Abstract
A biasing system for use with an associated run selector device includes a valve body member movable within a housing between opposite first and second run selection positions selecting respective first and second commodity distribution runs of the associated run selector device. The biasing system includes a first biasing element on the housing, and a second biasing element on the valve body member. The first and second biasing elements are movable relative to each other between opposite first and second biasing system positions together with the associated valve body member being moved relative to the housing between the opposite first and second run selection positions. The first and second biasing elements are mutually biased against each other to urge each other apart and towards a one or the other of the opposite first and second biasing system positions.
