ABSTRACT:
A street sweeper drag shoe of cast austempered ductile iron used with a rotary broom in sweeping, whereby escaping debris from under a contact skid is recaptured. The street 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 street 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 ends of the broom. The contact skid exhibits total planar contact with the roadway without interceding carbide wear plates.
