An apparatus for separating objects of a particular kind from other objects, e.g. stones etc. from potatoes during harvesting, wherein the objects fall in a stream past a detector for objects of said particular kind and, after detection of an object, a separating member positioned downstream of the detector is moved in a manner in dependence on a physical dimension of the detected object so that objects of said particular kind are directed in a first direction and other objects are directed in another direction. The physical dimension may determine a time of movement of the separating member and/or whether the separating member should be moved at all.
