An apparatus for use with rotating feeder, having an animal activated feedwheel for spreading feed within a trough. A first stopper is connectable to, and extendable from, the feedwheel. The first stopper defines an orbit path when the feedwheel is rotated. A second stopper is connectable to and extendable from a stationary portion of the feeder and into the orbit path. When the first stopper engages the second stopper, the stoppers cooperate to limit rotation of the feedwheel to a single direction about the aperture axis.
