Abstract
A suspension and support system for shaker elements of a mechanical harvester wherein a generally horizontal shaker element support is suspended from the frame of the machine by a pair of generally vertical links pivotally connected at their lower and upper ends respectively to the shaker element support and frame, the links being of unequal length so that the unequal swinging movement of the links relative to the frame will result in a solely horizontal movement of the shaker element which is mounted on the end of the horizontal support member. The pivot connections have no relatively moving, interengaged surfaces so as to prevent sticking of such connections in the event juice accumulates thereon.
