The first and second members are moveable by the relative movement into a first posi0 tion providing the dosing opening with a first opening size and a second position different from the first position and providing the dosing opening with a second opening size different from the first opening size, wherein a center portion of the dosing opening is locally fixed when the first and second members are moved between first and second positions. Further, a dosing system for a spreader machine for distributing a granular material or the like comprising the assembly is 5 provided. A spreader machine for distributing a granular material or the like is provided. (Fig. 3)C~(N U) co coV C 04
