Abstract: A produce weighing and selecting mechanism is disclosed where the feed system 8 is driven by a single drive means. The feed system 8 contains roller conveyors made up of rollers of discontinuous diameter alternating with rollers of constant diameter where the discontinuous rollers are rotated in a direction opposite the direction in which the conveyed objects are driven in order to sort the objects by size, before their presentation to a second transport means which presents the sorted objects singly to a third transport means. The third transport means possesses arms which gather up the singulated objects and transport them to a weigher, which possesses a slotted plate to support the object to be weighed as the arms of the third transport means pass through the slotted plate. Weighed objects are then ejected to a packaging apparatus.
