ABSTRACT:
A sweeper drag shoe used with a rotary broom in sweeping, whereby escaping debris from under a contact skid is recaptured. The sweeper drag shoe contains a deflection plate that redirects bristle tip movement inwardly to allow the broom to recapture debris which escapes during normal operation. The sweeper drag shoe also includes an angled wedge for concentrating outer bristles of the broom into a rotating barrier to prevent debris migration to the end of the broom.
