The invention relates to a device for optically guiding agricultural vehicles. The optical guidance device intended to be mounted at the front of an agricultural machine or tractor 1, which drives it, essentially comprises a U-shaped post, mounted at the front of a tractor 1 by means of a vertical support 6 and two catoptrical systems which are symmetrical about an axis XX of the post and which each comprise three planar mirrors: an upper mirror 3, a middle mirror 4, and a lower mirror 5, which are arranged on each of the flanges 2a and 2b of the post 2, thus allowing the driver of the vehicle to follow an itinerary located at a set distance from a given line. <IMAGE>
