  • Patent number: 3953960
    Abstract: An apparatus for removing fruit, particularly citrus fruit, from a tree comprises a composite picker roll containing a plurality of axially spaced apart segment wheels. Each segment wheel has a plurality of resilient, arcuate pressure members for engaging the fruit being picked. The roll is mounted within a housing and coupled to a hydraulic motor for rotation. A plurality of free floating fingers, resiliently mounted to the housing, is positioned parallel to the roll and in juxtaposition to each other. The fingers are aligned one-to-one below the roll segment wheels and are spaced apart therefrom to form channels through which fruit is conveyed. During picking, the resilient pressure members of the roller segment wheels, cooperating with the free floating, resilient fingers, provide multiplanar rotation of the fruit to efficiently snap the fruit from the tree branch without tearing the skin of the fruit and without breaking the branches or disturbing delicate blossoms on the branches.
