Abstract

One or more elongate barriers are provided that are movably (in one configuration pivotably) mounted proximate the outside of a grass cutting deck. When one of the barriers encounters a foreign object in a certain manner, the barrier moves towards its “tripped” position, thus causing a corresponding change to the operating characteristic of the lawn mover, be it a termination of the cutting process, the mower drive process, or both. The barriers can be used with electric or mechanical control elements.
