This article briefly describes the various areas of research presently underway, by University of California and U. S. Department of Agriculture, aimed specifically toward total citrus harvest mechanization. The article considers: (1) the phases of work being performed, (2) the relationships of the phases to the overall objective, and (3) the coordination of the work among the research disciplines. It also points out that at the present stage of research, the total mechanization of California citrus harvesting is not imminent.
