An educational toy that shows how watermelons and similar farm products are grown, harvested, and removed from the field in field trucks and taken to a packing shed where they are placed on conveyors and transferred to over the road trucks. These trucks take the melons to commission houses where they are put into wooden or cardboard bins. The bins are transferred to city trucks that finally deliver the melons to chain stores and fruit markets for sale. The various types of trucks and equipment are introduced at the appropriate time and all are manipulable by children in a teaching toy mode.
