ABSTRACT:
A trowel blade assembly attaches to the drive arm of a concrete troweling machine by means of a mounting bar which is bolted to the drive arm. The mounting bar in turn is received by a U-shaped bracket which is bolted to the trowel blade and incorporates recesses formed so as to cover the threaded connections between the blade and the bracket to permit easy removal. A quick release fastener passes through mating holes formed in the bracket and the bar enabling rapid repositioning or replacement of the blade-bracket assembly when one or both of the working edges of the blade are worn.
