Abstract
A horizontal force balance shaker includes a horizontal shaking head supported for horizontal movement by parallelogram linkages. Counterweights are secured to concentric shafts for rotation at the same speed in opposite directions about an axis thereby causing the shaker head to oscillate horizontally. The axis may be oriented horizontally or vertically, and the shaking head may be advantageously used in row crop harvesters such as grape harvesters.
