ABSTRACT:
The present mounting apparatus includes a pair of retaining tabs secured to an upper surface of a blade adjacent leading corners. Each retaining tab includes a side wall, an end wall and a cover plate which forms a cavity with the blade upper surface. A pair of retaining tabs are secured to the upper surface of the blade adjacent trailing corners. The four retaining tabs cooperate to removably secure the blade to a trowel finishing blade without the use of mechanical fasteners.
