Tree crops such as citrus fruit is harvested by a mechanical picker by advancing a series of rotating disks into the tree where the disks engage the fruit and pull it from the tree. The picker includes a housing having wheels for movement between rows of trees with a drive gearing assembly in the housing powered from a tractor. Two disk assemblies, each comprising a pair of longitudinally spaced elongated support arms having inside ends supported on the housing, have outside ends supporting a shaft extending longitudinally between the support arms. The disks are arranged in pairs at longitudinally spaced intervals along the shaft with adjacent disks of each pair having oppositely facing surfaces. The arms can be raised and lowered to force the disks into the tree canopies from top to bottom of the trees.
