Abstract: A potato harvester chain conveyor has a plurality of rods spanning between support portions providing spacing to retain potatoes by allow soil to drop through. The spacing may be field modified by adding resilient split sleeves on the rods. The invention includes the sleeves, method of attachment, methods of removal, and the sleeves in combination with the conveyor and/or the harvester with the conveyor.

Abstract: A pick assembly for delivering a seed product from a supply thereof to a delivery location and having a pick wheel and at least a first pick arm assembly on the pick wheel with a first cantilever-mounted pick. The pick: a) penetrates a seed product from a supply and releases the seed product to a delivery location as an incident of the pick wheel turning. The first pick has a body with an exposed surface that tapers over at least a portion of the length of the body. At least one discrete raised holding element is on the exposed surface of the body and has an axial width bounded by axially spaced edges. The one holding element at least one of: a) extends through less than fully around a lengthwise axis of the first pick body; and b) has gaps at both axially spaced edges, each extending along the lengthwise axis a distance greater than the axial width.
