ABSTRACT:
A mechanical grape harvester for trellis-supported grape vines having relatively rigid shaker members for engaging and shaking the rigid trunk structure of the vine and having relatively flexible striker rods for striking against the limber portions of the vine growth trained along the trellis wire. The shaker members and striker rods are both operated at minimal speeds to reduce leaf removal and plant damage.
