Abstract
Power driven cement finishing apparatus having a plurality of finishing trowel blades rotatable about a common vertical axis, a stationary guard ring being supported from a main frame structure of the apparatus so as to be positioned above and outwardly of the path of rotation of the outer end tips of the finishing blades, and vibration absorbing means being interposed between the guard ring support and the main frame structure, whereby vibrations induced in the guard ring during operation of the apparatus will be dampened and not transmitted to the finishing blades.
