A powered riding trowel comprises a protective, quick access support shroud that may be unlatched to quickly expose the power means for service without structural disassembly. The trowel seat is mounted on top of the upper planar surface of the shroud. The shroud front and rear are preferably formed from rigid, supportive material having airflow pathways for cooling and ventilating the shroud interior. Opposite shroud ends integral with the top surface angularly depend outwardly and downwardly. In the best mode one shroud end is hinged to the trowel frame, and the opposite end is releasably coupled to the frame by spring biased latches. The preferred hinge structure comprises an outer hinge portion formed by a pivotal connection of the bottom of one shroud end. A cooperating inner hinge defined by at least one pair of inner braces is coupled to a pneumatic dampener that pivotally terminates within the shroud interior. Because of the twin hinge construction, shroud movement is defined by a pair of separate but similar arcs, resulting in precisely controlled shroud deflection. In an alternative mode both shroud ends are releasably coupled to the frame by spring biased latches.
