Abstract
A device that prevents wrapping of long strands of fibrous material around an exposed rotating shaft has a stationary flange fixed to the chassis or bearing housing for the shaft and a rotating flange fixed to the shaft. The flanges are positioned to pass one another during each revolution of the shaft. When the flanges are nearest to one another, a loop of vegetation forms tightly around the flanges. Continued rotation of the shaft then stretches and tears the loop apart. This loop forming and tearing is repeated for each revolution of the shaft to effectively prevent fibrous material from wrapping around the shaft.
