Abstract: A harvesting apparatus has a harvesting head suitable for connection to a traveling carrier and suitable for straddling a row of fruit-bearing plants. A straddling carrier has the harvesting head mounted thereon. An actuator arrangement is provided and is cooperative with the harvesting head so as to move the harvesting head in relation to a median plane of the straddling carrier. A centering mechanism is cooperative with the harvesting head so as to center a lower portion of the harvesting head in relation to the row of fruit-bearing plants. A controller is cooperative with the centering system.
