Abstract
A high performance, multiple rotor, hydraulically driven riding trowel for finishing concrete includes a rigid trowel frame with two or more downwardly-projecting, bladed rotor assemblies that frictionally engage the concrete surface while supporting the trowel. The rotor assemblies are tilted with double acting hydraulic cylinders to effectuate steering and control. A seating arrangement supports an operator. A special ventilation path is provided to prevent overheating of the operator area. cooling compartment adjacent the seating region, Pathways are established by a cooling compartment enclosed by a shroud having at least one side ventilation orifice, a cooler assembly disposed within the cooling compartment; the cooler assembly comprising a grill, a plenum with a heat exchanger adjacent said grill and a fan adjacent said heat exchanger, the plenum having open sides and a closed bottom to prevent air pathways through the seating region.
