A CVT transmission for agricultural tractors which envisages equipment for continuous variation of the motion by means of an epicyclic gear train. In the CVT transmission the input of the motion from an engine occurs in a direction substantially that is parallel to an axis of longitudinal symmetry of the tractor, whilst the axes of a shafts, respectively, between which there takes place variation of the transmission ratio, are transverse with respect to the axis of longitudinal symmetry of the tractor.
