  • Patent number: 4069652
    Abstract: Harvesting apparatus particularly suited for picking citrus fruit, apples, and the like, has an adjustable boom mounted on a vehicle with a harvesting head secured to the free end of the boom for tilting and turning to either side and for forward and rearward tilting. A flexible and longitudinally expansible tube carries the picked fruit from the harvesting head to a suitable receptacle. A preferred embodiment of the harvesting head has a resiliently surfaced roller mounted for rotation in either of opposite directions between resiliently surfaced side walls of the head. As the roller gathers the fruit from a tree limb, the roller deposits the fruit in a passageway between the roller and one of the resilient side walls and rotates the fruit as it passes through a nip portion of the passageway, to release the fruit from the limb, and then release the limb from the harvesting head.
