This invention relates to a flexible endless conveyor for a harvester pickup apron made up of a number of side-by-side rubber belts. Each belt has an integrally molded series of main cleat attachments for rigid tines. Each tine is set astride a central cleat while the leading and trailing edges of the tines are held by undercuts in a pair of subcleats which are perpendicular to each main cleat. The subcleats prevent any debris from lodging under the body of the tine during crop harvesting.
