An apparatus for the mechanized displacement of movable wires arranged on opposite sides of a row of plants, in particular grapevines, includes a frame suitable to be removably mounted on a farm vehicle, the frame being provided with a mover configured to move the movable wires. The apparatus is characterized in that the mover includes a pair of opposite gripping elements, each of which being suitable to slidingly receive one of the movable wires, the gripping elements being movable in a sequential and synchronized manner along at least two orthogonal axes so as to displace the movable wires from a first height to a second height.
