ABSTRACT:
A picking head for a mechanical grape harvester, the picking head having an oscillatable frame and a pair of opposed shaker rails supported on and below the picking head frame. Two sets of longitudinally spaced counterweights are mounted on the picking head frame for rotation about vertical axes, each set including upper and lower eccentric weights. The weights are rotated so that the longitudinal forces cancel out and the transverse forces are additive. The rotative forces of the upper and lower weights in each set are 180.degree. out of phase with each other and related to each other in magnitude so as to minimize the amount of transverse reactive force transmitted from the picking head to the main frame of the harvester. A link suspension enables the center of oscillation of the picking head to be below the picking head frame.
