A spreading apparatus, which is self-propelled or towable by a towing vehicle, for scattering spreading material, in particular sand or soil substrates, onto a ground surface, having a container for the spreading material and at least one spreading unit by means of which the spreading material included in said container is adapted to be scattered, wherein said spreading unit comprises: - at least one rotatable spreading disc which is substantially parallel to the ground, - at least one drive device for rotating said spreading disc about the axis of rotation such that the spreading material is adapted to be scattered by means of said spreading disc and by virtue of centrifugal forces, - wherein a limiting device is arranged at least in a portion of the circumferential region of said spreading disc which prevents the spreading material from being scattered in this portion of the circumferential region, - wherein the position of said limiting device relative to said spreading disc is adjustable such that the direction in which the spreading material is adapted to be scattered is variable, - wherein the spreading disc is rotatable about an axis of rotation, wherein the limiting device is pivotable about said axis of rotation such that said limiting device is adapted to be placed in different circumferential regions of said spreading disc, wherein during adjustment of the limiting device the spreading width at which the spreading material is adapted to be scattered remains constant, characterized in that the limiting device configured as a sheet metal element comprises at its upper and lower free ends a sheet metal edge (38, 40) protruding towards the spreading disc, wherein the lower protruding sheet metal edge is arranged beneath said spreading disc and the limiting device is arranged at a defined distance of less than 1 cm to the spreading disc. - at least one rotatable spreading disc which is substantially parallel to the ground, - at least one drive device for rotating said spreading disc about the axis of rotation such that the spreading material is adapted to be scattered by means of said spreading disc and by virtue of centrifugal forces, - wherein a limiting device is arranged at least in a portion of the circumferential region of said spreading disc which prevents the spreading material from being scattered in this portion of the circumferential region, - wherein the position of said limiting device relative to said spreading disc is adjustable such that the direction in which the spreading material is adapted to be scattered is variable, - wherein the spreading disc is rotatable about an axis of rotation, wherein the limiting device is pivotable about said axis of rotation such that said limiting device is adapted to be placed in different circumferential regions of said spreading disc, wherein during adjustment of the limiting device the spreading width at which the spreading material is adapted to be scattered remains constant, characterized in that the limiting device configured as a sheet metal element comprises at its upper and lower free ends a sheet metal edge (38, 40) protruding towards the spreading disc, wherein the lower protruding sheet metal edge is arranged beneath said spreading disc and the limiting device is arranged at a defined distance of less than 1 cm to the spreading disc.
