Top-dressing and resurfacing Har-Tru clay courts is a demanding task. Tru-Flo spreaders are designed to make top-dressing and resurfacing as easy as possible. Tru-Flow's unique 8" dispersal drum pulls the Har-Tru clay court surfacing material out of the hopper and onto the court with unmatched consistency. Tru-Flo's ground driven dispersal system means that there are no hydraulics, pumps, or engines to malfunction, leaving no possibility of oil leaks on your court. The 36" Tru-Flo spreader can also be used to distribute sand or other infill material onto synthetic turf courts. This 36" Hand Model Tru-Flo will hold up to eight (8) 80 lb. bags of Har-Tru.
