A grape harvesting apparatus has a portal-type chassis adapted to travel along the ground in a predetermined direction and having two vertical supports elongated in the direction and at least limitedly horizontally movable on the chassis. These supports normally flank an upright median plane extending in the chassis travel direction. Respective pluralities of vertically spaced and horizontally extending beater wires on the supports each have relative to the travel direction a front wire end attached to the respective support, a forward wire portion inclined inward and backward toward the plane, a rear wire portion generally parallel to the plane, and a rear wire end attached to the respective support behind the respective front end. A drive is provided on the chassis for synchronously and oppositely displacing the supports with the respective beater wires transverse to the travel direction while maintaining the supports generally parallel. Thus grapes will be shaken from grape vines between the beater wires.
