The invention relates to a mobile apparatus for spraying a plant treatment liquid. This apparatus comprises a support member carried by a tractor or trailer vehicle. A rectangular framework is suspended from the support member through an articulated link rod, a ball joint and an articulated component, for instance an articulated parallelogram. Two rigid components of variable length, for instance two jacks, are interposed, the first one between the rectangular framework and the articulated link rod, and the second one between the support member and the articulated component. The length of each rigid component is adjusted in operation so that the lateral sides of the rectangular framework are always parallel to and equidistant from the longitudinal plane of symmetry of the vehicle.
