjustment system allowing the driving bell and the post guiding device to be positioned directly above one of the predefined locations and to drive a post in vertically at the one of the predefined locations,
• wherein the guide shoe comprises a recess for receiving the post when the guide shoe is in the working position thereby guiding the post during insertion into the ground, and
• wherein the guide shoe is rotatably mounted with an axis substantially parallel to a longitudinal axis of the vehicle chassis, wherein the axis is located at a distal end of the pole and the retracted position being raised relative to the working position.
