ABSTRACT OF THE DISCLOSURE A power driven twin trowel cement finishing machine in which two sets of counter rotating troweling blades have intersecting circular trowling area, each set of troweling blades being carried by a rotatable shaft upon which the blades are supported and arranged for remote relative adjustments from a guiding handle of the sets of troweling blades to vary their troweling angle with respect to the associated cement surface. The two sets of trowel- ing blade assemblies have their rotatable shafts supported for relative tilting movements in opposite directions from a normal generally vertical position to selectively oppositely inclined planes of rotation of the sets of troweling blades in a manner to generate reactive blade forces that will be operative to bodily propel the machine either in a forward or reverse direction, while permitting manual lateral controlled movements of the machine by means of the guiding handle. Remote control mounted on the guiding handle is operable to vary the orientation of the planes of rotation of the sets of troweling blades and the consequent propelled direction of movement of the machine.
