1. A detection device for metal stakes in a wire-trained plant-crop hedge, comprising at least one metal stake detector designed for being moved parallel to a trellis plane of the hedge and arranged for generating a detection signal when it passes next to a metal stake of the hedge which comprises metal stakes, wherein said at least one metal stake detector comprises a first and a second metal detector arranged for generating respectively a first and a second measurement signal when they pass next to one of the metal stakes of the hedge, where said first and second metal detectors are mechanically secured to each other in movement and arranged for being spaced vertically relative to each other during use of said device, where the detection device further comprises an electronic management unit for said first and second detection signals, configured for receiving the first measurement signal and the second measurement signal and for, upon detection of a temporal offset (Δt(incl)) between the maximum variation levels of the first and second measurement signals, generating a signal (Sincl) indicating an inclined state of the metal stake relative to a vertical direction (Dvert) in the trellis plane.
