An apparatus for selecting horticultural products includes an intake section leading to at least one passage lane defined by a pair of mutually close stems rotatably supported by a support and movement assembly and are interposed longitudinally between the intake section and a discharge section. between the pair of stems, kept inclined downward from the intake section to the discharge section, a longitudinal slot is disposed that can be crossed exclusively by debris and horticultural products having dimensions that are smaller than the width of the slot. The assembly includes a drive unit meshing with an end portion of each stem proximate to the intake section and elements for the free support of an end portion of each stem proximate to the discharge section.

A flexible scraper for a grader or other solid object processing system. The flexible scraper is adjustably mounted to a frame and contacts a rotating roller to clean the rotating roller or prevent components from wrapping around the roller, as well as maintain products within designated lanes. Connectors allow insertion and release of the scraper into and from the frame. The flexible scraper is inserted into slots in the frame and held against the rotating roller by gravity.
