Tru-Flow spreaders handle the toughest of conditions. For top-dressing to be effective, it needs to be applied as uniformly as possible. Tru-Flow's unique 8" dispersal drum is encased in expanded metal. Conventional drop spreaders rely on gravity to help release the Har-Tru from its hopper; but the Tru-Flow pulls the surface out of the hopper and on to the court with unmatched consistency. TruFlow Spreaders will distribute Har-Tru as well as sand, other materials for synthetic grass, natural turf, and running tracks. If cleaned properly to protect the steel, this unit will give years of service. Larger tow models for heavy-duty use are available.
