Each bank can be moved toward or away from its upright by one adjustment mechanism, and another mechanism is provided for tilting the bank about its longitudinal axis. In addition, the uprights are pivotally mounted on a common base, and can be tilted outward from their normal vertical position, to provide access to the picker heads for cleaning.
