Potatoes are sorted from stones &c. by the action of a transversely disposed row of fingers 36 which are deflected or not according to the result of a scan by a sensing unit 16 as the potatoes are discharged from an endless conveyer belt 18. Each finger 36 is connected to a respective pneumatic motor 38 (Fig. 4). The depth of the potatoes on the belt 18 may be regulated by the action of a series of rollers 20 which may be driven. An adjustably mounted rotating comb-like paddle 25 may be associated with the rollers 20 to assist the passage of large objects and so prevent them from being held on the upstream side of the rollers 20. A transistor current-amplifier for the sensing unit is described (Figs. 5, 6, not shown).
